Significance of Physical Performance Tests †MyAssignmenthelp.com

Question: Discuss about the Significance of Physical Performance Tests. Answer: Introduction: Pain in the lower back is such a discomfort that is situated under the costal boundary and over the inferior gluteal folds, such pain occurs with or without the leg pain. It is such a pain that happen posterior in the area among the margin of lower rib and the proximal thighs. The pain in the lower back is categorised into three subtypes that are the acute, sub acute and the chronic pain in the lower back (Ikwugwalu, 2016). Such subdivision of the pain is based on the pain duration. Lower back pain in it includes history of complain and trauma of the pain with diffuse, groin, leg pain and nonspecific hip radiation. The pain in the lower back that is continuous for the longer period of more than three months is considered as the chronic pain management. Around 80% of the costs related to the health care are accredited tounceasing LBP (Alemo Sayadipour, 2008). The main source related to the pain is intervertebral disc. Treatment of the pains needs the multifactorial approach, for the reason that pain is very multifarious. The treatment of the pain includes the long course of the antibiotics among the certain population (Pfingsten, Lueder, Luedtke, Petzke Hildebrandt, 2014). The pain that is observed in Sue was the result of ageing and is being experienced from the last one month only. The beginning of distracted low back pain involves a variety of factors, and socio-psychological factor are also considered as a significant cause, beside physiological and structural abnormalities in the lower back. The spinal segment L3-L4 is located in the centre of the lumbar spine; act significantly to support the weight. The muscles, nerves and other delicate tissues in an agreat way assist the processes such as the foot motion and knee extension. The condition of the back pain is Sue was the result of nerve compression which includes the symptoms of numbness, tingling, and weakness. The significance of the pain is as a result of the degenerative changes in the spine (Sasaki, 2013). The pain experience by Sue is mild and includes certain therapies such as interferential therapy and hot packs to reduce the pain as the pain is a pain is as a result of narrowing intreverterbral foramen a usual traction of the inferior spin with receiving the pain (Sasaki, 2013). The pain in the lower L3-L4 mainly is due to the reason of disc becoming herniated which results into an unwanted contact between the nerve and the disc which in turn causes the pain. The source of the pain in the lower back is as a re sult of the surrounding ligaments and muscles that are irritated and inflamed as a result of ageing (Goodman, Stehr Agarwal, 2011). The other significance of the pain is due to the enlargement of the facets point which narrows the open spaces of the spine and hence causes the compression of the spinal nerves and in case of the Sue, the disc is degenerated naturally due to age factor which changed the disc motion and thus resulted in the stiffness (Eguchi, Ohtori, Toyone Ozawa, 2011).

A Comprehensive Guide on How to Write an Engineering Essay

A Comprehensive Guide on How to Write an Engineering Essay Engineering is one the most complicated scientific disciplines that in particular offers broad topic choices and appliances to both academic performance and real-life situations. Therefore, an engineering essay writing isn’t an easy task. There are some factors of good essay writing that make such a mission almost impossible for most students to compete at the highest possible level. First and foremost, you should choose a valuable essay topic even if the approximate field of study is given Engineering. What is little-investigated in Engineering today? Remember that engineering belongs to exact sciences the terminology of which is highly specialized. The appropriate use of relevant engineering terms is the essence of your engineering essay. Concentrate on the content of your paper that should be informative for the audience using the proper academic vocabulary and strong facts. In the meantime, read 10 fun and exciting facts about engineering provided by the national society of professional engineers. Finally, you shouldn’t forget about the standard structure of an essay that shows the logical flow of thoughts from general points to specific ones with logical conclusions. The structural integrity of the text makes an essay look well-structured and easy to follow. When you are ready to start the endeavor to write a good essay on Engineering (and you need to get ready to write essays successfully if you want to finish your studies on Engineering or cross-disciplines), do all your best immediately at the beginning of the writing process. Key Pre-Writing Tips to Set You Right on the Productive Writing Stage It is evident that any productive process is comprised of some key steps. So to write a comprehensive engineering essay that would appeal to the target audience, you should have a plan of action and milestones. Think of all points your essay should have a well-chosen topic, a well-developed outline, a thesis statement, the main parts with the relevant ideas, etc. There are some pre-writing tips that you’ll find useful for your essay writing that should be coherent and logical. The primary aim of an essay author is to determine the audience that will read a particular piece of writing and the purpose of essay writing. It allows to set the tone for the content and establish the approximate ultimate effects of the essay demonstrative, informative, convincing, etc. One of the most often used reasons to start an engineering essay is to have an excellent academic performance that depends on the successful assessment of every single essay. Then, it is significant to choose a good essay topic on Engineering that can be found in this guide as well. After you determine the target audience and the purpose of your writing, it is much easier to choose a topic. The first demand of this endeavor is to follow what is defined in the requirements of your assignment given by your instructor(s). For example, your instructions are as follows below: You need to write an essay that is a three-part paper that develops a position in response to the essay question: What are the critical issues raised in Engineering during the 21st century? Find some relevant examples that support your argument. In the case when the topic sounds too general, you should appeal to your own preferences concerning what issue in Engineering you consider as the most critical and why. Almost any subject in the engineering sphere will suffice for writing a good essay to the fullest extent. Remember that a poor example of topics in engineering is a general, non-debatable theme because this science requires a narrow approach with deepening into the main analysis of the theory and practice. The following examples represent some proper topics for the engineering essay that can guide you on how to choose your own topic: Achievements of Engineering in the Android App Development; The Management of Engineering Projects; The Significance of the Renewable Energy Industry for the Future of Engineering; A Closer Look at the Commercial Work in Engineering and Its Relevance for the Industry; How Can Engineering Help with the Reduction of Pollution in the World? The History of Engineering Assistance in Exploring the Mining Industry; How Far Has the Genetic Engineering Come Today? Is It possible to Entirely Replace the Human Labor with Robotics? How Can Engineering Help with Reducing the Costs of Manufacturing in Every Possible Industry? 7 Appliances of Engineering Achievements in Little-Investigated Fields of Study Like Medicine or Public Services; Investigation of Some Engineering Mistakes in the Aviation Field; The Modern Application of Aerodynamics and Fluid Mechanics; Materials and Structures Suitable for Better Bridge-Building; The Structural Organization of the Civil Engineering Units; Assessment of Electrical Engineering in the Telecommunication Field; Is Bio-Systems Engineering Going to Replace Biology, Chemistry, Computer Science in the future? The Engineering Background in Automatic Piloting and Its Effects on the Modern Aviation. These topics address some issues that are not only included in the assignments but represent the field of interest of most researchers and ordinary people. However, keep in mind that the given topics illustrate the broad set of variants and guide you in any particular direction of engineering research. Additionally, it is useful to introduce the basic crude notions that don’t serve as proper topic examples: Why Is Engineering Important? What Engineers Do? When Did Engineers Appear? All the mentioned examples aren’t interesting to work on as this information is easily found on the Internet today. Moreover, they don’t take into account the structural differentiation of engineering. Know that it includes such types as mechanical, civil, electrical, genetic, and others? If you are not familiar with the classification of the engineering field, you can find it at Engineer Jobs. Besides, do not pick a topic that cannot be investigated right now due to the lack of knowledge because engineering is not a fiction and requires a proven scientific background. The next step after the topic is known is to organize the future essay. Furthermore, an engineering essay has a crucial factor that differs it from other disciplines in various fields of investigation. The most fundamental part of engineering is the combination of the theoretical framework and practical appliances that play a critical role in the overall perception of the science. Thus, you should keep in mind the cooperation of both mentioned factors by providing the functional background of the issue is essential. One way to give credibility to the previous statement is to implement charts, formulas, and other specific features of the practical application. Finally, every academic writer should remember to use only credible sources of information and literature. Writing an Essay on Engineering as Required by Your Instructor After considering the audience, purpose, and topics of the paper, it is useful to start with the general outline of an essay. Ignoring this stage of writing is an unforgiving mistake that many fledgling writers do because of the lack of skills or experience. Taking this step, you should determine the crucial features of your engineering essay that can help to guide a potential reader through the argumentation of the paper. First of all, it is essential to establish a thesis statement as the central idea of essay writing that should be a core concept of the whole paper. Secondly, after deciding what statement is fundamental, you should establish some supporting points. Thirdly, research the credible sources that may assist in making your essay trustworthy. Also, outlining includes the approximate structure of how your essay will look. As an example of an appropriate way to state a topic, argument and support some main points, you are offered to follow one of the mentioned topics: â€Å"The Management of Engineering Projects†. Its central argument is: â€Å"The management of engineering projects is a complex mission that requires thorough consideration of all possible consequences and comprehensive knowledge of the field.† The supporting point is: â€Å"To make the management of engineering projects successful, it is better to describe every stage of the project in detail for a better understanding of the main notions. Besides, it is essential to point out some possible variants of what can go wrong during an engineering project.† As opposed to a good way to develop an essay, it is worth to find out what is a poor instance of essay writing. Let’s consider it based on the same topic example: â€Å"The Management of Engineering Projects†. It is inappropriate to state that â€Å"Engineering project management is a complex task.† Besides, the supporting point as follows: â€Å"It is important to manage engineering projects successfully.† won’t enhance your essay at all. So an outline of your writing plan for engineering essays should look like the following one: Determine the audience and purpose of essay writing; Decide on an essay topic; Research some reliable sources of information; Develop the main arguments and supporting points; Start writing an essay according to the basic structure; Use the sources with the proper citations and references; Proofread and edit. The Basic Structure of an Engineering Essay Previously, it was mentioned that an engineering essay differs from the other sciences and study areas due to the combination of the necessary theoretical and practical knowledge. Taking into consideration that this is an essay and not a research project or a term paper, your engineering essay should pursue the standard structure with common points such as introduction, thesis statement, body, and conclusion. However, one aspect that can stand as the substantial difference between an engineering essay and, for example, a literature essay is the use of charts or other forms of explanation of the practical appliances of engineering concepts and ideas. Also, the presence of tables changes the whole structure of an essay, but it is easy to handle this factor. If you want to include some charts in the composition, it can be done right after the characterized concepts or after the reference page in appendices that is one of the most general ways. The Introduction That Involves a Reader in Further Reading One way to interest the audience with the introduction is to use the practice of attention-getters that are the controversial or debatable positions that simultaneously involve a reader in further reading. Further, remember that the introduction is the front of your writing, and the proper establishment of the engineering issue helps to convey a point and possibly encourage further discussion or research after concluding the paper. Finally, it should be short and provide a quick guide through the topic. In fact, the primary argument, some keywords, and the thesis statement are the fundamental aspects of the introductory paragraph that starts the cooperation with an audience. However, it is possible to discourage a reader from further reading starting from the introduction of the essay. The easiest way to do it is to write the vague concepts that have no actual attachment to the topic or the argument. Also, remember not to write general ideas that are repetitive, and can be traced in almost every engineering essay such as the importance of this area or not-existing links to the non-technological sciences, for instance, history, management, leadership, human resources, and other. Do not forget that engineering is a precise field of study and includes theoretical and practical frameworks. The Thesis Statement That Is the Core of Your Essay A thesis is the last sentence of the introduction that presents the primary argument to the reader. It is the core of the whole essay, the central idea that guides a reader through your flow of thoughts in an essay, which stands as the statement that needs to be proven in the next essay parts. In fact, the proper thesis statement should be a narrow and a debatable one with the hint of the theoretical and practical appliance after the conclusion. It is possible to construct thesis statements poorly, and the following examples show how it should not be done: â€Å"Engineering can help with the reduction of pollution in the world† It isn’t known in what way engineering helps to deal with the polluted environment in the world; â€Å"Without civil engineering, cities would be impossible† It isn’t stated in what way it makes cities impossible to exist; â€Å"Engineering made significant achievement in all aspects of everyday life† There is no example of significant achievements or aspects in everyday life in which engineering plays a great role. Besides all the weaknesses of the examples above, they are too general and not intriguing. They put the reader in confusion whether it is worth to continue reading the text as these instances sound similar to well-known ideas as well. Moreover, the audience should not agree with your thesis statement simultaneously after reading it for the first time. As a rule, any thesis statement should be proven later as the result of extensive research of credible information sources. But all the main ideas of your essay should be shown in your thesis statement. Follow some examples for the better understanding of the essence of the thesis statements: Pollution is one of the most pressing challenges of the modern society, but chemical and electrical engineering are capable of improving the situation with the help of the new advancement such as electric vehicles and material for the factories. Civil engineering defined the modern notion of cities with the advancement of bridge-building, new technologies for skyscrapers, and the development of sewers and waste disposal strategies. Instead of focusing on the achievement of engineering for the various aspects of everyday life, it is crucial to focus the attention of the public on its’ hazards that can happen in the future. The Body Paragraphs That Move Smoothly The body part of your essay should develop the thesis statement established in the introduction with the help of consequential supporting points. Also, this part should be logical with the smooth transition and proper development of the core ideas you’re going to express in each paragraph. Remember about the significance of using a topic sentence that is the first lines of each paragraph. It is done with the aim to determine the sub-point(s) of each particular main point. Finally, be precise when describing the core concept and brief along with keeping the strict engineering vocabulary. The Conclusion That Is Logical to Complete Your Essay The last paragraph finishes the debate regarding the credibility of the thesis statement and summarizes the whole work. For that reason, you should restate the thesis statement to remind from what that all starts and the main points of the essay described briefly. Do not implement something new into conclusion because it is only a summary that should be logical enough so that no questions will enter the reader’s mind. Some Additional Aspects of the Engineering Essay Writing from Our Experts Remember about the logical flow of writing that eases the task for a potential reader to guess what this essay is about. Don’t forget to use some transitional words assisting to achieve the desired logic of the paper. Don’t end the paragraph with the citations. Moreover, don’t include any citation in the introduction and conclusion of your essay. Address the overall readability of essay content by making the sections no more than two hundred words. In other words, it should have a minimum of three sentences or four lines. The Use of Correct Sources for Academic Writing Besides your own original essay ideas, you need to rely on other relevant information. The use of credible sources is essential to support the arguments in the academic paper. Due to the fact that engineering is a broad science, the amount of credible pieces of research and studies that can assist you in writing is extensive as well. The following databases are helpful while constructing an engineering essay and maintaining academic integrity: Microsoft Academic; Google Scholar; Science Direct; Taylor and Francis Online, etc. Referencing Is a Key Success Factor For an engineering essay, you may use such formatting styles as MLA or APA with the following referencing forms: MLA Author’s Name. Publication Name. Publication Information (edition, volume, issue, publisher). Year of publication. APA Author’s Name. (Date). Publication Name. The source of the Publication. Publication Information (edition, volume, issue). When it was retrieved. Link. Proofreading and Editing Are Final Touches to Your Essay Writing For the final stage of essay writing, you may use all the available variants for proofreading and editing. Either way, don’t ignore it. You can read the written paper several times or offer it to someone for the feedback and fresh perspective. Besides, various web resources available on the Internet can help with spelling and grammatical checking along with checking for plagiarism. Eventually, after using some online resources, don’t be lazy to recheck your essay. But it is advisable to do it after some time after finishing a paper. As a result, your engineering masterpiece is ready for the final submission.

Performance & Reward system- Ericsson company - Case Study Example r hand, reward management is concerned with identifying the motivating aspects of employees which leads to the classification of the amount of pay, compensation and other incentives (Chiang and Birtch 2005). The purpose of the literature review is to help in understanding performance management. The paper presents a case study of past experience attained from the Ericsson Company, Saudi Arabia Branch. The paper is a critique of the performance and reward system in the organization, which highlights the strengths and weaknesses of performance and reward system in the company. It also offers brief information about the company and its branch in the Kingdom of Saudi Arabia, the positive and negative aspects of the company’s performance and reward system, their positive and negative impacts on employee satisfaction, and finally an analysis of the effectiveness of system as well as recommendations regarding how the organization’s performance and reward system can be changed in order for it to allow the accomplishment of organizational goals. However, the report has a limitation in the sense that the experience in this company was acquired 2 years ago, and its performance and reward system might have changed with time. The paper was prepared from information obtained through observations while working in the company, and interactions with employees, as well as the company magazine as well as journals on performance and reward management. Ericsson is a Swedish multinational company that operates through foreign subsidiaries globally. It offers communication systems and services, which include a variety of technologies such as mobile networks and equipments. It also provides fixed network services world wide. These are mainly provided through foreign subsidiaries. Its subsidiary in Saudi Arabia was established in 1980. It operates in through three branches of the Saudi Ericsson, with 360 employees who are professionals in communication technology and other fields of

Philosophy essay Example | Topics and Well Written Essays - 1000 words

Philosophy - Essay Example For instance, in the case of drug possession, long prison sentences are justified by deterrence theory to the extent that such sentences actually do prevent people from using drugs who otherwise would not use those drugs. That last part is important because deterrence is undermined unless it prevents what would happen if the deterrence was not implemented. Deterrence is, by definition, the removal of a cause to prevent an effect. So, considering these long prison sentences for drug possession, it is certainly possible some people are deterred simply because of the potential cost of being caught with illegal substances. In most cases, however, when someone refuses to take illegal drugs, it is not because they were deterred by drug laws and long prison sentences. Rather, it is because of other reasons not related to being caught. Being caught is not necessarily a big concern for most users of illegal drugs anyway. Therefore, it seems it is once again up to the utilitarian to decide whe ther US drug laws and long prison sentences are justified by their effects (the results of strict controls on drugs) in reality. 2. John Rawls’ so-called end-state (or distributive justice) theory of justice stands in contrast to Robert Nozick’s entitlement (or process) theory of justice. The former proposes that all persons in the â€Å"original position† (the state of nature) should agree that all social primary goods, like opportunity and income, are to be distributed equally unless an unequal distribution of any or all these goods is to the advantage of the least favored. For Rawls and the end-state theory, justice is â€Å"fairness†, especially when the proposed redistribution would improve social inequality. Nozick’s entitlement theory proposes that a distribution is just if it comes about by ethical acquisition from the state of nature or through fair allocation.

Effect of the Inorganic Filler Contents on Polymer

Effect of the Inorganic Filler Contents on Polymer ANALYSIS OF ZIF 8/PAI AND CMS/PAI MEMBRANES FOR CO2/CH4 GAS SEPARATION Yohannan Subin Sabilon Department of Chemical Engineering, National Institute of Technology Tiruchirappalli, India Zeolitic Imidazolate Frameworks 8 (ZIF 8) nanocrystals and Carbon Molecular Sieves (CMS) particles were prepared by using standard procedures. UV visible spectroscopy and XRD tests were done for the confirmation of the particles prepared and scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) analysis were done to study the morphology of the particles prepared. ZIF 8/PAI and CMS/PAI MMMs were successfully synthesized by using ZIF 8 and CMS inorganic fillers and Polyamideimide (PAI) polymer using phase inversion technique. Various weight contents (1%, 2% and 3%) of the inorganic fillers were incorporated in the polymer matrix. Reinforcing of the polymer matrix with inorganic fillers was done in the form of nano and micro particles respectively. The effect of the inorganic filler contents on the mechanical properties of the polymer was investigated. Hydrophilic nature and porosity determination test, Fourier transform infrared spectroscopy (F TIR) and SEM were done to study the hydrophilicity and morphology of the composite system. Keywords: Carbon dioxide, Methane, Mixed Matrix Membranes, Carbon Molecular Sieves,Zeolitic Imidazolate Frameworks INTRODUCTION Carbon dioxide (CO2) is one of the components of landfill gas, natural gas and biogas. It is also the main combustion product of fossil fuels and a leading contributor to global warming as its a greenhouse gas. In order to obtain fuel with enhanced energy content, to prevent corrosion problems in the gas transportation system and to reduce the climatic impact of CO2 gas it is quite essential to remove CO2 from those gas streams. This has driven the development of different technologies for CO2 gas separation. Among the different types of technologies being used membrane technology has experienced substantial growth, breakthroughs and advances during past decades [10]. Membrane technology offers high energy efficiency, simplicity in design and construction of membrane modules and environment compatibility. Although there are different types of membranes being used the combination of the superior performance of inorganic materials with the handling properties of the polymers is offered by Mixed Matrix Membranes (MMMs). Therefore in our study we will be using MMMs for CO2/CH4 gas separation. In the MMMs the inorganic fillers are added to the polymer matrix. Over the years different inorganic fillers have been used for preparing MMMs for CO2/CH4 gas separation out of which Zeolitic Imidazolate Framework 8 (ZIF 8) is known to show maximum selectivity while Carbon Molecular Sieves (CMS) is known to show maximum permeability [19]. In this study the preparation and characterization of these inorganic fillers is shown. These inorganic fillers were successfully incorporated in the Polyamideimide (PAI) polymer matrix and MMMs were prepared. The characterization and analysis of the ZIF 8/PAI and CMS/PAI MMMs have been done with different loading of inorganic fillers in order to choose the best possible membrane combination for CO2/CH4 gas separation. EXPERIMENTAL SECTION Materials Zinc hydrate crystals and N-methyl 2-pyrrolidone (NMP) required in the preparation of ZIF 8 nanocrystals were purchased from Merck Life Science Private Limited, Mumbai, India.

Acetone was purchased from Merck Specialities Private Limited, Mumbai, India. All reagents were used without any further purification. Synthesis of ZIF 8 nanocrystals ZIF 8 nanoparticles were synthesized based on the procedure reported by Cravillon et al[3]. The ZIF-8 nanocrystals so formed was sent for UV spectroscopy, XRD, HRTEM and SEM analysis. Synthesis of CMS particles CMS particles were synthesized based on the procedure reported by De. Q. Vu et al[8] The CMS particles were then sent for XRD analysis. Synthesis of ZIF 8/PAI membranes Membranes of 3 different concentrations i.e., 1%, 2% and 3% of ZIF 8 nanocrystals were prepared by solution casting method. 17wt% of polyamideimide polymer solution was prepared by dissolving exactly 5.274g mixture of polyamideimide polymer i.e., Torlon and ZIF 8 nanocrystals in 25ml of NMP solvent in a beaker. A magnetic bead was cleaned and dried using acetone and was placed in the beaker. The 3 beakers containing the 3 different concentration solutions were kept on 3 different magnetic stirrer for complete dissolution. The exact amount of polymer and inorganic filler taken for respective concentrations is given in the table below: Table 1 Composition of ZIF 8/PAI membranes Concentration of ZIF 8/PAI Amount of PAI (g) Amount of ZIF 8 membranes (wt %) nanocrystals (g) 1 5.116 0.158 2 5.169 0.105 3 5.221 0.053 Now 3 glass plates and casting rods were washed and kept for drying. After drying the glass plates and the casting rods were cleaned and dried by using acetone. After complete dissolution the polymer solution in the 3 beakers were casted on 3 different glass plates using casting rods of 750 ÂÂ µm thickness. The glass plates after casting were allowed to dry at room temperature overnight for all the NMP solvent to evaporate. After drying the polymer membrane so formed was peeled off the glass plate. The membrane samples were sent for SEM analysis. Synthesis of CMS/PAI membranes Membranes of 3 different concentrations i.e., 1%, 2% and 3% of CMS particles were prepared by solution casting method. 17wt% of polyamideimide polymer solution was prepared by dissolving exactly 5.274g mixture of polyamideimide polymer i.e., Torlon and CMS particles in 25ml of NMP solvent in a beaker. The exact amount of polymer and inorganic filler taken for respective concentrations is given in the table below: Table 2 Composition of CMS/PAI membranes Concentration of ZIF 8/PAI Amount of PAI (g) Amount of CMS particles membranes (wt %) (g) 1 5.116 0.158 2 5.169 0.105 3 5.221 0.053 A magnetic bead was cleaned and dried using acetone and was placed in the beaker.

After complete dissolution the polymer solution in the 3 beakers were casted on 3 different glass plates using casting rods of 750 ÂÂ µm thickness. The glass plates after casting were allowed to dry at room temperature overnight for all the NMP solvent to evaporate. After drying the polymer membrane so formed was peeled off the glass plate. The membrane samples were sent for SEM analysis. TESTING AND CHARACTERIZATION Confirmation tests for inorganic filers UV visible spectroscopy analysis. The ultraviolet-visible spectroscopy (UV-Vis)utilizes light to determine the absorbance or transmission of a chemical species in either solid or aqueous state. The UV Visible Spectroscopy analysis was done for the confirmation of ZIF 8 nanocrystals. XRD analysis. XRD can be done on a number of different kinds of samples. Smallvolume of sample was tapped on microscope slide glass. The intensity of the beam used was 40 kV and 40 mA. The XRD analysis was done for the confirmation of ZIF 8 nanocrystals and CMS particles. Morphological studies of Inorganic fillers and MMMs SEM with EDX analysis. The surface morphology of PAI polymer was observed usingthe JSM-6701F with high resolution field-emission scanning electron microscopy (FE-SEM) with the magnification of 5000ÃÆ'-. For EDX analysis the acceleration voltage was set to 20kV and the working distance was set to 14mm. The detector was moved down to 45mm. The sample was scanned by X-rays for a time of 200s. The elemental analysis of film in order to confirm the presence of carbon was done using an energy dispersive X-ray spectrometer (EDX) with magnification of 3000ÃÆ'- and acceleration voltage of 15 kV. After the scan was completed the spectrum was plotted using the data obtained from the scan. SEM with EDX was done for the confirmation of the CMS polymer film. TEM analysis. The sample preparation was done by sputtering the same with gold.Then the chamber door was opened and the sample was placed in the sample holder. The chamber door was closed and the required input like voltage, acceleration and time for scan were given to the system connected to the TEM analyzer.

Fourier transform infrared spectroscopy (FTIR) is a technique whichis used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high spectral resolution data over a wide spectral range. Sulfonic acid group functionality of membrane was studied using attenuated -total-reflectance Fourier transform infrared (ATR-FTIR) spectroscopy (Thermo scientific Nicolet iS5 FTIR spectrometer). The spectra for all dried membranes were observed from the range from 4000 to 400 cm-1 wavelength. Mechanical strength test The material strength of the membranes prepared were studied by the performing Stress-Strain tests. The Universal Testing Machine was used to perform the tests. The samples of the membranes were cut into dimensions of height 30mm, width 10mm and thickness 0.45mm. The initial gauge length was set at 20mm. The samples were placed in a sample holder one at a time and the tests were performed. The data was recorded and the graphs were plotted for respective samples. Hydrophilic nature and Porosity determination test The hydrophilic or hydrophobic nature of the membranes were studied by immersing a 1cmx1cm membrane samples in different beakers each containing 20ml water. The beakers were kept on a rotary shaker for continuous mixing overnight. After 24 hours the membrane samples were taken out and the weight of the wet membranes were measured using a digital weighing balance. After that the membranes samples were dried in a vacuum oven at 60oC for 6 hours and then the weight of the dry membranes were measured similarly. The amount of water absorbed and the average porosity of the membranes were determined and the results were tabulated. RESULTS AND DISCUSSION Confirmation of ZIF 8 Nanocrystals The UV Visible Spectroscopy analysis was done for the primary confirmation of ZIF 8 nanocrystals.

Therefore we can confirm that its ZIF 8 nanocrystals. The XRD analysis was done for the secondary confirmation of ZIF 8 nanocrystals. Figure 2 XRD result of ZIF 8 nanocrystals When n-butylamine is added as the modulating ligand, nearly instantaneous formation of a solid is observed upon combining the component solutions, and pure-phase ZIF-8 nanocrystals are recovered after 24 h (see XRD pattern in Figure 2). An average size of 18 nm is estimated from the broadening of the Bragg reflections. The XRD results were also in accordance with the reference paper Cravillon et aL, (2011). Hence we can confirm that the particles synthesized were ZIF 8 nanocrystals. Morphology of ZIF 8 Nanocrystals ZIF materials constitute a new distinctive, rapidly developing subclass of crystalline porous coordination polymers (PCPs) or metal organic frameworks (MOFs). The tetrahedral framework structures of ZIFs are constructed from bivalent metal cations and bridging substituted imidazolate anions and frequently possess a zeolite topology. Numerous ZIFs combine the attractive features of MOFs (diversity of framework structures and pore systems, large surface areas, post-synthetically modifiable organic bridging ligands) with high thermal and chemical stability. Figure 3 SEM image of ZIF 8 nanocrystals It is this combination of properties which makes ZIFs very promising candidate materials for many technological applications. Properties and performance of porous materials rely much on their supply as nano and microcrystals of well-defined size and shape, as is well-known for zeolites. SEM images (Figure 3) reveal that the well-defined nanocrystals have a rhombic dodecahedral shape crystal structure. Figure 4 TEM image of ZIF 8 nanocrystals TEM images (Figure 4) show roughly spherical particles being Confirmation of CMS Particles It is not possible to directly measure permeation properties of CMS particles as with CMS films, replicate mixed matrix films prepared with the two different sieves give very similar effective mixed matrix film permeation properties using powder-pyrolyzed sieves versus the film-pyrolyzed sieves. XRD was performed on the CMS films and powder, as shown in Fig. 5. The XRD diffractograms show very similar peaks and d-spacings, suggesting similar planar dimensions between the film-pyrolyzed CMS and the powder-pyrolyzed CMS, thereby confirming that the particles produced were CMS particles. CMS particles Polymer film Figure 5 XRD results of CMS particles and CMS polymer film Surface Morphology of CMS Polymer Film The CMS membrane films have an intrinsic CO2/CH4 selectivity of 200 with a CO2 permeability of 44 Barrers at 35oC. For UltemÂÂ ®-CMS mixed matrix membrane films, pure gas permeation tests show enhancements by as much as 40% in CO2/CH4 selectivity over the intrinsic CO2/CH4 selectivity of the pure UltemÂÂ ® polymer matrix. Likewise, for MatrimidÂÂ ®- CMS mixed matrix films, enhancements by as much as 45% in CO2/CH4 selectivity were observed. Effective permeabilities of the fast-gas penetrants (O2 and CO2) through the mixed matrix membranes were also significantly enhanced over the intrinsic permeabilities of the UltemÂÂ ® and MatrimidÂÂ ® polymer matrices. These encouraging selectivity and permeability enhancements confirm that mixed matrix membrane behaviour is achievable with CMS particles. Figure 6 SEM image of CMS polymer film Fig. 6 shows top surface SEM micrographs of a CMS polymer film. These micrographs show a smooth surface without any defects. Figure 7 EDX result of CMS polymer film The table below shows the EDX analysis of the CMS polymer film. The sharp Silicon peak is present due to the Silicon detector used during the EDX analysis.

Cross Sectional Morphology of CMS/PAI Membranes Scanning electron micrographs of the CMS fibers are shown in figures 8, 9 and 10 Figure 4.8 SEM image of 1% CMS/PAI membrane Although asymmetry appeared to be present in the CMS fiber morphology, the thicknesses of the layers were markedly different from each other and from those of the precursor fibers (compare with those of the precursor fibers in Figure 6). The original polymeric precursor fibers consisted of a very thin dense skin (1000-2000 Ã…) on a porous core. This skin layer in polymeric fibers has been observed at very high resolution under SEM. In figure 8, high magnification of the wall in the cross section of the PAI CMS fiber reveals a gradual transition from the porous inner core to the denser outer micropore structure. In contrast, high magnification of the PAI CMS fiber shows a uniform dense micropore structure in figure 9. Figure 9 SEM image of 2% CMS/PAI membrane Figures 8, 9 and 10 show SEM micrographs of a mixed matrix film after these modifications. These micrographs demonstrate smaller CMS particles (mostly Figure 10 SEM image of 3% CMS/PAI membrane Cross Sectional Morphology of ZIF 8/PAI Membranes Figures 11, 12 and 13 shows SEM images of ZIF-8/PAI mixed matrix dense films, which indicates good contact of bare ZIF-8 to the PAI matrix without sieve-in-a-cage morphology at each loading. It is noteworthy that the good contact was achieved without any surface treatment of the sieve. This should be due to the hydrophobic nature of ZIF-8, proved by TGA measurements in reference paper Zhang et. al. (2012). Interestingly, in the SEM images of ZIF-8/PAI mixed matrix dense films, as shown in figures 11, 12 and 13, we observe a morphology that has not been previously reported in mixed matrix membranes prepared with other molecular sieves. Other than well-dispersed 10 nm ZIF-8 particles, there also exist many non-ideal large clusters of ZIF-8 with size ranging from 50 nm to several microns, which is more than an order of magnitude larger than single ZIF-8 particles. Also, volume fraction of large ZIF-8 clusters in the matrix increases with increasing ZIF-8 loading. Figure 11 SEM image of 1% ZIF 8/PAI membrane Unlike agglomerations of molecular sieve particles that have been previously reported in mixed matrix membranes prepared with other molecular sieves, the surface of these large ZIF-8 clusters as revealed in figures 11, 12 and 13 looks fairly smooth. Also, almost no defects were observed for these clusters among all the ZIF-8/PAI dense film samples. Since film samples were randomly fractured for SEM analysis, we believe that the mostly non-defective feature of these large ZIF-8 clusters shown in figures 11, 12 and 13 is representative of their interior structures. It is important to understand the formation mechanism of these large ZIF-8 clusters and their impacts on gas transport properties of the mixed matrix membrane to allow extension to practical asymmetric structures. By achieving the desired uniform distribution of individual ZIF-8 particles with the PAI matrix we can achieve outstanding gas separation results. Figure 12 SEM image of 2% ZIF 8/PAI membrane Figure 13 SEM image of 3% ZIF 8/PAI membrane The cross sectional view of the ZIF 8/PAI membranes shows good adhesion between the inorganic filler ZIF 8 and the polymeric membrane PAI. The figures show the SEM images of 1%, 2% and 3% ZIF 8/PAI membranes prepared respectively.
