Carbon Nanotubes Uses and Properties

Carbon Nanotubes Uses and Properties ABSTRACT: For the first time in the human history, we are close to being able to manipulate the basic forms of all the things, living and inanimate, take them apart and put them together in almost anyway the mind can imagine. The sophistication with which scientists are learning to engineer matter at the nanometer scale is giving us unprecedented mastery of a large part of our environment. The world of the future will be defined by how we use this mastery. Nanotechnology is engineering at the molecular (groups of atoms) level. It is the collective term for a range of technologies, techniques and processes that involve the manipulation of matter at the smallest scale(from 1 to 100 nm2). Carbon nanotubes have been under scientific investigation for more than fifteen years because of their unique properties that predestine them for many potential applications. The field of nanotechnology and nanoscience push their investigation forward to produce carbon nanotubes with suitable parameters for future applications. Carbon nanotubes are one of the most commonly mentioned building blocks of nanotechnology. With one hundred times the tensile strength of steel, thermal conductivity better than all but the purest diamond and electrical conductivity similar to copper, but with the ability to carry much higher currents, they seem to be a wonder material. Field effect transistors using carbon nanotubes came into existence, these have a extremely good properties. CARBON NANOTUBES: Evolution of Nano Importance of Nano in present day scenario Moores Law Greatness of Carbon Graphene Carbon nanotube Synthesis of CNT Properties of CNT Purification methods Real time applications GREATNESS OF CARBON: Carbon is the 4th most abundant element in the Universe by mass after( Hydrogen, Helium and Oxygen). Forms more compounds that any other element, with almost 10 million pure organic compounds. Abundance, unique diversity and unusual polymer forming ability at the temperatures makes the element the chemical basis of life. CARBON NANOTUBES: Carbon nanotubes are long, thin cylinders of carbon which were discovered in 1991 by Sumio Iijima. A sheet of graphene rolled in cylindrical structure results in Carbon nanotube of 1 atom thickness and diameter in nano scale. Nanotubes have a very broad range of electronic, thermal, and structural properties that changes due to change in length, diameter and chirality or twist. Types of Carbon Nano Tubes: Single walled: In these single walled nano tubes are narrower than the multi walled nano tubes ,the diameters typically in the range of 1-2nm ,and tend to be curved rather than straight. In these SWNT only single layer of grephene .Catalyst is required for synthesis .Bulk synthesis is difficult as it requires proper control over growth and atmospheric condition .In these SWNT Purity is poor and less accumulation in body .Characterization and evaluation is easy .It can be easily twisted and are more pliable. These tubes are used to make super strong amour bodies .These single walled nano tubes are used as elastic property and used to make bullet proof vests. Multi walled: Multi walled nano tubes consists of multiple layers of graphite rolled in on themselves to for a tube shape .There are two models which can be used to describe the structures of multi walled nano tubes .In these MWNT multiple layer of grephene and can be produced without catalyst Bulk synthesis is easy .Purity is high ,more accumulation in body .It has very complex structure .It can not be easily twisted. Synthesis: Laser ablation: A pulsed or continuous laser is used which will vaporize a graphite target in an oven at 1200c . Oven is filled with helium argon gas .In order to keep the pressure at 500 torr ,Since the optimum background gas as catalyst mixture is the same as in the arc discharge process Laser ablation method is similar to arc discharge method .This method is vey expensive so it is mainly used for SWNT’s laser vapourization results in higher yield of SWNT’s with narrow size distribution than those produced in arc discharge process .Catalyst used for SWNT is NI:Y (4.2:1 At%). Arc Discharge Method: Arc Discharge method has been reported for producing carbon nano tubes .In these method nano tubes are produced through arc vapourization of two carbon rods placed end to end with a distance of 1mm in an environment of inert gases such as helium argon at pressure b/w 50 to 100 amps driven by 20v which will create high temperature discharge b/w two electrodes ,due to this anode wil get evaporated and rod shaped tubes will be deposited on cathode.Bulk production of CNT’s depends on uniformity of plasma arc and temperature of depositon The Main principle is carbon nano fibres are good at absorbing energy so they can absorb the energy coming from the bullet .The inherent property of elasticity makes the bullet to rebound .Its is 100% stronger thean steel.Lighter than aluminium.Conduct electricity as copper .These fibres can be used as space elevators . Purification Of CNT’s: Nanotubes usually contain a large amount of impurities such as metal particles ,amorphous carbon ,and multishell .These are different steps in purification of nano tubes . Air Oxidation: The Carbon nano tubes are having less purity ,the average purity is about 5-10%.So,Purification is needed before attachment of drugs onto CNT’s .Air oxidation is useful in Reducing the amount of amorphous carbon and metal catalyst particles (Ni,Y). Acid Reflexing: Refluxing the sample in strong acid is effective in reducing the amount of metal particles and amorphous carbon ,different acids used were hydrochloric acid (HCL),nitric acid(HNO3)and sulphuric acid (H2so4)bt HCL is identified to e ideal reflexing acid . Surfactant aided sonication, filtration and annealing: After the acid reflexing ,the CNT’s were purer but ,tubes were entagled together ,trapping most of the impurities,such as carbon particles and catalyst particles ,which were difficult to remove with flitration .so,surfactant –aided sonication was carried out .sodium dodecyl benezene sulphonate (SDBS) aided sonication with ethanol or methanol ,as organic solvent were preferred cz it took the longest ime time fr CNTS to settle down ,indicating an even suspension state was achieved .The sample was then filtered with un ultra filtration unit and annealed at 1273k in N2 for 4H .Annealing is effective in optimizing the CNT structures .It was provided the surfactant –aided sonication is effective to untangle CNT’s thus to free the particulate impurities embedded in the entanglement .Nano tube can also be purified by multistep purification method . Real time applications: Carrier for drug delivery: Carbon Horns (CNHs) are the speherical aggregates of CNT’s with irregular Horn like shape .Research studies have proved CNT’s CNH’s as a potential carrier for drug delivery system . Genetic Engineering: In Genetic engineering ,CNT’s and CNH’s are used to manipulate genes and atoms in the development of bio imaging geneomas protemics and tissue engineering .The unwound DNA (single stranded )winds around SWNT by connecting its specific neucletoids and causes change in its electrostatic property .this creates its potential application diagnostics and in therapeutics Nano tubes and nanohorn’s can adehere various antigens on their surface ,hence act as source of antigen in vaccines .Hence by use of nanotubes ,use of dead bacteria as source for antigen which is sometimes dangerous can be avoided . Pseudo spark switches: These are switches which work upon principle of field emission, this emission is achieved by triggering. Generally the triggering methods are Surface discharge triggering Optical triggering Pulsed low-current glow discharge triggering But cnt’s have a good emitting properties when compared from above methods. For field emission cnt’s are used as cold cathode emitters. The field emission characteristics of cnt’s are mostly reported at high vacuum pressures of 10^-6 and 10^-7 torr. Usage of cnt’s for field emission resulted in good properties and working of pseudo spark switches in both high pressure and low pressure vacuum..

The Theatre and its Identity Crisis Essay -- Female Roles in Theatre

My trust in the definitiveness of reality is swiftly disintegrating beneath me. The deeper I dive into the abyss of theory, the more I realize that nothing I have learned is safe from change; that facts may actually be temporary and that everything is a prisoner of our construction of time. In admitting this, I worry that these hypotheses are the beginning of a tiny delusion that will begin to gradually eat away at the rest of my sanity. That scares me a bit, yes, but even as I sit here writing, I love this newfound instability because it’s ironically made me feel more grounded than I’ve ever felt. Armed with these ideas, I have looked back at the world I’ve grown up with and finally begun to see society’s seams tugged apart, its splintered frame exposed, and the fear and worry of its people uncovered. But I have also exposed, buried deep within its guarded chest, the hope and innovation and change that inspires humanity’s pervasive drive towards pr ogress. It’s within this fragmented existence that I feel that I have a place within this generation’s script. However, it’s now a matter of figuring out which role is mine. The cynic inside me can’t help but look at the cast list and feel an irrepressible sense of sadness; with such a long list of characters to choose from, why do we prescribe such commonplace roles to ourselves? I believe that it all starts with gender. Judith Butler reasons in her inspirational essay â€Å"Performative Acts and Gender Constitution: An Essay in Phenomenology and Feminist Theory† that gender is a performance. She observes that sex (the biological facts defining male and female) is not what actually makes a man and man and a woman a woman, but rather that one’s gender identity is determined through a styliz... ...easy for the less informed to drown in if one detail is highlighted with greater weight. It’s been a constant power struggle between these two genders whose desperate goal is to find some sort of order amidst chaos. It’s simply easier to have a leader, but the ways in which we’ve selected these privileged few I find disquieting. Though I do not believe that gender is one hundred percent learnt, as Butler believes, I do think that societal impositions play too strong a role in creating identities. This is especially true in the theatre, and I know that many of my female classmates will agree with this. Women are capable of acting in masculine manners just as the converse is true for men. But if this idea is to ever branch out into the real world, whatever that may mean, the theatre is a perfect place for its journey to begin- and I believe that has every right to.

Cra and Financial Crisis

Table of Content Introduction2 Real-life examples2 Empirical cycle2 Other concepts of Babbie, Gravetter and Forzano applied2 Conclusion2 References2 Introduction The burst of the United States housing market bubble initiated the worldwide financial crisis. Amongst all housing regulations, the community reinvestment act (CRA) may be the most significant. The act passed in 1977 to improve low-income households’ housing opportunities. As such, the act raised the incentives for banks to provide mortgages to low-income households (FFIEC, n. d. ). Over time, several political administrations, like the George H.W. Bush-, Clinton- and George W. Bush-administration, changed the original act, adapting to new challenges in the housing market (Braunstein, 2008). However, as time passed, the act became less important for banks, as the products, mortgages, became more profitable. As a result, more and more financial institutions started offering mortgages to low-income classes. These so cal led subprime mortgages are often associated with high risks (Aalbers, 2009). This point of view can be concluded with the hypothesis that the CRA will be seen as a cause of the financial crisis.Firstly, the different opinions and their respective arguments with regard to the hypothesis are illustrated. Secondly, an explanation is given on how these examples fit in the empirical cycle. Thirdly, three other concepts of Babbie, Gravetter and Forzano are applied to the examples. Finally, a conclusion is drawn with respect to the examples. Real-life examples As a result of the CRA, banks were rated, based on the number of loans given out to low-income households. A bad rating could have had severe consequences for a bank.The fact that the FED did not allow a Hartford, Connecticut bank to acquire a New Hampshire bank on CRA grounds demonstrates this. In order to keep their CRA ratings high, banks had to provide low-income classes with loans. In essence it can be said that the CRA ratings raised the banks’ incentives to provide low-income households with loans (Carney, 2009a). It can clearly be seen that the enforcement of the CRA over time led to a relaxation of lending standards and consequentially to more risk-taking in the banking sector in the form of mortgages. These high-risk mortgages are now seen as part of the problem.Thus, Carney (2009b) concludes, the CRA is part of the cause of the financial crisis. Carney agrees with the hypothesis. Defendants of the CRA simply claim that an act passed in 1977 cannot lead to the creation of a housing bubble in the early 21st century. Nevertheless, the CRA was not a static piece of legislation. The act evolved over the years, as it was mentioned earlier in the introduction. To be more specific, it was more and more enforced over the years. As a conclusion it can be said that the enforcement of the CRA might have been crucial in creating the housing bubble.Therefore the act could have created a housing bubble in th e early 21st century (Carney, 2009a). However, Aalbers (2009) also argues in favor of the CRA and tries to falsify the hypothesis. He states that the majority of subprime loans in 2006 were provided by non-bank lenders. These non-bank lenders, however, were not subject to CRA regulations and thus were not obliged to provide affordable loans to low-income classes. The only logical conclusion that can be drawn from this information is that these loans to low-income classes were an attractive investment.Thus, Aalbers says, the CRA was not the cause of the high-risk mortgages providence to low-income households by banks. By clearly, Aalbers would reject the hypothesis that the CRA was a cause of the financial bubble. Nonetheless, his argumentation has to be questioned. In 1977 most of the loans and mortgages were provided by banks as well as savings and loan associations. The extra mortgages that were provided as a result of the CRA probably increased the demand for houses, which in tur n resulted in an inflation of housing prices.Several years later, due to rising housing prices, subprime mortgages became a more attractive investment for financial institutions. Consequently, the majority of loans issued since the inception of the CRA came from nonbanks that deemed mortgages a good investment. In other words, the CRA created major lending opportunities for financial institutions (Kroszner, 2009). Since the CRA initiated the inflation of housing prices to some extent, it can be argued that the CRA can be hold partly responsible for the creation of the housing bubble. This theory should verify the hypothesis. This argumentation has to be investigated further.As Foote et al. ’s (2008) research concludes, housing price data in Massachusetts reveals that around 70% of all homes lost to foreclosure were actually purchased with prime mortgages. From that information Aalbers (2009) derives that most loans were not used for directly financing new homes, but rather re financing existing loans. Hence, Aalbers insinuates that the extra mortgage lending as a result of the CRA did not cause a rise in housing prices. That information implies that the CRA was not a cause of the creation or inflation of the United States housing bubble. Clearly, this would reject the hypothesis.Nonetheless, Aalbers’ argumentation contains two pitfalls. First, his argumentation solely rests on inductive reasoning. Massachusetts is just one small part of the United States of America. Without any supportive data to back up the thesis that the Massachusetts housing market is representative of the whole nation’s housing market, it has to be concluded that Aalbers overgeneralizes the statistical data provided by Foote et al. As Babbie (2005) mentions, overgeneralization can lead to misdirection or rendering of inquiry. Due to this fact Aalbers’ argumentation is questionable. Second, even if the study of Foote et al. 2008) were representative, Aalbers fail ed to acknowledge the other side of the medal: The supply side, as it is not in favor of his opinion. If the CRA-related loans were used to refinance homes only, it would strongly affect the supply side of the housing market in the way that supply was artificially lowered. Homes were occupied that otherwise would not have been, driving up the prices of real estate. Aalbers falls victim to the fallacy of selective observation. He only looks at the effects of the CRA on the demand-side. Looking at the supply-side would not support his theory and point of view on the topic.That makes this observation a selective one. Empirical cycle This debate fits in the empirical cycle in the way that it started with an observation: The burst of the housing bubble. Consequentially different hypotheses and theories where formulated and tested by reasoning and correlation. As markets nowadays are very complex phenomena, it is difficult to establish a causal relationship between several factors of this system. In spite of that it is possible to use logical reasoning and correlation between these factors to hint at the correctness of a thesis. For example, it can be investigated how many subprime loans were CRA-related.A different question that can be posed is how these CRA-related subprime loans performed against other loans (Kroszner, 2009). The answers to these questions could give an idea of the causal relation between the CRA and the financial crisis. After testing the hypothesis, a new hypothesis and theory might be formulated until a conclusive theory is found. Nevertheless, Kroszner himself admitted the existence of a lack of data to get conclusive answers to the previously mentioned questions. For the empirical cycle, this lack of data means it is very hard to reject or not reject theses, obstructing the formulation of new theses and theories.Other concepts of Babbie, Gravetter and Forzano applied The empirical cycle is not the only concept of Babbie (2005), Gravetter and Forzano (2009) which can be applied to the examples. Another concept that can be applied apart from the empirical cycle is the concept of authority. Carney (2009a), who was mentioned earlier in this paper, started out as a strong defendant of the CRA. He did change his mind though, relying on, among others, the FED Governor Meyer. Since Carney used a quotation of Meyer, it can be concluded that Meyer is a person with authority and strong references in the field of economics.Babbie, Gravetter and Forzano define authority as a person with strong references in certain fields. Authority is used as a source for knowledge and can be referred to. Gravetter and Forzano (2009, p. 11) define rationalism as the search for â€Å"answers by the use of logical reasoning†. This is exactly what Carney (2009b) does to come to the conclusion that the CRA was a cause of the financial crisis. He reasons that the CRA raised the banks’ incentives to provide low-income households with mortg ages. These financial products are now seen as a cause of the housing bubble, which caused the financial crisis.Therefore, Carney concludes, the CRA is a cause of the financial crisis. Theory is described by Babbie (2005, p. 12) â€Å"as a systematic explanation for the observations that relates to a particular aspect of life†. This implies that the argumentations used by Carney (2009a, b), Aalbers (2009) and Kroszner (2009) are parts of different theories as they explain how the CRA caused or did not cause a housing bubble. Conclusion As shown in this paper, there is a huge debate about whether the CRA was a cause of the financial crisis. As Carney (2009b) pointed out, the CRA raised the banks’ incentives to issue risky loans.Critics, however, state that an act passed in 1977 cannot create a housing bubble in the early 21st century. Nevertheless, the act was enforced several times, which implies that an enforcement of the CRA might have a causal relation with the fina ncial crisis. Aalbers (2009) argues also in favor of the CRA: he points out that most subprime mortgages were provided by non-CRA-related institutions. Despite that fact, Kroszner (2009) says there is no reason to believe CRA is not to be blamed. He mentions that the inception of the act increased the demand for mortgages and consequentially, houses.According to Kroszner, this was the start of the housing bubbles. Aalbers on his turn argues that the vast majority of houses bought in Massachusetts was financed with prime mortgages. He concludes that this provides evidence in order for the CRA not be labeled a cause of the crisis. Nonetheless, Aalbers argumentation contains two fallacies. First, he uses inductive reasoning which results in overgeneralization without supportive data. Second, he uses selective observation by ignoring the supply-side of the market. This whole debate fits in the empirical cycle in a way that it started with an observation which was followed by many theses .After the formulation of these theses they were tested by logical reasoning and correlation. As a final step, new theses theories will be formulated. However, this step is obstructed heavily by a lack of data. Other concepts of Babbie (2005), Gravetter and Forzano (2009) can also be applied to the examples. Meyer has authority in Carney’s argumentation, logical reasoning is used by Carney to come to the conclusion that the CRA was a cause of the crisis and the argumentations used by Carney, Aalbers and Kroszner are all parts of theories, described by Babbie, Gravetter and Forzano.References Aalbers, M.

Zero Tolerance essays

Zero Tolerance essays The idea behind zero tolerance policing is that a strong law enforcement approach to minor crime (in particular public order offenses) will prevent more serious crime from occurring and will ultimately lead to falling crime rates. Zero tolerance policies are based on the broken windows theory by Wilson and Kelling. An unrepaired window is a sign that no-one cares and therefore more damage will occur. Zero tolerance policies feel that if disorderly behavior is not dealt with in a particular area, then more serious crime will be the result. Nuisances such as public drunkenness, vandalism, begging and so forth create an atmosphere where more serious crime can occur. The zero tolerance approach was originally introduced by the New York Police Department and Mayor Rudolph Giuliani. Based on the information I have read, it appears that New Yorks crime rate dropped drastically during the period in which there were zero tolerance policies. According to statistics since 1993, major crime in New York City has fallen by 39% and murder has fallen by 73%. Whether it was this approach, or some other factor, which was responsible for the recent falls in crime in New York and elsewhere, I am unsure. One theory for the decreased crime rate is that fewer people are involved in the crack epidemic which swept the city in the 1980s and early 1990s. Another theory is that the majority of the offenders responsible for crime in the 1980s are now in prison. Some of the opponents of the zero tolerance policies state that the police are based on a punishment mentality, which creates fear and distrust in many communities. The most serious complaints about "Zero Tolerance" revolve around police brutality. Other opponent of zero tolerance policies feel that zero-tolerance policing means zero tolerance for certain people mainly black males who are disproportionately arrested and convicted of crimes. ...

Women in Westerns essays

Women in Westerns essays Womens roles in western movies are very diversified. Although the roles are very different from each other, they are very stereotypical. Almost all women characters in western movies play one of the following: a mother, school teacher, prostitute, or an outlaw. Through comparing three western movies, all ranging in different eras from 1932 to 1994, it is clearly shown that whether its the loving mother or town prostitute, women characters often play a minor part compared to the men, yet they are very important to the whole development of the film. Jean Aurther plays a very loving mother and wife in the 1952 film Shane. The opening scene perfectly depicts the stereotypical mother. She stands near a window washing dishes. She is watching her son play outside. A strange man rides up on his horse and begins to talk to the little boy. The woman peers out the window at the hansom mysterious man. As he catches her looking at him she quickly hides her face as if not to be seen. Her husband then comes out to talk to the stranger. The window and her face is always seen in the background as the two men talk but she often hides from the view of the window. Finally she comes outside and stands next to her husband without speaking as her husband introduces the little woman to the stranger. This opening scene depicts the woman as inferior to her husband. She is doing housework in the background and is not heard. She does not speak except for the polite invitation for dinner to the stranger. She then silently leaves the scene to go inside to finish up fixing the dinner. Jean Aurthers character as the typical wife tends to all of the household duties including all of the cooking and cleaning and takes care of the garden. She is always looking after the little boy making sure that he is not getting into any trouble. During the dinner scene the wife does all of the serving at th...

Ethics, Corporate Governance and Social Responsible Investemtn Essay

Ethics, Corporate Governance and Social Responsible Investemtn - Essay Example A number of other major economies have however embraced the adoption of the enabling mode of governance and rejected the mandatory corporate governance. A number of differences exist between these two systems as outlined by Anand, (2005). Mandatory corporate governance is practiced in major states of the United States, a mandatory system provides guarantee that firms in this system will have to implement any reforms that market regulators put in place. This is contrary to the enabling governance where nothing guarantees a fair play and the enforcement of implementation of any changes. Enabling governance has the ability to ensure that there is compliance to regulatory mechanisms especially when it is implemented together with mandatory disclosure of organizations practices. Mandatory system is also slightly more costly to implement when compared to the enabling governance style (Anand, Milne, and purda, 2006). Mandatory corporate governance is majorly practiced in the United States w hile the United Kingdom practices the enabling kind of governance. Canada and Australia are other major countries that also practice the enabling kind of governance apart of the United Kingdom. The United States mandatory governance is however a blend of the two systems. In some states, companies are not compelled to adhere to the requirements but are required to make formal disclosure of the rules they have or have not adhered to. Firms that are cross listed in the United States are required according to the Sarbanes-Oxley act to submit their evidence of compliance to the mandatory governance regulation. The SOX regulation has a prohibition for ‘insider loans’ especially among companies listed under this act. Such companies must also ensure that they submit their balance sheets for each financial year (Anand, 2005). The mandatory corporate governance system of the United States also has a requirement for all companies listed under its stock exchange at the NYSE and NAS DAQ. They are required to include independent directors in the management board of the firms; the same policies are also practiced in Canada. Firms are required to submit their compliance statuses through proxy to the provincial commissions who are also mandated to ensure that there is strict formulation and administration of the guidelines (McCahery and Vermeulen, 2010). Under the enabling system as practiced in the UK, compliance with corporate guidelines is voluntary. Only companies that are listed in the London stock exchange are obligated by law to submit their compliance in their annual reports. The system as practiced in the United Kingdom has been adopted in Australia with a few modifications on the reporting mechanisms. The UK system also applies incentives that are meant to make firms disclose their compliance information; disclosure of information in the enabling system depends on the sensitivity of the information. In situations where firms feel that their competitors ma y benefit from exposure, such firms have the right to withhold their compliance (Anand, 2005). Enabling systems is also known as voluntary governance system, this is majorly because of the free atmosphere that it creates for its firms. Firms in this system can either chose to disclose their information or not to be based on their reasons; this is the system which is practiced in the
