Dr. Roy Plunkett created Polytetrafluoroethylene also known as Teflon in 1938 after receiving his PhD in organic chemistry and took job with DuPont in Jackson, New Jersey. Dr. Roy was appointed to work on finding a non-toxic substitute refrigerant other than ammonia and sulfur dioxide. [1] Teflon was accidently invented when Dr. Roy and his assistant, Jack Rebok, were experimenting with one of the potential refrigerants; tetrafluoroethylene (TFE) and he consequently produced around 100 lbs of gas and stored them in cylinders. Upon opening the valve after few days even though the cylinder was full when weighed nothing was coming out as the gas inside the cylinder was solidified. Dr. Roy and his assistant decided to cut the cylinder into half and once they managed to open the cylinder they discovered that the gas in the cylinder had been converted into a white waxy powder …show more content…
Later by 1960’s it was used in variety of applications like windshield wipers, nonstick utensils, furniture (strain repellent) etc.

Structure and synthesis

Fig 2 Structure of Teflon (CF2CF2) [4]

Teflon (CF2CF2 ) has an amazing property in its structure; it is also a carbon based chain like most of the polymers. Carbon based polymer chains have C-H bonds in common where as in Teflon all the hydrogen bonds are replaced with fluorines, these C-F bonds are extremely strong and tough to attack any other chemicals. This means that no other molecule will react or stick to it except for Teflon itself forming thick layers of solid blocks with coefficient of friction 106 cycles 5-80*103 cycles 10-500*103 cycles 10-27*103 cycles

...be used for the food industry, as well as beauty products, and pesticide, to name a few. Research has shown that phthalates have been connected to things such as cancer, premature birth, asthma, and a host of other medical issues. Being that phthalates aren’t bonded chemically to the plastic, they can easily move on from the plastic. An example of a product that used quite frequently is Teflon cookware. Nonstick cookware is something that most aren’t aware that can have an ill effect on them. When you heat a nonstick pan at a high temperature, the fumes cause something called Teflon flu. This can cause humans to get flu like symptoms. Teflon has been linked to cancer and organ damage (The Effects of Plastic Bags on the Waterways) (Plastics, the environment and human health: current consensus and future trends) (Teflon Flu). 3. One of the ways that I would encourage co-workers to cut back on the solid waste generated is by reducing the amount of paper that is used. The EPA has estimated that approximately 40 percent of the garbage that is generated comes from paper or paperboard. Nationally over 700 trillion tons of paper is used annually in the US, so based on these two factors, this is a good area of reduction to focus on. Some ways to reduce the amount of paper used is to only print something when absolutely necessary. When printing, try and print on both sides of the paper. Use paper that has been printed on one side to print on the other side in the future, store things...

Cancer Industry Corruption

...Have you ever wondered why, despite the billions of dollars spent on cancer research over many decades, and the constant promise of a cure which is forever "just around the corner", cancer continues to increase? Especially when According to the International Agency for Research in Cancer "...80-90 per cent of human cancer is determined environmentally and thus theoretically avoidable." Hi my name is Spenser Grandstaff and today I would like to present some startling information and talk to you about the corruption of the cancer industry and how it affects all of us. A top medical doctor recently came out and said conventional cancer doctors regularly lie about success rates, and the system is designed to steer patients toward the most expensive treatment possible. This wasn’t just any doctor. It was Otis Brawley, head of the American Cancer Society — the very heart of the cancer treatment establishment. He said unproven cancer treatments are in widespread use across the U.S. And he wasn’t’ talking about natural or alternative treatments. He was referring to things like PSA exams and chemotherapy. A colleague of mr brawley was Dr. John Bailer, who spent 20 years on the staff of the U.S. National Cancer Institute and was editor of its journal. He said "My overall assessment is that the national cancer programme must be judged a qualified failure" Dr. Bailer also says: "The five year survival statistics of the American Cancer Society are very misleading. They now count...

This paper involves computational fluid dynamics analysis and simulation of a shock wave generating equipment. Shock waves are produced by suddenly exposing a high pressure region to a low pressure region. This involves in the design of an arrangement that acts as a valve which separates high pressure region and low pressure region such that the valve opens suddenly (i.e., in the order of milliseconds) and thus producing shock waves. The instantaneous rise in pressure and temperature of a medium can be used in a variety of industrial applications Key words: Shock waves, Shock tubes, CFD, Pneumatic Valve 1 Introduction The ability of shock waves to instantaneously increase the pressure and temperature in a medium of propagation enables their use for many novel industrial applications[1]. In some sense the presence of a shockwave propagating in an enclosed medium can be similar to a furnace where, in addition to temperature, even pressure can go up instantaneously and remain at elevated levels for a short time and...

Dupont Case

...Introduction The products include Pioneer and other brands of seeds, insecticides, fungicides, herbicides, insect control products, and plant growth regulators. Acquisition and Selling of Conoco Our recommendation: Our recommendation is based on the performance of the division called Conoco which was the chief operating division adopted by the company in 1980s. As per our recommendation DuPont should divest in Conoco in a phased manner so that company can be free of non performing unit. Between 1940 and 1980, DuPont developed and marketed technologies such as Dacron, Mylar, Lycra, Kevlar, Tyvek, and Nomex. The company also expanded its pharmaceuticals and medical products business. The company acquired Conoco, an energy supplier, in 1981. In 1991, DuPont's pharmaceutical business entered into a joint venture (JV) with Merck, to focus on non-US markets. During the 1990s, the company acquired Protein Technologies International, a producer of soy protein products and Imperial Chemical's polyester-resins, a company with intermediates and polyester-films operations. In 1998, the company bought Merck's share of the pharmaceutical JV and renamed the company, DuPont Pharmaceuticals. Later that year, DuPont started selling its interests in Conoco which was completed in 1999. Conoco facility can be classified as cost center. It is one of the main cost centers of the company and hence the most resources are hogged up at this center. One needs to identify resources properly at this...

Audrey was conceived with a lot of fanfare, much ado and of blue blood. She was well planned and conceived with high hopes. She had everything going for her—looks, money, fame, fortune, power, hype, high expectations and a perfect incubation. A scant six month later, Audrey died. Her parents wanted it to be a quiet affair, but it was not. The death of Audrey sent shock waves through the community. How can such a tragedy happen? In case you did not get to know or love Audrey, she was not human. She was a much-hyped breed of gadget called the Internet Appliance.

Strategy Formulation

...Strategy Formulation Ronald Rogers MGT680-1303A-01: Strategic Management American Intercontinental University Synopsis Often a business, particularly a startup, has little to no choice in when to introduce a product or service. However, given the opportunity, market information, and competition data, managers should be able to make valid choices concerning the release time of that product. This paper addresses the advantages and disadvantages of first move or late move into a market. It also explains how and why companies have succeeded and failed in both theories. Part One: First Mover Theory First Mover Advantages (FMA) FMAs have a unique opportunity to create barriers to competition such as limited resources and patents. They may have a sustainable advantage in technology that is Intellectual Property (IP), R&D, Patents, and resources. They have a monopoly of sorts, however short term that it may be (Lieberman & Montgomery, 1988). Rapid expansion of market share with a new product is extremely likely. Introducing new products involves in-depth market research and a large investment of time and other resources. The results of the market penetration by a first mover can be difficult to overcome for subsequent entries. Setting the benchmark is an advantage that first movers can exploit. If they introduce a product that becomes a high demand item, establish the brand name and provide good service, then they set the bar really high for late entries. Tendency...

Scanning electron microscopy studies indicated that the silver nanowires are about 100 nm in diameter and up to 500 mm in length. High-resolution transmission electron microscopy analyses showed that the Keywords: green chemistry · hydrothermal synthesis · nanostructures · nanowires · silver Introduction One-dimensional nanostructures of metals have attracted much interest due to their potential applications in fabricating nanoscale electronic, optoelectronic, and magnetic devices, which also provide an ideal model system to experimentally investigate physical phenomena, such as quantized conductance and size effects.[1–6] Among all metals, silver nanowires are particularly interesting to fabricate and study because bulk silver exhibits the highest electrical and thermal conductivity among all metals, and the performance of silver in many applications could be potentially enhanced by processing silver into one-dimensional nanostructures. Much effort has been devoted to the syntheses of silver nanowires, such as electrochemical techniques,[7–9] templates (i.e., mesoporous silica[10, 11] and carbon nanotubes[12...

For the purpose of our study, we will measure the impact in terms of association, neutral and disassociation of ingredient brand with host brand. In this study many theories and models is studied to identify the potential factors of ingredient branding. The research methodology adopted for the analysis in our study is to some extent a replica of previous studies conducted within ingredient branding. We conducted a survey based on questionnaire method. For which a close ended structured questionnaire on 5- point Likert scale basis is being designed .The survey was conducted among 212 respondents consisting of customers in Indore city. While doing this research we have gained insights on how several aspects of our study could have been conducted differently. We recommend that a similar study should be conducted again, this time with well known host brands and ingredient brands that focus on utilitarian needs from a consumer perspective. A more representing respondent group would also increase the arguments for generalization among a wider population. By using SPSS we can conclude that the perceived impact of various factors of ingredient brands on host brand and its brand equity. Journal...
