Before the first module of the ISS, Zarya, was sent to space, many chemists and engineers were developing and perfecting materials that the ISS would be made of. Before the idea of an international station in space had arose, the Long Duration Exposure Facility, which was a schoolbus-sized, cylindrical facility designed to test the exposure of different materials in space, was sent to space with Space Shuttle Challenger on mission STS-41-C on April 6th, 1984, providing NASA with materials research data that is still used today (Kinard). The LDEF carried over 10000 materials samples, consisting of virtually any material even remotely considered for future optical, mechanical, electrical and other systems on future spacecraft, but most of the probe was covered in chromic anodized aluminum and silver Teflon thermal blankets (ibid.). The result of the experiment benefits spaceflight materials eng...

- Faced with the potential opportunity to continue my research into space exploration, it is time for me to prove myself worthy of this grant in order to pursue answers to my very real questions. As a superior researcher, I find that I am most deserving of the chance to be funded to travel back in time and see firsthand what the reaction of the public was to the early space missions, among other possible uses of the trip. Your funding of this mission could be critical in finding out why a large percentage of the population sees space exploration as a “waste of money.” Upon learning why this may be, the information could allow me to help create a more effective space program that has the full s...

- Introduction The objective of pool inspection is to protect public health and safety by ensuring the pools are maintained and operated in compliance with the regulations. There are many different aspects of the swimming pool that need to be checked to ensure its safety, not only the water quality, but also the areas around the pool including equipments, recirculation system and etc. Routine pool inspections allow the operators and the inspectors to identify potential problems that require repair or adjustments to avoid accidents from occurring....

- For centuries, many scientists and researchers have pondered on the idea of combining two or more substances together to create something new. These explorations have led to the idea of what kind of reactions would occur when diverse elements are combined. This is a concept known as chemistry, a part of science that corresponds with how matter is created from different properties and the process it goes through to create a new substance. Chemistry is a scientific concept that is used in everyday life and is a crucial part in the development of new technology and substances that allow today’s quality of life....

- In order to gain strong insight into the surface chemistry of silica we have perform a thorough literature search. Our goal is to identify the pioneer research performed on silica and silica supported catalyst. Particular interest lies in silica-water-cobalt and silica-alcohol-cobalt systems. This study is both on macro and micro level so that a complete theoretical base can be established. From this theoretical knowledge, key areas to look upon will be identified and a design of experiments will be established.... [tags: Chemistry]

- Space Exploration: An Odyssey (June 12th, 2016) The end of Second World War brought one of the most significant periods in human history. The world was filled with excitement about the new ideas and a zeal to turn those ideas into reality. Most of the countries were experiencing prosperity through high economic growth, financial stability, and a baby boom. Colonialism was diminishing with each passing day as colonies were becoming independent with Asian countries leading the torch of freedom. However, peace is by nature short-lived; the bonds between the Soviet Union and the United States of America bound by the imminent danger from the Nazi regime, started weakening again and the two champ...

Without cell phones, teens today would simply not know what to do with themselves. It is one thing after another. The world needs chemistry. Natural Resources involved in chemistry would be oxygen as one of the main ones. Oxygen is a very important element I guess you could say. Without oxygen we would not be here right now....

- Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at first, then in Germany, later on in England....

- Ever since the beginning of time, mankind has been fascinated with wonders of space. Before the mid-1900s, all mankind could do was gaze at the stars from Earth and wonder what it would be like to go into space. Man would look through telescopes and make theories on how the universe worked. During the mid-1900s, mankind finally was able to send a man into space and explore the wonders of space first hand. So why do humans explore space. Well, it is our fascination with the unknown. At first, all mankind did was look up and wonder how things became what they are now.... [tags: Space Exploration Essays]

- Chemistry and Synaptic Transmitters The most common psychoactive substances can be divided into depressants (i.e., alcohol, sedatives, hypnotics), stimulants (i.e., cocaine, amphetamines, ecstasy), opioids (i.e., morphine and heroine), and hallucinogens (i.e., PCP, LSD, cannabis). The brain has different effects to different psychoactive substances. They bind to different receptor types, and can increase or decrease the activity of neurons through several different mechanisms. Consequently, these psychoactive substances have different behavioral effects, different rates of development of tolerance, different withdrawal symptoms, and different short-term and long-term effec...

- Robert Boyle is considered both the founder of modern chemistry and the greatest English scientist to live during the first thirty years of the existence of the Royal Society. He was not only a chemist and a physicist as we know him to be, but also an avid theologian, a philanthropist, an essayist, and a beginner in medicine. Born in Lismore, Ireland to Richard Boyle, first earl of Cork, and Katherine Fenton, his second wife, Boyle was the youngest son in a family of fourteen. However he was not shortchanged of anything.... [tags: essays research papers]
