The Chemical Warfare Service The lessons learned from the involvement of the United States in World War I would identify the need for a military organization that specialized in Chemical Warfare. The use of chemical weapons was one of the most deadly and effective tactics experienced by both sides during the trench-style warfare. Due to the concern that the chemical weapon strategies of the First World War would continue on in future armed conflicts, the United States Army created the Gas…

the large and small scale to achieve such an end. Recent technological and scientific advancements have enabled scientists and engineers to protect and benefit the economy, people and the planet through implementation of Green Chemistry. The American Chemical Society Green Chemistry Institute describes green chemistry as a different perspective on how chemistry and chemical engineering should be done to reduce waste, conserve energy, and utilize replacements for hazardous substances. Through a…

Abstract: Electrochemical machining (ECM) is a technique of eradicating metal by an electrochemical procedure. It utilizes an electrolyte and electrical current to ionize and eradicate metal atoms. Electrochemical Machining is a relatively ancient machining system which basis were laid way backside in the 19th century. The process has enhanced extremely everlastingly since, thus becoming an extremely defined practice with gigantic limitless application possibilities across engineering. In this…

WHAT IS FORMALIN? Formalin is the trade name for an organic compound made by formaldehyde and water. It has the chemical formula CH2O and its chemical structure is as shown in figure.1. Uses: Formaldehyde is used mainly in the production of plastics (such as urea-formaldehyde plastics which is used in many manufacturing processes due to its useful properties such as flexural modulus, and a high heat distortion temperature, high surface hardness, low water absorption, high tensile strength, mold…

of terrorism that holds a massive danger over anybody, with the power to kill millions in just days or months. Some various chemical weapons that can be used or have been include: Anthrax, Smallpox, Ebola, Plague, and Tularemia. Each one of these viruses contains the power to harm, severely disable, or kill a person. From Pneumonia to shock and paralysis the wrath of chemical agent produces much more torturous effects then a gun-wound in a war scenario. To put into perspective, “An airborne…

experience? Moving closer to examine the chart, I felt as if the bright colors on the chart were generating warmth (energy) and that chart was an exhibit of the Periodic Table. For years, different people ventured to group elements by their chemical traits. However, Dmitri Ivanovich Mendeleyev (1834-1907) a Russian chemist is first to devise a periodic table of elements.…

varied according to the source from which it came” (RSC). Boisbaudran suggested the name gadolinium for the new element after the 18th century chemist and mineralogist Johan Gadolin. Pure metallic gadolinium was first prepared by French chemist and engineer Felix Trombe in 1935. A few months later Georges Urbain, Pierre Weiss, and Felix Trombe discovered that gadolinium becomes ferromagnetic at about room temperature, which was the first pure element to show this property other than the three…

the opportunity to chase my dream of becoming a physician. Being inclined to study medicine was not something I envisioned at a younger age or during my undergraduate career. Initially, my goal coming out of high school was to pursue a career in chemical engineering to work in the oil and gas industry. This career path, at the time, seemed like a perfect…

The Nanotube Introduction: Nanotubes, specifically the carbon nanotubes are just one of the handful of structures engineers and scientist use today that fall in the nanoscale category. Structures in the nanoscale category are usually between 1-100 nanometers, which one nanometer is one-billionth the size of a meter. A confusing yet beneficial property found in materials at the nanoscale is a concept call quantum called quantum mechanics. In quantum mechanics the laws of classic or Newtonian…
