Gold is widely used in modern day medicine to treat disorders. This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes, meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted thread-like mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold…

Aluminum is used in many of our household items. From pie pans to pop cans, Aluminum is a very common product. Charles M. Hall is an American Chemist who figured out how to produce aluminum using his electrolytic method. This method allowed aluminum to be mass produced. Hall was born on December 6th, 1863 in Thompson, Ohio. His father was a missionary and minister who was very educated. Education played a big part in his childhood. He read numerous science magazines and articles as a child. He…

Study of Stress Corrosion Cracking (SCC) in Alloys Jiang Jingxing 1. Introduction of Stress Corrosion Cracking Stress Corrosion Cracking (SCC) is the growth of cracks with a under the combined effects of a static stress and a specific chemical environment. All SCC failures involve a macroscopic brittle performance, and the ductility of the material is reduced. It is universally acknowledged that there is no single mechanism for stress corrosion cracking (Ford, 1984). Stress…

Glenn T. Seaborg was born in Ishpeming, Sweden in 1912, into a family known publically as being intelligent. However, in 1922, the family moved to California in order to expand their opportunities. In high school, he had no interest in science. However, a science class was required for graduation. A teacher named Dwight Logan Reid is given credit for his interest in the field. Due to his family’s finances, the nearby University of California at Los Angeles (UCLA) was his only option; due to its…

of glucose on the dissolution of these metal ions. The scope of this project could only focus on the effect of one variable; whether in fact, many other variables such as pH, salinity, and phosphate ions could also affect the dissociation of NMC particles. However, by focusing on one variable at time, a more general hypothesis could be drawn and utilized in the treatment of waste batteries. Background information on how glucose could form complexes with metal ions were studied from the Dolezal…

electron images of the catalysts, the Cu, Ce, and Nb particles on catalyst surface were distinguished. As shown in Fig. 6(a), copper may disperse as Cu2+ or CuO species on the catalyst surface. In Figs. 6(c) and (d), Ce and Nb were observed, because of metal oxides of CeO2 and Nb2O3 as shown in the XRD results (Fig. 2) and XPS data of Figs. 4 and 5. Comparing Figs. 6(a)–(d), the fresh BEA zeolite, showing column shape with the size of 20-30 nm was…

Question 1 Part A: General Topic Properties of stainless steel • Corrosion resistant • Good tensile strength • Good low and high temperature service • Appearance • Hygienic • Has a respectable friction coefficient Corrosion resistant Stainless steel has a chromium-rich rust protective oxide thin film on the surface known as a passive layer, in which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1,…

Properties of cold formed steel In general, cold formed steel has many important properties which make it significant building material, the main two properties of cold formed steel are: the yield point and the tensile strength and how are they related to formability of steel, most members in building industry are on high tensile loads, cold formed steel has a Huge tensile strength, however the ratio between the tensile strength and the yield strength is 1.2-1.8 .in addition to other good…

the mines. The rocket was a great success and he was famous for his rocket and what he had done/gone through to build it. The rockets purpose is to go into space or just very high in the air. It was built to go extremely high. With the special metal and fuel that…

process that changes over a refined metal to a more chemically stable shape, for example, its oxide, hydroxide, or sulfide. It is the slow destruction of materials (generally metals) by a chemical reaction caused by the environment. Corrosion is basic to ponder in two perspectives. Right off the bat, financial, which including the lessening of material misfortunes coming about because of the squandering ceaselessly or sudden disappointment of funnelling, tanks, metal segments of machines, ships,…
