Rhodium

Last night at 3:00 AM a 10 kilogram bar of Rhodium escaped from the Delaware Depository located in Wilmington, Delaware in the United States. The bar of Rhodium, also known by its name on the periodic table, Rh is worth over 200,000 dollars. It thought to have escaped through an air conditioning vent. The Rhodium was being stored with other elements, such as Platinum, and Iridium but these elements did not escape, and they were found inside the depository’s vault safe and sound this morning. Authorities

however they do not have their own classification. All of these metals do not rust, they are resistant to oxidation and corrosion and they only break down when they are in high temperatures. Gold (Au), silver (Ag), platinum (Pt), ruthenium (Ru), rhodium (Rh), palladium (Pd), iridium (Ir), and osmium (Os) all have similar properties and are considered to be precious metals.1 Many of these elements were found in platinum ores. Scientists used aqua regia, an acid that can dissolve metals like gold which

accomplish the process of reducing toxic emissions, the first stage takes place on the reduction catalyst. The second stage of the process happens on the oxidation catalyst. Platinum and rhodium are the metals used for the reduction catalyst and oxidation catalyst uses platinum and palladium. The use of rhodium is very important because it enhances the purification of the gases to be emitted since palladium does not perform well in the purification process. Automobile converters reheat the gases

The discovery of palladium isn't new, but the use of palladium for fine jewelry only began in 1939. It's a shiny, silver element that is a great replacement for platinum and doesn't tarnish like silver does, which makes it terrific for jewelry applications. In fact, many people are searching for an alternative to platiunum that's affordable. Discovery of Palladium The mineral was discovered in 1803 by a chemist named William Hyde Wollaston. He was experimenting on platinum using hydrochloric and

Today’s newer vehicles come equipped with a catalytic converter. Designed to reduce emissions, the catalytic converter is an important part of your vehicle. Unfortunately, like anything else mechanical, the catalytic converter can break and fail. Luckily, you can reduce the amount of damage a failing catalytic converter causes by knowing the warning signs. So what are some symptoms that indicate your catalytic converter is failing? Here are three. 1. Reduced Acceleration and Engine Performance

Therefore, silver jewelry is often associated with another metal, plated to protect against stains. There are two types of coating for silver jewelry: nickel and rhodium. Nickel has a whitish, rhodium has a darker appearance. Rhodium is used in white gold and platinum jewelry plate, is much more expensive than nickel and give better protection and the silver under it. On the other hand a part of silver jewelry is plated. For example, highly polished

some extent for over exposure. On the other hand over exposure should be avoided to comply with the ALARP (as low as reasonably practicable) principles (DoH, 2012). Filter material Filter materials in mammography are made of molybdenum or rhodium. The purpose of filters is to let through the useful photons and to absorb unwanted low and high energy photons so that they stop reaching the image detector thus contributing to the formulation of the radiographic image (Bushberg et al, 2002).

Moving away from Classical Chemotherapeutics: A Review of Recent Advances in Targeted Chemotherapy As an elegant manipulation of the cell cycle, cancer pathways have demanded significant attention by the world’s researchers. From molecular biology to inorganic chemistry, each field has conducted a variety of studies to elucidate the pathways cancer manipulates in order to develop successful treatments. To this end, chemotherapy emerged as a prominent research field in the early 1960s and is a type

I chose this element because it’s very expensive and I wanted to know what makes it so expensive. Since its more expensive than Gold and I thought Gold was more expensive than any element. Also because I want to know why people say “an artist just went Platinum.” Platinum was discovered in 1735 by Julius Scaliger. The spanish term is Platina which means “little silver.” The atomic number for Platinum is 78. Platinum has 78 Protons, 117 Neutrons, and 78 Electrons. The atomic mass for this element
