Neodymium Research Paper

723 Words3 Pages

Neodymium is a chemical element with symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air. Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach. It is present in significant quantities in the ore minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a "rare earth", it is a fairly common element, no rarer than cobalt, nickel, and copper, and is widely distributed in the Earth's crust.[3] Most of the world's neodymium is mined in China. Neodymium compounds were first commercially used as glass dyes in 1927, and they remain a popular additive in glasses. …show more content…

Analysis Of Nickel And Dimed By Barbara Ehrenreich

204 Words | 1 Pages

In a capitalist world, there are many opportunities to succeed, but an individual must be willing to work hard in order to ascend the social ladder. In Nickel and Dimed by Barbara Ehrenreich, she undergoes an experiment to see whether or not the average low-wage worker can get by in America. Ehrenreich claims that based on the wages that the low wage worker receives, he/she can not really get by and thus they don’t really have a way to get up out of poverty. However, the working poor do in fact have an opportunities to succeed, such as working up the corporate ladder from the bottom and saving money to build wealth, making Ehrenreich’s argument invalid.

Brenda Umana Daniels 17 July 2014 English 3 Nickel and Dimed: On (Not) Getting by in America Important; that’s the first word that comes to mind after the reading of this novel. Ehrenreich’s writing in Nickel and Dimed: On (Not) Getting by in America is very powerful, brutally honest, and extremely engaging. She gained so much from her experiences, and we gained even more when reading them. Although she cheated on few occasions, she gives a clear insight into what poverty is, and how a life in a low pay, heavy workforce is not a life at all.

Nickel And Dimed Analysis

1066 Words | 5 Pages

The Reality of the Sense of Space In Barbara Ehrenreich’s Nickel and Dimed, Ehrenreich takes a hands-on experimental approach in an attempt to immerse herself in the life of someone who lives on minimum wage. Although this is an experiment, Ehrenreich fully submerges herself in a lifestyle that she is not accustomed to. She remains open and honest to her readers, unveiling the difficulties of everyday life and the struggle to simply “make ends meet” in a world where prices are rising, but minimum wage remains stagnant. In relation to Ehrenreich’s experiences, a comparison can be made with Doreen Massey’s ideas of the degree of “mobility that influences the sense we have of space and place” (Massey p. 258). With Ehrenreich’s limited amount of resources, the world seems to be larger, as making her way around becomes more difficult.

Meitnerium was first synthesized by research scientists led by Peter Armbruster and Gottfried Münzenber at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1982. Meitnerium was produced when bismuth-209 was bombarded with accelerated iron-58 nuclei. The element was named after physicist Lise Meitner. Meitnerium is harmful due to its radioactivity. Meitnerium is a synthetic, radioactive metal and has only been produced in tiny amounts.

Chromium is a transitional element, with three stable forms. It is a neutrally charged stable form, but naturally occurs in the environment. Trivalent chromium is a +3 charge stable form of chromium that can be naturally oxidized from its neutrally charged version, occurring in the environment (Mertz et al., 1974; Barrett et al., 1985; Alexander et al., 1990). Hexavalent chromium is a +6 charge stable form of chromium which is the product of industry, and it is very toxic to living things. Hexavalent chromium may be reduced naturally in the environment to the less harmful trivalent chromium.
