The essential needs to make for those devices are the rare earth elements (REE) what are the fifteen lanthanides plus scandium and yttrium as defined by International Union of Pure and Applied Chemistry (IUPAC). Around 1950s‚ India‚ Brazil and South Africa were the leaders of the world’s REE production. But

Even so‚ that mineral and its 16 “rare earth” cousins—found in everything from batteries to catalytic converters—do help make the modern world go round. And‚ as the world’s manufacturers of such products have been reminded recently‚ China has a chokehold on their production. China’s grip on rare earths first

The reason I am a television is because one of Europium’s compounds is used as a red phosphor in television sets an yttrium-based phosphor. Now‚ you’re probably wondering if europium is a metal or non-metal. Europium is a metal. Europium is about as hard as lead and is quite ductile. It is the most reactive of the rare earth metals‚ and reacts quickly when exposed to air. It resembles

Issues surrounding China’s embargo on rare-earth elements exports have raised major concerns among the heavy buying countries around the world that rely on these resources. China currently dominates the global rare-earth production and exports of the international marketstrade. Devastating impacts may arise if China places a long-term embargo on its rare-earth elements

The global market for rare earth elements is expected to reach USD 10.96 billion by 2020‚ according to a new study by Grand View Research‚ Inc. Growing demand for metal catalysts such as Cerium and Lanthanum is expected to drive the market over the next six years. These metal catalysts find applications across a host of industries including automobiles‚ metallurgy‚ phosphors and glass among others. In addition‚ growing market for permanent magnets is expected to particularly boost the demand for

Imagine‚ being an animal locked in a to small cage‚ poisoned with cancer‚ drugged‚ and wishing you were dead. Animals being tested on have all these bad things happening to them and much‚ much‚ more. Many products such as cosmetics‚ chemicals and even bath products are tested on animals. Sometimes it gets in their eyes and can harm them enough to make them lose hair or even their lives. On the other side of the debate‚ people will argue that people should be allowed to experiment on animals because it helps

Animal Testing: The Destruction of Animals Animal testing‚ also known as animal experimentation‚ is the use of non-human animals in experiments and development project‚ usually to determine toxicity‚ dosing and efficacy of drugs before proceeding to human clinical trials (Biology online). These tests are to examine new products‚ such as vaccines‚ shampoos‚ household products‚ cosmetics‚ foods‚ and personal care products on the animals so they are “safer” for the consumer‚ which never is an absolute
