Praseodymium Metal and Its Applications

Praseodymium(Pr) is the one of rare earth metals with atomic number 59. Praseodymium is a soft, silvery, malleable and ductile metal valued for its magnetic, electrical, chemical and optical properties. Due to praseodymium high potential reactiveness it is very hard to find a pure praseodymium metal in nature. It slowly develops a green oxide coating. Praseodymium was found by separating didymium into two different elements, which one of them was praseodymium and other was neodymium, in 1885 by the Austrian chemist Baron Carl Auer von Welsbach. The name praseodymium comes from the Greek prasinos meaning “green” and didymos “twin”. Praseodymium is stable only in aqueous solution with the 3+ oxidation state. Aqueous praseodymium ions are yellowish-green. Large amounts of praseodymium are found in monazite and bastnasite minerals. Praseodymium could be isolated by ion exchange and solvent extraction and through calcium reduction of anhydrous chloride or fluoride. The very first use of praseodymium was glass coloration yielding a yellow-green glass. The first enduring commercial use of purified is in the form of a yellow-orange stain for ceramics.
Praseodymium is used to create high-power magnets notable for their strength and durability
Praseodymium is used as an alloying agent with magnesium to create high strength metals that are used in aircrafts engines
Praseodymium fluoride forms the core of carbon arc lights, which are used in the motion picture industry for studio lighting and projector lights
Praseodymium is used to color ceramics yellow
Praseodymium as component of didymium glass is used to make certain types of welder’s and glass blower’s goggles
Praseodymium compounds give glasses and enamels yellow color
Praseodymium oxide is used as catalyst in solid solution with ceria or ceria-zirconia
Doping praseodymium in fluoride glasses allows it to be used as a single mode fiber optical amplifier
Flame lighters flints use misch metal containing praseodymium to produce sparks by friction
Praseodymium is used in nickel metal hydride rechargeable batteries for hybrid automobiles
Praseodymium is used in high-intensity permanent magnets, which are essential in electric motors and generators used in hybrid cars and wind turbines

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...
