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

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

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...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
