Europium Metal and Its Applications

Europium(Eu) is one of the rare earth metals with atomic number 63. In 1886, French chemist Eugene-AntoleDemarcay identified europium by spectroscopic lines in “samarium”. In 1901, europium was successfully isolated by using repeated crystallizations of samarium magnesium nitrate. Afterwards, in 1904 French chemist Georges Urbain also succeeded in purifying europium by separating it from impure gadolinium using bismuth magnesium nitrate. Europium is named after continent Europe.Europium is a moderately hard, ductile and silvery-white metal that readily oxidizes in air and water. Europium has no significant biological role and is relatively non-toxic compared to other heavy metals. Europium is the one of the least abundant element in universe; nearly 5*10-8% of all matter in universe is europium. Europium has the second lowest melting point and the lowest density among all lanthanides.
Europium is used in the printing of euro banknotes. It glows red under UV light and frogeries can be detected by lack of this red glow
Europium is used in manufacture of fluorescent glass
Europium is used low-energy light bulbs contained a little amount of europium to give more natural light by balancing the blue light with a little red light
Europium is used as excellent absorber of neutrons, making it valuable in control rods for nuclear reactors
Europium-doped plastic is used as a laser material
Europium-doped plastic is used in making thin super-conducting alloys
Europium salts are used for newer phosphorescent powder and paints
Europium is used in quantum memory chips which can reliably store information for days at a time; these could allow sensitive quantum data to be stored to a hard disk-like device and shipped around the country
Europium fluorescence is used to interrogate biomolecular interactions in drug-discovery screens
Europium is used in manufacture of fluorescent glass

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 ...
