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

Carbon Nanotubes Specifications and Properties Carbon Nanotubes, simply CNTs, are allotropes of carbon with a round and hollow nanostructure. These barrel shaped carbon molecules have crucial properties, which are significant for nanotechnology, hardware, optics and other different fields of materials science and innovation. The carbon nanotube’s excellent quality as a strong and firm material laid the basis on many applications. Not to mention carbon nanotubes exceptional heat conductivity, electrical and mechanical properties, Carbon Nanotubes are used as additives to diverse auxiliary materials. In terms of rigidity and flexibility Carbon Nanotubes are the stiffest and strongest materials. These quality outcomes from the covalent sp2 bonds framed between the individual carbon molecules. Unlike Graphene , Carbon Nanotubes are either conductive or semiconducting along the tubular hub. Carbon Nanotubes also have absorption, fluorescence properties. Bulk Carbon nanotubes are util...

Boron Carbide Nanoparticles and Their Applications

Boron carbide  which has the chemical formula of B 4 C is one of the hardest materials among the ceramics materials after diamond and boron nitride. In addition to its hardness, it has high thermal stability, low density, chemical inertness and neutron capture property. At temperature above 1200  o C, its hardness exceeds that of the diamond. Thus, it is a crucial material for high technology applications such as abrasive for polishing and grinding media, ceramic amour applications for personal purpose and equipment, blasting nozzles, ceramic bearings, semiconductor applications for dielectric barriers, medical and nuclear applications. B4C (Boron Carbide) Nanoparticles (99.5+%, 40-60nm, Hexagonal)  show an outstanding hardness among the ceramic materials. Therefore, boron carbide nanoparticles are a suitable material for many high performance applications. Boron carbide nanoparticles can be used as polishing, lapping and grinding material for hard mater...
