Rundown about Holmium Oxide

Holmium oxide (Ho₂O₃) is the oxide form of the rare earth metal holmium. Holmium oxide is also known as holmia and holmium sesquioxide. This holmium oxide compound occurs in nature. Mostly, holmium oxide are contained in minerals like gadolinite and monazite. Holmium oxide has light yellow-orange, pale-yellow and beige colors. Holmium oxide is not soluble in water, but soluble in acids. The cubic structure is the only structure for holmium oxide compound. Holmium oxide has a melting point at temperature of 2415^oC. Holmium oxides has a few applications.

Holmium oxide is used as colorants for glasses and cubic zirconia

Holmium oxide is used as a specialty catalyst, phosphor and laser material

Holmium oxide is used in ceramics, glasses, phosphorous, and metal halides lamps

Holmium oxide is used in nuclear reactors to control the atomic chain reaction

Holmium oxide is used as calibration standard for optical spectrophotometers since holmium oxide solutions have sharp optical absorption peaks in spectral range 200-900nm

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...

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%) has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before, Hydroxyapatite Nanopowder is the main inorganic constituent of bon...

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...
