Recently, transition metal nitrides have been considered as possible alternatives to noble metals as plasmonic materials. In particular, the local surface plasmonic resonance (LSPR) of refractory transition metal nitrites such as TiN and ZrN is an attractive option for plasmons. Using FDTD simulations, the extinction, absorption and scattering of the TiN nanocube diameter were calculated at about 42 nm with field strength “modes” at different separation distances. We investig

Refractory metals, such as cobalt, chromium, tantalum (Ta), niobium (Nb), and titanium (Ti) alloys, have been used in implants because of their excellent corrosion resistance. Cytotoxicity usually depends on the ionization tendency of the metal used. In order to evaluate the biocompatibility of refractory metals, titanium, hafnium, niobium, tantalum and rhenium were implanted in rats and organized by X-ray scanning analysis microscope (XSAM) and electron probe microscope anal

Nano powders are particulate materials that exhibit basic structural properties on a scale of 1-100 nm. The field of application of nanopowders is based on their unique properties, such as a very high specific surface area, increased chemical activity of atoms and molecules at the interface, and high absorption. Many of these properties are atoms and molecules on the surface versus the bulk state. Since the properties of nanoparticles are mainly related to their size, it is u
