Sublimation crystal growth of yttrium nitride

What is yttrium nitride?Yttrium nitride is a dark gray powder, which is a kind of rare earth nitride. It has a very high melting point and keeps stable under high temperatures. So yttrium nitride can apply to refractory materials like titanium nitride and zirconium nitride. Yttrium nitride, Y5N14, was synthesized by a direct reaction between yttrium and nitrogen at ∼50 GPa and ∼2000 K in a laser-heated diamond anvil cell. High-pressure single-crystal X-ray diffraction revealed that the crystal s

Wurtzite Boron Nitride Crystal Growth in the Region of Cubic Boron Nitride Crystal Synthesizing

What is Wurtzite Boron Nitride?Wurtzite Boron Nitride (wBN) is a wide band gap BN polymorph with unique mechanical properties such as hardness and stiffness. Initially synthesized in 1963 by transforming hexagonal BN (hBN) under high temperature and pressure conditions, wBN can now be stabilized at atmospheric pressure to obtain high-quality samples. Our first-principles study investigates the electronic, vibrational, and optical properties of wBN across a broad range of pressures. We account fo

Aluminium Boron alloys are produced commercially

What is Aluminum Boride?About Aluminum Boride: They are stable to nonoxidizing acids but break down into oxidising solid agents and alkalis. Borides are used in semiconductors, superconductors, diamagnetic, paramagnetic, ferromagnetic, anti-ferromagnetic, turbine blades, and rocket nozzles. It is a layered structure, with Al atoms directly overlapping (A, A mode), and B atoms are filled in the triangular column formed by the direct overlapping of Al atoms; the boron layer is between the two alum

NiTi powder in cells culture with no growth inhibition

NiTi powder in cells culture with no growth inhibition. The medium's inductively coupled plasma (ICP) analysis also showed the separating rate in the different-size particles with the low separating rates of Ni and Ti. Although the NiTi alloy with high stability properties, a low degradation rate, and a low oxidation rate, the element of tolerance rate still needs to be concerned. The ICP data showed that the concentration of Ni increased with particle size. The data indicated that the NiTi allo

Study of CuO Nanowire Growth on Different Copper Surfaces

Cupric oxide (CuO) nanowires were produced by the thermal oxidation of copper surfaces at temperatures up to 450 °C. Three different surfaces, namely a copper foil, evaporation-deposited copper, and an application-relevant sputtered copper film on Si(100) substrates, were characterized ex-situ before and after the experiment. The development of oxide layers and nanowires was monitored in situ using grazing incidence small angle X-ray scattering. The number density of nanowires is highest for the

Is quartz silica a hazardous material

Crystalline silica (quartz) is not known to be an environmental hazard. Crystalline silica (quartz) is incompatible with hydrofluoric acid, fluorine, chlorine trifluoride, or oxygen difluoride. This material is hazardous under the OSHA Hazard Communications Standard (29 CFR 1910.1200). Rose quartz is a translucent, usually turbid, very coarse-grained variety of the silica mineral quartz found in pegmatites. Rose quartz is valued for its pale- to rich-pink color, possibly due to titanium. Silica
