The use of a low-temperature plasma for the synthesis amorphous silicon carbonitride (SiCN) nanoparticles enables realization sintered bulk samples with high thermal stability. Amorphous SiCN are produced from mixture silane, methane, and ammonia utilizing mid-pressure, radio-frequency, continuous flow reactor. Particle characterization shows that largely some crystalline carbide domains <10 nm...

Abstract Moisture - in the form of water or ice – has adverse consequences on performance an aircraft including wing stall, tail loss thrust, engine flameout, and material damage arising from corrosion electrical shortcuts. During flight, a large flux supercooled droplets surface hybrid electric per unit time could result into icing. A prototype to detect accretion using acoustic emissions is d...

A creative hydrothermal synthesis method followed by calcination for vanadium nitride (VN) is reported. The oxygen reduction reaction (ORR) study of the catalyst shows that VN possesses a comparable catalytic performance to commercial Pt/C catalyst. The ORR catalytic activity study of vanadium nitride, vanadium carbonitride, and vanadium carbide reveals that tuning anions offers a promising rou...

Laser-induced Chemical Vapour Deposition of silicon carbonitride coatings and powders has been investigated using hexamethyldisilazane (HMDS) and ammonia as reactants. An industrial CW CO2-laser in parallel configuration has been used to heat up the reactant gases. HMDS dissociates in the laser beam and reactive radicals are formed which increase rapidly in molecular weight by an addition mecha...

The design and tailoring of material color for both aesthetic functionality is an ongoing topic materials science engineering research. In this work, a method developed to tune predict pseudogap energy any compositional variation B1-rocksalt structured Group 4 5 transition metal carbonitride. Optical properties bulk multicomponent carbonitrides were characterized using reflectivity spectra. ene...

The tribological properties of matrix and skeletal titanium carbonitride composites were studied in dry friction conditions air. Experiments on wetting the TiCN–Cr3C2 composite by nickel–chromium alloys copper using sessile drop method performed to choose composition ascertain whether samples could be produced impregnation porous skeleton. experiments showed that nickel its formed a low contact...

In this study, a novel and facile approach for the synthesis of ternary boron carbonitride (B-C-N) nanotubes was reported. Growth occurred by heating simple starting materials of boron powder, zinc oxide powder, and ethanol absolute at 1150 degrees C under a mixture gas flow of nitrogen and hydrogen. As substrate, commercial stainless steel foil with a typical thickness of 0.05 mm played an add...

Direct synthesis of large-scale ternary boron carbonitride single-walled nanotubes (BCN-SWNTs) via a bias-assisted HFCVD process was presented. The BCN-SWNTs were grown over the powdery Fe-Mo/MgO catalyst by using CH4, B2H6, and ethylenediamine vapor as the reactant gases. As high as 16 atom % nitrogen can be incorporated within the nanotube shells, with the boron content in the range of 2-4 at...
