Graphene and hexagonal boron nitride are typical conductor and insulator, respectively, while their hybrids hexagonal boron carbonitride are promising as a semiconductor. Here we demonstrate a direct chemical conversion reaction, which systematically converts the hexagonal carbon lattice of graphene to boron nitride, making it possible to produce uniform boron nitride and boron carbonitride str...
The increasing use of titanium and its alloys in the manufacture implants results from simultaneous presence excellent biocompatibility, relatively low density, high mechanical properties, corrosion resistance. Unlike application characteristics, is classified as a difficult-to-machine material. Therefore, one constant challenge for implant manufacturers to correctly choose turning tools each a...
The study presents the corrosion behaviour and wear response of pulsed electric current sintered binderless TiC 50 N , 70 30 90 10 based ceramic composites, consolidated by spark plasma sintering (SPS), relative densities were evaluated using Archimedes principle. microstructural evolutions samples examined through various microscopy techniques, their susceptibility to in aggressive chloride en...
MgAl2O4/Ti(C,N) composites were synthesized through aluminothermic reaction between Al,TiO 2,MgO powders and phenolic resin in coke bed condition. Effect of addition of carbon black and sugar into the mixture at different temperatures were investigated. The phases and microstructures of samples were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). MgAl 2O4 ...
Cermet is an advanced class of material consisting a hard ceramic phase along with metallic binding the combined advantages both and metal phase. The superior properties this materials are particularly useful in high-temperature, tribological, machining applications. This review paper seeks to provide comprehensive overview various cermet systems. More specifically, most commonly used systems b...
In this study, a graphene-vanadium carbonitride (G-V(C, N)) hybrid is reported as a novel support for the Pt catalyst in methanol oxidation. The catalytic activity of the Pt/G-V(C, N) hybrid for methanol oxidation is greatly enhanced compared with that of a commercial Pt/C catalyst with carbon black as the catalyst support. The outstanding catalytic activity of the Pt/G-V(C, N) catalyst suggest...
