THE diamond offers a variety of fascinating problems to the research worker interested in the correlation of physical properties with crystal structure, and the well-known variations of crystalline habit, colour, fluorescence, and so forth, are responsible for a bulky scientific literature. Its ...
The increasing demand for a wider access to additive manufacturing technologies is driving the production of metal lattice structure with powder bed fusion

Self-healing behaviour in a nanotwinned diamond composite, at room temperature, has been quantitatively evaluated through tensile testing. The phenomenon is shown to arise from a transition of atomic interactions from repulsion to attraction and the formation of nanoscale diamond ‘osteoblasts’, in anal...
Its large electronic bandgap of 5.45 eVallows diamond to withstand high electric fields and to be used in hazardous and radiation intense environments. High intrinsic electron and hole mobilityallows electronic charges to travel through the diamond structure with relative ease, which is ideal for high...

On The structure Of Deposited Diamond-Like Carbon Films Produced By Rf (13.56MHz) CH4 Plasma Plasma enhanced chemical vapour deposition technique is used to grow diamond-like carbon films using pure methane gas plasma. It is known that the structur... Ouchabane,Henda,Kechouane,... - American...
Effects of high temperature, up to 1700 °C, annealing in vacuum of CVD diamond on its structure, optical and mechanical properties are investigated. Translucent polycrystalline diamond films of thickness 0.06–1.0 mm were grown by microwave plasma CVD method, and examined with transmission electron ...
For superhardness of about 100GPa, the elastic modulus of 70–500GPa and the universal hardness of about 17–22GPa (loads between 30 and 100mN) compare well with the hardness of a single-phase nanocrystalline diamond. Besides this extremely high hardness, the coatings also have a very high ...
