The mechanical properties of silicon nitride deposited using hexachlorodisilane (HCD) as the silicon precursor have been studied using nanoindentation. The hardness, elastic modulus and fracture resistance were found to be significantly lower for HCD nitride films than they are for nitride films deposited using dichlorosilane (DCS) as the silicon precursor. The addition of carbon to HCD nitride films...
The mechanical properties of Nocadia before and after metallization are determined by nanoindentation technology. Nocaida is a land of rod-shaped bacteria with submicrometer in diameter and 3-10 mum in length. The elastic modulus of metallized Nocadia, Nocadia and resin is 14.16 GPa, 9.50 GPa and 5.72 GPa, respectively. The hardness is 0.60 GPa, 0.27 GPa and 0.30 GPa, respectively. There is a great...
The purpose of this study was to prepare a 3D nanocomposite bone substitute prepared from gelatin (GEL) and synthesized hydroxyapatite (HAP) in order to mimic natural bone feathers through a novel layer solvent casting combined freeze-drying technique. The adhesion between superimposed layers was ensured by applying a GEL solution. Furthermore, samples were cross-linked with 1% glutaraldehyde (GA)...
