This paper summarizes our theoretical understanding of supernova events in a “back of the envelope” way. It is intended to aid in the recognition and understanding of those events which are not “standard”, and which may provide the most insight.

The formation of the oriented collagen (Col) fibril arrays on polyimide films (PI-R and PI-HDR), which were rubbed by two kinds clothes with lower higher filament densities, was investigated. Col molecules assembled to be fibrils recognizing physicochemical properties films. In particular, dense nano-grooves PI-HDR effectively induced highly- densely-oriented arrays, occurred interfacial intera...

The interaction of pure graphene nano sheet and Al-doped with SO2 pollutant gas molecules was examined by density functional theory (DFT). Adsorption energies the transferred Mulliken charge were calculated. Doping Al on improved adsorption electronic properties graphene. Dos plots HOMO-LUMO band gaps showed that semiconductor materials. results revealed sensitivity graphene-based materials enh...

bending analysis of multilayer graphene sheets (mlgss) subjected to non-uniform shear and normal tractions is presented. the constitutive relations are considered to be non-classical based on nonlocal theory of elasticity. based on the differential transformation method, numerical illustrations are carried out for circular and annular geometries. the effects of nano scale parameter, radius of c...
