We study thermal-physical characteristics of nano-sized amorphous tungsten and of its oxide. It is shown that a nano-size amorphous metal gets into a nano-size crystalline state after heating up to temperatures much lower than the half-temperature of

WO3 and MoO3 nanowhiskers were grown from nanosize WO3 and MoO3 powders intensely irradiated with electrons in an electron microscope. Solid and hollow nanowhiskers of these materials were observed. A growth mechanism of nanowhiskers is suggested tha

The present paper discusses two different active influences of an electron beam on a nanosize sample.The first observed influence is the formation of nanoparticle agglomerates due to the beam charge. This can be likened to the formation of fine sand
