Nanoparticles of the [Fe(NH(2)trz)(3)](tosylate)(2) spin crossover complex of 3-4 nm size were synthesized and dispersed in a nonionic surfactant. This colloidal system exhibits thermal spin crossover phenomena associated with a virtually first order transition. By thermal treatment the colloidal suspension can be transformed into a fibrous structure forming a gel.

The growth kinetic and size decreasing process of tungsten rod‐like crystals by heating in the iodine vapour are studied. Effects of tungsten filament temperature (2400 – 3500 K), iodine concentration (to 6 mg/cm3) and water contents (0.01 – 0.05 mg/cm3) are shown. Maximal growth rate of tungsten whiskers to 30 μm/min. Stopping of the growth and following removing by iodine reactions take place after heating to 3500 K.
