A recent trend in electronic technology deals with a sharp performance increase within decrease dimensions and mass of devices. High-performance thermal interface materials (TIM) primarily thermal pastes are indispensable to application. A number of filler materials: ceramics (aluminum nitride, silicon carbide, alumina) metals (aluminum, copper) and graphite were considered to apply. The data containing average particles size, specific surface area, and maximal volume and mass fraction for various materials was obtained. The thermal conductivity of samples with aluminum and graphite dramatically exceed values obtained within mathematical models’ calculation. The highest thermal conductivity values were obtained for SiC (1.37 W/(m·K)), AlN (1.09 W/(m·K)), C (2.85 W/(m·K)) and Al (1.20 W/(m·K)), that mad the mentioned above materials the most promising for high-performance thermal pastes.

Nanotubular titanium oxide is widely known as a prospective semiconductor photocatalyst for the process of water splitting. Its photoelectrochemical (PEC) efficiency can be improved by doping with 3d metal. In this work, the synthesis of nanotubular titanium oxide (NTO) was carried out by anodizing titanium substrates using two doping techniques. First, Ni-doped TiO₂ was obtained by immersion in Ni salt solution; second, an ethylene glycol-based fluoride electrolyte containing Ni²⁺ ions solution was used. The obtained samples were analyzed using SEM, XRD, and photoelectrochemical methods. The produced Ni-doped NTO exhibited photocatalytic activity twice as high as that of nondoped NTO. Additionally, it was found that the immersion technique initiated a shift of the incident photon to converted electron (IPCE) spectra to the visible part of the spectrum.

In this paper, an experimental examination of defects in anodization of aluminum of the industrial grade A7E is presented. A two-step method of anodizing was used in an electrolyte containing 20% wt. % sulfuric acid at 0 ° C at constant voltage. Micro-video recording was carried out in both anodizing stages to examine anodizing process on a micrometer scale, and to determine the corresponding macro-scale effects indicating incorrect anodization process. Macro-scale effects in the form of gas evolution were detected. Subsequently confirmed on the surface of the coating from which it occurred, using scanning electron microscopy. Methods for preparing samples subject to anodization are proposed to reduce the number of defects. The results should lead to industrial implementation of inexpensive and high-quality nanoporous anode materials with a variety of applications.
