CdS thin films obtained by thermal treatment of cadmium(II) complexprecursor deposited by MAPLE technique
PublicationCienkie warstwy kompleksu [Cd{SSi(O-But)3}(S2CNEt2)]2 zostały osadzone na podłożach Si przy użyciu techniki MAPLE (ablacja laserowa z zamrożoną matrycą). Otrzymanie warstw CdS było możliwe dzięki zastosowaniu obróbki termicznej podłoży z naniesionym prekursorem. Powierzchnia filmów była analizowana pod kątem morfologii przy użyciu mikroskopii sił atomowych (AFM) oraz pomiarów elipsometrycznych (SE).

Biopolyols obtained via microwave-assisted liquefaction of lignin: structure, rheological, physical and thermal properties
PublicationThe present study examined the application of polyols obtained via microwave-assisted liquefaction of lignin in the production of rigid polyurethane foam. Lignin was liquefed in crude glycerol and 1,4-butanediol at diferent temperatures (130–170 °C), without a catalyst and using various biomass concentrations (15 and 30 wt%). The physicochemical properties, process yield, and FTIR-based identifcation of the obtained polyols were...

Analytical solution of non-stationary heat conduction problem for two sliding layers with time-dependent friction conditions
PublicationIn this article we conduct an overview of various types of thermal contact conditions at the sliding interface. We formulate a problem of non-stationary heat conduction in two sliding layers with generalized thermal contact conditions allowing for dependence of the heat-generation coefficient and contact heat transfer coefficient on time. We then derive an analytical solution of the problem by constructing a special coordinate...
