The features of the technology of production of crushed stone from foam glass on specialized lines are described. The analysis of the sorption characteristics of the material was carried out, the dependences of humidity and thermal conductivity, the coefficient of thermal conductivity increment for each percentage of humidity were determined. The results of experimental research presented in the article show that the foam glass crushed stone manufactured on specialized lines fully meets the requirements for the materials of the insulating layer. This material has low values of thermal conductivity and water absorption, it has high resistance to aggressive environments, good strength indicators. The calculation of temperature fields was carried out using a computer program THERM, based on the finite element method.

We demonstrate and rationalize the effect of Au nanoparticles (NPs) on the hierarchical g-C3N4/CeO2 heterojunction. g-C3N4/CeO2 decorated with monodispersed plasmonic Au NPs was synthesized. Detailed analyses showed that CeO2 nanocubes and monodispersed Au NPs were evenly distributed over the 2D g-C3N4 surface, forming a robust interface enriched with abundant active sites. The structure enabled efficient separation of photogenerated charge ...
