Oilseed processing technologies include a sequence of intensive multiple heat treatments of seeds, oil and intermediate products. The optimization of these processes largely determines not only the price, but also the quality of the final products. Heat and mass transfer in multiphase multicomponent media are very complex. It is not yet possible to build adequate models of all processes theoretically. The thermophysical properties of the media under study change significantly with heating and changing pressure. Ne...

Nanofibers have attracted a lot of attention for applying in the third and fourth generation of solar cells to enhance their performance. In this paper, we investigate the possibility of obtaining and using successfully high-quality nanofibers based on perovskite: polymer composites (PPCs) in perovskite solar cells. First, the advantages, challenges and development directions of employing nanofibers as active layers (ALs) in organic solar cells (OSCs) have been reported to establish the principles needed to prepar...

In the oil and gas industry the problem of utilizing produced water is solved by recirculating it and using it as a basis for fluids for hydraulic fracturing and the well killing. During the oil production formation water is extracted in association with it to the surface. Its component composition depends on both the chemical nature and geological age of rocks and it is formed as a rule with a significant impact of oil and gas on water that leads to a wide variety of its chemical properties. In the process of wor...

In order to reduce the negative impact of PVC on the environment, it is becoming popular to produce composite materials based on PVC filled with various natural fillers. For example, bentonite as filler in a polymer matrix can absorb volatile toxic components and accelerate the degradation of PVC. Also in this paper, natural polysaccharides pectin and starch are considered as fillers. Pectin and starch are also capable of accelerating biodegradation of PVC. Nevertheless, the thermal stability of the resulting poly...
