- Synthesized silver nanoparticles using extracts of Calendula officinalis and Arnica montana callus biomass. It is shown that the rate of nanoparticle formation is influenced by plant cultivation conditions. It was found that in the presence of an extract obtained from callus, the process of nanoparticle formation occurs rapidly. The synthesized silver nanoparticles were studied by spectroscopy.

– The paper is devoted to the application of the method of discrete input pulse energy (DIPE), which today is one of the most effective ways to achieve high energy performance in food and chemical technologies. The results of experimental studies of aqueous extraction of chelidonium majus using the method of DIPE are presented. Physico-chemical parameters of the aqueous extract of chelidonium majus depending on the temperature of treatment are given.

The work provides the description of one of the realizations of the process of catalytic hydration of acetylenic compounds using a homogeneous catalyst based on the gold (I) complex with water-soluble organophosphorus ligands. In particular, we are to present the process of catalytic hydration of acetylene. The reactor unit consists of a gas-liquid reactor and a column for the separation of the reaction product, acetaldehyde, is also is used. When developing the process, attention was paid to the peculiarities of using a homogeneous catalyst and preventing its entrainment from the reaction unit along with the reaction product.

The paper describes the production of hydrogel composites, which are crosslinked structures based on polyacrylamide and poly-2-ethyl-2-oxazoline (aquazole); study of the kinetics of swelling of the obtained hydrogels and study of the thermomechanical properties of the obtained material. The method of synthesis of hydrogel composites and their physicochemical and thermomechanical properties and graphic representation of these laws considered was present. A number of samples with different ratios of starting materials synthesized and the dependence of their properties on the structure was established.
