The Use of Electrolytic Hydrogen Bubbles for New Method of Juice Concentration
Abstract: Currently, juice concentrates are produced by separating water from fresh juice. For the production of juice concentrates, one of the following methods is used: evaporation of freezing water or the diaphragm method. During evaporation, the juice is heated in a vacuum in special trays, but this heat is not brought to the boiling point, since during the boiling process all useful substances will be destroyed. The mass obtained after evaporation …

Hydrogenated Nitrile Butadiene Rubber (HNBR): A Comprehensive Review
Abstract: HNBR is produced by the hydrogenation of nitrile rubber (NBR) using either a homogeneous or heterogeneous technique. NBR is a copolymer of butadiene and acrylonitrile monomers. The hydrogenation process involves adding hydrogen to the nitrile butadiene copolymer, which results in improved resistance to heat, oxidation, and chemicals compared to NBR. This process alters the molecular structure of the rubber, providing it with superior properties compared to its unmodified counterpart, NBR. …

Chlorella lipid oil for biofuel production obtained by a new method of high quality concentration of Chlorella
Abstract: Chlorella concentrates are unique due to the large amount of high-quality lipid oil produced from them, which is a high-quality biofuel. The production of high quality lipid oil requires the production of Chlorella concentrates with low water content (as a foam product). Existing methods of centrifugation or microfiltration for the concentration of chlorella are expensive andineffective. The article presents a new developed method for obtaining high-quality lipid oil, in which …
