The emergence of new antibiotic-resistant bacterial strains means it is increasingly important to find alternatives traditional antibiotics, such as bacteriolytic enzymes. enzyme lysozyme widely used in medicine an antimicrobial agent, and covalent immobilization can expand its range possible applications. However, information on the effect immobilized preparations whole cells quite limited. Here, we demonstrate differential effects glycine charged (basic acidic) amino acids enzymatic lysis...
<title>Abstract</title> Nanophotonics relies on precise nanoscale structuring, yet conventional fabrication techniques remain complex and costly. Layered van der Waals (vdW) materials, with their intrinsic anisotropy high refractive indices, offer a promising route toward simplified nanostructuring tunable optical functionality. However, no vdW material has previously been shown to exhibit strong photorefractive effect—a key requirement for light-based modulation. Here we report giant...
The work is devoted to the study of properties active carbon fabric as a carrier chemisorbent for ammonia adsorption. Studies porous structure were carried out, result which it was found that has developed pore system. total volume sample 1.3 cm3/g, wherein sorption pores content 38% and percentage micropores in 88%. Active shown have hydrophobic properties. impregnated with copper (II) salts order obtain adsorbing ammonia. When sulfate applied fabric, crystallization additive occurs on its...
An important stage in the development of platinum electrocatalysts on carbon support is analysis their basic parameters. Cyclic voltammetry an effective tool for analyzing structural and electrochemical properties such electrocatalysts. Using Frumkin adsorption isotherms, contribution surface to hydrogen region was well described by three peaks corresponding different crystal structures. The screening carried out black supported black, reduced graphene oxide (RGO), nanotubes (CNTs),...
Platinum electrocatalysts on graphene-like supports have recently attracted research interest as components of electrochemical devices based hydrogen oxidation reactions in acid media due to their improved properties, high stability, and conductivity. Within the current work, adsorption recombination effects a proton hydroxonium graphene-based electrocatalyst were investigated using density functional theory. The interaction between ions platinum surface was simulated for various...
The present work is devoted to the study of dependence ammonia chemical absorber properties on conditions synthesis. As a carrier granulated active carbon AG type with sorption space maximum volume 0.512 cm3/g and micropore 0.414 was used. copper sulfate (II) salt taken as an ammonia-reactive additive. Samples were obtained by impregnating hot solution component. prepared two methods: traditional one, dissolving sample in water second use ultrasonic treatment. It found that increase CuSO4...
Bacteria appear to be an inevitable element of soil geochemistry because they participate actively in chemical transformations media components. One the factors determining composition bacterial population is resistance bacteria enzymes which hydrolyze cell walls. In following research, ( Priestia megaterium, Micrococcus luteus and Escherichia coli ) lysozyme pH range appropriate for soils investigated. All three species are proved most sensitive slightly alkaline conditions P. megaterium...
It was found that glycine, glutamate, lysine, histidine, and arginine increase the rate of Escherichia coli cell lysis by chicken egg lysozyme. The highest rates (lysis acceleration 7.0-8.5 times) are provided combinations following amino acids: 1) arginine, 2) 3) (all charged acids applied in concentrations 5 mM, concentration glycine is 1.5 mM). These added into food products with lysozyme as a preservative can significantly antibacterial properties latter. This could help shelf life human...
Abstract An advanced model of BaxSr1-xTiO3 Chemical Vapor Deposition is proposed. The implies that metal-organic precursor decomposition occurs primarily at the reactor surfaces. various parasitic solid phases (TiO2, BaO, SrO, etc.) taken into account. predicts deposition rate, phase composition and fraction in grown film as a function growth parameters.
The present paper is concerned with a research of sorption and bactericidal properties the fine metal particles applied on surface active carbon fabric by chemical sedimentation method. ascorbic acid natrium borane were used in study process as metals, copper silver reducing agents. Influence reducer nature onto porous structure, well characteristics obtained fibrous sorbent samples are shown. It determined that use for synthesis fabrics leads to considerable decrease specific volumes meso -...
В данной статье представлены результаты исследований влияния параметров процесса получения углеродного поглотителя аммиака и сероводорода на структуру кристаллической фазы активного компонента и, соответственно, его сорбционные свойства.

Non-equilibrium plasma is widely used for surface modification of polymer materials. Reactions active species with polymers lead not only to the modification, but formation gaseous products, which change composition and internal parameters. It results in dependence etching kinetics on quantity material been treated (on sample sizes a reactor). These phenomena are known as so called “loading effect” have studied treatment polypropylene polyimide films, poly(ethylene terephthalate) films...
The effect of lysozyme against various bacteria may depend significantly on the presence glycine and charged amino acids in solution. Immobilized effectively adsorbs bacterial endotoxin can be used for treatment sepsis. Lysozyme is able to bind immunoglobulins, which explain its opsonin functions.
