In this study, bioactive composite systems based on natural polymers (chitosan and lignin) were prepared in study. The structural, mechanical, morphological properties of chitosan-based materials containing various amounts lignin filler investigated. infra-red IR spectroscopy data confirmed the formation chemical bonds between components obtained composites. mechanical film samples studied air physiological solution. It was demonstrated that breaking elongation values wet state higher...
The past two decades have been marked by an increased interest in the synthesis and properties of geoinspired hydrosilicate nanoscrolls nanotubes. present review considers three main representatives this group: halloysite, imogolite chrysotile. These hydrosilicates ability spontaneous curling (scrolling) due to a number crystal structure features, including size chemical composition differences between sheets, (or void gibbsite sheet SiO2 tetrahedron, case imogolite). Mineral nanotubes...
Bioactive biodegradable chitosan films containing chitin nanofibrils have been developed for use as face masks in cosmetology. It was found that thermal modification of promotes the transformation polymer into insoluble form without alkali or aldehydes. The structure and properties were studied by IT spectroscopy, atomic force microscopy, thermogravimetric analysis, X-ray structural analysis. Analysis infrared (IR) spectra showed addition accelerates process composite films. This is apparent...
Here, we study a performance of nanotubular Mg 3 Si 2 O 5 (OH) 4 /TiO hybrid adsorbent/photocatalyst in the process decolorizing an aqueous solution crystal violet.The composite material was produced by hydrothermal treatment with one or more subsequent cycles TiCl and vapor-phase hydrolysis according to molecular layering technique.Decolorization observed situ UV-VIS spectroscopy.It found that TiO deposition yields times improvement decolorization performance.Depending on phase...
Abstract Asbestos (Mg‐hydrosilicate; chrysotile) is known to cause pleural diseases, pulmonary fibrosis and lung cancers, via mechanisms strongly depending on diameter‐length ratio possibly metal content. A critical question whether synthetic hydrosilicate nanotubes (NTs) of short length possess little toxic potential compared chrysotile. Five Mg‐ two NiNTs different lengths were assessed for cytotoxicity pro‐inflammatory responses in THP‐1 macrophages human bronchial epithelial cells...
