A quantum dot including a semiconductor crystal particle having a particle diameter of 20 nm or less, and a ligand having two or more functional groups for interaction with the semiconductor crystal particle coordinates to two or more sites on a surface of the semiconductor crystal particle. A quantum dot with enhanced stability through surface modification on the semiconductor crystal particle by using a ligand which has two or more functional groups for interaction with the semiconductor crystal particle, and which coordinates to two or more sites on the semiconductor particle surface.

An antibacterial leather uses the organic silica gel as the main component, uses the carboxymethyl chitosan silver as the antibacterial factor, and uses the modified nano-silica and the modified layered double oxide as the flame retardant factor. The synergistic effects between the components, such as the good binding between carboxymethyl chitosan silver and the substrate, the synergistic flame retardant effect between flame retardant factors, the bonding effect between modified nano-silica and dimethicone, and the synergistic effect between the high-viscosity dimethicone and the low-viscosity dimethicone are utilized to improve the process, thereby obtaining a good antibacterial, flame retardant and other properties, meanwhile meeting the requirement for the material mechanical properties and environmental protection.

The present invention relates to a method for producing biodegradable fibers on the basis of a silane compound, said silane compound being crosslinked during production and, at least to some extent, an organic acid being incorporated into the forming crosslinked structure via covalent bonds and/or contributing to the crosslinking. The present invention also relates to the fibers that can be produced by the method according to the invention and to the use thereof.

A methylsilicic acid hydrogel is produced by reacting a solution of sodium methyl siliconate with a gaseous acid agent. The resulting product is vacuumised to remove residual gas, and washed with water. A significant OH-group content in the hydrogel, which results from bubbling the gaseous acid agent through the solution of sodium methyl siliconate, makes it possible to increase the selectivity of the adsorption properties when the hydrogel is used in medicine and veterinary science.
