A facile room-temperature method for assembling colloidal copper sulfide (cu2-xs) nanoparticles into highly electrically conducting calcogenide material layer films utilizes ammonium sulfide for connecting the nanoparticles, while simultaneously effecting templating surfactant ligand removal. The foregoing process steps transform an as-deposited insulating films into a highly conducting films (i.e., having a conductivity at least about 75 s·cm−1).
Curable silicone emulsion composition
Provided is a curable silicone emulsion composition which has comparable curability without using an organotin compound curing catalyst, and for which the post-curing film properties thereof can obtain a comparable hardness, tensile strength, and elongation. A curable silicone emulsion composition characterized by including: (a) 100 parts by mass of an organopolysiloxane which includes a hydroxyl group bonded to at least two silicon atoms per molecule; (b) 0.01-5 parts by mass of an organohydrogenpolysiloxane which includes at least two silicon atom-bonded hydrogen atoms per molecule; (c) 1-10 parts by mass of the reaction product of an amino group-containing organoalkoxysilane and an acid anhydride; (d) 0.1-10 parts by mass of an epoxy group-containing organoalkoxysilane and/or a partial hydrolysis condensation product thereof; (e) 0.5-50 parts by mass of a colloidal silica; (f) 0.1-10 parts by mass of a bismuth compound; and (g) 50-500 parts by mass of water..

Fluorine-doped stannic oxide colloids and preparing same
A method for producing a colloidal alcoholic suspension of fluorine-doped sno2 particles. It also pertains to the colloidal loidal suspension thus obtained and to its uses, especially in the manufacture of an antistatic coating for an optical article, such as an ophthalmic lens..
Silicone coating composition and coated article
Provided are: a silicone coating composition that can be applied to the surface of a substrate without a primer, that has weather resistance and oxidation resistance, and that can be used to obtain a cured coating that has excellent adhesion, weather-resistant adhesion, interference pattern suppression, scratch resistance, and transparency; and an article that is coated with the silicone coating composition. The silicone coating composition comprises: an aqueous dispersion (a) of a core shell-type tetragonal titanium oxide solid solution that has a core of fine tetragonal titanium oxide particles in which tin and manganese are present in a solid solution and that comprises a shell of silicon oxide on the outside of the core; a polycarbonate and/or polyester urethane-modified vinyl polymer (b); a hydrolysis condensate (c) that is obtained through (co-)hydrolysis and condensation of an alkoxysilane that does not contain sulfur atoms and/or a partial hydrolysis condensate thereof; a curing catalyst (d); a solvent (e); and colloidal silica (f) as necessary.
