Particles of a carbonate compound, such as calcium carbonate, in an amorphous form may be precipitated from solution, freeze dried and compressed to form transparent or translucent objects. The objects may, for example comprise blocks, bricks or other shapes that may be used in construction of buildings. Advantageously the carbonate compound may incorporate carbonate ions obtained by capture of carbon dioxide from an atmosphere of air, flue gas, exhaust gas or the like. Captured carbon may be sequestered in the objects indefinitely.

A method for preparing a main chain scission-type polysilyl (meth)acrylate resin and application thereof. The method comprises: a cyclic monomer, vinyl monomer and vinyl silyl ester monomer are mixed in a solvent at a formulation ratio, then added a composite initiator in a mass percentage of 0.01-5% based on the total amount of the monomers, and reacted at a temperature of 25-150 C., and under the protection of argon or nitrogen gas, so as to prepare the main chain scission-type polysilyl (meth)acrylate resin, wherein the monomers are consisted of 5-95% by mass of cyclic monomer, 0-90% by mass of vinyl monomer and 5-95% by mass of vinyl silyl ester monomer. The resulting resin can not only be hydrolyzed on the side chain silyl ester segment under the effect of the sea water, but also occur chain scission on the main chain polyester segment under the effect of the seawater, so as to solve the dependency of the traditional self-polishing material on the sailing speed, effectively control the release of the antifouling agent at a constant rate, ensure the active substance preserved on the coating surface of the ships, and properly meet the antifouling requirements on the low sailing speed ships, submarines and off-shore oil platform facilities.

Marine coatings including cationic polymers hydrolyzable to nonfouling zwitterionic polymers, coated marine surfaces, and methods for making and using the marine coatings.

Described herein are fluid complex coacervates that produce solid adhesives in situ. Oppositely charged polyelectrolytes were designed to form fluid adhesive complex coacervates at ionic strengths higher than the ionic strength of the application site, but an insoluble adhesive solid or gel at the application site. When the fluid, high ionic strength adhesive complex coacervates are introduced into the lower ionic strength application site, the fluid complex coacervate is converted to a an adhesive solid or gel as the salt concentration in the complex coacervate equilibrates to the application site salt concentration. In one embodiment, the fluid complex coacervates are designed to solidify in situ at physiological ionic strength and have numerous medical applications. In other aspects, the fluid complex coacervates can be used in aqueous environment for non-medical applications.

This invention relates to a method for controlling microorganisms comprising coating a surface with a removable, antimicrobial film-forming composition.
