A method of making a lithium alkylsiliconate composition comprising adding an alkylalkoxysilane to a first mixture comprising lithium hydroxide and water to form a second mixture comprising a lithium alkylsiliconate and an alcohol, wherein i) the mole ratio of lithium hydroxide to alkylalkoxysilane is from 0.9 to less than 1.1 and the water is from 89 to 93 mol %, or ii) the mole ratio of lithium hydroxide to alkylalkoxysilane is from 1.1 to 1.4 and the water is from greater than 93 to 99 mole %.

Guanidine-functionalized particles and methods of making and using such particles.

Self-immolative polymers degrade by an end-to-end depolymerization mechanism in response to the cleavage of a stabilizing end-cap from the polymer terminus. Examples include homopolymers, mixed polymers including block copolymers, suitable for a variety of applications. A polyglyoxylate can be end-capped or capped with a linker as in a block copolymer.

A method of manufacturing a wire grid pattern includes providing a laminate having a base member, a metal layer disposed on the base member, a mask layer disposed on the metal layer and containing a metal oxide, an adhesive layer disposed on the mask layer, and a patterned resin layer disposed on the adhesive layer and formed by irradiation of first light; and irradiating the laminate with second light. The adhesive layer may comprise a silane coupling agent.

An improved catalyzed reaction of silicon metal with alcohol is provided for the formation of alkoxysilanes, particularly trialkoxysilanes. The Direct Synthesis reaction of silicon metal and alcohol employs a catalytically effective amount of a copper-aluminum alloy as a catalyst precursor and further benefits from an effective catalyst-promoting amount of a catalyst promoter.

Novel intermediates for the complete synthesis of vitamin D are provided that allow a great versatility of functional groups in the final vitamin derivatives. Vitamin derivatives that are epimeric in position 3 and vitamin derivatives with a wide range of functionalities in position 18, including compounds with isotopic labelling are provided.
