Abstract:
The present invention relates to systems and methods for screening natural products such as secondary metabolites produced by engineered microbial strains.
Abstract:
A modified alkylresorcinol resin is prepared by reacting one or more alkylresorcinols with one or more aldehydes and optionally an olefinically unsaturated compound, The reaction may be carried out in the presence of a catalyst. The resulted modified alkylresorcinol resin can be used as a methylene acceptor that reacts with methylene donors in vulcanizable rubber compositions.
Abstract:
A thermoplastic resin composition (molding material) in which the problem that thermoplastic resins such as hydrogenated styrene polymers suffer a decrease in molecular weight upon melt molding and hence come to be mechanically brittle, is mitigated and which does not develop craze spots even when used in a high-temperature high-humidity atmosphere; and a substrate for optical recording media which comprises the composition. The thermoplastic resin composition comprises a thermoplastic polymer containing alicyclic groups and an addition-type stabilizer which can react by addition reaction with a free radical resulting from cleavage of the thermoplastic polymer.
Abstract:
The present invention relates to a composition comprising; components a) b) and d); wherein, component a) is a metal compound having the structure (I), component b) is a spin on high carbon polymer, having a polymer backbone comprising mono-cyclic aromatic hydrocarbon, fused-ring ring hydrocarbon moieties, or mixtures of these, having a wt. % of carbon from about 81 wt. % to about 94 wt. %, which is soluble to at least about 5 wt. % in a spin casting solvent, and wherein at least one, of said mono-cyclic aromatic hydrocarbon or said fused-ring ring hydrocarbon moieties, present in said spin on high carbon polymer, is functionalized with at least one alkynyloxy moiety of structure (VIII), and component d) is a spin casting solvent. The present invention further relates to using this composition in methods for manufacturing electronic devices through either the formation of a patterned films of high K material comprised of a metal oxide on a semiconductor substrate, or through the formation of patterned metal oxide comprised layer overlaying a semiconductor substrate which may be used to selectively etch the semiconductor substrate with a fluorine plasma.
