摘要:
The present invention provides methods for obtaining highly stereoregular polyacetylenes from organorhodium catalysts in aqueous media in high yield. These methods afford substantial advantages in that they are rapid, economical, and utilize environmentally benign solvents. The present invention further provides methods for making thin films of polyphenylacetylenes that are tough and transparent.
摘要:
This invention provides methods for reducing emissions of mercury from a cement plant comprising at least a kiln (6), a particulate collection device (10), collected particulates, an exhaust gas stream (8b), a heater, and a mercury scrubber, wherein the heater and mercury scrubber are upstream from the kiln. The methods comprise directing the collected particulates through the heater, to form volatilized mercury species from the collected particulates; directing the collected particulates from the heater downstream toward the kiln; and directing the volatilized mercury species to the mercury scrubber. The exhaust gas stream (8c) exits the particulate collection device and is not directed into the heater. Optional steps include injecting a mercury sorbent at one or more points between the kiln and the particulate collection device.
摘要:
Optical glasses and polymers are described that incorporate homogeneously dispersed fullerene molecules. The resultant materials may be used as optical filters, the cut-off frequency being easily adjustable by changing the fullerene content. To prepare glasses fullerene molecules are firstly functionalized by amination prior to being incorporated into a sol-gel process to prepare the glass. To prepare polymers a pre-existing polymer may be subject to fullerenation, or fullerene may be copolymerized with a selected monomer.

摘要:
Disclosed is a composition, in particular a dispersion, which contains nanofiber material in at least one organic matrix component, said nanofiber material being pre-treated in at least one method step for adjusting the physical properties of the composition.
摘要:
The present invention relates to a novel process of preparing branched polymers by cyclotrimerization and branched organic materials containing triaroylbenzene moieties as base structural unit. The polymerization is a simple one-pot reaction, strictly regioselective and highly functionality-tolerant giving oligomeric and polymeric polymers with high degree of branching (up to 100%) in high yields (up to 99%). The polymers are processible, easily film-forming, transformable (curable) into thermosets by heat or irradiation, and readily crosslinkable by UV irradiation to give patterns with nanometer resolution. The polymers of the present invention can be blend with a variety of macromolecules for general use. The polymers can be metallified utilizing organometallic acetylene as building blocks and ceramization of the patterns of the obtained polymers afford ferromagnetic ceramic patterns with high resolution.

The present invention relates to methods for identify subjects for responsiveness to adenosine agonist treatment. Another aspect of the present invention relates to methods to predict a relative infarct size in response to ischemia reperfusion injury. In particular, the present invention relates to methods for to identify responsiveness to adenosine agonist treatment and/or relative infarct size by identifying a sequence differences such as mutations and/or polymorphisms in the human A1 adenosine receptor (A1-AR) gene that alters the stability of the A1-AR mRNA. Other aspect of the present invention relates to methods to identify responsiveness to adenosine agonist treatment and/or relative infarct size by identifying a sequence differences, such as mutations and/or polymorphisms in the human A3 adenosine receptor (A3-AR) gene that alters the A3-AR protein function. Other aspect of the present invention also relate to kits and assays to detect sequence differences in the human A1 adenosine receptor (A1-AR) gene and/or A3 adenosine receptor (A3-AR) gene.
