标题 :Synthesis support resin
发明人：MAIKNER JOHN; MCINTOSH LESTER H
权利人:ROHM & HAAS
摘要:Provided is a support resin suitable for oligonucleotide synthesis comprising structure (II), wherein said particle comprises a crosslinked styrenic polymer, wherein -R 101 is hydrogen or alkyl, wherein -L 102 - and -L 201 - are independent optional linking groups, wherein each of -R 201 , -R 202 , and -R 203 is independently hydrogen or a substituted or unsubstituted hydrocarbyl group, and wherein -L is an functional group that is capable of forming a phosphate linkage with a nucleotide. Also provided is a method of making such a resin.

标 题 :Metal-loaded plastic scintillators for gamma-ray spectroscopy
发明人：FENG PATRICK L; CORDARO JOSEPH GABRIEL; MENGESHA WONDWOSEN; MYLLENBECK NICOLAS RICHARD
权利人:NAT TECH & ENG SOLUTIONS SANDIA LLC
摘要:Exemplary embodiments of several new metal-loaded plastic scintillators are reported herein, comprising sterically and electronically isolated organotin additive complexes. Distance-dependent quenching relationships have been used as design criteria for the selection and synthesis of these organometallic additives, resulting in increased light yields and improved gamma-ray energy resolution values relative to previously reported PS/PVT examples. Fast scintillation decay properties have also been characterized in the prepared scintillators, rivaling the kinetics of stilbene-doped bibenzyl and BC-422Q-1% while providing higher light yields than these reference materials.

标 题 :Photochromic indeno-fused naphthopyrans
发明人：CHOPRA ANU
权利人:TRANSITIONS OPTICAL INC
摘要:Photochromic materials comprising indeno-fused naphthopyrans having substituents comprising a 4-fluorophenyl group and a 4-aminophenyl group bonded to the 3-position of the indeno-fused naphthopyran are disclosed. The photochromic materials may exhibit faster fade rates as compared to similar indeno-fused naphthopyrans without a 4-fluorophenyl group and a 4-aminophenyl group bonded to the 3-position of the indeno-fused naphthopyran. Substituted 2-propyn-1-ols utilized for the synthesis of the indeno-fused naphthopyrans disclosed herein are disclosed. Photochromic compositions and articles, such as optical elements, incorporating the photochromic materials disclosed herein are also disclosed.

摘要:This invention relates to a composite material that comprises a support member that has a plurality of pores extending through the support member and, located in the pores of the support member, and filling the pores of the support member, a macroporous cross-linked gel. The invention also relates to a process for preparing the composite material described above, and to its use. The composite material is suitable, for example, for separation of substances, for example by filtration or adsorption, including chromatography, for use as a support in synthesis or for use as a support for cell growth.

摘要:This invention relates to a stable composite material comprising a support member that has a plurality of pores extending through the support member, and a macroporous crosslinked gel that is located in, and fills, the pores of the support member, in which crosslinked gel is entrapped a stabilizing polymer, which stabilizing polymer is neutral, linear or branched, non-crosslinked, and substantially water-insoluble. The presence of the stabilizing polymer is such that it allows the composite material to largely retain its porosity and morphology after being dried. The invention also relates to a process for preparing the stable composite material described above, and to its use. The stable composite material is suitable, for example, for separation of substances, for example by filtration or adsorption, including chromatography, for use as a support in synthesis or for use as a support for cell growth.
