标 题:Reversible terminators for dna sequencing and methods of using the same
发明人：JAIN MOTI; ZHOU WEI
权利人:CENTRILLION TECH INC
摘要:The present disclosure provides methods of sequencing polynucleotides and compounds, compositions for sequencing of polynucleotides, and synthesis of such compositions. The chemical compounds include nucleotides and their analogs which possess a sugar moiety comprising a cleavable chemical group capping the 3′-OH group and a base, but without covalently bounded dye. The cleavable chemical group is reactive to form covalent bond(s) with a dye used to confirm the presence of the expected base-pairing. The cleavable chemical group capping the 3′OH group can be removed together with the covalently bounded dye. Furthermore, after the cleavable chemical group is cleaved, the free 3′-OH group can be active in continued elongation. Example chemical compounds according to the present disclosure are shown as Formulas (II) and (V):

标题:Compositions and methods for synthesis of 2,3-dichloro-1,1,1,2-tetrafluoropropane and 2,3,3,3-tetrafluoropropene
发明人：SUN XUEHUI
权利人:CHEMOURS CO FC LLC
摘要:A method of synthesizing 2,3,3,3-tetrafluoropropene (1234yf) from 2-chloro-3,3,3-trifluoropropene (1233xf). The 2-chloro-3,3,3-trifluoropropene (1233xf) is reacted in the vapor phase, in the presence of a catalyst, at a temperature and pressure sufficient to selectively convert the 2-chloro-3,3,3-trifluoropropene (1233xf) to 2,3,3,3-tetrafluoropropene (1234yf) without the use of antimony-based catalysts.

发明人：DESIMONE JOSEPH M; NI YIZENG
权利人:UNIV NORTH CAROLINA
摘要:A method of forming an electrically conductive polymer comprises providing a reaction mixture in carbon dioxide, the reaction mixture comprising at least one monomer and a charge transfer agent. The monomer is then polymerized in the carbon dioxide to form a polymer, and the polymer is doped with the charge transfer agent so that the polymer is an electrically conductive polymer.
