Biosourced amphiphilic degradable elastomers of poly(glycerol sebacate): Synthesis and network and oligomer characterization
(2013)Glycerol (G, a triol) and sebacic acid (S, an α,ω-dicarboxylic acid) were condensed in the bulk to obtain poly(glycerol sebacate) (PGS) cross-linked elastomers which were characterized in terms of their swelling, thermal, ...

Cyclisation chemistry of 4H-1,2,6-thiadiazines
(2000)3,5-Dichloro-4H-1,2,6-thiadiazin-4-one 1 condenses rapidly at room temperature with 1,2-diaminobenzene, 2-aminothiophenol and sodium 2-aminophenoxide to give, respectively, the purple thiadiazinoquinoxaline 4a, red ...

Effects of hofmeister anions on DPPC langmuir monolayers at the air-water interface
(2004)In this work we investigated the effect of sodium salts of different monovalent anions belonging to the Hofmeister series on Langmuir monolayers of DPPC (1,2-dipalmitoyl phosphatidylcholine). The salts used were NaCl, NaBr, ...

Piecewise linear emulator of the nonlinear Schrödinger equation and the resulting analytic solutions for Bose-Einstein condensates
(2003)A most general method for finding very good analytic approximate solutions to the cubic nonlinear Schrodinger equation is presented. This method applies whenever the nonlinearity in that equation is a purely cubic one. It ...

Synthesis of [(4-Chloro-5H-1,2,3-dithiazol-5-ylidene)amino]azines
(2011)The reactions of 2-, 3- and 4-aminopyridines with 4,5-dichloro-1,2,3- dithiazolium chloride (Appel salt) 4 to give N-(4-chloro-5H-1,2,3-dithiazol-5- ylidene)pyridin-Xamines 1a (X = 2), 1g (X = 3) and 1k (X = 4) were optimized ...
