In ion pairs formed between organoruthenium complexes ( ̄uorophore) and triphenylmethane dyes (absorber), a deprotonation of the absorber leads to an absorbance band which overlaps the emission of the ̄uorophore whereby both the ̄uorescence intensity and the ̄uorescence lifetime of the ̄uorophore are altered.. Dissolving these ion pairs in polymer materials such as poly (vinyl chloride) or porous glass obtained by the sol±gel process results in membranes which respond to ammonia. Article Title: Coupling of biocatalytic asymmetric epoxidation with NADH regeneration in organic-aqueous emulsions. Article Snippet: The pivotal role of chiral oxyfunctionalized hydrocarbons as building blocks for pharmaceuticals or agrochemicals has driven the research for effective methods to obtain them in enantiopure form.. Over the past few decades, numerous chemical routes have been developed for catalytic asymmetric epoxidations.. 2] Amongst them, chiral salen–Mn complexes and metalloporphyrins have emerged as efficient catalysts for syntheses of optically active epoxides.

Article Title: Interaction of class III cellobiose dehydrogenase with lytic polysaccharide monooxygenase Article Snippet: Buffer components and chemicals employed in this study were purchased at the highest available purity from Sigma (now Merck, Darmstadt, Germany), Fluka (Buchs, Switzerland), Roth (Karlsruhe, Germany), or VWR (Radnor, PA, USA). Article Title: Formation of insoluble particulates in a spray-dried F(ab')(2) fragment. Article Snippet: An F(ab’)2 fragment of an IgG has been spray-dried on a bench-top machine to examine the presence of insoluble particulates in the redissolved powder product.. Preliminary experiments showed that treatment of the F(ab’)2 in aqueous solution in a water bath at 65◦C for 1 h produced fragmentation and also insoluble particulates, but no alteration in soluble aggregates.. On spray drying, there was, however, no fragmentation but rather formation of soluble aggregates and insoluble particulates. Article Title: Disposable microfluidic ELISA for the rapid determination of folic acid content in food products. Article Snippet: A micro-analytical system for rapid and quantitative analysis by inhibition immunoassay is presented and applied to the detection of folic acid.. Eight polymer microchannels of 65-nL volume each and containing microelectrodes are embedded in a cartridge so that they can be operated simultaneously.. All fluidic steps as well as the amperometric detection in the channels are operated by an instrument and software developed in-house. Article Title: Selective optical sensing of copper(II) ions based on a novel cyclobutane-substituted Schiff base ligand embedded in polymer films Article Snippet: The paper reports on the spectral photophysical characteristics of a novel fluorescent Schiff base ligand 4-(1-phenyl-1-methylcyclobutyl-3-yl)-2-(2-hydroxy-1-naphtylidene) thiazole (LH) in solvents of ethanol (EtOH), tetrahydrofuran (THF), and chloroform (TCM) and in solid matrix of polyvinyl chloride (PVC).. The LH dye embedded in plasticized PVC matrix has been used for preparing an optical sensor for Cu(II).. The response of the sensor is based on the fluorescence quenching of LH by Cu(II) ions. Thin Layer Chromatography:Article Title: The effect of electrolyte on the encapsulation efficiency of vesicles formed by the nonionic surfactant, 2C18E12. Article Snippet: Encapsulation efficiencies of vesicles formed by the nonionic surfactant 1,2-dioctadecyl-rac-glycerol-3-ω-methoxydodecylethylene glycol (abbreviated as 2C18E12) and its phospholipid counterpart, distearoylphosphatidylcholine (DSPC) at 298 K, were determined by the entrapment of the water-soluble dye, carboxyfluorescein (CF) to be 0.045 ± 0.001 and 0.03 ± 0.04 L mol−1 for 2C18E12 vesicles prepared using low osmolarity (270 m Osm) Krebs–Henseleit (K–H) buffer and a modified ‘high salt’ (1600 m Osm) variant of K–H buffer, respectively, and 0.64 ± 0.01 and 0.31 ± 0.04 L mol−1 for DSPC vesicles prepared under the same conditions and in the same buffers.. Freeze fracture electron microscopy studies confirmed the presence of vesicles when 2C18E12 and DSPC were dispersed in water and both buffer solutions.. Small angle neutron scattering (SANS) studies, using D2O in place of H2O, showed that when 2C18E12 vesicles were prepared in the ‘high salt’ variant of K–H buffer as opposed to K–H buffer or water, a higher proportion of multilamellar vesicles (MLV) were formed. |
