We describe the preparation of a thermoresponsive microgel, which can non-covalently immobilize active proteins with enhanced biocatalytic performance in organic solvents and easy reusability due to the porous microstructure and temperature responsive property.

The temperature of spin-crossover in [Fe(3-bpp)(2)][BF(4)](2) (3-bpp = 2,6-di{pyrazol-3-yl}pyridine) tends to increase in associating solvents. In particular, T(½) shifts to 60-70 K higher temperature in water compared to organic solvents.

A self-assembled M(2)L(4) palladium-pyridyl cluster with a "paddle-wheel" structure shows binding affinity in competitive organic solvents for neutral organic guests that possess both the correct size and electrostatic complementarity.

This communication reports a new technology platform that advantageously combines organic solvent nanofiltration (a newly emerging technology capable of molecular separations in organic solvents) with solution phase peptide synthesis-Membrane Enhanced Peptide Synthesis (MEPS).

A gene encoding a novel organic solvent-tolerant alkaline lipase, lipS (GenBank ID JQ071496), was cloned from cold-adapted Pseudomonas mandelii. Recombinant LipS was expressed in Escherichia coli as a 32-kDa soluble protein and was purified by standard procedures. It maintained more than 80% of its activity under alkaline conditions, pH 8-10.5, with an apparent optimum temperature range of 40-5...

an ultrasound-assisted surfactant-enhanced emulsification microextra- ction (uaseme) coupled with high performance liquid chromatography-diode array detection has been developed for the extraction and determination of thiopental in serum and urine samples. a simple microextraction method based on emulsification of organic extraction solvent in aqueous sample using an ionic surfactant and withou...
