The results showed that ultrasonic amplitude of 50% and ultrasonic duration of 15min were the optimum conditions for the preparation of a mini-emulsion containing long alkyl chain monomer stearyl methacrylate (SMA). The ultimate conversion of monomers declined with increasing SMA, while the ...
Ketol-acid reductoisomerase (KARI, EC 1.1.1.86, gene: ilvC) converts the two respective intermediates into 2,3-dihydroxycar- boxylic acids by migration of an alkyl group followed by a reduction by nicotinamide adenine dinucleotide phosphate in its reduced form (NADPH). KARI also requires M...
Branched-chain fatty acids (BCFA) are a class of primarilySFAwith an alkyl group branch, usually methyl, on the carbon chain. Other alkyl groups are also feasible as the branch (e.g. ethyl,Fig. 2) but the predominant group is methyl. The branching predominantly occurs near the methyl end...

The data showed that some surfactants dramatically reduced the interfacial tension as well as the tension of oil/water interface to ...
The n-alkyl derivative of tetrakis(n-pentyldithiolato)dinickel(II), 1a, has a monotropic discotic lamellar (DL) phase, whereas the branched-chain-substituted derivative of tetrakis(1-ethylpentyldithiol-ato)dinickel(II), 1b, has both an enantiotropic discotic hexagonal disordered columnar (Dhd...
