a liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for k ion in transport while diethylene glycol dibutyl ether (1) was selective for na over k . as an extractant, ligand 2 exhibited pronounced extraction selectivity for k over na in comparison with ligand 1
The synthesis of a biobased aliphatic polyester, poly (hexamethylene sebacate) (PE 6-10) via esterification and alcoholysis reaction steps by reactive extrusion is reported. overall time was decreased down to around 14 min instead roughly 360 in classical batch reactor. A number average molar mass 21,100 g.mol?1 has been reached. operating conditions were first optimized through reactors synthe...
Using a novel and highly selective technique, we measured monoester metabolites of seven commonly used phthalates in urine samples from a reference population of 289 adult humans. This analytical approach allowed us to directly measure the individual phthalate metabolites responsible for the animal reproductive and developmental toxicity while avoiding contamination from the ubiquitous parent c...
Bacteria of the genus Methylobacillus are methanotrophs, a metabolic feature that is widespread in the phylum Proteobacteria. The study demonstrates the isolation and characterization of a newly isolated Methylobacillus sp. V29b. which grows on methanol, protocatechuate, monobutyl phthalate, dibutyl phthalate, diethyl phthalate, benzyl butyl phthalate, dioctyl phthalate and diisodecyl phthalate...
Purpose: To develop transdermal patches of meloxicam (MLX) using chitosan and hydroxypropyl methylcellulose (HPMC) and polyvinyl alcohol (PVA) as hydrophilic polymers, polyamido amine (PAMAM) dendrimer as a permeation enhancer, and dibutyl pthalate as a plasticizer Methods: The patches were prepared by solvent casting evaporation technique using 3-factor, 3-level Box-Behnken design. The patches...
