Ethylene oxide-based glycol ether and glycol ether ester solvents have been used in the coatings industry for the past fifty years. Because of their excellent performance properties (evaporation rate, blush resistance, flow-out and leveling properties, solubility for coating resins, solvent activity, mild odor, good coupling ability, good solvent release) a complete line of ethylene oxide-based...

A gas chromatography/mass spectrometric assay method has been developed for the simultaneous determination of icing inhibitors, ethylene glycol monomethyl ether and diethylene glycol monomethyl ether in ground water contaminated with JP-8. Ethylene glycol monobutyl ether and ethylene glycol monoethyl ether were used as the internal standard and surrogate, respectively. 100 mL of ground water wa...

Starch nanoparticles (SNPs) useful for the extraction of bitumen from oil sands were obtained by modification with thermoresponsive poly(di(ethylene glycol) methyl ether methacrylate) (PMEO2MA) segments through RAFT (Reversible Addition–Fragmentation chain Transfer) grafting. Since PMEO2MA exhibits a Lower Critical Aggregation Temperature (LCAT), polymer-grafted SNPs are amphiphilic above LCAT ...

Novel pH-sensitive gel-forming pentablock copolymers based on commercially available Pluronic (poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide), PEO-b-PPO-b-PEO) triblock copolymers and cationic diblock copolymers based on polyethylene glycol) methyl ether (PEGME) were synthesized by oxyanionic polymerization. Polymerization of the cationic moiety, poly((diethylamino)-ethyl m...

Poly(ethylene glycol) (PEG)-based soft elastomers, bearing tertiary amine and hydroxyl groups, were synthesized in bulk from the epoxy–amine reaction between poly(ethylene diglycidyl ether (PEGDE) a poly(etherdiamine), Jeffamine ED600. High gel fractions (≥0.95) low glass transition temperatures (Tg ≈ −50 °C) attained after complete curing of systems bulk. The amphiphilicity network allowed swe...

A recently reported “plug-n-play” approach to simplified electrochemical atom transfer radical polymerization (seATRP) is investigated using machine learning. It shown that Bayesian optimization via an active learning (AL) algorithm accelerates of the oligo(ethylene glycol methyl ether acrylate)480 (OEGA480) in water. Molecular weight distribution (Mw/Mn; dispersity; Ɖm) output selected for tar...

In this study, we identify 11 mouse pup volatiles putatively involved in maternal care induction adult females. For purpose, have adapted the dynamic headspace methodology to extract volatolome of whole alive animals. Untargeted metabolomic was used compare neonatal (4–6 days) with elder pups until age weaning (21–23 days old). Pup analyzed by gas chromatography (GC) coupled single quadrupole m...

Three-dimensional silicon carbide-based frameworks with hierarchical micro-, meso-, and macroporous structures (3MPSiC) were prepared by a template method with subsequent carbonization via an aerosol spray drying method. The micropores were derived from partial vaporization of Si atoms during the carbonization process, whereas the meso- and macropores were generated by self-assembly of the stru...

In this work, the copolymer-based synthesized Cysteine-loaded nanocarriers prepared by a routine protocol, coprecipitation method. It is the first report to investigate the neuroprotective potential and biocompatibility of Cysteine derivatives loaded into poly(ethylene glycol)-block-poly(ε−caprolactone) methyl ether (PEG-b-PCL). The average size of the polymeric/empty NCs was 89 nm and for poly...

in this work, poly (o-anisidine) (poa) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of carbon paste electrode (cpe). nickel ions were dispersed into the polymer by immersing the electrode in niso4 solution. the prepared ni/poa/cpe was characterized by scanning electron microscopy, energy dispersive x-ray spectroscopy, atomic force microscopy (afm) a...
