Pure gas permeability coefficients of a series of copolymers based on polar, hydrophilic poly(ethylene glycol) dimethacrylate, n 1⁄4 14 (PEGDMA) and siloxane-based co-monomer, [methyl bis(trimethylsiloxy) silyl] propyl glycerol methacrylate (SiGMA) are reported. SiGMA is miscible with PEGDMA and able to form homogeneous films. SiGMA contains a bulky siloxane-based end group, which acts to incre...

we present observation of polar coronal hole plumes with foot point jets that shows evidence of longitudinal acceleration. the series of event, occurring in the north coronal hole on 10 july 2010, was observed by the aia telescopes of the solar dynamic observatory (sdo mission) in the euv lines, with unprecedented details. the structures along the plume show a propagating outward velocity of ab...

The synthesis of polar functionalized cyclic olefin copolymers (COCs) from the coordination copolymerization norbornene (NB) and monomers catalyzed by late transition metal catalysts has been a recent research hotspot. However, few have achieved efficient with commercial vinyl-type monomers, such as methyl acrylate (MA). In this contribution, nickel complexes bearing 2-(diarylphosphino)-N-pheny...

The pulsed laser polymerization-size-exclusion chromatography (PLP-SEC) technique has become the International Union of Pure and Applied Chemistry (IUPAC)-recommended method for accurate determination propagation rate coefficients, kp, radical polymerization. fundamental insight provided by Heuts, Gilbert, Radom into relevance transition state dynamics allows an adequate understanding dependenc...

[1] Recently proposed ion-mediated nucleation theory suggests that the enhanced uptake of neutral polar molecules by the charged clusters as a result of dipole-charge interaction may be critical to the nucleation of particles in the atmosphere. A rigorous parameterization of the enhancement effect of dipole-charge interaction on the growth of charged clusters is presented and the important para...
