Abstract Synthesis of proton-conducting materials based on track-etched membranes from polyvinylidene fluoride and sulfonated cross-linked polystyrene is described. The synthesis has been carried out by filling the pores original or gamma-irradiated membrane copolymerization styrene/divinylbenzene followed sulfonation with chlorosulfonic acid. resulting have studied scanning electron microscopy...
A solid-phase microextraction (SPME) method for the simultaneous determination of a large number of pesticides (46) with a wide range of polarities and chemical structures (organochlorine, organophosphorous, triazines, pyrethroids and others) in water samples by GC-MS has been developed. Three different fibres and parameters that influence the extraction and desorption efficiency were studied. ...
Heparin, in Langmuirian fashion, binds stoichiometrically with high affinity, Kd approximately 100 nM, to both fibrinogen and fibrin adsorbed as monomolecular films to lecithin-coated, microscopic, polystyrene-divinylbenzene beads. Complex formation inhibits aggregation of fibrin-coated beads, and it also results in dissociation of preformed aggregates of fibrin-coated beads. These phenomena ar...
This study focuses on the chemistry, thermal stability, and electrical conductivity of low/intermediate pyrolysis temperature (700?900 °C) polysiloxane derived ceramics. These ceramics were modified with additional carbon from divinylbenzene (DVB) added to precursor. Their properties investigated for potential uses in micro-electrical mechanical systems (MEMS) anodes lithium batteries. The micr...
Front Cover: In article number 2100022 by Tugrul Cem Bicak, a new method, namely “Type-II photoinitiated precipitation polymerisation”, is described for the synthesis and functionalisation of highly crosslinked microspheres in one step. Using this click functionality introduced to particles at room temperature UV irradiation. A pyrene group then attached onto CuAAC reaction confirm presence acc...
A rapid and automated solid phase microextraction (SPME) stable isotope dilution gas chromatography/mass spectrometry (GC-MS) method for 2-methoxy-3-isobutylpyrazine (MIBP) quantification in red wine was developed. Wines with 30% (w/v) NaCl and 2-methoxy-(2)H(3)-3-isobutylpyrazine internal standard were sampled with a 2 cm divinylbenzene/carboxen/poly(dimethylsiloxane) SPME fiber for 30 min at ...
