Synthesis and characterization of complexes between poly(itaconic acid) and poly(ethylene glycol)
(Springer, New York, 2004)
Interpolymer complexes of poly(itaconic acid) and poly(ethylene glycol) (PIA/PEG) were prepared by two different procedures: simple mixing of preformed PIA and PEG and by polymerization of itaconic acid on poly(ethylene ...
Metal sorption on macroporous poly(GMA-co-EGDMA) modified with ethylene diamine
(Elsevier Science Bv, Amsterdam, 2004)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and modified by ...
Surface characterization and properties of keratin fibers treated with low-temperature plasmas
(Polymer Surface Modification: Relevance to Adhesion, Volume 3, 2004)
The relation between shrink-resistance properties and surface changes (wettability, atomic chemical composition and topographical or morphological) induced by low-temperature plasmas (LTPs) has been studied in depth. For ...
Thermal behaviour of mixed ligand Co(II), Ni(II) and Cu(II) complexes containing terephthalate ligands
(Elsevier, Amsterdam, 2004)
Thermal behaviour of a series of ternary Co(II), Ni(II) and Cu(II) complexes with terephthalate ion and some aromatic diamines has been studied by thermogravimetric and differential scanning calorimetric techniques. ...
Principal component analysis of trace elements in industrial soils
(Springer Heidelberg, Heidelberg, 2004)
The concentrations of the elements Cr, Pb, Cd, Zn, Ni, Mn, Cu and As in soil samples from industrial areas in Serbia were studied. The complexity of the data of eight elements in fifty-nine soil samples was reduced by ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Thermodynamic modeling of vapor-liquid equilibria and excess properties of the binary systems containing diethers and n-alkanes by cubic equation of state
(Korean Institute Chemical Engineers, Seoul, 2004)
A comparison of the performances of two different approaches of cubic equations of state models, based on a classical van der Waals and mixing rules incorporating the G(E) equation, was carried out for correlation of ...
Poly(acrylamide-co-itaconic acid) and semi-IPNS with poly(ethylene glycol): Preparation and characterization
(Wiley-VCH Verlag Gmbh, Weinheim, 2004)
A pH-responsive poly(acrylamide-co-itaconic acid) (PAAm/IA) hydrogel and semi-interpenetrating networks (semi-IPNs) with 5, 10 and 15 wt.-% of poly(ethylene glycol) (PAAm/IA/PEG), were synthesized. Their swelling behavior ...
Aspirin polyrnorphs, exist or not?
(Elsevier, Amsterdam, 2004)
Characterization and antimicrobial activity of bacteriocin 217 produced by natural isolate Lactobacillus paracasei subsp paracasei BGBUK2-16
(Int Assoc Food Protection, Des Moines, 2004)
The strain Lactobacillus paracasei subsp. paracasei BGBUK2-16, which was isolated from traditionally homemade white-pickled cheese, produces bacteriocin 217 (Bac217; similar to7 kDa). The onset of Bac217 biosynthesis was ...
