Grafting of polymers onto a carbon black surface by the trapping of polymer radicals
(John Wiley & Sons, Ltd., 1998-10)
The grafting of polymers onto a carbon black surface based on the trapping of polymer radicals by polycondensed aromatic rings of the surface was investigated. It was found that polymer radicals formed by the thermal ...
Polyfunctional cubic silsesquioxanes as building blocks for organic/inorganic hybrids
(John Wiley & Sons, Ltd., 1998-10)
Cubic silsesquioxanes, [RSiO 1.5 ] x , potentially offer access to organic/inorganic hybrids wherein the exact shape, size and mechanical properties of the inorganic component are perfectly defined. Furthermore, by ...
Polymer-layered silicate nanocomposites: Synthesis, properties and applications
(John Wiley & Sons, Ltd., 1998-10)
Polymer nanocomposites, especially polymer-layered silicate (PLS) nanocomposites, represent a radical alternative to conventionally (macroscopically) filled polymers. Because of their nanometer-size dispersion, the ...
Probing the potential metal binding site in Escherichia coli 3‐deoxy‐d‐arabino‐heptulosonate 7‐phosphate synthase (phenylalanine‐sensitive)
(Wiley Periodicals, Inc., 1998-12-18)
Open pore biodegradable matrices formed with gas foaming
(John Wiley & Sons, Inc., 1998-12-05)
Engineering tissues utilizing biodegradable polymer matrices is a promising approach to the treatment of a number of diseases. However, processing techniques utilized to fabricate these matrices typically involve organic ...
Stability of the contractile assembly and Ca 2+ - activated tension in adenovirus infected adult cardiac myocytes
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-04)
Adenovirus-mediated gene transfer into adult cardiac myocytes in primary culture is a potentially useful method to study the structure and function of the contractile apparatus. However, the consequences of adenovirus ...
The influence of environment on the induction of sensitization to the psychomotor activating effects of intravenous cocaine in rats is dose-dependent
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-04)
The acute psychomotor response and development of sensitization to amphetamine is attenuated if IP injections are given in the cage where a rat lives relative to when injections are given in a novel but physically identical ...
Chemical vapor deposition of tungsten oxide
(John Wiley & Sons, Ltd., 1998-03)
Crystalline and amorphous thin films of tungsten(VI) oxide can be prepared by chemical vapor deposition using a variety of volatile precursors below 500 °C. Deposition parameters for preparation of WO 3 films from tungsten ...
Synthesis of poly(vinyl alcohol) / silica gel polymer hybrids by in-situ hydrolysis method
(John Wiley & Sons, Ltd., 1998-10)
Homogeneous poly(vinyl alcohol) (PVA)–silica gel polymer hybrids were prepared by in-situ hydrolysis of poly(vinyl acetate) (PVAc) in a sol–gel reaction mixture with tetramethoxysilane (TMOS). The degree of hydrolysis was ...
Rearrangements versus ligand exchange reactions of organocobalt polymer having cobaltacyclopentadiene moieties in the main chain Part of the work presented here was communicated in Ref. 1: Macromolecules , 27 , 7009 (1994).
(John Wiley & Sons, Ltd., 1998-10)
The rearrangement reaction of an organocobalt polymer with cobaltacyclopentadiene moieties in the main chain ( 1 ) was carried out to yield anew polymer bearing (η 5 -cyclopentadienyl) (η 4 -cyclobutadiene)cobalt moieties ...
