Measured long-ranged attractive interaction between charged polystyrene latex spheres at a water-air interface
(Physical Review E, 2006-08-15)
We report results of a systematic experimental study of interactions between charged polystyrene (PS) latex spheres at a water-air interface. Optical observations of stable bonded particle clusters and formation of circular ...
Survey of alkyl methacrylate latexes as aqueous catalytic media
Cationic polymer latexes serve as catalytic media for the hydrolysis of p-nitrophenyl esters by providing a more lipophilic environment into which these compounds can partition from the aqueous phase. The latex quaternary ...
Triethyl-n-hexylammonium triethyl-n-hexylboride: a new antimicrobial showing activity against Candida albicans and gram-positive bacteria
(Antimicrobial Agents and Chemotherapy, 1975-10)
The organic salt triethyl-n-hexylammonium triethyl-n-hexylboride (N2226 B2226) has biostatic effects against two gram-positive bacteria, Bacillus subtilis and Micrococcus luteus, and the yeast Candida albicans. Escherichia ...
Multilayer formation in an azacrown N6 Langmuir film
(Chemical Communications, 1998-01-01)
A neutron reflectivity study of a deuterated azacrown N6 at the air-water interface shows that it forms multilayers upon compression, with monolayers and trilayers being more stable than bilayers.
Donor-acceptor nanoensembles of soluble carbon nanotubes
(Chemical Communications, 2004-08-10)
Donor�acceptor nanoensembles, prepared via electrostatic interactions of single wall carbon nanotubes and porphyrin salts, give rise to photoinduced intra-complex charge separation that lasts tens of microseconds.
Autoxidation of tetralin in water catalysed by Cobalt(ii)-pyridine complexes bound to polymer colloids
(Chemical Communications, 1988-01-01)
Cobalt(ii)-pyridine complexes bound to 60 nm diameter latex copolymers of styrene, divinylbenzene, and either acrylic or methacrylic acid catalyse autoxidation of tetralin in water faster than cobalt(ii)-pyridine complexes ...
Long-ranged attraction between charged polystyrene spheres at aqueous interfaces
(Physical Review Letters, 2005-11-15)
We report an optical and atomic force microscopic study of interactions between charged polystyrene spheres at a water-air interface. Optical observations of bonded particle clusters and formation of circular chainlike ...
XANES and EXAFS study of a platinum phthalocyanine
(Chemical Communications, 1994-01-01)
Extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) studies on [octa(2-ethylhexyloxy)phthalocyaninato]platinum [PtL] as a film at room temperature suggest that the structure ...
