Polymers and inorganics: A happy marriage?
The most recent developments in two areas: (a) synthesis of inorganic particles with control over size and shape by polymer additives, and (b) synthesis of inorganic-polymer hybrid materials by bulk polymerization of blends ...
Tailored CeO2 nanoparticles surface in free radical bulk polymerization of methyl methacrylate
(American Chemical Society, 2013-09)
Polymerization of monomer/nanoparticle dispersion, namely in situ polymerization, has been frequently used for the fabrication of polymer nanocomposites. However, the interference of nanoparticle surface with polymerization ...
Characterization of the uptake of aqueous Ni2+ ions on nanoparticles of zero-valent iron (nZVI)
This study investigates the fixation of aqueous Ni2+ ions by nanoparticles of zero-valent iron (nZVI) prepared using the borohydride reduction method. The uptake of Ni2+ was tested under various experimental conditions ...
Retention of aqueous Ba2+ ions by calcite and aragonite over a wide range of concentrations: Characterization of the uptake capacity, and kinetics of sorption and precipitate formation
(The Geochemical Society of Japan, 2007)
The uptake of aqueous Ba2+, ions by abiogenic calcite and aragonite was studied over a wide range of concentration; 1.0 × 101, 5.0 × 101, 1.0 × 102 5.0 × 102, 1.0 × 103, 5.0 × 104, and 1.0 × 104 mg/L. The uptake process ...
A new methodology for removal of boron from water by coal and fly ash
High levels of boron concentrations in water present a serious problem for domestic and agriculture utilizations. The recent EU drinking water directive defines an upper limit of 1 mgB/I. In addition, most crops are sensitive ...
Rhodium-catalyzed carbonylative arylation of alkynes with arylboronic acids: An efficient and straightforward method in the synthesis of 5-aryl-2(5H)-furanones
(Royal Society of Chemistry, 2006)
5-Aryl-2(5H)-furanones can be synthesized by the Rh-catalyzed reactions of arylboronic acids with internal alkynes under a CO atmosphere.
Controlled Formation of the Two-Dimensional TTBC J-Aggregates in an Aqueous Solution
(American Chemical Society, 2013-09-30)
Strong experimental and theoretical evidence was provided on the controlled formation of the two-dimensional J-aggregates that were assembled in the herringbone morphology. The exciton-band structure formation of ...
Chitosan-immobilized pumice for the removal of As(V) from waters
A novel sorbent, chitosan-immobilized pumice, has been prepared for the sorption of As(V) from waters prior to its determination by hydride generation atomic absorption spectrometry. The success of the immobilization has ...
Speciation and preconcentration of inorganic tellurium from waters using a mercaptosilica microcolumn and determination by hydride generation atomic absorption spectrometry
(Royal Society of Chemistry, 2000-11-23)
A separation–preconcentration method utilising a mercapto-modified silica microcolumn was developed for the determination of trace amounts of Te(IV) and Te(VI) in waters by hydride generation atomic absorption spectrometry. ...
Optical transition rates of a meso-substituted thiacarbocyanine in methanol-in-oil reverse micelles
We report the photophysical properties of 3,3′-diethyl-5,5′-dichloro-9-phenylthiacarbocyanine (DDPT) in methanol-in-oil (m/o) reverse micellar systems which form methanol droplets stabilized with anionic surfactant aerosol-OT ...
