Solvents are widely used in chemical processes. The use of efficient model-based solvent selection techniques is an option worth considering for rapid identification of candidates with better economic...
Direct pyrolysis of polymer nanospheres usually leads to severe particle aggregation, uncontrolled surface morphology, and poor solvent dispersibility of the carbonaceous analogues. The successful man...
We synthesized three types of magnetic iron oxide nanoparticles (MNPs), which were meso-2,3- dimercaptosuccinic acid (DMSA) coated MNPs (DMSA@MNPs, 17.3±4.8 nm, negative charge), chitosan (CS) coated...
A simplified nanosphere lithography process has been developed which allows fast and low-waste maskings of Si surfaces for subsequent reactive ion etching (RIE) texturing. Initially, a positive surfac...
Abstract: The surface charge components of 2 Georgia kaolinites of differing degrees of crystallinity (KGa-1 and KGa-2) were determined using procedures based on charge balance concepts. Permanent str...
Noncrystalline aluminosilicates termed allophane and imogolite are common constituents of spodosols, soils derived from volcanic ash, and many inceptisols. The surface charge characteristics of their ...
A critical demand in environmental modeling and a desirable but elusive goal of research on the ion exchange properties of the charged solid surface has been to determine the selectivity coefficient f...

The level of adsorption of enantiomeric tris(2,2′-bipyridyl)ruthenium(II) (Ru(bpy)32+ by seven different smectite samples was found to be controlled by the total surface area of the clay. The level co...
The effect of Fe oxidation state on the surface charge (CEC) and solubility of smectites were studied using the <2-祄, Na+-saturated fraction of an Upton, Wyoming; a Czechoslovakian; and a New Zealand ...
The surface and charge characteristics of 6 allophanic clays originating from a climatosequence of Andisols have been studied by titration, ion retention, surface area, and reactivity measurements. Se...
The surface charge characteristics of a range of synthetic amorphous aluminosilicates, hydrous alumina, hydrous silica and two allophanic soil clays were determined by the retention of Na+ and Cl as c...
The surface charge density of mica (001) cleavages was determined by counting the number of fission particle tracks in a given area of a 6-mm muscovite disc replica with optical and scanning electron ...
The variation with time of exchangeable surface charge of amorphous ferric hydroxide in aqueous suspension was monitored by a titration technique. After 120 days, the surface charge of suspensions wit...
Diquat2+ (1,1′-ethylene-2,2′-dipyridinium ion) and paraquat2+ (1,1′-dimethyl-4,4′-dipyridinium ion) were competitively adsorbed by Na-saturated kaolinites, smectites and expanded and collapsed vermicu...
