A series of novel superabsorbent composites guar gum-g-poly(sodium acrylate-co-styrene)/vermiculite (GG-g-poly(NaAco-St)/VMT) were prepared by the simultaneous graft copolymerization of guar gum (GG),...
A series of novel superabsorbent nanocomposites were prepared by the solution radical polymerization of natural guar gum (GG), partially neutralized acrylic acid [sodium acrylate (NaA)], and cationex...
A series of hydroxyethyl cellulose-g-poly(acrylic acid)/vermiculite (HEC-g-PAA/VMT) superabsorbent nanocomposites were prepared by radical solution polymerization among hydroxyethyl cellulose (HEC), p...
In this study, a series of chitosan-g-poly(acrylic acid)/vermiculite (CTS-g-PAA/VMT) superabsorbent composites containing VMT, acid-activated,ion-exchanged, and organic modified VMT were synthesized b...
Vermiculite (VMT) was modified with cetyl trimethylammonium bromide (CTAB). Superabsorbent nanocomposites were prepared by solution polymerization of natural guar gum (GG), partially neutralized acryl...
Abstract: Coarse-grained vermiculite from a serpentinite-pegmatite thermal zone displays a rational series of narrow 14.4 ∈ basal reflections and an unusual broad 28 ∈ peak. X-ray diffraction simulati...
Abstract: A nickel hydroxide-vermiculite complex (NHVC) with csinβ = 1.41 nm and particle sizes from 0.075 to 0.15 mm was obtained hydrothermally by adding nickel nitrate solution to vermiculite from ...
Abstract: The sorption of the uranyl oxo-cation (UO22+)at different types of binding sites on layer silicate mineral surfaces was investigated. Well-characterized samples of vermiculite and hydrobioti...
Abstract: Vermiculite from Santa Olalla, Spain, was intercalated with tetramethylphosphonium [P(CH3)4+ = TMP], using a TMP-bromide solution at 70∑C for three weeks. The resulting TMP-exchanged vermicu...
Abstract: The structure of the interlayer cation-water system in La-vermiculite with a unit cell of a = 5.33(5), b = 9.18(6), c = 15.13(9) 侌 and 兝 = 96.82(7)亱 has been determined in space group C2/m. ...
Abstract: Interaction between n-butylammonium (BA) chloride and vermiculite from Santa Olalla (Spain) has been studied in large flake (5 × 5 × 0.1 mm) or ground powder (≤80 µm) samples. The diff...
Atomic-resolution transmission electron microscope (TEM) images reveal that IIbb( b5 978 ) Mg,Al,Fe-chlorite from Koongarra, Australia, transforms to vermiculite via a range of intermediate chemical a...
Abstract: The acidic properties of acid-modified montmorillonite and vermiculite were determined by pyridine and ammonia adsorption to correlate with the alkylating and dehydrating activity of the act...
Abstract: Vermiculite crystals from Santa Olalla, Spain, were intercalated with tetramethylammonium (TMA) after Na saturation. The resulting TMA-vermiculite showed near perfect 3-dimensional stacking ...
Abstract: A 4-component clay-polymer-salt-water system was studied by neutron scattering. The clay-salt-water system consisted of n-butylammonium vermiculite, n-butylammonium chloride and heavy water,...
