In 1998, there were many volcanic earthquakes recorded at Iwate volcano, Japan. Although an eruption was anticipated, it never occurred. Fumarolic gases were sampled at the volcano on six occasions du...
Organo-clay composites have potential applications in geosynthetic clay liners to provide protection against loss of the hydraulic barrier under hypersaline conditions (Gates, 2004). It has been repor...
Halloysite is a tubular or hollow cylinder shaped clay and is commonly known as halloysite nanotubes (HNTs) which has a chemical formula of Al2(OH)4Si2O5.2H2O similar to kaolinite (Joussein et al., 20...
Stable leather superfine powder suspension was got by superfine powder of leather solid wastes, maleic anhydride(MAH) and acrylic acid(AA). The best MAH、AA modifying conditions with grafting ratio as ...
This paper was prepared by liquid phase deposition of quartz sand load nanometer titanium dioxide film, in which quartz sand as the carrier, and to Fe3+,Zn2+ as doping on the membrane was modified. Th...
Collagen was immobilized onto moderate acid activated polyamide fibers with glutaraldehyde (cross-linking agent) aimed to improve its sanitary property. The immobilization of collagen onto polyamide f...
In order to explore the proper modified materials of the raw-soil building in mountain area, the raw-soil modified materials now being used commonly are analyzed effectively at first, and the natural ...
Attapulgite was organic surface modified with silane coupling agent (KH570) and acetone, with ferric chloride (FeCl3∙6H2O) as the oxidant, sulfamic acid(SA) as dopant, prepared polypyrrole/attap...
This contribution explores the interaction of the fibrous silicates, palygorskite, sepiolite and chrysotile with a wide range of organic agents. Infrared spectroscopy (IR) methods are essential for th...
Abstract: X-ray powder diffraction (XRD), thermal gravimetric analysis (TGA), surface area measurements, and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy were used to examine the su...
Abstract: In the search for new applications of natural silicates, various F− treatments have been applied to sepiolite to increase its acidic properties and for use as a catalyst in reactions o...
The crystal structure of a synthetic NaAlSiO4 modification has been solved and refined to an R index of 0.020 for 2745 independent reflections. The compound is hexagonal with space group symmetry P 6 ...
Metapelitic rocks from a progressive metamorphic sequence in Dutchess County, New York,record evidence for reaction between garnet and fluids associated withquartz (::!:pla-gioclase) veins and for net...
The electrochemical properties of kaolinite before and after modification with chlorodimethyl-octadecylsilane have been studied by electrophoretic mobility, surface charge titration, and extrapolated ...
Modifications of the external surface area and the two types of microporosity of sepiolite (structural microporosity and inter-fiber porosity) were examined as a function of the temperature of a vacuu...
