Migration mechanisms of gold nanoparticles explored in geogas of the Hetai ore district, southern China
geogas gold concelead ores gas migration
2017/4/12
Several studies have shown that gas flows (namely “geogas”) ascending from the Earth’s interior can, while passing
through concelead orebodies, assimilate ore nanoparticles and carry them to the surf...
Evaluation of Gas Transport Properties of Backfill Materials for Waste Disposal: H2 Migration Experiments in Compacted Fo-Ca Clay
Density Fo-Ca Clay Gas Critical and Breakthrough Pressures Gas Preferential Pathways H2 Migration Water Saturation Degree

Abstracts: Swelling clays may play a major role in the underground disposal of high-level nuclear waste (HLW) in deep geological formations. A multibarrier concept including a waste container, a steel...
Migration of Cations in Copper(II)-Exchanged Montmorillonite and Laponite upon Heating
CEC Measurements Cu-Laponite Cu-Montmorillonite EPR Hofmann-Klemen Effect IR XPS
2011/12/22
Abstract: Two clay minerals, a dioctahedral, Na-montmorillonite from Wyoming and a trioctahedral, synthetic Na-laponite, were exchanged by cupric (Cu(II)) ions and subsequently heated at 100 °C interv...

Abstract: When Li-saturated montmorillonite is heated to 200?00 癈, the Li ions migrate from interlayer positions to sites in the layer structure. However, the identity of these sites has not been clea...
Migration of Cu Ions in Cu Montmorillonite Heated With and Without Alkali Halides
Cu-montmorillonite K-halide IR and ESR spectra
2011/12/28
Cu montmorillonite heated with or without potassium halide was studied by IR and ESR spectroscopy, supplemented by XRD measurements, microprobe and chemical analyses. It appears that on heating Cu mon...
Cation Migration in Smectite Minerals: Electron Spin Resonance of Exchanged Fe3+ Probes
Electron spin resonance Hofmann-Klemen effect Ion migration Iron Laponite Montmorillonite Mossbauer spectroscopy
2012/1/5
The migration of interlayer Fe3+ cations into the structure of heated montmorillonite and Laponite has been studied by electron spin resonance (ESR), M鰏sbauer spectroscopy, and magnetic susceptibility...
Cation Migration into Empty Octahedral Sites and Surface Properties of Clays
Cation Migration Empty Octahedral Sites Surface Properties Clays
2012/2/20
The migration of small cations into the empty octahedral sites of dioctahedral clays allows one to study the local effects in the trioctahedral structure and the consequences of the exchange capacity ...
