Surface Chemistry of Soil Minerals
TL;DR: In this paper, the nature of constant-charge and pH-dependent-charge colloidal surfaces, using descriptions based on models and direct spectroscopic investigations, is discussed, including cation exchange, the chemisorption of cations and anions on oxides, and electron and proton transfer reactions.
Journal ArticleDOI
Vermiculite decorated with copper nanoparticles: Novel antibacterial hybrid material
TL;DR: Vermiculite decorated with copper nanoparticles is a new antibacterial material that was prepared in this study through ion-exchange process and hydrogen reduction as discussed by the authors, the replacement of magnesium ions in interlayer structure was carried out using concentrated copper sulfate solutions at elevated temperature.
Journal ArticleDOI
Effects of temperature on the sorption of lanthanides by montmorillonite
TL;DR: The diffusion of exchanged Yb, Ho, and Eu from interlayer positions in montmorillonite was studied using infrared spectroscopy (IR), X-ray powder diffraction, and cation-exchange measurements.
Journal ArticleDOI
Polarized XANES and EXAFS spectroscopic investigation into copper(II) complexes on vermiculite
TL;DR: In this article, the authors used powder and polarized extended X-ray absorption fine structure (EXAFS) spectroscopy and near-edge spectrograms (XANES) to investigate Cu sorbed on Llano vermiculite and compare the results to reported Cu sorption mechanism on Wyoming (WY) smectite and reduced South African (SA) vermiculate.

Electron paramagnetic resonance spectroscopy
B. A. Goodman,P. L. Hall +1 more
TL;DR: In this article, the authors used paramagnetic resonance (EPR) spectroscopy for the detection of unpaired electrons and with characterizing their chemical environments, which is able to provide information on materials in both liquid and solid phases.

ESR Studies on the Bonding in Copper Complexes
Daniel Kivelson,Robert Neiman +1 more
TL;DR: In this paper, the in-plane π bonding may be as important in determining the properties of a Cu complex as is the inplane σ bonding, and the relationship between π and σ has been investigated.

Interlayer complexes in layer silicates. The structure of water in lamellar ionic solutions
V. C. Farmer,J. D. Russell +1 more
TL;DR: In this article, the stretching vibrations of water in montmorillonite, hectorite, saponite and vermiculite are split into two components, similar to those seen in perchlorate solutions.

ESR and NMR in Aqueous and Methanol Solutions of Copper(II) Solvates. Temperature and Magnetic Field Dependence of Electron and Nuclear Spin Relaxation
Raphy Poupko,Zeev Luz +1 more
TL;DR: In this paper, the ESR line-shape measurements of Cu(ClO4)2 solutions in methanol and water at X and Q-band frequencies are reported, and the results are quantitatively interpreted in terms of two main electronic relaxation mechanisms, viz., modulation of spin rotation and anisotropic g tensor interactions.
