Characterization of Silanol Groups in Protonated Magadiite by 1H and 2H Solid-State Nuclear Magnetic Resonance
1H NMR 2H NMR Hydrogen Bonding Magadiite Silanol Group
2011/12/6
Abstract: Silanol groups in protonated magadiite (H-magadiite) were characterized by 1H and 2H solid-state nuclear magnetic resonance (NMR). H-magadiite and deuterated (D) magadiite were synthesized b...
Effects of Clay Fraction and Temperature on the H2O Self-Diffusivity in Hectorite Gel: A Pulsed-Field-Gradient Spin-Echo Nuclear Magnetic Resonance Study
Complexity of Pore Structure Hectorite H2O NMR Self-Diffusion
2011/12/6
Abstract: Self-diffusion coefficients of H2O molecules in Na-rich hectorite gel were measured by 1H nuclear magnetic resonance (NMR). Spin-echo pulse sequences with magnetic field gradient pulses for ...
A Nuclear Magnetic Resonance (NMR) and Fourier-Transform Infrared (FTIR) Study of Glycine Speciation on a Cd-Rich Montmorillonite
Adsorption Amino Acids Cadmium Glycine Montmorillonite Speciation
2011/12/6
Abstract: As a consequence of treatments with glycine solutions, glycine molecules enter the interlayer of both Ca- and Cd-rich montmorillonite. Measurements of d value suggest that at low glycine con...
Nuclear Magnetic Resonance (NMR) Study of Cd2+ Sorption on Montmorillonite
Adsorption Cadmium Montmorillonite Nuclear Magnetic Resonance
2011/12/8
Abstract: 113Cd solid-state nuclear magnetic resonance (NMR) was used to identify possible Cd2+ adsorption sites in montmorillonite. The montmorillonite was treated with 0.1 and 1 M CdCl2 aqueous solu...
Reactive Al-O-Al sites in a natural zeolite: Triple-quantum oxygen-17 nuclear magnetic resonance
Reactive Al-O-Al sites natural zeolite Triple-quantum oxygen-17 nuclear magnetic resonance
2012/4/1
In framework aluminosilicate materials (e.g., feldspars, zeolites and many others), it is generallyassumed that AlOtetrahedra do not share corners, i.e., that Al-O-Al oxygen sites are avoided whenstoi...
