The N M R spectroscopy of molecules undergoing rapid exchange between diamagnetic and paramagnetic environments is well understood and is exemplified in studies of fast electron transfer between an or...
The Surface Nuclear Magnetic Resonance (SNMR) method is a fairly new technique in geophysics to assess ground water, i.e. existence, amount and productibility by measurements at the surface. The NMR t...
Abstract: We investigate nuclear magnetic resonance (NMR) in near-zero-field, where the Zeeman interaction can be treated as a perturbation to the electron mediated scalar interaction (J-coupling). Th...
We report a 23Na and 75As nuclear magnetic resonance (NMR) investigation of NaxFeAs series (x = 1, 0.9, 0.8) exhibiting a spin-density wave (SDW) order below TSDW = 45, 50 and 43 K for x = 1, 0.9, 0...
The critical doping levels in cuprates, where the ground state changes its nature (from an an- tiferromagnet to a spin glass to superconductor to metal), are not universal. We investigate the origin ...
“Symposium of Nuclear Magnetic Resonance for Biological Macromolecules, 2009” will be held from June 25th to June 29th, 2008 in the city of Hefei, Anhui, P. R. China, organized by University of Scienc...

To correctly invert and interpret Surface Nuclear Magnetic Resonance (SNMR) data collected in conductive terrains, an accurate estimate of subsurface conductivity structure is required. Given such an ...
May 15, 2007,Detecting the molecular structure of a tiny protein using nuclear magnetic resonance (NMR) currently requires two things: a million-dollar machine the size of a massive SUV, and a large s...
The composition and abundance of phosphorus extracted by NaOH-ethylenediaminetetraacetic acid from anoxic Northwest Baltic Sea sediment was characterized and quantified using solution 31P nuclear magn...
We discuss the applications of Nuclear Magnetic Resonance (NMR) to quantum information processing, focusing on the use of quadrupole nuclei for quantum computing. Various examples of experimental impl...
Noninvasive 1 H–nuclear magnetic resonance (NMR) imaging was used to investigate the diffusive properties of microbial mats in two dimensions. Pulsed field gradient NMR was used to acquire im...
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...
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 ...
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...
