Stereospecific Assignment of the Asparagine and Glutamine Side Chain Amide Protons in Random-Coil Peptides by Combination of Molecular Dynamic Simulations with Relaxation Matrix Calculations

27.11.2012 | T. Harsch, C. Dasch, H. Donaubauer, K. Baskaran, W. Kremer, H. R. Kalbitzer, Applied Magnetic Resonance, 2012

A database with correct stereospecific assignment is also important for accurate chemical shift prediction. Here, usually chemical shifts of random-coil model peptides or from a protein database are used for correct parameterization. However, an analysis of the data stored in the Biological ...


Probing Structural Compositions of Porous Media with Two-dimensional Nuclear Magnetic Resonance

26.11.2012 | Huabing Liu, Lizhi Xiao, Huijun Yu, Xin Li, Baoxin Guo, Zongfu Zhang, Fangrong Zong, Vladimir Anferov, Sofia Anferova, Applied Magnetic Resonance, 2012

Combination of two-dimensional nuclear magnetic resonance (2-D NMR) correlation maps and a simple three-component model are proposed here to identify the structural composition of porous media. Homogeneous magnetic field and field with constant gradient of a novel Halbach sensor are employed for ...


EPR Study of the Vanadium Ions in Mg2SiO4 Crystal

19.11.2012 | I. N. Gracheva, A. A. Rodionov, N. I. Silkin, R. V. Yusupov, V. B. Dudnikova, E. V. Zharikov, V. F. Tarasov, Applied Magnetic Resonance, 2012

Vanadium-doped forsterite crystal has been studied with X-band electron paramagnetic resonance (EPR) spectroscopy. The sample was grown by the Czochralski technique in an argon atmosphere with 2 vol% of hydrogen. The EPR spectrum of the sample at T = 15 K is predominantly represented by the V4+ ...


EPR Study of γ-Irradiated UHMWPE Doped with Vitamin E: Assessment of Thermal Effects on the Organic Radicals During Vitamin E Diffusion

19.11.2012 | Malik Sajjad Mehmood, Tariq Yasin, Muhammad Shah Jahan, Benjamin Michael Walters, Manzoor Ahmad, Masroor Ikram, Applied Magnetic Resonance, 2012

Thermal effects on ultra-high-molecular-weight polyethylene (UHMWPE) residual radicals during the vitamin E diffusion process were studied in detail. Electron paramagnetic resonance (EPR) technique showed a significant reduction in concentrations of radiation-induced primary (alkyl (–CH2– ...


Light-Induced Spin Polarization in Porphyrin-Based Donor–Acceptor Dyads and Triads

19.11.2012 | Art van der Est, Prashanth K. Poddutoori, Applied Magnetic Resonance, 2012

The light-induced spin polarization generated by sequential electron transfer in an axially bound triad based on Al(III) porphyrin (AlPor) is discussed. In the triad, ext TTF - ext Ph - ext py® ext AlPor - ext Ph - ext NDI, the electron acceptor naphthalene diimide (NDI) is attached covalently to ...


Generating Parahydrogen-Induced Polarization Using Immobilized Iridium Complexes in the Gas-Phase Hydrogenation of Carbon–Carbon Double and Triple Bonds

19.11.2012 | Ivan V. Skovpin, Vladimir V. Zhivonitko, Robert Kaptein, Igor V. Koptyug, Applied Magnetic Resonance, 2012

Immobilized iridium complexes synthesized using [Ir(COD)Cl]2 by anchoring on hydrous and anhydrous silica gels were studied in terms of generating parahydrogen-induced polarization (PHIP) in the gas-phase hydrogenation of propylene and propyne. Distinguishing differences in the hydrogenations of ...

Configuration and Performance of a Mobile 129Xe Polarizer

10.11.2012 | Sergey E. Korchak, Wolfgang Kilian, Lorenz Mitschang, Applied Magnetic Resonance, 2012

A stand-alone, self-contained and transportable system for the polarization of 129Xe by spin exchange optical pumping with Rb is described. This mobile polarizer may be operated in batch or continuous flow modes with medium amounts of hyperpolarized 129Xe for spectroscopic or small animal ...


Measuring Cu2+-Nitroxide Distances Using Double Electron–Electron Resonance and Saturation Recovery

09.11.2012 | Jessica Sarver, K. Ishara Silva, Sunil Saxena, Applied Magnetic Resonance, 2012

Distance measurements were obtained between a bound Cu2+ and a spin label on two polypeptides of differing length using the double electron–electron resonance (DEER) and saturation recovery experiments. Distance distributions obtained from the DEER results resolved differences between the average ...


Erratum to: A Calibration Reaction for Rapid Freeze-Quench W-Band EPR

05.11.2012 | Alexey Potapov, Daniella Goldfarb, Applied Magnetic Resonance, 2012

Erratum to: A Calibration Reaction for Rapid Freeze-Quench W-Band EPR Content Type Journal Article Category Erratum Pages 1-1 DOI 10.1007/s00723-012-0424-8 Authors Alexey Potapov, Department of Chemical Physics, Weizmann Institute of Science, Rehovot, Israel Daniella Goldfarb, ...
