Perspectives of shaped pulses for EPR spectroscopy.

Journal of magnetic resonance (San Diego, Calif. : 1997)

Spindler PE, Schöps P, Kallies W, Glaser SJ, Prisner TF.
PMID: 28579101
J Magn Reson. 2017 Jul;280:30-45. doi: 10.1016/j.jmr.2017.02.023.

This article describes current uses of shaped pulses, generated by an arbitrary waveform generator, in the field of EPR spectroscopy. We show applications of sech/tanh and WURST pulses to dipolar spectroscopy, including new pulse schemes and procedures, and discuss...

Whole transcriptome analysis for T cell receptor-affinity and IRF4-regulated clonal expansion of T cells.

Genomics data

Shi W, Man K, Smyth GK, Nutt SL, Kallies A.
PMID: 26484137
Genom Data. 2014 Nov 01;2:396-8. doi: 10.1016/j.gdata.2014.10.019. eCollection 2014 Dec.

Clonal population expansion of T cells during an immune response is dependent on the affinity of the T cell receptor (TCR) for its antigen [1]. However, there is little understanding of how this process is controlled transcriptionally. We found...

Prediction of Ternary Liquid Adsorption on Solids from Binary Data.

The adsorption behavior of the ternary n-hexane/n-octane/n-tetradecane mixture and the binary n-hexane/n-octane, n-octane/n-tetradecane, n-hexane/n-tetradecane mixtures on the well-characterized TA 95 activated carbon has been studied. Measured binary data at 25 degrees C are used to predict the ternary data...

55Mn NMR investigation of electronic phase separation in La1-xCaxMnO3 for 0.2 < or = x < or = 0.5.

Physical review letters

Papavassiliou G, Fardis M, Belesi M, Maris TG, Kallias G, Pissas M, Niarchos D, Dimitropoulos C, Dolinsek J.
PMID: 11017366
Phys Rev Lett. 2000 Jan 24;84(4):761-4. doi: 10.1103/PhysRevLett.84.761.

55Mn NMR line shape measurements in La1-xCaxMnO3 for 0.20< or =x< or =0.50 provide experimental evidence about the existence of two distinct regions in the T-x magnetic phase diagram, where the homogeneous ferromagnetic (FM) metallic state is separated into...

Electronic structure of 3d[M(H2O)6](3+) ions from Sc(III) to Fe(III): a quantum mechanical study based on DFT computations and natural bond orbital analyses.

Inorganic chemistry

Kallies B, Meier R.
PMID: 11399179
Inorg Chem. 2001 Jun 18;40(13):3101-12. doi: 10.1021/ic001258t.

The metal-donor atom bonding along the series of 3d[M(H2O)6](3+) ions from Sc(3+) to Fe(3+) has been investigated by density-functional calculations combined with natural localized bond orbital analyses. The M-OH(2) bonds were considered as donor-acceptor bonds, and the contributions coming...

Prediction of multicomponent liquid adsorption using excess quantities. II. Calculations for the liquid/solid interface.

Journal of colloid and interface science

Kalies G, Bräuer P, Messow U.
PMID: 15178267
J Colloid Interface Sci. 2004 Jul 15;275(2):410-8. doi: 10.1016/j.jcis.2004.02.091.

The utilization of excess quantities as the basis for a thermodynamic approach can simplify the prediction of multicomponent liquid adsorption from binary data. A new method for predicting liquid adsorption on solids is suggested, which is different from the...

Liquid adsorption of n-octane/octanol/ethanol on SBA-16 silica.

Journal of colloid and interface science

Rockmann R, Kalies G.
PMID: 17631307
J Colloid Interface Sci. 2007 Nov 01;315(1):1-7. doi: 10.1016/j.jcis.2007.06.029. Epub 2007 Jun 21.

SBA-16 silica samples with cubic Im3 m symmetry were synthesized according to methods reported in literature and characterized by nitrogen adsorption and X-ray diffraction. The adsorption behavior of the n-octane(1)/octanol(2), n-octane(1)/ethanol(3), and octanol(2)/ethanol(3) binary liquid mixtures on SBA-16 was...

In situ nuclear magnetic resonance of N pulse labels monitors different routes for nitrogen assimilation.

Plant physiology

Recent debates on the oxygen redox behaviors in battery electrodes have triggered a pressing demand for the reliable detection and understanding of nondivalent oxygen states beyond conventional absorption spectroscopy. Here, enabled by high-efficiency mapping of resonant inelastic X-ray scattering...
