We report new measurements of inclusive pi production from frozen-spin HD for polarized photon beams covering the Delta(1232) resonance. These provide data simultaneously on both H and D with nearly complete angular distributions of the spin-difference cross sections entering...

In vivo release of neuroactive amines and amino acids from the hippocampus of seizure-resistant and seizure-susceptible rats.

Neurochemistry international

Lehmann A, Sandberg M, Huxtable RJ.
PMID: 20493082
Neurochem Int. 1986;8(4):513-20. doi: 10.1016/0197-0186(86)90185-3.

The in vivo release of six radiolabeled amino acids or amines in the hippocampus was investigated in genetically seizure-resistant and seizure-susceptible rats. No differences were found in the spontaneous or high K(+)-evoked efflux of ?-aminobutyric acid, norepinephrine or its...

Fast Estimation of the Vascular Cooling in RFA Based on Numerical Simulation.

The open biomedical engineering journal

Kröger T, Pätz T, Altrogge I, Schenk A, Lehmann KS, Frericks BB, Ritz JP, Peitgen HO, Preusser T.
PMID: 20448794
Open Biomed Eng J. 2010 Feb 04;4:16-26. doi: 10.2174/1874120701004020016.

We present a novel technique to predict the outcome of an RF ablation, including the vascular cooling effect. The main idea is to separate the problem into a patient independent part, which has to be performed only once for...

Long-term stability in continuous wave cavity ringdown spectroscopy experiments.

Applied optics

Appl Opt. 2010 Mar 10;49(8):1378-87. doi: 10.1364/AO.49.001378.

Allan variance has been used to characterize the slow drift of a near-IR distributed feedback laser-based continuous wave cavity ringdown spectroscopy (CW-CRDS) system. Long-term drift in the cavity loss rate, highly correlated with changes in ambient pressure but not...

Effective modulation of the donor properties of N-heterocyclic carbene ligands by "through-space" communication within a planar chiral scaffold.

Spatially and size selective synthesis of Fe-based nanoparticles on ordered mesoporous supports as highly active and stable catalysts for ammonia decomposition.

Journal of the American Chemical Society

Lu AH, Nitz JJ, Comotti M, Weidenthaler C, Schlichte K, Lehmann CW, Terasaki O, Schüth F.

J Am Chem Soc. 2010 Oct 13;132(40):14152-62. doi: 10.1021/ja105308e.

Uniform and highly dispersed γ-Fe(2)O(3) nanoparticles with a diameter of ∼6 nm supported on CMK-5 carbons and C/SBA-15 composites were prepared via simple impregnation and thermal treatment. The nanostructures of these materials were characterized by XRD, Mössbauer spectroscopy, XPS,...

Sensitivity limit of rapidly swept continuous wave cavity ring-down spectroscopy.

The journal of physical chemistry. A

Huang H, Lehmann KK.

J Phys Chem A. 2011 Sep 01;115(34):9411-21. doi: 10.1021/jp111177c. Epub 2011 Jul 26.

The averaged transmitted intensity of a cavity excited by a linearly frequency swept laser with finite line width is derived and presented as a sum over passes, analytical integrals (where the sum of passes is converted to a continuous...

(HCN)(m)-M(n) (M = K, Ca, Sr): vibrational excitation induced solvation and desolvation of dopants in and on helium nanodroplets.

The journal of physical chemistry. A

Douberly GE, Stiles PL, Miller RE, Schmied R, Lehmann KK.

J Phys Chem A. 2010 Mar 18;114(10):3391-402. doi: 10.1021/jp908834m.

Infrared (IR) laser spectroscopy is used to probe the rotational and vibrational dynamics of the (HCN)(m)-M(n) (M = K, Ca, Sr) complexes, either solvated within or bound to the surface of helium nanodroplets. The IR spectra of the (HCN)(m)-K...

Short-range correlations seen in the nematic phase of bent-core liquid crystals by dielectric and electro-optic studies.

Three bent-core nematic liquid crystals having the same core but with different terminal groups, short (C4) and long (C7,C9) tails, are investigated by dielectric and electro-optic contrast spectroscopic techniques. C4 shows sign reversal in the dielectric anisotropy Δε' as...
