The effect of a magnetic field in the perpendicular-to-electrode configuration on the hydrogen evolution reaction (HER) was investigated during the deposition of Co. An enhanced desorption of hydrogen in the form of numerous small bubbles was found by combining potentiostatic investigations, coupled with an electrochemical quartz crystal microbalance (EQCM), and simultaneous microscopic observations of the electrode surface. The results are consistent with the recently proposed qualitative model [J.A. Koza, M. Uhlemann, A. Gebert, L. Schultz, Electrochem. Commun. 10 (2008) 1330]. 相似文献

We present a study of the LHC sensitivity to the W boson mass based on simulation studies. We find that both experimental and phenomenological sources of systematic uncertainties
can be strongly constrained with Z measurements: the lineshape, dσ

while the differential cross-section analysis, d2

∼7 MeV for each decay channel (W→e
ν, W→μ
ν), and for an integrated luminosity of 10 fb−1, appears as a reasonable goal. 相似文献

A full account on the synthesis of the antibiotic natural product biphenomycin B and several derivatives is reported, which employs a Suzuki coupling reaction of a free carboxylic acid and macrolactam formation as key transformations. Liberal exchange of the central amino acid was demonstrated. This procedure gave derivatives to study the influence of the polar side chain of the central amino acids on translation inhibition. 相似文献
