New experimental study of heavy ion and proton induced SEU at reduced voltage (i.e. reduced critical charge) reveals interesting results. It is shown that the heavy ion cross section and microprobe mapping scale like the threshold LET and the parameter, wh ...
We exploited resonant photoemission at the Ce 4d --> 4f absorption edge to investigate the Ce 4f states in CePd3. High resolution spectra reveal, near the Fermi level, the characteristic fine structure of intermediate valence Ce compounds. The spectral lin ...
The effects of background n- and p-type doping on Zn diffusion in GaAs/AlGaAs multilayered structures are investigated by secondary-ion-mass spectrometry and photoluminescence measurements. Zn diffusions are performed at 575 degrees C into Si-doped, Be-dop ...
A review, with 9 refs., is given on trace element anal. by mass spectrometry (MS) and potentiometric stripping anal. (PSA). The key question of the problem is detn. of the structure of the samples (i.e. distribution functions and concns. of atoms, mols., c ...
The adsorption of isobutane on a Pt(533) stepped surface has been investigated using temperature programmed desorption (TPD) and reflection absorption infrared spectroscopy (RAIRS). Isobutane exists in two monolayer states and one multilayer phase on the P ...
Human retinol-binding protein (RBP) is a monomeric 21-kDa protein that is currently the subject of numerous studies owing to its role in the cellular uptake and utilization of retinol. When the RBP gene is overexpressed in Escherichia coli, inclusion bodie ...
he mol. structures were calcd. for tetraaminoethylene (1)and its isomer 2,2-diaminoacetamidine (2)in the frameworks of DFT and MP2 methods. Ionization potential, potential energy surface, dissocn. energy onto aminocarbenes, and transition state structure i ...
The present work deals with two subjects. The interaction of NO2 and HONO with different types of soot are examined in the first part whereas in the second part an experimental set-up is presented which has been built in order to measure the kinetics of th ...
Higher Rydberg states of NO trapped in rare gas matrixes were studied by inducing Rydberg-Rydberg transitions from the lowest A2S+ (3ss) Rydberg state and detecting its fluorescence depletion. This technique unravels Rydberg states, which cannot be accesse ...
Solutions of the strong complexing agent ethylenediaminetetraacetic acid (EDTA) and Cu, Pb, Cd, Al, and Fe(III) were examined by electrospray mass spectrometry (ES/MS). Uncomplexed EDTA and metal-EDTA complexes survive the electrospray process intact and c ...
