Abstract The diffusion of potassium in SrTiO3 (STO) single crystals is investigated as a function of temperature. Charge attachment induced transport experiments are employed inducing diffusion profiles in STO evolving with time. Potassium concentrat

Ion–molecule reactions in the HBr+ + HCl (DCl) system: a combined experimental and theoretical study
Publikováno v:
Physical Chemistry Chemical Physics. 25:2629-2640
Reactions in the system HBr+ + HCl (DCl) were investigated by combined experimental and theoretical efforts: (i) inside a guided ion-beam apparatus under single-collision conditions and (ii) by ab initio molecular dynamic simulation.

Many sophisticated approaches for analyzing properties of chiral matter have been developed in recent years. But in general, the available chiroptical methods are limited to either solvated or small gaseous molecules. Studying the chirality of large

Here, we report the coincident measurement of PICD and PECD effects in 1-phenylethylamine upon multiphoton ionization. Both photo-ion circular dichroism (PICD) and photo-electron circular dichroism (PECD) are methods to distinguish enantiomers. In PI

The ionic conductivity of alkali aluminum germanium phosphates (MAGP) has been investigated by two different techniques, i.) a fs-Plasma-Charge Attachment Induced Transport (CAIT) approach and ii.) a classical two electrode DC approach. Amorphous MAG

The dynamics of the HBr+ + CO2 → HOCO+ + Br reaction was recently investigated with guided ion beam experiments under various excitations (collision energy of the reactants, rotational and spin-orbital states of HBr+, etc.), and their impacts were

Electro-thermal poling of a technical glass containing mobile Na+ and K+ ions is investigated in an experiment. Ex-situ analysis of the concentration profiles by means of ToF-SIMS demonstrates the formation of two zones; a zone depleted of both Na+ a
