Abstract Betahistine serves as a medicament widely used in curing some diseases related to the nervous system. Its molecular properties have been studied by ab initio MO-LCAO-SCF method followed correction electron correlation (MP2) vacuo well water solvent. The chemical potential (electronegativity) and hardness were verified valuable descriptors compared with structurally analogous species.

The correlation of the electrocatalytic activity with electrical conductivity, oxygen-vacancies, and electronegativity have been studied in a series isostructural oxides, having so-called Ruddlesden-Popper structure. structures these materials comprise transition metals that are octahedrally coordinated to form network bilayer stacks. These catalytically active for both half-reactions water-spl...

The capacitively coupled Ar plasma containing oxygen, driven by a radio frequency of 27.12 MHz, is investigated laser-induced photo-detachment technique assisted with Langmuir probe. plasmas different amounts oxygen are obtained changing the flow and each which controlled mass controller. axial distribution characteristic can be measured relative position probe between parallel electrodes. elec...

The discovery of the extremely shallow amorphous boron-crystalline silicon heterojunction occurred during development highly sensitive, hard and robust detectors for low-penetration-depth ionizing radiation, such as ultraviolet photons low-energy electrons (below 1 keV). For many years it was believed that junction created by chemical vapor deposition boron on n-type crystalline a p-n junction,...

Fluoride has long been known to influence the activity of various enzymes in vitro. Latterly it has been demonstrated that many effects primarily attributed to fluoride are caused by a synergistic action of fluoride plus aluminum. Fluorinated chemicals are of growing importance, with applications in medicine. Fluorine substitution has profound effects on the properties of organic compounds. The...
