It is shown that fluorine-containing anodic layers on the n-InAs(001) surface, in contrast to fluorine-free layers, form an interface with unpinned Fermi level, density of states which near midgap about 10 11 eV -1 · cm -2 (78 K ). The study chemical composition showed decrease associated formation indium and arsenic oxyfluorides interface. Keywords: InAs, MIS structure, fluorine, layer, states.

Fluorosis is a chronic disease caused by the body weight produces clinical signs after continued continued ingestion of small but toxic amounts of ingestion. fluorine in the diet or drinking water over a long duration In case of pregnant cows the fluorine content of leading the cumulative effect, while acute poisoning bones of new born calves depends on the dam’s intake occurs due to inhalation...

Organo-fluorine compounds are the substances of considerable interest in various industrial fields due to their unique physical and chemical properties. Despite increased demand in wide fields of science, synthesis of fluoro-organic compounds is still often faced with problems such as the difficulties in handling of fluorinating reagents and in controlling of chemical reactions. Recently, flow ...

We modelled the adsorption of benzene, fluorobenzene and meta-di-fluorobenzene on Cu(110) by Density Functional Theory. We found that the adsorption configuration depends on the coverage. At high coverage, benzene assumes a tilted position, while at low coverage a horizontal slightly distorted geometry is favoured. Functionalizing the benzene ring with one or two fluorine atoms weakens the bond...

The synthesis of 4-[18F]fluoroguaiacol (4-[18F]fluoro-2-methoxyphenol) has been achieved in no-carrier-added form starting from 2-methoxy-4-nitrobenzaldehyde, using nucleophilic aromatic substitution by [18F]fluoride followed by Baeyer-Villiger oxidation of the benzaldehyde to the phenol. Demethylation with boron tribromide gave 4-[18F]fluorocatechol (1,2-dihydroxy-4-[18F]fluorobenzene) with an...

As a functional decorative material on the surface of printing and packaging, coating plays role increasing gloss, wear resistance, antifouling. It has broad application prospects in high-end printed materials such as posters, art reproductions, maps. In this paper, dodecafluoroheptyl methacrylate was used fluorine-containing monomer, which to modify epoxy resin introduce fluoride first. Under ...

The main effect of the introduction of fluorine to diamond-like carbon (FDLC) thin films is the reduction in surface free energy (SFE). Regarding tribological properties, frequent allusions to low friction are found in the literature. However, studies proving a direct relationship between fluorine content in DLC films and macroscopic friction reduction are hard to find, while others state fluor...
