We present recent results on elastic and inelastic low/medium energy electron interaction with tetrahydrofuran, C4H8O, tetrahydrofurfuryl alcohol, C5H10O2 and 3hydroxytetrahydrofuran, C4H8O2 molecules in gaseous phase. A comparative study of both absolute differential cross sections for elastic electron scattering and electron energy loss spectra, in a wide incident electron energy range from 5...

A reaction scheme is proposed to account for the liberation of 4-benzylaniline from 4-benzylaniline hydrochloride, using chlorobenzene as a solvent at a temperature of 373 K. Two operational regimes are explored: “closed” reaction conditions correspond to the retention of evolved hydrogen chloride gas within the reaction medium, whereas an “open” system permits gaseous hydrogen chloride to be r...

Atmospheric oxidation of monoterpenes contributes to formation of tropospheric ozone and secondary organic aerosol, but their products are poorly characterized. In this work, we report a series of outdoor smog chamber experiments to investigate both gaseous and particulate products in the ozone oxidation of four monoterpenes: α-pinene, β-pinene, 13-carene, and sabinene. More than ten oxygenated...

Several plant species reveal the tolerance to acute desiccation stress (eg. Antarctic lichens [3,4,5]). During rehydration process they can take water directly from gaseous phase in [2]. These facts focus the attention on the response of the isolated cell organellae to extreme environmental conditions. Photosynthetic membranes were selected by their importance for plant photosynthetic activity....

The high external surface area leads to a significant increase in the surface contact between the gaseous or liquid reactants and the active phase supported on this nanostructured host which is a prerequisite for its use as catalyst support, especially in liquid phase medium where diffusion rate is predominant [2]. Also, the strong interactions between the exposed prismatic planes and the depos...

Mass spectrometric studies of the vapours over solid lead oxide in a flow of gaseous arsenic and antimony trioxides were conducted. The following ions of the ternary oxides were detected: Pb3As2O6(+), Pb3AsO4(+), PbAs2O4(+), PbAsO2(+), PbSb2O4(+), and PbSbO2(+). The origin of these species produced by the ionisation and/or fragmentation of ternary gaseous oxides is discussed. The PbAs2O4 specie...

The copolymerizations of a gaseous monomer (ethylene) and a liquid monomer (vinyl acetate) via emulsion and miniemulsion polymerizations are reported. Reactions in which the vinyl acetate was introduced in both batch and semibatch modes are carried out. (Ethylene introduction is always in a semibatch model since the polymerization is carried out under a constant pressure of ethylene in the reac...

Reactions of gaseous SF(3)(+) ions with furan, thiophene, pyrrole, and several of their alkyl derivatives were performed via MS(2) experiments and found to occur readily both by electron abstraction and F(+) transfer. Then, by performing MS(3) experiments, the F(+) transfer products-the protonated monofluorinated molecules-were mass-selected and deprotonated by a second reaction with a stronger...
