Using FTIR and Raman spectroscopy, the formation of halogen bonded complexes of the trifluorohalomethanes CF(3)Cl, CF(3)Br and CF(3)I with dimethyl sulfide (DMS) dissolved in liquid krypton has been investigated. For CF(3)Br and CF(3)I, evidence was found for the formation of C-XS halogen bonded 1:1 complexes. At higher concentrations of CF(3)I weak absorptions due to a 2:1 complex were also ob...

Abstract. Aerosol indirect radiative forcing (IRF), which characterizes how aerosols alter cloud formation and properties, is very sensitive to the preindustrial (PI) aerosol burden. Dimethyl sulfide (DMS), emitted from ocean, a dominant natural precursor of non-sea-salt sulfate in PI pristine present-day (PD) atmospheres. Here we revisit atmospheric oxidation chemistry DMS, particularly under ...

• DMS efficiently degraded by UiO-66@TiO 2 synthesized through a solvothermal method. UiO-66 served as adsorbent, support and photocatalyst in composite. Highest photodegradation efficiency of observed at 60% relative humidity. U1T3 showed advantageous cycling performance. Photocatalytic mechanism degradation kinetics were illustrated. The photocatalytic activity titanium dioxide (TiO ) for the...

in this work, zncao2 (zinc oxide-calcium oxide) nanocomposite were synthesized at different temperatures (500-700°c) by sol-gel method based on polymeric network of polyvinyl alcohol (pva). the synthesized samples were characterized by sem/edax, ft-ir and xrd techniques. it was found that synthesized nanocomposites have 1.62, 2.05 and 13.91%wt of cao, respectively. the obtained results show tha...
