Using Grazing-incidence small-angle scattering (GISAXS) technique we investigated the surface morphology of polymer films spin-coated on different silicon substrates. As substrates we used either technologically smooth silicon wafers or the same silicon wa ...
Several recent reports have indicated that some bacteria may have adapted to the low bioavailability of hydrophobic environmental chemicals and that generalizations about the bioavailability of compounds such as polycyclic aromatic hydrocarbons (PAHs) may ...
A novel C-Nafton/Fe-ion structured fabric capable of mediating Orange II decomposition in Fenton-immobilized photoassisted reactions is presented. The catalyst preparation requires the right balance between the amount of the Nafion necessary to protect the ...
Poly(tetrafluoroethylene) (PTFE) films were surface-modified by employing a reaction solution of benzophenone and sodium hydride in anhydrous dimethylformamide at a temperature of 150 degrees C for 12 h. Electron spectroscopy for chemical analysis (ESCA) s ...
2,4-Difluorophenol, 2,5-difluorophenol, 2,3-difluorophenol, 3,5-difluorophenol, 3,4-difluorophenol, 2,4,5-trifluorophenol and 2,3,4-trifluorophenol were converted into all 18 possible di- or trifluorinated hydroxybenzoic acids, all of them new compds. The ...
The repetitive discoloration kinetics of the azo-dye Methyl Orange (taken as a model organic compound) was followed under solar simulated radiation (90 mW/cm2) to assess the performance of the TiO2/Tedlar® composite photocatalyst. The influence of solution ...
The present work analyses silicon oxide coated polyester films, with attention paid to the effect of substrate process additives on the coating defect population, and on the coated film mechanical properties. The defect population is characterized by means ...
The surface properties and the electrochem. behavior of a fluorinated B-doped diamond (F-BDD) electrode prepd. by plasma treatment in CF4-He mixt. was studied by XPS and cyclic voltammetry in acidic media. The results showed C-F bonding (C-CF and C-F) on t ...
The low-pressure phase diagram of solid poly(tetrafluoroethylene) (PTFE/Teflon) has been investigated using const.-temp./const.-pressure mol.-dynamics techniques and a new all-atom potential model for fluorocarbons. The simulation was started in an ordered ...
The anodic oxidn. of H2SO4 to H2S2O8 was investigated on B-doped synthetic diamond electrodes obtained by hot filament chem. vapor deposition. High current efficiency for H2S2O8 formation can be achieved in concd. H2SO4 (7.5 mol dm-3) and using high curren ...
