Ag loaded TiO2 was applied in the photocatalytic inactivation of Escherichia coil under ultraviolet (UV) and visible (Vis) light irradiations. Ag enhanced the TiO2 photodisinfecting effect under Vis irradiation promoting the formation of singlet oxygen and ...
MEMS-based programmable slit masks are developed for multi-object spectroscopy in astronomy. Devices with 2048 tiltable micromirrors were fabricated and tested, exhibiting very good surface flatness, high contrast and cryogenic operation ability. ...
Reconstructions of past atmospheric concentrations of greenhouse gases provide unique insight into the biogeochemical cycles and the past radiative forcing in the Earth's climate system. We present new measurements of atmospheric nitrous oxide along the ic ...
We apply methods from extreme value theory to identify extreme events in high (termed EHOs) and low (termed ELOs) total ozone and to describe the distribution tails (i.e. very high and very low values) of five long-term European ground-based total ozone ti ...
Les études menées par l'Office Fédéral de l'Environnement (OFEV) ont montré l'efficacité de l'ozone pour l'abattement des micropolluants, substances organiques qui sont difficilement dégradables et issues de diverses provenances. Suite à la mise en place d ...
Introduction: beta-Amyloid (A beta) plaques and neurofibrillary tangles are the main characteristics of Alzheimer's disease (AD). Positron emission tomography (PET), a high-resolution, sensitive, and noninvasive imaging technique, has been widely utilized ...
The fourth report of the Intergovernmental Panel of Climate Change (IPCC) unambiguously indicates that the climate is changing. Climate change is induced by changes in atmospheric abundances of greenhouse gases and aerosols, solar radiation and land surfac ...
The kinetics of oxidation and disinfection processes during ozonation in a full-scale reactor treating secondary wastewater effluent were investigated for seven ozone doses ranging from 0.21 to 1.24 g O-3 g(-1) dissolved organic carbon (DOG). Substances re ...
Poly(vinylpyrrolidone) (PVP)-stabilized Pd nanocubes were synthesized, deposited on a carbon-based support, and subsequently treated with UV-ozone (UVO) in order to eliminate the traces of PVP still present on the surface. Cubes, being a thermodynamically ...
Carbon nanofibres (CNFs) were grown on different macrostructured supports such as cordierite monoliths, carbon felts and sintered metal fibres. The resulting composites exhibited excellent resistance to attrition/corrosion and its porosity is mainly due to ...
