Accelerated Escherichia coli inactivation in the dark on uniform copper flexible surfaces
César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines
The bacterial inactivation of Escherichia coli on Cu/CuO-polyester surfaces prepared by direct current magnetron sputtering was investigated in the dark and under actinic light (360nm
American Vacuum Society2014Determination of Pt in digested animal plasma and tissues using High Resolution Inductively Coupled Plasma HR-ICP-MS.
Determination of Pt in digested animal plasma and tissues using High Resolution Inductively Coupled Plasma HR-ICP-MS. Samples were measured in Low Resolution LR mode considering Pt(194), Pt(195), Pt(196), and Pt(198). In order to minimize the matrix effect ...
2014Mesoscopic photosystems for solar light harvesting and conversion: facile and reversible transformation of metal-halide perovskites
Michael Graetzel, Michaël Bensimon, Nicolas Tétreault, Norman Pellet, Hauke Arne Harms
Recently, hybrid organic-inorganic metal halide perovskites have gained prominence as potent light harvesters in thin film solid-state photovoltaics. In particular the solar-to-electric power conversion efficiency (PCE) of devices using CH3NH3PbI3 as sensi ...
Royal Society of Chemistry2014TiON and TiON-Ag sputtered surfaces leading to bacterial inactivation under indoor actinic light
César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Oualid Baghriche
This study reports the details Escherichia coli inactivation kinetics on TiON and TiON-Ag films sputtered on polyester by direct current reactive magnetron sputtering (DC) and pulsed magnetron sputtering (DCP) in an Ar/N2 /O2 atmosphere. The use of TiON le ...
2013ZrNO-Ag co-sputtered surfaces leading to E. coli inactivation under actinic light: Evidence for the oligodynamic effect
César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Mirela Pascu
This study reports visible light sensitive ZrNO and ZrNO-Ag polyester samples prepared by sputtering in an Ar/N-2/O-2 atmosphere leading to Escherichia coil bacterial inactivation. The bacterial inactivation by ZrNO avoids the increasing environmental conc ...
Elsevier2013Evidence for TiON sputtered surfaces showing accelerated antibacterial activity under simulated solar irradiation
César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi
New evidence is reported for TiON sputtered polyester surfaces activated by sunlight irradiation leading to the accelerated bacterial inactivation in the minute range. The absorption in Kubelka-Munk units of the TiON film was observed to be directly propor ...
Elsevier2013Over-expression of PHO1 in Arabidopsis leaves reveals its role in mediating phosphate efflux
Michaël Bensimon, Charles Vidoudez
P>Inorganic phosphate (Pi) homeostasis in multi-cellular eukaryotes depends not only on Pi influx into cells, but also on Pi efflux. Examples in plants for which Pi efflux is crucial are transfer of Pi into the xylem of roots and release of Pi at the peri- ...
Wiley-Blackwell2011Road runoff management using over-the-shoulder infiltration: real-scale experimentation
Aurèle Parriaux, Michaël Bensimon, Pascal Piguet
A new management policy regarding road runoff was proposed in 2002 by the Swiss Federal Office for the Environment (FOEN). This new concept is based on the diffuse infiltration of road runoff into embankment slopes, where soils will filter particles and co ...
IWA Publishing2009Rare earth elements in groundwater from different Alpine aquifers
Aurèle Parriaux, Michaël Bensimon
Rare earth elements (REE) were determined in 39 groundwater samples collected at 14 sites under low- and high-flow conditions. Water samples derived from aquifers hosted in crystalline, molasse, flysch, carbonate and evaporite rocks located in Western Swit ...
2009The diffuse infiltration of road runoff: an environmental improvement
Aurèle Parriaux, Michaël Bensimon, Pascal Piguet
The Laboratory of Engineering and Environmental Geology (GEOLEP) has been mandated by Swiss authorities (Swiss Federal Road Office FedRO) to test a new road runoff management concept. This concept promotes the diffuse infiltration of road runoff into infil ...
