Accelerated Escherichia coli inactivation in the dark on uniform copper flexible surfaces

César Pulgarin, Michaël Bensimon, Juan Kiwi, 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 Society2014

Easily-prepared dinickel phosphide (Ni2P) nanoparticles as an efficient and robust electrocatalyst for hydrogen evolution

Xile Hu, Michaël Bensimon, Heron Vrubel, Ligang Feng

Polydispersed dinickel phosphide (Ni2P) nanoparticles were synthesized by a simple and scalable solid-state reaction. These nanoparticles are an excellent and robust catalyst for the electrochemical hydrogen evolution reaction, operating in both acidic and ...

Direct determination of niobium at the low nanogram level in mineral waters and freshwaters

Michaël Bensimon, Montserrat Filella, David-Julien Magnenat

The increasing use of elements such as Nb and Ta in green and information technologies makes it necessary to develop appropriate analytical methods for studying their environmental and ecotoxicological behaviour. This paper describes the first time Nb has ...

Effect of surface pretreatment of TiO2 films on interfacial processes leading to bacterial inactivation in the dark and under light irradiation

César Pulgarin, Michaël Bensimon, Juan Kiwi, Sami Rtimi, Rosendo Sanjines, Jelena Nesic

Evidence is presented for radio-frequency plasma pretreatment enhancing the amount and adhesion of TiO2 sputtered on polyester (PES) and on polyethylene (PE) films. Pretreatment is necessary to attain a suitable TiO2 loading leading to an acceptable Escher ...

TiON 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 ...

Evidence 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 ...

ZrNO-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 ...

Over-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- ...

Road 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 ...

Rare 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 ...
