Effect of light and oxygen on repetitive bacterial inactivation on uniform, adhesive, robust and stable Cu-polyester surfaces

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

This study reports new findings on the sputtered Cu-polyester (Cu-PES) bacterial inactivation under low intensity visible light (lambda > 400 nm). Cu-PES samples sputtered for 160 s led to the complete inactivation of E. coli in anaerobic and aerobic media ...

Morphology and composition of oxidized InAs nanowires studied by combined Raman spectroscopy and transmission electron microscopy

Anna Fontcuberta i Morral, Esther Alarcon Llado, Francesca Amaduzzi

importance for semiconductor nanowires because of the high surface-to-volume ratio and only little is known about the consequences of oxidation for these systems. Here, we study the properties of indium arsenide nanowires which were locally oxidized using ...

Chlorambucil conjugates of dinuclear p-cymene ruthenium trithiolato complexes: synthesis, characterization and cytotoxicity study in vitro and in vivo

Paul Joseph Dyson, Patrycja Nowak-Sliwinska

Four diruthenium trithiolato chlorambucil conjugates have been prepared via Steglich esterification from chlorambucil and the corresponding trithiolato precursors. All conjugates are highly cytotoxic towards human ovarian A2780 and A2780cisR cancer cell li ...

Insight on the photocatalytic bacterial inactivation by co-sputtered TiO2-Cu in aerobic and anaerobic conditions

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Stefanos Giannakis

Co-sputtered TiO2-Cu polyester (TiO2-Cu-PES) under actinic light induced bacterial reduction of E. coli in the presence of O2 (air) and under anaerobic conditions. The bacterial inactivation/oxidation proceeds in the absence of O2 (air) probably due to the ...

Layered polymer-zeolitic imidazolate framework composites fabricated using sacrificial, metal-oxide, nanocrystal precursors

Raffaella Buonsanti, Wendy Lee Queen

While polymers are frequently used as membranes in industrial-scale sepns. due to their ease of synthesis and processing, their performance is limited by a well-documented permeability/selectivity tradeoff. A class of metal-org. frameworks known as zeoliti ...

Compact portable biosensor for arsenic detection in aqueous samples with Escherichia coli bioreporter cells

Philippe Renaud, Harald Van Lintel, Nina Buffi

We present a compact portable biosensor to measure arsenic As(III) concentrations in water using Escherichia coli bioreporter cells. Escherichia coli expresses green fluorescent protein in a linearly dependent manner as a function of the arsenic concentrat ...

Doping Nature of Native Defects in 1T-TiSe2

Helmuth Berger, Philipp Aebi

The transition-metal dichalcogenide 1T-TiSe2 is a quasi-two-dimensional layered material with a charge density wave (CDW) transition temperature of T-CDW approximate to 200 K. Self-doping effects for crystals grown at different temperatures introduce struc ...

Revealing and Accelerating Slow Electron Transport in Amorphous Molybdenum Sulphide Particles for Hydrogen Evolution Reaction

Michael Graetzel, Xile Hu, Thomas Moehl, Heron Vrubel

Electrochemical impedance spectroscopy is used to identify a slow electron transport process in hydrogen evolution catalysed by amorphous molybdenum sulphides on glassy carbon. A new chemical synthesis leads to an amorphous molybdenum sulfide catalyst with ...
