Enhancing the optoelectronic properties of amorphous zinc tin oxide by subgap defect passivation: A theoretical and experimental demonstration

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Monica Morales Masis, Jakub Holovsky, Martial Duchamp, Oscar Esteban Rucavado Leandro, Federica Landucci

The link between sub-bandgap states and optoelectronic properties is investigated for amorphous zinc tin oxide (a-ZTO) thin films deposited by RF sputtering. a-ZTO samples were annealed up to 500 °C in oxidizing, neutral, and reducing atmospheres before ch ...

Self-assembly and redox induced phase transfer of gold nanoparticles at the water-propylene carbonate interface

Hubert Girault, Pekka Eero Peljo, Evgeny Smirnov

Citrate-stabilized gold nanoparticles were found to spontaneously self-assemble into a lustrous film at a bare water–propylene carbonate interface after vigorous shaking, due to the extremely low interfacial tension. The presence of an electron donor, tetr ...

Assemblies of gold nanoparticles at liquid-liquid interfaces

Evgeny Smirnov

The interface between two immiscible liquids, i.e. oil and water, is an extremely attractive scaffold to self-assemble nanoparticles (NP) in arranged films. The liquid-liquid interfaces (LLIs) are defect-free and pristine by the nature, they are transparen ...

Dehalobacter – a genus of anaerobic bacteria dedicated to organohalide degradation

Christof Holliger, Julien Maillard

Abstract The genus Dehalobacter embraces bacterial populations that seem to exclusively degrade organohalides. All isolates in pure culture and highly enriched strains are obligate organohalide-respiring bacteria that use hydrogen as energy and electron so ...

Electrochemical Studies of Water Splitting in Organic Media

Jonnathan Cesar Hidalgo Acosta

The development of new routes towards the generation of environmentally friendly solar fuels, such as molecular hydrogen (H2) for use in fuel cells, is a grand challenge facing the scientific community. In this regard, water splitting represents one of the ...

A molecular chaperone dedicated to folding and translocation of reductive dehalogenases

Julien Maillard, Corantin Grob

Reductive dehalogenases (rdhA, RDases) are key enzymes involved in anaerobic organohalide respiration (OHR), during which bacteria are able to use chlorinated compounds as terminal electron acceptors. RDases are redox enzymes containing FeS clusters and a ...

Synthesis and optoelectronic properties of chemically modified bi-fluorenylidenes

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Robin Humphry-Baker, Magdalena Anna Marszalek, Mateusz Barnaba Wielopolski

The development of new light harvesting materials is a key issue for the progress of the research on organic & hybrid photovoltaics. Here, we report a new class of organic sensitizers based on the bi-fluorenylidene moiety as p-linker within the donor–p-lin ...

Rates of microbial hydrogen oxidation and sulfate reduction in Opalinus Clay rock

Rizlan Bernier-Latmani, Alexandre Bagnoud

Hydrogen gas (H2) may be produced by the anoxic corrosion of steel components in underground structures, such as geological repositories for radioactive waste. In such environments, hydrogen was shown to serve as an electron donor for autotrophic bacteria. ...

Photo-induced oxidation of the uniquely liganded heme f in the cytochrome b(6)f complex of oxygenic photosynthesis

Frank van Mourik, Andre Al Haddad, Adrien Alexis Paul Chauvet, Rachna Agarwal

The ultrafast behavior of the ferrous heme f from the cytochrome b(6)f complex of oxygenic photosynthesis is revealed by means of transient absorption spectroscopy. Benefiting from the use of microfluidic technologies for handling the sample as well as fro ...
