Zinc carboxylate optimization strategy for extending Al-air battery system's lifetime

Andreas Züttel, Liping Zhong, Thi Ha My Pham, Manhui Wei

Although Al-air batteries are expected to be the candidates for energy conversion systems in renewable energy market due to the higher energy density, richer reserves, and lighter mass of Al metal, the anode self-discharge is seen as a notorious issue that ...

Tuning Napththalenediimide Cations for Incorporation into Ruddlesden–Popper-Type Hybrid Perovskites

Jacques-Edouard Moser, Kevin Sivula, Jun Ho Yum, Liang Yao, Etienne Christophe Socie, Simon Nussbaum

Layered hybrid organic−inorganic perovskite (LHOIP) materials constructed with low-band-gap chromophore-based organic spacer cations are anemerging class of materials that promise unique tunability of their optoelectronic properties. However, the large siz ...

Structural description of surfaces and interfaces in biominerals by DNP SENS

David Lyndon Emsley

Biological mineralized tissues are hybrid materials with complex hierarchical architecture composed of biominerals often embedded in an organic matrix. The atomic-scale comprehension of surfaces and organo-mineral interfaces of these biominerals is of para ...

An alternative model for the formation of hydrous Mg/Ni layer silicates ("deweylite"/"garnierite") in faulted peridotites of New Caledonia: II. Petrography and chemistry of white and green clay infillings

Gabrielle Dublet

This study, which complements a first mineralogical work, presents detailed petrographic and chemical data on the sequences of clay infillings commonly found in serpentine veins of reactivated faults from the New Caledonian peridotite formation. Chemical t ...

Catalytic supercritical water gasification: Interaction of sulfur with ZnO and the ruthenium catalyst

Christian Ludwig, Frédéric Vogel, Gaël Peng

Continuous catalytic supercritical water gasification (CSCWG; 400 degrees C, 28 MPa) of microalgal biomass (Chlorella vulgaris) was carried out at the microalgae production site of ZHAW in Wadenswil (Switzerland) non-stop over a period of 100 h. Characteri ...

A dimerization interface mediated by functionally critical residues creates interfacial disulfide bonds and copper sites in CueP

Matteo Dal Peraro, Luciano Andres Abriata

CueP confers bacterial copper resistance in the periplasm, particularly under anaerobic conditions, through an unknown mechanism. The only available structure and limited solution data suggest that CueP forms noncovalent timers in solution, whereas sequenc ...

Method for recovering silicon from sawing waste

Patrik Willi Hoffmann

A method for separating and recovering silicon debris from sawing waste is characterized in that it comprises the following steps: - treating the sawing waste so as to deoxidize the silicon debris in a manner that reduces their surface energy, - applying t ...

Etude des morphologies de solidification dans les alliages aluminium-zinc

Frédéric Claude Denis Dreyer

Aluminum zinc alloys constitute an important class of wrought alloys, the so-called 7000 series, and are also widely used as anti-corrosion coatings of steel sheets. They are also interesting from a more fundamental point of view because zinc, a hexagonal ...
