A Simple Liquid-Liquid Biphasic System for Hydrogen Peroxide Generation

Hubert Girault, Gunther Wittstock

Although electron transfer reactions at liquid liquid interfaces have been thoroughly studied in the presence of deliberately added potential determining ions or phase transfer catalysts, little is known about these reactions in the absence of the above sp ...

Towards pre-dimensioning of natural gas networks on a web-platform

Gaëtan Cherix, Massimiliano Capezzali, Pablo Puerto, Mathias Franz Pernet

The MEU GIS-enabled web-platform has been developed in close collaboration with four Swiss cities: it enables detailed monitoring and planning for both energy demand and supply at individual building and neighborhood level (http://meu.epfl.ch). This web-pl ...

Magnetic anisotropy of the spin tetramer system SeCuO3 studied by torque magnetometry and ESR spectroscopy

Helmuth Berger

We present an experimental study of macroscopic and microscopic magnetic anisotropy of a spin tetramer system SeCuO3 using torque magnetometry and ESR spectroscopy. Large rotation of macroscopic magnetic axes with temperature observed from torque magnetome ...

Hydration and dimensional stability of calcium aluminate cement based systems

Julien Bizzozero

Calcium aluminate cements (CAC) are often used in combination with calcium sulfate and Portland cement for special applications where rapid setting, rapid drying and shrinkage compensation are required. A growing fraction of the clinker, which has the high ...

On the relevance of volume increase for the length changes of mortar bars in sulfate solutions

Karen Scrivener, Barbara Lothenbach, Wolfgang Kunther

The ingress of sulfate ions into cementitious materials leads to the formation of ettringite, gypsum and other phases. The increase in solid volume through the formation of these phases is often assumed to be the only reason for expansion. In this paper we ...

Protein-nanoparticle interactions: the effects of surface compositional and structural heterogeneity are scale dependent

Francesco Stellacci, Randy Patrick Carney

Nanoparticles (NPs) in the biological environment are exposed to a large variety and concentration of proteins. Proteins are known to adsorb in a 'corona' like structure on the surface of NPs. In this study, we focus on the effects of surface compositional ...

Water Injection in isothermal co-rotating scroll compressor and turbine

Roberto Passini

This project deals with the study of a quasi-isothermal scroll compression/expansion obtained by spray injection of water. The spray injection process is first described from the theoretical point of view as it concerns the droplets formation and breakup p ...
