Developing a high capacity axis translation apparatus for gas shale testing

Lyesse Laloui, Alessio Ferrari, Jinwoo Kim

Gas shales are usually partially saturated due to hydrocarbon generation and often have a low in-situ degree of saturation less than 40 %. During stimulation, substantial fluid imbibition into the formation occurs due to high suction. Recent research on th ...

High-fat diet consumption alters energy metabolism in the mouse hypothalamus

Rolf Gruetter, João Miguel das Neves Duarte, Antoine Timothée Cherix, Blanca Lizarbe Serra

BACKGROUND/OBJECTIVES: High-fat diet consumption is known to trigger an inflammatory response in the hypothalamus, which has been characterized by an initial expression of pro-inflammatory genes followed by hypothalamic astrocytosis, microgliosis, and the ...

Turbocompressors for Domestic Heat Pumps – A Critical Review

Jürg Alexander Schiffmann, Jean-Baptiste Carré

Small-scale, oil-free radial compressors on gas lubricated bearings represent a promising alternative to state-of-the-art compressor technology for driving domestic sized heat pumps. The inherent characteristics of turbocompressors manage to fit the heat p ...

Working fluid charge reduction. Part II: Supercritical CO2 gas cooler designed for light commercial appliances

John Richard Thome, Jackson Braz Marcinichen

The present study focused on the thermal hydraulic performance improvement of a CO2 gas cooler with the principal goal of reducing its volume, and consequently the necessary charge of the working fluid. To achieve this compactness, the leading methods for ...

Synergistic effect of carboxylic and amine ligands on the synthesis of CdSe nanocrystals

Martinus Adela Maria Gijs, Virendra Kumar Parashar

We demonstrate the drastic improvement in absorbance and photoluminescence (UV-PL) of CdSe nanocrystals (NCs) upon adding both a carboxylic acid and an amine ligand to the cadmium acetate green chemistry source. We combined carboxylate complexes of lauric ...

Hydrophobic Meshes for Oil Spill Recovery Devices

Francesco Stellacci

Widespread use of petrochemicals often leads to accidental releases in aquatic environments, occasionally with disastrous results. We have developed a hydrophobic and oleophilic mesh that separates oil from water continuously in situ via capillary action, ...

Flow boiling characteristics and flow pattern visualization of refrigerant/lubricant oil mixtures

John Richard Thome

A comprehensive review of flow boiling characteristics and flow pattern visualization of refrigerant/lubricant oil mixtures is presented in this paper. First, various parameters influenced by the lubricant oil in convective boiling of refrigerants, such as ...

Advanced hydro-mechanical coupling for unified constitutive modelling of unsaturated soils

Lyesse Laloui, Mathieu Nuth

A new unified constitutive hydro-mechanical model named ACMEG-s is formulated to improve modelling of unsaturated soils in free or constrained conditions. Indeed, due to particular mechanical and hydraulic boundary conditions, some natural and engineered f ...

Liquid-core capsules as a tool in biotransformations

Anne Wyss

The aim of this thesis was to develop a new type of liquid-core capsules obtained by co-extrusion using the laminar jet break-up technique. These capsules, composed of an organic phase as the core and a hydrogel membrane, were meant to be applied as an in- ...
