Simple abrasivity testing has been carried out on a sequence of arkosic and sub-arkosic sandstones, siltstones and mudstones with dominant sericite and ferruginous cements. Abrasivity classifications systems have been proposed by Thuro & Käsling (2009), wh ...
Monodisperse cubic spinel iron oxide magnetic nanoparticles with variable sizes were prepd. following a multi-injection seeded-growth approach. As expected from such a known synthetic route, all samples were characterized by narrow size distributions, and ...
The Molasse is a geologic formation which covers most part of the Swiss plateau. This sedimentary formation is constituted by various types of rock such as sandstones, marls (claystones) and siltstones. The Rock Mechanics Laboratory (LMR) of the EPFL has a ...
An attempt has been made to achieve the crystallization of silicon thin film on metallic foils by long pulse duration excimer laser processing. Amorphous silicon thin films (100 nm) were deposited by radiofrequency magnetron sputtering on a commercial meta ...
We present an inverse modeling procedure for the estimation of model parameters of sedimentary basins subject to compaction driven by mechanical and geochemical processes. We consider a sandstone basin whose dynamics are governed by a set of unknown key qu ...
An important microstructural aspect of the early hydration of Portland cement (K) is the formation of a shell of hydration products around cement grains. There is, at present, limited information on the mechanism of formation of the shell and of the chemis ...
In this technical note we compare silica gel grains and quartz sand as sediment media for vegetation root growth in laboratory experiments for ecohydrology and ecohydraulics. Silica gel grains become quite transparent when saturated with water. This would ...
Hematite is a semiconducting mineral with a role in natural photoelectrochemical processes, and has been studied from the viewpoint of solar energy utilization. Hematite is an anisotropic conductor, with faster conduction parallel to (001) planes. Flatband ...
The purpose of this study is to investigate the role of filling materials (e.g., quartz sand and kaolin clay) in the interaction between a P-wave and a rock fracture. The specific fracture stiffness reflects the seismic response of a filled fracture, while ...
We introduce a simple solution-based strategy to decouple morphological and functional effects of annealing nanostructured, porous electrodes by encapsulation with a SiO2 confinement scaffold before high temperature treatment We demonstrate the effectivene ...
