Role of filling materials in a P-wave interaction with a rock fracture

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 ...

Inverse modeling of geochemical and mechanical compaction in sedimentary basins through Polynomial Chaos Expansion

Lorenzo Tamellini

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 ...

Abrasivity test results from Lao-PDR: verification of the CAI-LCPC abrasivity classification

Jean-François Mathier

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 ...

Mechanical characteristics of Swiss molassic formations

Jean-François Mathier, Mustapha Gencer

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 ...

Excimer laser crystallization of amorphous silicon on metallic substrate

Cyril Cayron

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 ...

Correlating Magneto-Structural Properties to Hyperthermia Performance of Highly Monodisperse Iron Oxide Nanoparticles Prepared by a Seeded-Growth Route

Raffaella Buonsanti, Alessandro Genovese

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 ...

Decoupling Feature Size and Functionality in Solution-Processed, Porous Hematite Electrodes for Solar Water Splitting

Kevin Sivula, Jérémie Minh-Châu Brillet

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 ...

Microstructural development of early age hydration shells around cement grains

Karen Scrivener, Emmanuel Gallucci, Prakash Chandra Mathur

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 ...

An experimental comparison of silica gel and quartz sand grains as sediment media for growing vegetation at the laboratory scale

Paolo Perona, Peter Molnar, Zhe Jiang

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 ...

Anisotropic photocatalytic properties of hematite

Michael Graetzel, Ilkay Cesar

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 ...
