Water retention behaviour of compacted bentonites: experimental observations and constitutive model

Bentonite-based materials are studied as potential barriers for the geological disposal of radioactive waste. In this context, the hydro-mechanical behaviour of the engineered barrier is first characterized by free swelling conditions followed by constant ...

Competing effects of volume change and water uptake on the water retention behaviour of a compacted MX-80 bentonite/sand mixture

Anne-Catherine Adolphine M Dieudonné

Bentonite-based materials have been studied as potential barriers for the geological disposal of radioactive waste. In this context, the hydro-mechanical behaviour of the engineered barrier is first characterized by free swelling conditions (as a consequen ...

Assessment of phase-field-crystal concepts using long-time molecular dynamics

William Curtin, Kristopher Learion Baker

The ability of the phase-field-crystal (PFC) model to quantitatively predict atomistic defect structures in crystalline solids is addressed. First, general aspects of the PFC model are discussed within the context of obtaining quantitative results in solid ...

Bipolar Conductance Switching of Single Anthradithiophene Molecules

Klaus Kern, Hagen Klauk, Uta Schlickum, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Single molecular switches are basic device elements in organic electronics. The pentacene analogue anthradithiophene (ADT) shows a fully reversible binary switching between different adsorption conformations on a metallic surface accompanied by a charge tr ...

Impact of the urbanization process on connectivity and genetic diversity - a spatially explicit simulation approach

Stéphane Joost, Estelle Rochat, Ivo Widmer

Urbanization leads to fragmentation, degradation or loss of natural environments and reduces connectivity between remaining habitat patches. This affects dispersal and establishment of species and their genes and might have adverse effects on biodiversity ...

Monte Carlo Modeling of Crystal Channeling at High Energies

Philippe Jean Schoofs

Charged particles entering a crystal close to some preferred direction can be trapped in the electromagnetic potential well existing between consecutive planes or strings of atoms. This channeling effect can be used to extract beam particles if the crystal ...

Spectral series of the Schrodinger operator with delta-potential on a three-dimensional spherically symmetric manifold

Tudor Ratiu

The spectral series of the Schrodinger operator with a delta-potential on a threedimensional compact spherically symmetric manifold in the semiclassical limit as h -> 0 are described. ...

Monte Carlo modeling of crystal channeling at high energies

Alessio Ferrari, Philippe Jean Schoofs, Francesco Cerutti

Channeling in bent crystals is becoming a reliable and efficient technique for collimating beams. At CERN, the installation of crystals in LHC is under scrutiny by the UA9 collaboration with the goal of investigating if they are a viable option for the col ...
