16 p, 1.3 MB The effect of surface charge and wettability on H2O self diffusion in compacted clays / Schampera, Birgit (Leibniz University Hannover. Institute of Soil Science) ; Dultz, Stefan (Leibniz University Hannover. Center for Solid State Chemistry and New Materials)
Organo-clays are of interest in the modification of anion transport properties in engineered barriers. In the present study, surface charge and wettability were assessed for tracking changes in the effective diffusion coefficient (D) by the formation or suppression of bound HO layers on the external surfaces of clays.

(Chalmers University of Technology (Göteborg, Suècia)) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
We present an overview of the electrical, mechanical, and thermal properties of polycrystalline graphene. Most global properties of this material, such as the charge mobility, thermal conductivity, or Young's modulus, are sensitive to its microstructure, for instance the grain size and the presence of line or point defects. [...]

5 p, 625.2 KB Drift-diffusion model for single layer transition metal dichalcogenide field-effect transistors / Jiménez Jiménez, David (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; American Physical Society
A physics-based model for the surface potential and drain current for monolayertransition metal dichalcogenide (TMD) field-effect transistor is presented. Taking into account the two-dimensional (2D) density-of-states of the atomic layer thick TMD and its impact on the quantum capacitance, a model for the surface potential is presented. [...]
