Atomic Force Measurements of Hydrophobic Interactions
This semester project comes within the scope of studies at the nanometre scale. The experimental techniques used in this work are related to atomic force microscopy, which gives a direct access to the topography and forces of the studied systems. The goal ...
2012Influence of the stress field due to pressurized nanometric He bubbles on the mobility of an edge dislocation in iron
Robin Schäublin, Seyed Masood Hafez Haghighat
Voids and He bubbles are strong obstacles to dislocation, which induce hardening and loss of ductility. In Fe, molecular dynamics simulation is used to investigate the basic mechanisms of the interaction between a moving edge dislocation and a void or He b ...
Taylor & Francis2010Communications: Evaluation of the nondiabaticity of quantum molecular dynamics with the dephasing representation of quantum fidelity
Jiri Vanicek, Tomas Zimmermann
We propose an approximate method for evaluating the importance of non-Born–Oppenheimer effects on the quantum dynamics of nuclei. The method uses a generalization of the dephasing representation (DR) of quantum fidelity to several diabatic potential energy ...
American Institute of Physics2010Extraction of haemoglobin from human blood by affinity precipitation using a haptoglobin-based stimuli-responsive affinity macroligand
Affinity precipitation was compared to affinity chromatography and batch adsorption as the final purification step in a protocol for the isolation of haemoglobin from human blood. Haptoglobin was the affinity ligand. The first steps on the process were rea ...
2008Interactive spaces
Jeffrey Huang, Muriel Waldvogel
How do conceptions of space change with the infiltration of new elements of interactivity into our surroundings? What are the effects of digitalization on typological, tectonic and ornamental changes in contemporary architecture and cities? What are the ne ...
Springer-Verlag New York, Ms Ingrid Cunningham, 175 Fifth Ave, New York, Ny 10010 Usa2008Computer simulation of ion-selective membrane electrodes and related systems by finite-difference procedures
A simple but powerful numerical simulation for analyzing the electrochemical behavior of ion-selective membranes and liquid junctions is presented. The computer modeling makes use of a finite-difference procedure in the space and time domains, which can be ...
2007Electronic-enthalpy functional for finite systems under pressure
Nicola Marzari, Matteo Cococcioni
We introduce the notion of electronic enthalpy for first-principles structural and dynamical calculations of finite systems under pressure. An external pressure field is allowed to act directly on the electronic structure of the system studied via the grou ...
2005Electrolummescence of asymmetric coupled GaAs/AlGaAs V-groove quantum wires
Elyahou Kapon, Alok Rudra, Marc-André Dupertuis, Klaus Leifer
We have studied systems of asymmetric coupled GaAs V-groove quantum wires, in which the electrons and holes are injected into different wires. Our experimental results indicate efficient electron and hole tunneling, despite a 7 nm thick AlGaAs tunnel barri ...
Iop Publishing Ltd2003Supercritical calorimetry: an emerging field
Thierry Meyer, Sophie Fortini, Frédéric Lavanchy
Calorimetry (adiabatic, isothermal, differential, oscillating or acoustic) is generally based on heat-flow measurements of the studied system. Most of its applications are dedicated to kinetic-parameter detn., safety studies and process optimization, phase ...
