We grew epitaxial SrTiO3 (STO) thin films on (001) LaAlO3 substrates via a two-step procedure using pulsed laser deposition and studied them with transmission electron microscopy in plane-view and cross-sectional samples. We found that partial misfit dislo ...
Nowadays the orientation maps of polycrystalline material are necessary for a better understanding of, for example, the formation of voids in the interconnects of modern electronic devices. As new generation of devices has dramatically reduced in size, new ...
Epitaxial lithium tantalate (LiTaO3) thin films were grown on the hexagonal plane of sapphire substrates by metal organic chemical vapor deposition. Two crystallographic variants, related to each other by 180° rotation around the c axis, as well as non-180 ...
Two strategies have been proposed in CSCL to foster effective collaboration: structuring the learning scenario by means of collaboration scripts and monitoring interactions among participants in order to detect and regulate potential deviations from the in ...
This paper presents a validation of numerical simulations in case of a forced oscillating hydrofoil. As a representative case study for vibrating blade in hydraulics machines, a 2D NACA 0009 oscillating hydrofoil is considered. Pressure coefficients from e ...
This paper presents an investigation of the hydro elastic behavior of vibrating blades in hydraulic machines, which is of strong interest for turbo machinery applications. As a representative case study for vibrating blade in hydraulic machines, a NACA 000 ...
This paper investigates the effectiveness of voluntary approaches in a comparative case study on European and Swiss climate legislation. Voluntary approaches are known to be less environmentally effective and economic efficient than other climate policy in ...
We calculate from first principles the nonlinear piezoelectric response of ferroelectric PbTiO3 for the case of a polarization-enhancing electric field applied along the tetragonal axis. We focus mainly on the case of fixed in-plane lattice constants, corr ...
This book examines experimental design methodologies in the field of architecture and their implementation in academic settings. Theoretical considerations by guest essayists and numerous examples of conceptual designs complement our holistic approach to t ...
[1] Fluid flow in deformable porous media is of interest in many areas of hydrology, geophysics, and environmental engineering at scales ranging from individual pore to field scale. With increasing interest in pore-scale hydraulics, there is also the need ...
