Single crystal films of Gd and Nd were grown by MBE techniques using the LaMBE facility in Oxford. The thickness of the layers was 5000 Angstrom and the mosaic spread about 0.2-0.3 degrees. Some of the layers were hydrogenated by KTH in Stockholm to obtain ...
We consider spherically symmetric higher-dimensional solutions of Einstein's equations with a bulk cosmological constant and n transverse dimensions. In contrast to the case of one or two extra dimensions we find no solutions that localize gravity when n ≥ ...
The effect of the bulk microstructure (grain size distribution, grain boundary length) on the oxygen transport properties of permeation membranes is investigated in this work. For this purpose, La0.5Sr0.5FeO3-? samples with different microstructures have b ...
Research and development in the field of electroceramics is driven by technology and device applications. It includes research on a broad spectrum of inorganic materials, and it covers all scales from the level of the crystalline lattice to that of final d ...
This paper is the second part of a description of the online monitoring through ultrasound propagation velocity measurements of styrene polymn. in a continuous recycle reactor. A set of calibrations and a simple math. model are proposed to interpret the ex ...
The nucleation and growth of microcracks in elastic lamellar microstructures is studied numerically. The analyses are carried out within a framework where the continuum is characterized by two constitutive relations: one relating the stress and strain in t ...
We show that the two-dimensional quantum confined Stark effect in a semiconductor quantum wire can display novel behaviour, i.e. wave function splitting and cascading. No analog to these phenomena can be found in bulk material or quantum wells. The consequ ...
In many miniature systems for positioning and especially in microrobotics the assembly of the components becomes difficult. At sizes of systems of a few cm2 not only the assembly becomes more difficult, downscaling also means that single parts become more ...
The uptake of zinc by cerebellar rat cultures upon exposure to ZnCl2 solutions was comparatively investigated using two well known condensed matter physics techniques: synchrotron photoelectron spectromicroscopy and inductively coupled plasma atomic emissi ...
There is some confusion in the literature about the material parameters for eutectic tin-lead solder. This is mainly caused by the varying parameters under which the samples are processed and treated prior to testing, which lead to different microstructure ...
