Polyelectrolyte complex membrane formation has been studied, online, using the synthetic boundary technique of an Optima XL-I anal. ultracentrifuge. This recent method, established by the first author, has now been evaluated concerning its sensitivity to m ...
The prepn. and characterization of two novel dinuclear tantalum hydride complexes featuring bridging silanimine ligands are reported. The reaction of Cp*(ArN:)Ta[Si(SiMe3)3]H (Cp* = h5-C5Me5; Ar = 2,6-iPr2C6H3) with PhSiH3 resulted in formation of [Cp*(ArN ...
Although the majority of soils are unsaturated, their mechanical behaviour is still not well defined. This dissertation presents first an experimental study of an unsaturated silt and then proposes an elasto-plastic constitutive law to model the behaviour ...
We study the energy barrier for flux entry of a geometric origin in type-I superconducting strips using magneto-optical observations of the flux structure. The magnetic field is applied perpendicularly to the broad surface and, optionally, a dc current is ...
We report on the experimental observation of excitonic molecules (biexcitons) in high-quality V-shaped quantum wires. By means of spatially resolved near-field photoluminescence spectroscopy, first we unambiguously isolate excitons with a one-dimensional c ...
The mechanical properties of 590 MeV proton irradiated pure cl-iron have been investigated after irradiation at 320, 420 and 520 K to doses between 10(-5) and 10(-1) dpa. For comparison, corresponding rests were carried out on unirradiated iron specimens. ...
A detailed study is presented on AlInAs/InGaAs/InP composite channels. These devices combine the advantages of high mobility at low voltages and high electric field operations thanks to the use of a composite channel formed by a thin InGaAs layer and a dop ...
Glial cell line-derived neurotrophic factor (GDNF) holds great promise for the treatment of Parkinson's disease. In humans, its intracerebroventricular administration leads to limiting side effects. Direct parenchymal delivery using mechanical means, or ce ...
The purpose of the present work was to examine the effect of different Ti-6Al-4V surface treatments on osteoblasts behaviour. Previous work in this laboratory has demonstrated that an ageing treatment reduces metal ion release from this alloy compared to s ...
Dyslipidemias and insulin resistance often present simultaneously, as in familial combined hyperlipidemia (FCHL), and therefore may have a common genetic background. In our previous study the Pro12A1a substitution of peroxisome proliferator receptor gamma ...
