Precipitation hardening remains an important and efficient way to improve the mechanical resistance of aluminium alloys. In the case of the Al-Mg-Si system (6XXX series), a complex precipitation sequence occurs, which is greatly affected by the presence of ...
Cu-Ni-Sn alloys with Pb additions exhibit high mechanical strength at room temperature coupled with good machinability but experience a significant ductility loss above the melting point of lead. We explore here the influence of minor additions of Al, Mn, ...
Self-levelling flooring compounds (SLC) are applied in thin layers (less than 1cm) to level floors before further finishing cover such as parquet or plastic cover. They are composed of a ternary binder system based on Portland cement (PC), calcium aluminat ...
Context. Since 1998, a planet-search program around main sequence stars within 50 pc in the southern hemisphere has been carried out with the CORALIE echelle spectrograph at La Silla Observatory. Aims. With an observing time span of more than 14 years, the ...
An important mode of hydration of Ordinary Portland cement (OPC) is via the formation of a shell of hydration products around cement grains. It has been shown so far that shells form not only in OPC but also around C3A grains in a mixture of alite, C3A and ...
After a fracture, fixing a plate to a broken bone can be problematic if the bone suffers of osteoporosis. In order to find a solution to increase bone density around the plate screws, one solution is to insert a drug-delivering bone plug that inhibits bone ...
One main barrier to the acceptability of façade use of solar thermal collectors is their black appearance and the visibility of piping or absorber irregularities through the glazing. To facilitate façade integration, a project was set up to develop selecti ...
Classical Darcy's law assumes that the intrinsic permeability of porous media is only dependent on the micro-geometrical and structural properties of the inner geometry of the medium. There are, however, numerous experimental evidences that intrinsic perme ...
NWA 1240 is an unusual eucrite recently recovered in Morocco as a single stone of 98 g. It is an unbrecciated greenish-brown rock nearly devoid of fusion crust. It displays porphyritic texture consisting of skeletal hollow low-Ca pyroxene phenocrysts set i ...
This abstract presents a perform study on SOLERO, a new and innovative rover concept for regional mobility on planetary surfaces. A rover is the most suited element to bring scientific instrument to a specific site in order to examine geology, mineralogy o ...
