Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach. Bot

International audience; Ball milling techniques were used to introduce both fluorine and catalytic transition metals (Fe, Ni) into MgH2 nanograined powders. XRD was carried out to follow the structural evolution upon milling, whereas the thermal stab

The redox mechanism of γ-MnO2 was studied in KOH electrolytic solutions of increasing concentration ranging from 1 to 9N. The reduction process of the first cycle, carried out at i = 0.33 Am−2, shows a one-stage reduction in KOH 1N and two stage-r

Raman scattering (RS) and Fourier transform-infrared (FT-IR) spectroscopy have been applied to the structural characterisation of manganese dioxides (MDOs). A variety of synthetic battery-grade MDOs are investigated for comparison to the natural phas
