International audience; The shape memory alloys based on the ternary system Cu-Al-Ni are able to produce a memory effect at high temperatures. However, if the material undergoes an accidental overheating, a transformation process leads to progressive

Rubidium and cesium hydrides are not commercialized and we have set up, a few years ago, a method of synthesis at the laboratory scale. It is based on the reaction of alkali metal with hydrogen obtained by thermal decomposition of uranium hydride UH3

The intercalation of sodium-potassium alloys into graphite leads, at room temperature, to compounds close to KC8. Graphite powder fits to large amounts of the alloy: up to compositions close to MC2, but the stable state is a mixture of KC8 and alloy
