The invention relates to a memristive element (M) formed by: a first electrode (); a second electrode (); and an active region () making direct electrical contact with said first and second electrodes, characterized in that said active region essentially consists of a thin film of an insertion compound containing at least one alkali metal, said compound being an oxide or chalcogenide of at least one transition metal and being able to conduct both electrons and ions. Non-volatile electronic memory formed from a plurality of such memristive elements.

Memristive element and electronic memory based on such elements

A device for mass storage of information, the device comprising: a substrate (); an electrically-conductive tip () for atomic force microscopy located above the surface () of said substrate () in electrical contact therewith; and a voltage generator () for applying a potential difference between said tip () and said substrate (); the device being characterized in that: said substrate () has a surface () of a material presenting electrical conductivity that is both electronic and ionic in nature; and in that said generator () is adapted to apply a potential difference that is sufficient to induce a redox reaction of said material that modifies the surface electrical conductivity of the substrate (). The use of such a device () for mass storage of information.

Disclosed is an organic material with a very narrow electronic spin resonance (ESR) line. This material is formed by a 1, 2, 7, 8-tetrahydrocyclopentataperylene salt which may have, advantageously, undergone a heat treatment. The material can be applied to the fabrication of probes for gaussmeters and magnetometers.

The invention relates to a process for preparing a polyalkyl perylene which consists in subjecting the corresponding polyalkyl 1,1'-dinaphthalene derivative to a cyclodehydrogenation reaction, by means of an alkali metal. It also relates to the polyalkyl perylene obtained, and to the organic material derived therefrom exhibiting an electron spin resonance spectrum.
