A negative electrode active material for a lithium-ion battery has the following formula (I): Li1-xOHFe1+xS (I). x varies from 0.00 to 0.25, preferably from 0.05 to 0.20.

Negative electrode active material based on iron and lithium hydroxysulfide

The present invention pertains to a process for preparing particles of rare earth sulfide comprising the steps of:&#x2014;preparing a reaction mixture comprising at least one compound comprising at least one rare earth element (A) and at least one alkali metal sulfide (B),&#x2014;submitting said reaction mixture to a mechanical stress so as to cause a chemical reaction that produces the particles of rare earth sulfide.

Mechanochemical synthesis of rare earth sulfides

This invention relates to a method to manufacture a chip to detect the direct conversion of X-rays. It also relates to a direct conversion detector for X-rays using such a chip and dental radiology equipment using at least one such detector. The method to manufacture the wafer comprises a step for applying pressure () to a powdered polycrystalline semiconductor material and a step for heating (-) during a set time period. It comprises a preliminary step for providing an impurity level of at least 0.2% in the polycrystalline semiconductor material.

Method for manufacturing a sensor chip for the direct conversion of X-rays, a sensor for the direct conversion of X-rays and the dental radiology apparatus for using such a sensor

The invention relates to a material comprising at least one compound having formula BiMAgM'OSM&#x2033;, the methods for producing said material and the use thereof as a semiconductor, such as for photovoltaic or photochemical use and, in particular, for supplying a photocurrent. The invention further relates to photovoltaic devices using said compounds.

Mixed oxides and sulphides of bismuth and silver for photovoltaic use

The invention relates to biocidal granules composed of a mineral core coated with at least one porous inorganic layer including at least one organic compound capable of limiting or preventing the growth of microorganisms, in particular of algae. The invention also relates to a sol-gel process for the preparation of the biocidal granules and to the use of these biocidal granules in building materials, in particular shingles and siding coatings.
