Organic-inorganic hybrid nanofibres comprising two phases: A membrane and an electrode comprising said nanofibres. A fuel cell comprising said membrane and/or said electrode. A method of preparing said nanofibres by electrically assisted extrusion (electrospinning).

Organic-inorganic hybrid nanofibres having a mesoporous inorganic phase, preparation thereof by electrospinning, membrane, electrode, and fuel cell

The invention relates to the use of nanoparticles of at least one oxide of at least one transition metal doped with a rare earth element, particularly YVOEunanoparticles obtained through a sol-gel process, as a sensitive material in a chemical sensor for detecting peroxide-compound vapors. The material is used in a liquid process, in a spray of the initial sol, or in a solid thin film after being deposited on a substrate. The inorganic, fluorescent character of the nanoparticles makes it possible to obtain a sensitive material for an optical sensor that has good performance stability over time. The intended uses are the detection of explosives or explosive precursors, particularly peroxides, the control or monitoring of atmospheric pollution and ambient-air quality, and the monitoring of industrial sites.

Use of transition-metal oxide nanoparticles as sensitive materials in chemical sensors for detecting or assaying vapors of target molecules

The present invention relates to polymers comprising phenylene units, at least one of which bears a phenylene side group substituted with a perfluoro group or chain, which itself bears an &#x2014;SOH, &#x2014;POHor &#x2014;COH group. Use of this polymer to make fuel cell membranes.

Polyphenylene-type polymers, preparation method thereof, membranes and fuel cell device comprising said membranes
