Abstract: Cork stoppers are treated by subjecting the cork to an electrochemical dehalogenation by electrolysis.

Abstract: A detector system for detecting a chemical substance, the system being of the type comprising a measurement sensor for selectively sensing the chemical substance to be detected, and a measurement unit associated with the measurement sensor for the purpose of being connected to a processor unit to determine whether said chemical substance for detection is present or absent. The measurement sensor comprises an olfactory neuron selected for selectively sensing the chemical substance to be detected, and the olfactory neuron is secured to a support in order to co-operate with the measurement unit.

Abstract: The invention concerns a high power capacitor ideally polarizable consisting of a positive electrode (2) and its current collector (4), a negative electrode (3) and its current collector (5), said electrodes comprising a carbon containing material with high specific surface area, a separator (6) and a non-aqueous liquid electrolyte impregnating said separator and said electrodes. The invention is characterised in that the non-aqueous liquid electrolyte is an organic solution of a sodium or potassium or alkalin-earth metal salt, on their own or mixed in a solvent containing an acid.
