Abstract: A method for extracting and separating at least one component from a LED, the LED including at least one metal, at least one phosphor and at least one layer including polydimethylsiloxane. Also, an LED having at least one layer including polydimethylsiloxane, wherein the at least one layer comprising polydimethylsiloxane is depolymerized by the action of a solution including a solvent and a fluorine salt.

Abstract: The invention concerns compounds of formula (I) wherein: A represents R1 or (O)R1 where R1 represents an alkyl group comprising 1 to 30 carbon atoms, linear or branched, saturated or unsaturated, capable of being partly or totally substituted by Hal where Hal represents —Cl,—Br, or —F, and of being interrupted by one or several units selected among —O—,—S—,—C(O)—,—NR3C(O)—, —Ph(R4)n— and —CH2—CH2—O)n′—, wherein R3 represents or —CH2)n″—CH where n″=0 to 17; R4 represents, —CH3,—CH2H5,—C3H7 and n=0 to 4 and n′=1, 2, or 3, or R1 represents a cyclanic radical with diterpene or triterpene root; and R2 represents a C1−C11 linear or branched alkyl group.

Abstract: The invention concerns a fungicidal or fungistatic composition comprising, in combination, at least one glycolytic enzyme and its substrate and/or oligomers thereof; a process for preparing said compositions; and their use.
