Abstract: The invention relates to a passive optical limiter having a nonlinear material capable of switching in a predetermined optical band from a transparent state to an opaque state as a function of the power of an incident laser beam. The nonlinear material is an organic dye which comprises molecules derived from 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene into which a nitrogen atom is inserted at the meso position, referred to as aza-bodipy molecules, and which have conjugated ? chains functionalized so as to exhibit absorption for two photons around an incident beam wavelength lying between 1.45 ?m and 1.6 ?m.

Abstract: The present invention relates to a process for manufacturing alkanes, comprising, as main stage, a reaction resulting from bringing methane into contact with at least one other starting alkane (A) in the presence of a catalyst based on a metal M capable of catalyzing a metathesis of alkanes. The reaction results in the formation of at least one or two final alkanes (B) having a number of carbon atoms less than or equal to that of the starting alkane (A) and at least equal to 2. Preferably the catalyst comprises a hydride of a metal M grafted to and dispersed over a solid support. The metal M may be chosen from transition metals, lanthanides and actinides. The present invention also relates to the use of a catalyst capable of catalyzing a metathesis of alkanes in 3 reaction resulting from bringing methane into contact with at least one other starting alkane (A).

Abstract: A process for the manufacture of alkanes comprising a cross-metathesis reaction between at least one starting alkane (A) and one organometallic compound (B) fixed to an inorganic support and comprising a metal bonded to at least one hydrocarbon-comprising radical. The reaction leads to the formation of at least one other alkane (C) which is a higher or lower homologue of the starting alkane (A), by cleavage of the hydrocarbon-comprising radical with the metal of the organometallic compound (B) and recombination of the radical with at least one other radical originating from a cleavage of the starting alkane (A). The metal of the compound (B) preferably is selected from transition metals, lanthanides and actinides, and the hydrocarbon-comprising radical of the compound (B) preferably is selected from alkyl, alkylidene and alkylidyne radicals.

Abstract: A method, apparatus, and article of manufacture for allowing a particle to follow a path. A one dimensional path having an attraction force which affects particles is embodied in N-dimensional space, such as two dimensional or three dimensional space. The attraction force is then applied to the particle in the direction of the path, where the magnitude of the force corresponds to the distance between the particle and the path. The attraction force may optionally be applied for only a percentage of the path length.
