    摘要： A method for coloring of cellulose in a supercritical CO2 medium by an uncharged hydrophobic dye, including at least the steps including of: (i) provision of cellulose fibers, (ii) placing the cellulose fibers in the presence of: a) an effective quantity of at least one uncharged mono organo-urea primer of formula R—NH—CO—NH2, where R represents a linear or branched, saturated or unsaturated, hydrocarbon chain possessing at least 3 carbon atoms, or a saturated or unsaturated cyclic hydrocarbon radical, which is bonded directly or via a methylene or ethylene group to a nitrogen atom, and if appropriate substituted under conditions conducive to the forming of a covalent carbamatic bond between the cellulose and the molecules of the organo-urea; and b) at least one hydrophobic dye in a supercritical CO2 medium, under conditions conducive to the immobilization of the dye on the fibers.

    摘要： A process for preparing hollow particles of aluminosilicates having a spherical shape of allophane type which are hybrid at the core, comprising: (a) having, at ambient temperature, an aqueous medium containing at least one aluminum precursor and one silicon alkoxide in an Al/Si molar ratio varying from 1 to 3, (b) carrying out, with stirring, the alkaline hydrolysis of said medium with gradual addition of at least one base in a base/Al molar ratio of 2.3 to 3, (c) maintaining, on conclusion of the addition of all of said base, stirring at ambient temperature until said medium is obtained in the clear state, and (d) heating the solution obtained at a temperature varying from 50 to 150° C. for 2 to 8 days, the combined stages (a) to (d) are carried out within a reactor consisting of a material which is chemically inert with respect to the reactants and expected aluminosilicate.

    摘要： The invention relates to a thermally conducting capsule which has a core-shell structure and in which the core, which is surrounded by a tight single-layer or multilayer shell, is loaded with at least one phase change material (PCM). The invention is characterized in that the capsule also contains particles made of an additional conducting material at least in the shell, said particles made of the additional conducting material having a thermal conductivity greater than 100 W/m/K. The invention further relates to the use of said capsule in a heat-conducting material, in particular a thermal fluid, in order to modulate the heat capacity thereof.
