    摘要: The invention provides a process for producing methanol, which process comprises contacting H2 and CO2 with a solid catalyst, at a temperature of from 200° C. to 300° C. and at a reactant pressure of from 150 bar to 500 bar, which reactant pressure is the sum of the partial pressures of the H2 and the CO2, wherein: the molar ratio of the H2 to the CO2 is x:1.0, wherein x is from 2.5 to 3.5; and the catalyst comprises: (i) a copper component which is Cu, CuO or Cu2O, or a mixture of two or three thereof, and (ii) ZnO, wherein the catalyst has a specific copper surface area of at least 10 m2/g-catalyst.

    摘要: The invention refers to a nanoparticle comprising (i) a core comprising a first population of quantum dots (QDs) embedded in silica, (ii) a shell comprising a second population of QDs embedded in silica, (iii) at least one biomolecule selected from a peptide, a nucleic acid, a carbohydrate or a lipid which comprises a cleavage site that is susceptible of being cleaved by a hydrolytic enzyme, said biomolecule being bound to the surface of the shell through a moiety, and (iv) a photoluminescent label for each biomolecule, wherein the label is bound to the part of the biomolecule which detaches from the nanoparticle after cleavage of said biomolecule by a hydrolytic enzyme, wherein the first and second QD populations have different maximum photoluminescence emission wavelengths, and only the second QD population is susceptible of producing Forster resonance energy transfer (FRET) with the photoluminescent label.
