标题:Rapid Ether And Alcohol C-o Bond Hydrogenolysis Catalyzed By Tandem High-Valent Metal Triflate + Supported Pd Catalysts
摘要:The Thermodynamically Leveraged Conversion Of Ethers And Alcohols To Saturated Hydrocarbons Is Achieved Efficiently With Low Loadings Of Homogeneous M(Otf)(N) + Heterogeneous Pd Tandem Catalysts (M = Transition Metal; Otf = Triflate; N = 4). For Example,Hf(Otf)(4) Mediates Rapid Endothermic Ether Reversible Arrow Alcohol And Alcohol Reversible Arrow Alkene Equilibria,While Pd/c Catalyzes The Subsequent,Exothermic Alkene Hydrogenation. The Relative C-O Cleavage Rates Scale As 30 Degrees > 20 Degrees > 1 Degrees. The Reaction Scope Extends To Efficient Conversion Of Biomass-Derived Ethers,Such As Thf Derivatives,To The Corresponding Alkanes.

摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

摘要:Synthesis of nanoparticles with particle size control is provided by the method of using two different metal-containing precursors, a capping component, an optional reducing agent, and then contacting the two precursors with the capping component to form a reaction solution, which is heated to produce first and second metals-containing nanoparticles. By controlling the ratio of the concentration of the capping component to the total concentration of the two metal-containing precursors, the nanoparticles can have diameters ranging between about 1 nm to about 15 nm. A decrease in the concentration of the capping component typically increases the size of the nanoparticles. Preferred compositions include Pt and Co-containing alloy nanoparticles. Controlled synthesis of larger, about 6 nm to about 12 nm, sized nanoparticles can be achieved in a solvent-free reaction process.

摘要:The present invention relates to a method for the synthesis of semiconductor nanoparticles comprising elements of the groups IB, IIB, IIIA, IVA, VA or VIA of the periodic classification wherein the composition of the core nanoparticle is selected from the group consisting of IB-VIA, IIB-VIA, IIIA-VIA, IB-IIIA-VIA or IB-IIB-TVA-VIA, IIB-IIIA-VIA, IIB-TVA-VA or mixtures thereof, and at least one shell comprises elements of the groups IIB and VIA,, wherein in case the core composition is IIB-VIA the shell comprises at least a further element selected from the groups IB, IIIA, IVA or VA, using metal precursors comprising non- or weakly coordinating anions. It further relates to the consecutive process for the synthesis that includes first the preparation of a binary nanoparticle system then modified to make a ternary system which again can be further modified to make a quaternary system.

摘要:A direct chemical synthesis scheme for the fabrication of isotropic and anisotropic rare earth (RE) -transition metal (TM)- based permanent magnets is disclosed. The method according to the invention permits the synthesis of, e.g., particles, films and coatings with controlled particle sizes, shapes, compositions and dispersion in one reaction process. The resulting particles have desirable hard magnetic properties such as high magnetic saturation induction and coercivity at room temperature.

标题:One-pot synthesis of nanoparticles and liquid polymer for rubber applications

摘要:A method for performing a one-batch synthesis of a blend of nanoparticles and liquid polymer includes polymerizing a first monomer and optionally a second monomer in a hydrocarbon solvent to form the liquid polymer. The polymerization is terminated before completion with a quenching agent. Then a charge of polymerization initiator, and a mixture of multiple-vinyl aromatic monomer and mono-vinyl aromatic monomer are added. This causes further polymerization whereby nanoparticles are formed in situ having a core including the multiple-vinyl aromatic monomer, and a shell including the first monomer or the first monomer and the second monomer. Liquid polymer/nanoparticle blends resulting from the method and rubber compositions incorporating the blends are also disclosed.
