The invention relates to a method for manufacture of hydrocarbon fuels and oxygenated hydrocarbon fuels such as alkyl substituted tetrahydrofurans such as 2,5-dimethyltetrahydrofuran, 2-methyltetrahydrofuran, 5-methylfurfural and mixtures thereof. The method generally entails forming a mixture of reactants that includes carbonaceous material, water, a metal catalyst and an acid reacting that mixture in the presence of hydrogen. The reaction is performed at a temperature and for a time sufficient to produce a furan type hydrocarbon fuel. The process may be adapted to provide continuous manufacture of hydrocarbon fuels such as a furan type fuel.

A microstructure includes a catalyst region, and a non-catalyst region proximate to the catalyst region. The catalyst region induces a chemical reaction of a fluid component when the microstructure is located within a fluid medium containing the fluid component. The chemical reaction induces relative motion between the fluid medium and the microstructure, which can be used to provide, for example, autonomous directional movement, rotation of microgears, microfluidic devices, and novel sensor configurations. In one example, a palladium catalyst is used, and the fluid medium is an aqueous solution of hydrogen peroxide.

A process for the facile two-step synthesis of methanol from methane is disclosed. In accordance with the invention, an appropriate combination of initiator and reaction medium is employed to achieve methane conversion in very high selectivity and yield under near-ambient temperature.

Embodiments in accordance with the present invention encompass photo-imageable compositions that include polymers of acrylate-type monomers and norbornene-type monomers. In some embodiments a catalyst system comprising a cationic or a neutral Pd(II) dimer component having the formula (Allyl)Pd(P(R)) or (L')[(L)Pd(R)(X)], respectively is employed to effect polymerization. In other embodiments a free radical or living free radical catalyst is employed to effect polymerization. At least one of the acrylate-type monomers and norbornene-type monomers of the polymer embodiments of the present invention encompass an acid labile moiety. Some polymer embodiments of the present invention include more than one type of acrylate-type monomer and norbornene-type monomer. Embodiments of the present invention include forming a patterned layer on a substrate and some embodiments include transferring the patterned structure to a material layer first formed on the substrate.

Photo-imageable compositions of norbornene and acrylate copolymers and use thereof

Homopolymers or copolymers of acrylates, homopolymers or copolymers of norbornenes, and copolymers of acrylates with norbornenes, may be prepared by contacting acrylate and/or norbornene monomer reactant under polymerization conditions and in the presence of a solvent with a catalyst system consisting essentially of a Pd(II) dimer component having the formula: &lsqb;(L)Pd(R)(X)&rsqb; , where L is a monodentate phosphorus or nitrogen ligand, X is an anionic group, and R is an alkyl or aryl group.
