摘要： Tungsten carbide catalysts are used in preparation of ethylene glycol by hydrogenating degradation of cellulose. The catalyst includes tungsten carbide as main catalytic active component, added with small amount of one or more transition metals such as nickel, cobalt, iron, ruthenium, rhodium, palladium, osmium, iridium, platinum, and copper as the second metal, supported on one or more porous complex supports such as active carbon, alumina, silica, titanium dioxide, silicon carbide, zirconium oxide, for conversion of cellulose to ethylene glycol. The catalyst realizes high efficiency, high selectivity, and high yield in the conversion of cellulose to ethylene glycol at the temperature of 120-300° C., hydrogen pressure of 1-10 MPa, and hydrothermal conditions. Compared to the existing industrial synthetic method of ethylene glycol using ethylene as feedstock, the invention has the advantages of using renewable raw material resources, environment friendly process, and excellent atom economy.

摘要： A method of manipulating a focused light beam includes focusing a beam of excitation light with a lens to a focal spot within a sample, where a cross-section of the beam includes individual beamlets. Directions and/or relative phases of the individual beamlets of the excitation beam at a rear pupil of the lens are individually varied with a wavefront modulating element, and emission light emitted from the focal spot is detected while the directions or relative phases of individual beamlets are varied. The directions of individual beamlets are controlled to either maximize or minimize the emission light from the focal spot, and the relative phases of individual beamlets are controlled to increase the emission light from the focal spot.
