Abstract:
Size-controlled immobilization of metal nano-clusters onto particles or nanoparticles is achieved using a polyol process. Polyol processing makes it possible to use thiol groups as a chemical protocol to functionalize the surface of particles, such as silica and polystyrene nanoparticles. Metal nano-clusters, such as silver, gold, platinum and palladium, nucleate and grow on the surface of the particles. The metal nano-clusters may be synthesized in a one-pot process from metal salts, nitrates, nitrites, sulfates, sulfites and the like. Any source of metal ions compatible with the polyol suspension and selected particles may be used. The size of immobilized metal nano-clusters may be controlled by additions of a poly(vinylpyrrolidone) or other polymer capable of regulating the metal ion reduction and nucleation process and by controlling concentration of metal ions, the nucleation and/or growth temperatures, and processing time.
Abstract:
The present disclosure discloses a catalyst for directly producing a lactide which is a cyclic ester used as a monomer for polylactides, and a method for directly producing a lactide using the catalyst, the method including the transesterification reaction between two molecules of an ester of lactic acid or a mixture containing the ester of lactic acid with a small amount of lactic acid and oligomer of lactic acid under an inert environment in the presence of a titanium-based catalyst or a catalyst mixture containing the titanium-based catalyst so as to produce lactide while simultaneously removing an alcohol (ROH) generated as a by-product. As compared to a conventional commercialized process, since the method for producing a lactide in accordance with the present disclosure is a novel process capable of directly producing the lactide from the ester of lactic acid, energy consumption is low and the lactide can be produced through a simple process showing a high yield while maintaining optical property (D-form or L-form optical isomer).
Abstract:
Apparatus for stabilizing carrier-envelope phase (CEP) of laser pulse generated by mode locked pulsed laser based on direct locking method includes laser oscillator, interferometer, detector and double feedback circuit. The laser oscillator includes the mode locked pulsed laser generating the laser pulse. The interferometer generates laser pulses having first and second frequency components from the laser pulse generated by the mode locked pulsed laser to generate first and second interference signals that substantially correspond to each other in time domain and space domain. The detector receives the first and second interference signals to output third and fourth interference signals by inverting phase of the second interference signal. The double feedback circuit controls the laser oscillator so that the CEP of the laser pulse generated by the mode locked pulsed laser has substantially constant value with respect to time using CEP signal obtained from the third and fourth interference signals.
