    摘要： A laser system (23) using ultrashort laser pulses is provided. In another aspect of the present invention, the system includes a laser (23), pulse shaper (121) and detection device (35). A further aspect of the present invention employs a femtosecond laser (223) and a spectrometer (503). Still another aspect of the present invention uses a laser beam pulse (23), a pulse shaper (121) and a SHG crystal (507). In yet another aspect of the present invention, a multiphoton intrapulse interference phase scan system and method characterize the spectral phase of femtosecond laser pulses. Fiber optic (451) communication systems, photodynamic therapy and pulse characterization tests use the laser system with additional aspects of the present invention.

    摘要： A process for producing protected 3-amino-1,2-dihydroxypropane acetal, particularly in chiral forms, for use as an intermediate in the preparation of various 3-carbon compounds which are chiral. In particular, the present invention relates to the process for preparation of 3-amino-1,2-dihydroxypropane isopropylidene acetal. The protected 3-amino-1,2-dihydroxypropane acetal is a key intermediate to the preparation of chiral 3-carbon compounds which in turn are intermediates to various pharmaceuticals.

    摘要： A method for the preparation of new quasi-crystalline, porous inorganic oxide materials possessing uniform framework-confined mesopores in the range 2.0-10.0 nm and large elementary particle size of more than 500.0 nm. The method uses an interaction between various non-ionic polyethylene oxide based surfactants (N DEG ) and neutral inorganic oxide precursors (I DEG ) at ambient reaction temperatures. The materials formed exhibit semi-ordered arrays of well defined pores owing to the specific mechanism of self-assembly, large pore wall thicknesses of at least 2.0 nm producing highly stable materials and large particle sizes incorporating large numbers of pores. This (N DEG I DEG ) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.
