    摘要: The present invention relates to a process for producing high-quality crystals of protein or organic substances easily and efficiently. A solution of protein or an organic substance is prepared and then is cooled slowly to be supersaturated to a low degree. This supersaturated solution is irradiated with a femtosecond laser 10. A local explosion phenomenon occurs at the focal point of the laser and thereby a crystalline nucleus is generated. A high-quality crystal is obtained when a crystal is grown on the crystalline nucleus over a long period of time. The femtosecond laser to be used herein can be a titanium:sapphire laser having a wavelength of 800 nm, a duration of 120 fs, a frequency of 1 kHz, and an output of 400 mW.

    摘要: The present invention provides a fullerene suspension and a method for producing a fullerene suspension having high dispersion stability without any chemical compound. Also, the fullerene suspension and its producing method makes it possible to be applied in various fields including the field of medical and pharmaceutical science and the field of foods and environment, in which the fullerene suspension obtained by the prior methods had not been applied. The fullerene is ground to form nanoparticles by irradiating a fullerene in a poor solvent with a laser. The pulse laser having a width of several-ten femtoseconds to several-hundred nanoseconds is appropriately applied.

    摘要: To derive spectrum information on chemical intermediates in photochemical reactions during transitional periods, a transient grating spectroscopy uses white light as the probe light in the pico-second region and monochromatic light in the microsecond region. According to the procedure, it is possible to analyze the photochemical reaction of thin films and interface layers as a function of time at a high precision.
