  • Patent number: 9039949
    Abstract: A method is for molding a gas hydrate pellet for improving convenience of handling of a natural gas hydrate during transportation and storage, and thereby improving the practical use of the natural gas hydrate. Gas hydrate slurry is fed in a compression chamber, and pressure and compression are applied to the gas hydrate slurry by advancing a compression plunger. At that time, a stroking speed of the compression plunger is set minimum, preferably less than a value expressed by a stroke length of the compression plunger at compression×10?2 (m/min. By advancing the compression plunger at low speed, binding between particles of the gas hydrate is tightened, thereby the gas hydrate pellet with increased shearing strength can be molded.

    Abstract: FRET measurement uses a FRET probe that includes a probe element X containing a donor fluorescent substance and a probe element Y containing an acceptor fluorescent substance and enables FRET to occur when the probe element X and the probe element Y approach to each other or bind together. The modulation frequency of laser light with which the FRET probe is irradiated is adjusted to an optimum modulation frequency that maximizes a difference between the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET occurs and the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET does not occur.
