  • Patent number: 9393312
    Abstract: The present invention relates to a novel amphiphilic block copolymer and the preparation method thereof, as well as a micellar drug-loaded system formed by said copolymer and an anti-tumor drug. Said amphiphilic block copolymer comprises a hydrophilic segment and a hydrophobic segment, and the end group of said hydrophobic segment is end-capped with a hydrophobic group. Methoxypolyethylene glycol (or polyethylene glycol)-polyester block copolymer which has recognized safety is used as a fundamental material of the amphiphilic block copolymer of the present invention, and the terminal hydroxyl group of the polyester segment is modified with a hydrophobic group, whereby the compatibility between the drug molecule and the hydrophobic segments of the block copolymer is improved, and the interaction therebetween is enhanced. Moreover, a larger space for accommodating the drug molecules is provided.

  • Patent number: 8408004
    Abstract: A combustor for a gas turbine engine and related method is provided in which a plurality of combustor cans are selectively adapted with corresponding resonators. The resonators may, for example, be attached to every can in the consecutive arrangement of combustor cans, every other can, every third can or the like, and may be tuned to the same or first, second, third, etc. frequencies of operation. Such selective tuning is configured to suppress one or more of out-of-phase and in-phase dynamic interaction of streams discharged from adjacent combustor cans by changing the frequencies of pressure oscillation instabilities across the arrangement of consecutive cans.
