  • Publication number: 20250207865
    Abstract: A vapor chamber includes a vapor chamber body, multiple dendritic wick structures and a working fluid. The vapor chamber body includes a hollow shell and a capillary wick layer covered on an inner wall of the hollow shell. Each dendritic wick structure has a capillary base and multiple capillary braches. A side of the capillary base is sintered and connected to the capillary wick layer and another side has a convex curved portion. The multiple capillary branches are extended from and formed as one piece with the convex curved portion. The working fluid is filled in the hollow shell. Thereby, the multiple capillary branches and the convex curved portion can increase cooling surface area of the dendritic wick structure to make the vapor chamber and the dendritic wick structure have great cooling efficiency.

  • Patent number: 12291716
    Abstract: The invention discloses a plant thermo-sensitive male sterile gene mutant tms15 and uses thereof. The nucleotide sequence of the plant thermo-sensitive male sterile gene mutant tms15 is SEQ ID No. 1. The inventor screened the thermo sensitive genic male sterile mutant tms15 by EMS mutagenesis of Zhonghua 11, which showed a male sterile phenotype under high temperature conditions (>28° C.) and restored fertility under low temperature conditions (22˜24° C.). The cytological results shows that the sporogenous cells in tms15 plants proliferated excessively and the tapetum cells are also vacuolized abnormally under high temperature. The normal proliferation of sporogenous cells and the normal development of tapetal cells are restored to some extent after low temperature treatment.
