Abstract: The present invention discloses a surface treatment method for use in enhancing oxidation resistance of copper powder. According to the surface treatment method, a copper powder and a first modifier are sequentially added into a liquid medium. Next, after evenly stirring the liquid medium, a second modifier is added into the liquid medium so as to ontain a first liquid mixture. Subsequently, after evenly stirring the first liquid mixture, it is utilized suction filtration apparatus to filter a surface-modificated copper powder out of the first liquid mixture. After completing the surface treatment method, the surface-modificated copper powder shows outstanding oxidation resistance.

Title: Method for testing target nucleic acid in sample
Inventor: Pan weiye
Filed: 2023-05-12
Abstract: Provided is a method for detecting a target nucleic acid in a sample, comprising the following steps: reacting the sample with a mixed reaction system consisting of a sgRNA-Cas system and a recombinase-aid isothermal amplification system; and detecting a detectable signal generated by the reaction after the reaction is completed. The sgRNA-Cas system comprises a Cas12b protein and a sgRNA targeting the target nucleic acid; the recombinase-aid isothermal amplification system comprises a primer, a single-stranded DNA reporter molecule that generates the detectable signal after being cleaved. When a reagent user operates, a sample adding and mixing operation of stopping the reaction midway to add reaction component of the second step is leaved out, so that uniformity and coherence of the operation are better, facilitating the improvement of reaction precision. The operation of opening a reaction tube after the amplification reaction of recombinant polymerase is omitted. In addition, when these two reactions are mixed, the cis-cleavage activity of Cas protease will digest the amplification product, so that it will not be released into the environment to become a pollution source, which is especially important for high-throughput and high sensitivity detection; and the reaction sensitivity is improved.

Title: Floating multi-shaped oceanographic station
Inventor: THANOS IOANNIS
IPC: B63B22/00
Filed: 2003-10-17
Abstract: he invention relates to a floating oceanographic data-measuring station being presented in a multi-shaped design, what means that its final shape is created in relationship to the measurements and equipment of organs required by the final user. So far, the floating stations of oceanographic measurements have been designed to receive a precise number of sensing elements, while the form of their hull is defined by the kind of measurements to be done. Later equipment with sensing elements exceeding in number the sensing elements provided by the construction design proved to be almost impossible. Considering its modular construction, the precise oceanographic station is designed to operate in, at least, four independent geometrical forms. Consequently, it can be equipped with different oceanographic organs, while gradual extension of the station is enabled. Alternately, it can operate as a floating sphere for waves measurements, as a floating sphere incorporated to the central frame equipped with a few organs, as a medium-sized platform of measurements with sufficient meteorological and environmental organs, and as an extended environmental platform equipped with additional voluminous undersea organs adapted to the anchoring section.
