    摘要： A method for preparing fluorescent-encoded microspheres coated with metal nanoshells is disclosed herein. By using SPG method, metal nano-material modified with a certain ligand is used as a new surfactant in the emulsification process, and different kinds and different amounts of fluorescent materials are doped into polymer microspheres to prepare fluorescent-encoded microspheres with different fluorescent-encoded signals and uniformly coated metal nanoshells in one step. The prepared fluorescent-encoded microsphere comprises a metal nanoshell, a polymer, and a fluorescent-encoded material. The fluorescent-encoded microsphere has a particle size of 1 μm˜20 μm, CV of less than 10%, which can be used for protein/nucleic acid detection. The preparation method has the advantages of simple process, high surface coating rate, good uniformity and controllable LSPR peaks, which can solve the problems of existing commonly used metal nanoshell coating methods such as low surface coating rate, poor uniformity, complex preparation process and uncontrollable local surface plasmon resonance (LSPR) peaks, etc.

    摘要： A plug valve including a valve body defining an internal cavity, a first passage, and a second passage, a plug defining a third passage and being rotatable within the internal cavity, and an insert extending within the internal cavity between the valve body and the plug. The insert defines an interior surface and an opening aligned with the first passage of the valve body. The insert may also define a sealing surface extending around the opening and standing in relief against the interior surface to sealingly engage the plug. In addition to, or instead of, the sealing surface, the insert may define a projection at least partially defining the interior surface. In addition, a boot may be connected to the valve body and interlocked with the projection to prevent, or at least reduce, rotation of the insert relative to the valve body when the plug rotates within the internal cavity.

    摘要： The present invention addresses the problem of providing a water-in-oil emulsified composition having improved workability in a freezing range. This water-in-oil emulsified composition contains, as constituent fatty acids, 7-29 wt % of lauric acid and 7-19 wt % of palmitic acid, the weight ratio of stearic acid/lauric acid being 0.1-1.6, and has a hardness of 500-1500 gf at −18° C. The water-in-oil emulsified composition according to the present invention, when delivered or stored in a frozen state, can be directly and easily cut into pieces in any shape without requiring an operation such as thawing or temperature adjustment.
