  • Patent number: 11349135
    Abstract: A method of preparation and application for a glass ceramic sealing thin strip with high sealing performance, differing from using conventional glass ceramic packaging paste applied to the junction of the cell stack assembly and connecting plates. The glass ceramic sealing thin strip of present invention utilizes tape casting to produce a single layer or multi-layer stacking in accordance with the required thickness of the glass-ceramic sealing thin strip, and cutting the glass ceramic sealing thin strips from molds in accordance with the geometry of cell stacks with equal thickness of the glass ceramic sealing thin strip for SOFC cell stack assembly, aiming to overcome the setbacks of the conventional dispensing method with glass ceramic packaging paste that makes the thickness difficult to control, and to effectively improve sealing performance of the cell stack assembly and the power generation efficiency, and achieve commercial application with mass production.

  • Patent number: 10590178
    Abstract: Chimeric double peptide vaccines are disclosed, useful for inducing active immunity against Candida fungal infections. The chimeric peptide comprises an Fba peptide and an Met6 peptide, covalently linked to one another, with or without an intermediate linker. Fba and Met6 are cell surface components of Candida. When used as a vaccine, the chimeric double peptide vaccine induces stronger protective immunity against fungal infection than does the Fba peptide alone, or the Met6 peptide alone, or a mixture (not covalently linked) of the two peptides.

  • Patent number: 10427143
    Abstract: A new configuration of ZSM-5 is provided whereby the crystals have a higher average silica to alumina ratio at the edges of each crystallite than in the centre as determined from a narrow slit line scan profile obtained from SEM/EDX or TEM/EDX elemental analysis. Such ZSM-5 crystals are obtained by a preparation process using L-tartaric acid. The new configuration ZSM-5 provides significantly reduced xylene losses in ethylbenzene dealkylation, especially when combined with silica as binder, and one or more hydrogenation metals selected from platinum, tin, lead, silver, copper, and nickel.
