  • Patent number: 12606878
    Abstract: An Al—Si coated press hardening component, wherein the Al—Si coating comprises a low-Al content ferrite layer with an Al content of less than 5 wt % and a thickness of greater than 5 ?m, and having a maximum bending angle of the Al—Si coated press hardening component is greater than 65°. The thickness of the tough low-Al content ferrite layer in the Al—Si coating after hot stamping, reaching 5-100 ?m, by improving the hot stamping process, so that the formation or propagation of cracks on the surface or the coating is effectively prevented, and the bendability of the pre-coated steel after hot stamping is improved. At the same time, the hot stamping process of the present invention can take into account or optimize the microstructure of the steel substrate to further improve the bendability and tensile property of the whole material.

  • Patent number: 6849414
    Abstract: Assay devices, kits, and methods for detection of one or more analytes in a sample are provided. The assay device features the controlled release of reagents and hence is particularly suitable for binding assays such as immunoassays. The assay device achieves greater sensitivity than conventional rapid test assays, leading to stronger and/or more stable visual signals than those produced by conventional devices, easier interpretation of results, and reduced occurrence of indeterminate results. The device can be used for detecting analyte in a variety of biological samples without the need for conventional sample filtration techniques, and thus is suitable for use by untrained personnel without specialized equipment. In addition, the device can be used to simultaneously analyze a number of analytes using a single sample.

  • Patent number: 5824506
    Abstract: Peptide antigens derived from the dengue virus type-2 glycoprotein NS1 are provided. The peptide antigens are specifically immunoreactive with sera from individuals infected with the dengue virus. The antigens are useful as diagnostic tools in determining whether an individual has been or is infected with dengue virus, and for discriminating between infection with dengue virus and infection with related flaviviruses. The antigens are also useful in vaccine compositions for immunizing individuals against infection with the dengue virus.
