  • Publication number: 20240140862
    Abstract: The present application discloses a glass fiber sizing composition. The glass fiber sizing composition comprises effective components and water, and has a solid content of 4.0% to 6.0%; and the effective components comprise a silane coupling agent, a film former, a lubricant, a surfactant, a leveling agent, an interfacial reinforcing agent, a wetting agent, a defoaming agent, and a pH regulator. A glass fiber produced by the sizing composition has desirable strand integrity properties, softness and high dispersibility after a certain tension; the glass fiber also has high permeation velocity and complete permeation effect in the epoxy resin. The glass fiber shows excellent interfacial compatibility with the resin, and is suitable for weaving technology, especially for producing a heavy wind blade fabric. A composite formed by vacuum infusion of the fabric and the epoxy resin has desirable static mechanics and fatigue properties.

  • Patent number: 11312645
    Abstract: The present invention discloses a high-concentration organic wastewater treatment reactor. A lower water distribution system, an upper water distribution system, a lower three-phase separator and an upper inclined plate separator are provided from bottom to top in a reactor body of the high-concentration organic wastewater treatment reactor. A gas-liquid separator is disposed on the top of the reactor body. The lower water distribution system and the upper water distribution system are connected to an influent pipe. A lower biogas ascending pipe connected to the gas-liquid separator is disposed on the top of the lower three-phase separator. An upper biogas ascending pipe and an effluent pipe are disposed above the upper inclined plate separator. An outlet end of the upper biogas ascending pipe is connected to the gas-liquid separator. A downcomer is disposed on the bottom of the gas-liquid separator. An air pipe is disposed on the top of the gas-liquid separator.

  • Publication number: 20100297622
    Abstract: The present invention embraces a method for high-throughput gene profiling with high specificity and sensitivity. With this system, >1000 mRNA species can be co-amplified using gene-specific primers from a single cell. The primers are designed to amplify sequences of desirable length, which are in different exons. The exons can be either adjacent and separated by a large intron or include more than two exons. The amplified sequences are then analyzed by microarray with probes hybridizing to neighboring exons.

  • Publication number: 20100248988
    Abstract: There exists a need in the art for high throughput screening assays that can identify compounds that specifically modulate the activity of fast-acting ion channels, such as TRPM5. Current methods suffer from a lack of sensitivity, low throughput, and are labor intensive. The claimed methods provide fluorescent assays with an optical readout that gives rapid readout of the results, has a high signal to noise background ratio, are easy to use, can be modified for automation and miniaturization, and provide verification that a compound specifically modulates TRPM5.

  • Publication number: 20100248987
    Abstract: The invention relates an assay useful for screening and identifying compounds as modulators of lower alkyl phenol activation of TRPA1. Thymol, a lower alkyl phenol anti-infective and the active ingredient in, e.g., mouthwashes, is stringent and has an objectionable burning taste sensation. Thymol activates the transient receptor potential like ion channel TRPA1. The assay described and claimed herein involves measurement of activation of TRPA1 and enables the screening of compounds that inhibit lower alkyl phenol, or thymol activation of TRPA1. Inhibitors of thymol activation of TRPA1 can be used to prevent the objectionable taste of thymol in medical uses where taste limits acceptance.
