Abstract: A high-flux composite nanofiltration (NF) membrane with an electrical double layer (EDL) and a preparation method thereof are provided. The high-flux composite NF membrane includes: a charged support membrane and a charged separation layer, where a charge carried by the support membrane or the separation layer is a positive charge, a negative charge, or an amphiprotic charge. The high-flux composite NF membrane with an EDL solves the technical problem that the composite NF membrane in the prior art has an unsatisfactory retention rate and a limited application range due to a small charge quantity.

Abstract: A low-pressure high-flux hollow fiber nanofiltration (NF) membrane, and a preparation method and use thereof are provided. The low-pressure high-flux hollow fiber NF membrane includes a base membrane and a negatively-charged separation layer formed on a surface of the base membrane, where a material of the separation layer is a crosslinking product of a negatively-charged sulfonated polymer. The low-pressure high-flux hollow fiber NF membrane of the present disclosure solves the technical problem that the hollow fiber NF membranes in the prior art are difficult to have both high performance and low energy consumption.

Abstract: A housing for a scroll compressor and a scroll compressor are provided. The housing includes: a cannular central part; a center hole disposed at the cannular central part; a plurality of arms substantially extending radially from the cannular central part, the plurality of arms being used to be connected with a fixed scroll of the scroll compressor; and a thrust bearing surface disposed on a first side of the cannular central part in an axial direction, the thrust bearing surface being used to support an orbiting scroll. The orbiting scroll is supported with low friction, the motor supporting shell tube and the fixed scroll are connected with better alignment, and materials and machining costs are saved. In addition, the housing can provide better support for a scroll set, thereby achieving better performance.

Abstract: The present invention provides a novel gene, IAP, which encodes a soluble protein that is involved in the initiation of an inflammatory cytokine response and which may interact with the anti-inflammatory IL-13. The protein of the present invention may be involved as a central mediator in ischemia, reperfusion, asthma and other inflammation-induced pathological conditions. The invention relates to methods for using isolated polypeptides and polynucleotides, for detecting the early onset of chronic asthma, psoriasis, stroke, ischemia, reperfusion, leishmaniasis, helminthiasis, hypoxia, or other causes of renal, liver or heart failure in a mammal, where increased cytokine activity is known to play a role.
