摘要： A method for removing ethylene from the atmosphere surrounding an agricultural product that is sensitive to ethylene, which promotes climacteric ripening and senescence, is disclosed. The method uses a membrane for selective ethylene permeation and removal from a container that is used to store, transport, and preserve the agricultural product.

摘要： Biotin-containing monomers, polymeric materials formed from the biotin-containing monomers, articles containing the polymeric materials, methods of making the articles, and methods of using the articles are provided. The articles can be used, for example, for affinity capture of biotin-binding proteins, including biotin-binding fusion proteins (i.e., a biotin-binding protein fused to another biomaterial). Articles that contain captured biotin-binding proteins can be further used for affinity capture of various biotin-containing biomaterials such as biotinylated proteins. The articles can also be used, for example, for affinity capture of biotin-binding fusion proteins where the fusion protein includes, for example, an enzyme or antibody.

摘要： Methods of making blended, isoporous, asymmetric (graded) films (e.g. ultrafiltration membranes) comprising two or more chemically distinct block copolymers and blended, isoporous, asymmetric (graded) films (e.g. ultrafiltration membranes) comprising two or more chemically distinct block copolymers. The generation of blended membranes by mixing two chemically distinct block copolymers in the casting solution demonstrates a pathway to advanced asymmetric block copolymer derived films, which can be used as ultrafiltration membranes, in which different pore surface chemistries and associated functionalities can be integrated into a single membrane via standard membrane fabrication, i.e. without requiring laborious post-fabrication modification steps. The block copolymers may be diblock, triblock and/or multiblock mixes and some block copolymers in the mix may be functionally modified. Triblock copolymers comprising a reactive group (e.g., sulfhydryl group) terminated block and films comprising the triblock copolymers.

摘要： The invention, belonging to the field of membrane technology, presents a method for the high-throughput preparation of carbon nanotube hollow fiber membranes. This method contains three major steps. Firstly, the pristine carbon nanotubes (CNTs) are added into a mixture of concentrated nitric acid and sulfuric acid, which is then heated at 40˜80° C. for 0.5˜6 hours. Secondly, the surface-functionalized CNTs and polyvinyl butyral (PVB) are dispersed and dissolved, respectively, in organic solvents at a mass ratio of 1:0.2˜1:4˜8 to form homogeneous spinning solution, which is squeezed into water as shell liquid with water as core liquid at a flow rate ratios of 0.5˜5:1 through a spinneret to form CNT/PVB hollow fibers. Finally, the dry fibers are calcinated at 600˜1000 ° C. for 1˜4 hours in absence of oxygen to produce free-standing CNT hollow fiber membranes. The method involved in this invention is simple and highly efficient without needing any templates, expensive apparatuses and chemicals. Additionally, the obtained electrically conductive CNT hollow fiber membranes feature a high porosity, high water flux and strong acid/alkali resistance.
