    • A novel supported mesoporous carbon ultrafiltration membrane and process for producing the same. The membranes comprise a mesoporous carbon layer that exists both within and external to the porous support. A liquid polymer precursor composition comprising both carbonizing and noncarbonizing templating polymers is deposited on the porous metal support. The coated support is then heated in an inert-gas atmosphere to pyrolyze the polymeric precursor and form a mesoporous carbon layer on and within the support. The pore-size of the membranes is dependent on the molecular weight of the noncarbonizing templating polymer precursor. The mesoporous carbon layer is stable and can withstand high temperatures and exposure to organic chemicals. Additionally, the porous metal support provides excellent strength properties. The composite structure of the membrane provides novel structural properties and allows for increased operating pressures allowing for greater membrane flow rates. The invention also relates to the use of the novel ultrafiltration membrane to separate macromolecules from solution. An example is shown separating bovine serum albumin from water. The membrane functions by separating and by selective adsorption. Because of the membrane's porous metal support, it is well suited to industrial applications. The unique properties of the supported mesoporous carbon membrane also allow the membrane to be used in transient pressure or temperature swing separations processes. Such processes were not previously possible with existing mesoporous membranes. The present invention, however, possesses the requisite physical properties to perform such novel ultrafiltration processes.
    • 一种新型支撑介孔碳超滤膜及其制备方法。 膜包括存在于多孔载体内部和外部的介孔碳层。 包含碳化和非碳酸化模板聚合物的液体聚合物前体组合物沉积在多孔金属载体上。 然后将涂覆的载体在惰性气体气氛中加热以热解聚合物前体并在载体上和内部形成介孔碳层。 膜的孔径取决于非碳酸化模板聚合物前体的分子量。 中孔碳层稳定,可承受高温和暴露于有机化学物质。 此外,多孔金属载体提供优异的强度性能。 膜的复合结构提供了新颖的结构特性并且允许增加的操作压力允许更大的膜流速。本发明还涉及新型超滤膜将溶液中的大分子分离的用途。 示出了将牛血清白蛋白与水分离的实例。 膜通过分离和选择性吸附而起作用。 由于膜的多孔金属支撑,它非常适合于工业应用。支撑介孔碳膜的独特性能也允许膜用于瞬态压力或温度摆动分离过程。 这种方法以前不可能用现有的介孔膜。 然而,本发明具有进行这种新型超滤方法所需的物理性能。

    • Sensing compositions, sensing element, sensing systems and sensing devices for the detection and/or quantitation of one or more analytes, Compositions comprising carbon nanotubes in which the carbon nanotubes retain their ability to luminesce and in which that luminescence is rendered selectively sensitive to the presence of an analyte. Compositions comprising individually dispersed carbon nanotubes, which are electronically isolated from other carbon nanotubes, yet which are associated with chemical selective species, such as polymers, particularly biological polymers, for example proteins, which can interact selectively with, or more specifically selectivity bind to, an analyte of interest. Chemically selective species bind, preferably non-covalently, to the carbon nanotube and function to provide for analyte selectivity. Chemically selective species include polymers to which one or more chemically selective groups are covalently attached. Chemically selective polymers include, for example, proteins and polysaccharides.
