摘要： The present invention describes a composition and a method for producing mesoporous silica materials with a chiral organization. In the method, a polymerizable inorganic monomer is reacted in the presence of nanocrystalline cellulose (NCC) to give a material of inorganic solid with cellulose nanocrystallites embedded in a chiral nematic organization. The NCC can be removed to give a stable porous structure that retains the chiral organization of the NCC template. The new materials may be obtained as iridescent free-standing films with high surface area. Through control of the reaction conditions, the color of the films can be varied across the entire visible spectrum. These are the first materials to combine mesoporosity with long-range chiral ordering that leads to photonic properties. Examples of possible applications of the materials are: lightweight reinforcement materials, low k dielectric materials, tunable reflective filters, adsorbents, stationary phases for chromatography of chiral or achiral substances, supports for catalysts (e.g., for asymmetric synthetic transformations), and as a template to generate other new porous materials (e.g., porous carbon or porous metals), preferably with chiral nematic structures.
摘要翻译：本发明描述了一种具有手性组织的制备介孔二氧化硅材料的组合物和方法。在该方法中，可聚合的无机单体在纳米晶体纤维素（NCC）的存在下反应，得到嵌入手性向列组织中的纤维素纳米晶的无机固体材料。可以除去NCC以产生保持NCC模板的手性组织的稳定的多孔结构。新材料可以获得具有高表面积的彩虹色自立膜。通过控制反应条件，可以在整个可见光谱范围内改变膜的颜色。这些是将介孔度与长距离手性排序结合起来产生光子性质的第一种材料。材料的可能应用的例子有：轻质增强材料，低k电介质材料，可调谐反射滤光片，吸附剂，手性或非手性物质层析固定相，催化剂载体（如用于不对称合成转化），以及模板以产生其它新的多孔材料（例如，多孔碳或多孔金属），优选具有手性向列结构。

摘要： A method for creating a highly breathable and waterproof fabric based on hydrophobic plastic (such as PVDF) as a membrane layer. This new fabric allows higher water vapor throughput and better water resistance than other PVDF and ePTFE membranes. This is achieved through control of pore size, thus creating a spongy porous structure, pre-stressing to make the membrane and subsequent laminated fabric soft, and a microscopically folded structure which increases the surface area for the porous media, thus gaining higher throughput, waterproofness and comfort. In addition, the invention provides a method of controlling pore size distribution, increased porosity and pre-stress relief during the gelation proces.

摘要： A thin-film-composite hollow-fiber membrane includes a phase-inversion layer, which is in the form of a hollow fiber, and an active layer coated on the phase-inversion layer. The active layer selectively allows passage of water molecules but rejects at least some dissolved ions. The thin-film-composite hollow-fiber membrane can have an internal burst pressure of at least 4 MPa. In a method for forming the membrane, the polymer concentration in the spinning dope from which the hollow-fiber substrate is formed can have a polymer concentration no greater than 5% below the critical concentration.

摘要： The present disclosure relates to semipermeable membranes which are suitable for blood purification, e.g. by hemodialysis, which have an increased ability to remove larger molecules while at the same time effectively retaining albumin. The membranes are characterized by a molecular retention onset (MWRO) of between 9.0 kD and 14.5 kD and a molecular weight cut-off (MWCO) of between 55 kD and 130 kD as determined by dextran sieving curves and can be prepared by industrially feasible processes excluding a treatment with salt before drying. The invention therefore also relates to a process for the production of the membranes and to their use in medical applications.
