    Abstract: A multi-chamber single-use bioreactor for cell culture expansion has bag assembly and a rigid support structure defining a bag receiving space. The bag assembly disposed in the bag receiving space of the rigid support structure and supported by the rigid support structure. The bag assembly has at least a first flexible bag and a second flexible bag. The first bag defines a first reaction chamber, and the second bag defines a second reaction chamber. The first reaction chamber has a first volume, a first inlet, and a first outlet, and the second reaction chamber has a second volume different from the first volume, a second inlet, and a second outlet. The second inlet of the second bag is fluidically connected to the first outlet of the first bag so liquid in first reaction chamber can be transferred to the second reaction chamber.

    Abstract: Solid polymer electrolyte (SPE) having conductive filler aligned to have directional ionic conductivity. The SPE with aligned conductive filler are used in a structural supercapacitor comprising one or more plies. Each of the plies has a first and second conducting member, each with a plurality of sections with conductive filler oriented normal to the inner surface of the first conducting member. The plies also having a pair of epoxy-SPE layers with aligned conductive filler. The resin layers are between the inner surfaces of the first and second conducting members.

    Abstract: This disclosure relates generally to enabling a user to (1) determine the radial stiffness of the outer surface of a winding or wound roll, and (2) when coupled with a winding/contact model results in a virtual instrument allowing the user to explore the residual stresses due to winding in roll-to-roll manufacturing process machines, and (3) allows the user to predict winding defects and hence roll quality based upon the known residual stresses. Wound roll models require the input of a radial modulus of elasticity which is state dependent on interlayer pressure. The hardware of the disclosure can be used to determine this radial modulus and serves to enable the user to (1) use winding/contact models and (2) with measurements made during or after winding enable the user to estimate the winding residual stresses.

    Abstract: A method is herein presented to statistically combine multiple seismic attributes for generating a map of the spatial density of fractures. According to an embodiment a first step involves interpreting the formation of interest in 3D seismic volume first to create its time structure map. The second step is creating depth structure of the formation of interest from its time structure map. In this application geostatistical methods have been used for depth conversional, although other methods could be used instead. The third step is extraction of a number of attributes, such as phase, frequency and amplitudes, from the time structure map. The next step is to project the fracture density onto the top of the target formation. The final step is to combine these attributes using a statistical method known as Multi-variant non-linear regression to predict fracture density.

    Abstract: According to an embodiment, a method for grafting POSS (polyhedral silsesquioxane) nanomaterial to graphene oxide is described for use in preparation of high performance composite materials. In another embodiment, amine functionalized graphene oxide may be particularly suitable. In this embodiment, POSS molecules grafted to amine functionalized graphene oxide are synthesized by reacting graphene oxide with different POSS molecules. The amine functionalized graphene oxide may be dissolved in a solvent and the reaction may include the presence of a catalyst. The resultant POSS grafted graphene oxide/POSS grafted amine functionalized graphene oxide may be mixed with a resin (epoxy) in a masterbatch. The masterbatch may then be packaged and sold. The masterbatch material may then be introduced into the interlaminar area of graphite/epoxy composites. Biodegradability and interlaminar fracture toughness testing results from the use of epoxy based nanocomposites containing POSS modified graphene oxide polymer are expected to improve.

    Abstract translation: 根据一个实施方案，描述了将POSS（多面体倍半硅氧烷）纳米材料接枝到氧化石墨烯上的方法用于制备高性能复合材料。 在另一个实施方案中，胺官能化石墨烯氧化物可能是特别合适的。 在该实施方案中，通过使氧化石墨烯与不同的POSS分子反应来合成接枝到胺官能化氧化石墨烯上的POSS分子。 胺官能化石墨烯氧化物可以溶解在溶剂中，并且反应可以包括催化剂的存在。 所得到的POSS接枝氧化石墨烯/ POSS接枝胺官能化石墨烯氧化物可与母料中的树脂（环氧树脂）混合。 然后可以将母料包装并出售。 然后将母料材料引入石墨/环氧复合材料的层间区域。 使用含有POSS改性石墨烯氧化物聚合物的环氧基纳米复合材料的生物降解性和层间断裂韧性测试结果有望提高。
