    摘要: The present invention provides a process for producing a stamp for hot embossing (HE). The stamp can be constructed from any photo-resist epoxy that is stable at temperatures equal to the glass transition temperature (T g ) of the material to be stamped. The stamp can be used repeatedly without significant distortion of features. The stamp benefits from low relative cost, high fidelity of features in all three-dimensions and fast construction. The process for producing a stamp for hot embossing from a resist, comprising the steps of producing a seed layer L1 from a selected photoresist polymer material, soft baking the seed layer L1, exposing said seed layer L1 to initiate cross-linking and then post-exposure bake L1 to fully cross-link it, coating the cross-linked seed layer L1 with a second photoresist polymer layer L2; soft baking the second photoresist polymer layer L2; applying a mask to the top surface of the soft baked layer L2 and illuminating the unmasked portions of the soft baked layer L2 with UV radiation through the mask, wherein the exposed areas form the pattern of the embossing features, washing away un-exposed regions of the photoresist with a developer to leave behind a relief pattern formed in the second photoresist polymer layer L2, which relief pattern corresponds to a pattern in the mask.

    摘要: A method for extracting proteins from heterogeneous fluids by precipitation using microfluidics. The method uses a digital microfluidic device having an array of discrete actuating electrodes formed on a substrate surface, a hydrophobic working surface coating the substrate surface and array of discrete actuating electrodes, an actuating electrode controller for exciting or de-exciting discrete actuating electrodes for translating liquid droplets over the hydrophobic working surface. Droplets containing protein are dispensed onto positions on the hydrophobic working surface, and droplets containing a protein precipitant are deposited as well. All the drops are translated to one or more corresponding designated protein extraction positions on the hydrophobic working surface where they mix. The mixed drops are incubated at the extraction positions to precipitate the protein contained in the droplets to separate the precipitated protein from a drop of supernatant above the precipitate. Supernatant drops are removed and the precipitants are washed and then precipitants are dried. The method uses an automated protocol for precipitation of proteins onto surfaces, rinsing the precipitates to remove impurities, and resolubilization in buffer for further analysis. The method is compatible with proteins representing a range of different physicochemical properties, as well as with complex mixtures such as fetal bovine serum and cell lysate.

    摘要: The present invention provides a template-directed self-assembly strategy to integrate the class of materials called dendrimers with periodic mesoporous and macroporous silica materials to create two totally new classes of organic/inorganic nanocomposite materials, which we call periodic mesoporous dendrisilicas (PMeDs) and periodic macroporous dendrisilicas (PMaDs). The unusual combination of inorganic silica and organic dendrimer chemical structures with these scales of porosity and surfaces suggests a myriad of uses for PMeDs and PMaDs, such as the controlled release and uptake of chemicals, chiral separations and catalysis, electronic printing and microelectronic packaging, biomaterial platforms, chromatography stationary phase, and photonic crystal applications. These applications target the synergistic relationship between the dendrimer and the meso- or macroporous structure within a single hierarchical nanostructured organic/inorganic hybrid material.

    摘要: Asymmetric SRAM cell designs exploiting data storage patterns found in ordinary software programs wherein most of the bits stored are zeroes for data and instruction streams. The asymmetric SRAM cell designs offer lower leakage power with little impact on latency. In asymmetric SRAM cells, selected transistors are "weakened" to reduce leakage current when the cell is storing a zero. Transistor weakening may be achieved by using higher voltage threshold transistors, by varying transistor geometries, or other means. In addition, a novel sense amplifier design is provided that leverages the asymmetric nature of the asymmetric SRAM cells to offer cell read times that are comparable with conventional symmetric SRAM cells. Lastly, cache memory designs are provided that are based on asymmetric SRAM cells offering leakage power reduction while maintaining high performance, comparable noise margins, and stability with respect to conventional cache memories.
