摘要： A cost-effective broadband tunable Fabry-Perot interferometer uses entropic, rather than enthalpic, materials to provide the compliant support for the interferometer's movable mirror. Entropic materials exhibit an entropic plateau region over a wide frequency range with a Young's modulus much lower than enthalpic materials, linear elastic behavior over a wide deformation range, and, in certain geometries, energy and stress behavior that tend to stabilize the movable mirror during deformation. The compliant support can be configured in a variety of geometries including compression, tension, sheer and diaphragm and of a variety of materials including elastomers, aerogels or other long chained polymers.

摘要： A superlens that includes, in one example embodiment, a positive-index material adjacent to a negative-index material, wherein the negative-index material includes aluminum. In a more specific embodiment, the positive-index material includes a dielectric layer, such as Poly(Methyl MethAcrylate) (PMMA), which is less than 50 nanometers thick. The negative-index material includes a smoothed aluminum layer less than 50 nanometers thick. The aluminum layer is disposed on the dielectric layer or vice versa, forming a superlens comprising the aluminum layer and the dielectric layer. In another embodiment, the superlens further includes plural aluminum layers separated by one or more layers of positive-index material. A mask is adjacent to the positive-index material. The mask may include one or more features that extend into a transparent substrate. The mask is positioned so that the positive-index material separates the mask from the smoothed aluminum layer. In an illustrative embodiment, the superlens is adapted for use with thermal lithography using nanoparticles.
摘要翻译：在一个示例性实施例中，包括与负折射率材料相邻的正折射率材料的超薄体，其中负折射率材料包括铝。在更具体的实施方案中，正指数材料包括介电层，例如小于50纳米厚的聚甲基丙烯酸甲酯（PMMA）。负折射率材料包括小于50纳米厚的平滑的铝层。铝层设置在电介质层上，反之亦然，形成包含铝层和电介质层的超薄层。在另一个实施例中，超薄膜还包括由一层或多层正折射率材料隔开的多个铝层。掩模与正指数材料相邻。掩模可以包括延伸到透明基底中的一个或多个特征。将掩模定位成使得正折射材料将掩模与平滑的铝层分离。在说明性实施例中，超薄适用于使用纳米颗粒的热平版印刷。

摘要： A apparatus for studying the effects of steady and transient flow fields on a sample. The apparatus includes: (a) a flow chamber through which a sample can flow comprising a port arranged to accommodate an analytical probe for measuring the properties of the sample as it moves through the flow chamber; (b) a temperature-controlled thermal reservoir that houses the flow chamber; (c) a sample reservoir comprising a chamber in communication with the flow chamber; (d) a displacement piston arranged to apply pressure, upon activation, to a sample residing in the chamber of the sample reservoir to force the sample into the flow chamber; and (e) an actuator arranged to apply pressure to the displacement piston to activate the displacement piston.
