Abstract: An all-ceramic frequency selective surface (ACFSS) material is provided for use in high temperature environments where there is a need for selective transmission of a defined wavelength band of electromagnetic radiation through the material. Unlike traditional frequency selective surfaces that use metals to form a structured or patterned layer that defines the passband, the present ACFSS material uses electrically conductive ceramic materials to form the patterned layer, giving the material a much greater heat stability than metal-containing frequency selective surface materials.

Abstract: An interconnected open-pore 2.5D Cu/CuO foam-based photothermal evaporator capable of achieving a high evaporation rate of 4.1 kg m?2 h?1 under one sun illumination by exposing one end of the planar structure to air is disclosed. The micro-sized open-pore structure of Cu/CuO foam allows it to trap incident sunlight, and the densely distributed blade-like CuO nanostructures effectively scatter sunlight inside pores simultaneously. The inherent hydrophilicity of CuO and capillarity forces from the porous structure of Cu foam continuously supply sufficient water. Moreover, the doubled working sides of Cu/CuO foam enlarge the exposure area enabling efficient vapor diffusion. The feasible fabrication process and the combined structural features of Cu/CuO foam offer new insight into the future development of solar-driven evaporators in large-scale applications with practical durability.

Abstract: A framework for joint computation, caching, and request forwarding in data-centric computing-based networks comprises a virtual control plane, which operates on request counters for computations and data, and an actual plane, which handles computation requests, data requests, data objects and computation results in the physical network. A throughput optimal policy, implemented in the virtual plane, provides a basis for adaptive and distributed computation, caching, and request forwarding in the actual plane. The framework provides superior performance in terms of request satisfaction delay as compared with several baseline policies over multiple network topologies.

In various embodiments, the first and second microorganisms are incubated with a candidate compound or a producer thereof. The different labels permit isolation of microorganisms exhibiting one of the labels but not the other, indicating the desired activity, and the compound responsible for this differential response is isolated.
