    摘要: The present disclosure provides a system, method, and apparatus for detecting chemical effluents in an environment using Teslin substrates. To illustrate, a system includes one or more Teslin substrates which can capture molecules present in an ambient environment. The system includes a housing with the one or more Teslin substrates disposed within the housing. The system further includes means for selectively exposing different portions of the one or more Teslin substrates to the ambient environment, in which the molecules present in the ambient environment are captured by the different portions of the one or more Teslin substrates as the different portions of the one or more Teslin substrates are exposed. The system can include that the means for selectively exposing different portions of the one or more Teslin substrates is an aperture in the housing.

    摘要: A monolithic dielectric coating composed of microscale periodic high-contrast gratings on multilayers of high and low refractive index optical materials is described, which is deposited on metal thin-films of flexible polymer insulation sheeting. The emittance can be minimized to any blackbody temperature, using parameter optimization of high-contrast grating phase-shift mode conditions. The high-low refractive index infrared-transparent multilayer is based on Fabry-Pérot cavity, but with non-quarter-wave thicknesses to achieve multilayer insulation conductance below that of metal films. This ultralow emittance coating is most relevant to thermal management of refrigeration and electronic components.
