Abstract: 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.

Abstract: 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.

Abstract: An exemplary breath analysis system may include a sampling chamber having a molecule collector disposed therein. The molecule collector may be configured such that volatile organic compounds (VOCs) present in a breath sample introduced to the sampling chamber adhere to the molecule collector. A photodiode array configured to excite and/or heat the molecule collector to release at least a portion of the VOCs from the molecule collector to release at least the portion of the VOCs adhered to the molecule collector. An analysis device (e.g., a mass spectrometer or Terahertz (THz) spectrometer) may identify one or more target VOCs from among at least the portion of the VOCs released from the molecule collector and generate an output representative of the identified target VOC(s). The output may include information that quantitates a concentration of the target VOC(s) with respect to a source of the breath sample.

Abstract: An exemplary breath analysis system may include a sampling chamber having a molecule collector disposed therein. The molecule collector may be configured such that volatile organic compounds (VOCs) present in a breath sample introduced to the sampling chamber adhere to the molecule collector. A heating element may introduce heat within the sampling chamber, causing release of at least a portion of the VOCs adhered to the molecule collector. An analysis device (e.g., a mass spectrometer or Terahertz (THz) spectrometer) may identify one or more target VOCs from among at least the portion of the VOCs released from the molecule collector and generate an output representative of the identified one or more target VOCs. The output may include information that quantitates a concentration of the one or more target VOCs with respect to a source of the breath sample.

Abstract: Non-equilibrium conditions and distinctive process-dynamics give laser-powder bed fusion (L-PBF) inherent capability to produce unique microstructural-features. However, alloy-design strategies that not only tackle printability-related challenges but also capitalize on such inherent capability, are imperative. Hence, an alloy-design strategy that integrates concepts of grain-refinement and eutectic-solidification is proposed. Consequently, an Al-3Ni-1Ti-0.8Zr (wt. %) alloy has been designed and processed with L-PBF. The alloy exhibits a wide processing-window, indicating excellent printability, and hierarchical features-enabled heterogeneous grain-structured microstructure; a high synergistic as-built strength-ductility is thus obtained. Notably, wide processing-window allows fine-tuning of as-built microstructure, whereas heterogeneous microstructure potentially allows activation of back-stress strengthening and work-hardening.

Abstract: The present application relates to systems, methods, and computer-readable media for providing generating odors. In aspects, the disclosed methods may include generating, by a chemistry dispersion element, a signal configured to act upon a surface of a chemistry reservoir to disperse an odorous substance retained within the chemistry reservoir. The chemistry reservoir and the chemistry dispersion element may be disposed within a housing. The method also includes generating, by an air pump, a volume of air, and transporting, by an airflow pathway, the volume of air from the air pump to an air outlet. The volume of air passes through at least a portion of the housing as it flows through the airflow pathway from the air pump to the air outlet, and transports at least a portion of the odorous substance dispersed by the chemistry reservoir within the housing to the air outlet.

Abstract: Two-dimensional (2D) material-based metal or alloy catalysts synthesized on carbon materials (e.g., carbon nanotubes) prevent polysulfide shuttling and overcome technical challenges for developing practical lithium-sulfur (Li—S) batteries. Soluble lithium polysulfides (LiPSs) tend to shuttle during battery cycling and corrode a Li anode, leading to eventual performance fading in the Li—S battery. This shuttle effect can be reduced by accelerating the conversion of the dissolved polysulfides to the insoluble LiPSs and back to the sulfur. A 2D material-based alloy or 2D material synthesized on carbon materials can suppress polysulfide shuttling by catalyzing polysulfide reactions. 2D material-based alloys with 2H (semiconducting)-1T (metallic) mixed phase exhibit synergistic effects of accelerated electron transfer and catalytic performance as confirmed by the lower charge-transfer resistance of carbon nanotube (CNT)-S cathode and the high binding energy of LiPSs to the catalyst.

Abstract: The present invention includes an apparatus and method for detecting the location of one or more sources of one or more target molecule, the apparatus comprising: a molecule detector; and a processor connected to the molecule detector and to a global position system, wherein the processor calculates the presence of the one or more target molecules, runs a computer code that determines a dynamic reverse gas stack model for the one or more target molecules, and triangulates the possible position for a source or effluent of the one or more target molecules based on the dynamic reverse gas stack model. The determined reverse gas stack model may have a Gaussian dispersion over one or more sampled locations.
