Abstract: A mid-infrared gas sensor based on a tapered sub-wavelength grating slot waveguide comprises a lower cladding, a first tapered grating array and a second tapered grating array. The first tapered grating array and the second tapered grating array are disposed on an upper surface of the lower cladding. The first tapered grating array is located in front of the second tapered grating array. The first tapered grating array is formed by 5566 identical first core waveguides that are regularly distributed at intervals from left to right. The second tapered grating array is formed by 5566 identical second core waveguides that are regularly distributed at intervals from left to right. The first core waveguides and the second core waveguides are tapered waveguides. Upper sides and lower sides of the first core waveguides and the second core waveguides are isosceles trapezoids.

Abstract: The present invention relates to a urethane group-containing polyisocyanate prepared by reacting a system containing organic polyhydroxy compounds and excess toluene diisocyanate and, a process for preparing the same, a product containing the polyisocyanate, and the use thereof as a polyisocyanate component in a polyurethane paint and a polyurethane adhesive. The polyisocyanate has the following characteristics: a. the ratio of the integral area of the component peaks having a. weight-average molecular weight of 800±50 to the integral area of the shoulder peaks having a weight-average molecular weight of 950±50 is 2-14; and b. the viscosity is not higher than 2500 mPa·s. The polyisocyanate of the present invention has a good storage stability.

Abstract: A dynamic switching thermoelectric thermal management system and method is disclosed. The thermal management system includes a heat dissipation device, a thermoelectric module, an ambient temperature sensor, a heat source temperature sensor, an energy storage device and a controller. One side of the thermoelectric module is thermally coupled to the heat source and another side is thermally coupled to the heat dissipation device. The controller periodically samples the temperature sensors and dynamically switches the thermoelectric module between a power generation mode in which the thermoelectric module uses the temperature difference between the heat source and ambient to charge the energy storage device, a cooling mode in which the thermoelectric module is powered to create a voltage difference across the thermoelectric module to cool the heat source, and an idle mode. The thermal management system can be integrated into a portable electronic device, for example a portable computing device.
