A gas sensor has a sensing structure that is used for generating, for a variety of gases, multiple corresponding electric signals. It has a plurality of measuring electrodes and a gas-sensitive film coating the measuring electrodes; and a micro-heating structure that is used for providing different heating temperatures for the sensing structure, and a silicon-based substrate and a heating layer disposed on the silicon-based substrate. The heating layer integrates heating electrodes of different sizes or different layouts to form a plurality of heating regions of different temperatures, and the plurality of measuring electrodes are respectively disposed in the corresponding heating regions. By integrating heating electrodes of different sizes or different layouts on a single micro-heating structure to form heating regions of different temperatures, a complex atmosphere detection function of a variety of sensing materials at different temperatures is achieved.

A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.

Described are a low temperature plasma reaction device and a hydrogen sulfide decomposition method. The reaction device includes: a first cavity; a second cavity, the second cavity being embedded inside or outside the first cavity; an inner electrode, the inner electrode being arranged in the first cavity; an outer electrode; and a barrier dielectric arranged between the outer electrode and the inner electrode. The hydrogen sulfide decomposition method includes: implementing dielectric barrier discharge at the outer electrode and the inner electrode of the low temperature plasma reaction device, introducing a raw material gas containing hydrogen sulfide into the first cavity to implement a hydrogen sulfide decomposition method, and continuously introducing a thermally conductive medium into the second cavity in order to control the temperature of the first cavity of the low temperature plasma reaction device.

The present disclosure relates to a carbon-based porous material microscopically exhibiting a three-dimensional cross-linked net-like hierarchical pore structures with micropores nested in mesopores that are in turn nested in macropores. Such material provides for accelerated adsorption and desorption rates and lower desorption temperatures for recovery of organic gas molecules.
