The application relates to the field of biotechnology, and discloses an exosome concentration detection kit, a detachable double-cassette main body, which comprises a cassette-type main body I and a cassette-type main body II; the cassette-type main body I is provided with valve gas transmission pipes on both sides, an internal waste liquid collecting bin and a collecting interface bin are arranged in the inner cavity, an optical detection window is detachably assembled on the top through fixing bolts, a chip card slot is arranged on the opposite surface of the main body II, and a fluorine rubber sealing ring is attached to the inner wall of the card slot; and a reagent bin fixing groove and a sample adding port are arranged on the top of the cassette-type main body II. The mechanical cooperation of the detachable double-cassette main body and the automatic fluid control equipment realizes the pre-packaging and fixing of all complex reagent pipelines in the cassette, the user does not need to manually pipette or connect any pipeline, only three actions of "adding a sample, putting the detachable double-cassette main body, and one-key starting" are needed, and the fluid control equipment can automatically complete puncture, sealing, fluid time sequence control and valve switching of up to 7-8 steps.

The application discloses an oxygen adsorbent and a preparation method and application thereof, and relates to the field of fuel gas deoxygenation. The preparation process of the oxygen adsorbent comprises the following steps: mixing a lanthanum source, a strontium source, an iron source and a titanium source to prepare LSTF precursor powder; loading CeO2 on the LSTF precursor powder; and performing superficial reduction treatment on the LSTF loaded with CeO2, and then loading Fe to prepare an Fe-CeO2-LSTF type adsorbent. The Fe-CeO2-LSTF type adsorbent prepared in the application has a multi-level and reversible oxygen storage network, the network can realize efficient adsorption of oxygen at a low temperature of 100-150 DEG C, and the effect of deep deoxygenation is achieved; and the oxygen can be desorbed at a medium temperature of 220-300 DEG C, and the recycling of the material is realized.

The application belongs to the technical field of concrete impermeable materials, and specifically provides a concrete impermeable material, a preparation method and application thereof, the concrete impermeable material comprises the following raw materials in parts by weight: cement 100-130 parts, microsilica powder 25-40 parts, fly ash 20-25 parts, PBA composite material 10-15 parts, polyurea 7-12 parts, bentonite 5-10 parts, silane coupling agent 2-3 parts, and water reducing agent 1.5-2 parts; the PBA composite material is a core-shell structure with modified chitosan as a shell and Zn-Co nanoparticles as a core. The concrete impermeable material prepared by the application has the advantage of good impermeability.

The present application relates to the technical field of carbon capture, and discloses a direct air carbon capture system and method using automobile engine waste heat. The circulating water in the automobile exhaust heat exchange device heats the engine coolant to increase the temperature of the coolant sent to the absorption-desorption tower. After the air passes through the absorption-desorption tower, the obtained pure carbon dioxide is sent to a gas-liquid separator, and then compressed into a liquid state by a compression device and stored in a storage device. The present application has the advantages of high carbon capture amount, full utilization of engine waste heat, flexibility, long capture time, high plasticity, and completion of carbon dioxide capture during driving, etc. The present application is also suitable for large-scale carbon capture work. Compared with traditional carbon capture plants, the present application does not need to use large fans to guide air flow, reducing the consumption of energy, land and water resources, and promoting the realization of carbon neutralization.
