Abstract: The present disclosure provides an artificial cell for single-cell mass spectrometry (SCMS) measurement and a preparation method thereof. In the present disclosure, the artificial cell includes an internal aqueous phase, an intermediate oil phase, and an external aqueous phase; where the internal aqueous phase includes polyethylene glycol (PEG) and a polyvinyl alcohol (PVA) aqueous solution, and the intermediate oil phase includes a chloroform-hexane mixture of L-?-phosphatidylcholine; and the external aqueous phase includes PVA and an F-68 aqueous solution. Compared with natural cell samples, new artificial single cells based on microfluidic self-assembly provided by the present disclosure have better uniformity, stability, and controllability. The artificial cell can effectively avoid significant measurement differences between individual single-cell samples, and effectively solve the problem of difficulty in stably preserving biological samples.

Abstract: The present invention relates to a connection device of a high-voltage power supply and an X-ray tube, and a corresponding X-ray source. The connection device comprises a first connecting unit a second connecting unit, the first connecting unit is mounted on a high-voltage power supply and connects a high-voltage power output terminal of the high-voltage power supply, and the second connecting unit is mounted on an X-ray tube and connects a cathode of the X-ray tube. By mounting the first connecting unit and the second connecting unit on the high-voltage power supply and the X-ray tube, and detachably plugging said units together, the high-voltage power supply and the X-ray tube can be connected together. Moreover, the high-voltage power supply and the X-ray tube can be separated so that disassembly for repair can be carried out when any one of the high-voltage power supply and the X-ray tube is faulty.

Abstract: A device and method for reinforcing recycled aggregate based on in-situ C—S—H production including a first, second, third chamber, and a blast drier. A spray structure arranged on the top of the third chamber; the first and second chamber connected to the spray structure through pumps. A hollowed container arranged at the bottom of the spray structure. A certain gap reserved between the bottom of the container and the bottom of the third chamber, the bottom of the third chamber is provided with at least one drain outlet; the blast drier connected to the bottom of the third chamber, and a cover is arranged on the top of the third chamber. The first chamber contains calcium hydroxide solution. The second chamber contains a mixed solution of TEOS, water and anhydrous ethanol. The container is arranged in the third chamber, and the container is used to contain to-be-treated recycled aggregate.
