The invention provides a VOCs treatment method based on liquid metal carbon sequestration, and the VOCs treatment method comprises the following step: under energy excitation, VOCs and liquid metal are subjected to a contact reaction. According to the method for treating the VOCs through the liquid metal, the VOCs can be directly converted into solid carbon, secondary pollution products such as dioxin are avoided, the problem that active sites are coked and inactivated is avoided, operation is easy, the treatment effect is good, and the application value is high.

The invention discloses a kit for joint detection and a preparation method thereof, and relates to the field of medical detection. The kit for joint detection comprises a magnetic bead coated with a capture antibody, an enzyme-labeled antibody compound, a fluorescein-labeled antibody and a luminous substrate, and the magnetic bead coated with the capture antibody comprises a first antibody specifically bound with Tau217 and a first antibody specifically bound with NfL. The method comprises the following steps: mixing and incubating an object to be detected with captured antibody-coated magnetic beads, an enzyme-labeled antibody compound and a fluorescein-labeled antibody, injecting 630nm exciting light into an instrument, automatically collecting a light signal 1, carrying out a contact reaction on the compound and a luminous substrate, automatically collecting a 470nm light signal 2 emitted by an enzyme catalysis substrate by the instrument, and determining whether the light signal 2 is 470nm or not. The content of two to-be-detected substances, namely Tau217 and NfL, is identified through different optical signals, two items, namely phosphorylated Tau 217 and neural light chain protein, are jointly detected, the detection sensitivity is improved, the time required by the two items of detection is shortened to the time required by one item of detection, and the detection efficiency of the Alzheimer's disease marker is improved.

This invention relates to the field of gas-liquid reactions, specifically to a method for gas-liquid two-phase contact reactions. The method is carried out in a shell-and-tube microbubble reactor, which includes a shell and a tube located within and penetrating the shell. The tube wall has holes for the limited passage of gaseous feedstock. The two ends of the tube penetrating the shell are a gaseous feedstock inlet and an unreacted gaseous feedstock outlet, respectively. The shell has a liquid feedstock inlet and a product outlet. The method includes: introducing gaseous feedstock into the tube of the shell-and-tube microbubble reactor, and entering the shell side through the holes in the tube wall to react with the introduced liquid feedstock. This invention, by employing a specially structured shell-and-tube microbubble reactor for gas-liquid two-phase reactions, greatly enhances the gas-liquid reaction process.
