This invention discloses a G4-DNA tetrahedral probe electrode, its preparation method, applications, and application methods. This invention utilizes four DNA strands to self-assemble into a DNA tetrahedral structure based on Watson-Crick hybridization. The DNA tetrahedron and G4 strand can be connected to the electrode based on the interaction between thiol groups and the gold electrode, and complementary base pairing. The addition of the DNA tetrahedron, through the construction of a reasonable probe density, further improves the detection sensitivity. This invention utilizes square wave voltammetry for electrochemical detection of malachite green. The content of malachite green can be determined based on the strength of the current signal of its characteristic peak. Rapid detection of malachite green can be achieved in a short time, with a minimum detection concentration of 3.65 μg / kg, showing potential for on-site detection. Six repeated tests using this electrode yielded almost identical detection signals, indicating that the electrode has good reusability and stability.

This application relates to the field of wind and solar power generation technology, and provides an integrated energy supply unit. The integrated energy supply unit includes a coordination unit, a wind-solar-storage power generation unit, a thermal energy unit, and a generator set. The wind-solar-storage power generation unit is used for electrical connection to the power grid, converting at least one of wind energy and solar energy into electrical energy and transmitting it to the grid. The generator set is also used for electrical connection to the power grid, converting the thermal energy from the thermal energy unit into electrical energy and transmitting it to the grid. The coordination unit is used to call upon at least one of the wind-solar-storage power generation unit and the thermal energy unit to generate electricity. Electricity can be supplied to the grid through at least one of wind power, photovoltaic power generation, and thermal energy generation to meet grid demand. When the power supply capacity of the wind-solar-storage power generation unit is insufficient to meet grid load demand, the generator set can convert the thermal energy from the thermal energy unit into electrical energy to supplement power generation and respond to grid demand.

This invention belongs to the field of photo-evaporation desalination of water, specifically relating to a composite photoevaporator for photo-evaporation desalination and its preparation method. Carbon nanotubes, which possess excellent light absorption and water transport capabilities, are dispersed in biomass materials. Simultaneously, a layer of copper acetate is sprayed onto the surface of the biomass materials containing carbon nanotubes, forming copper particles after carbonization. The photoevaporator prepared by this invention combines metal, carbon nanotubes, and biomass materials, exhibiting contrasting hydrophilic and hydrophobic properties and strong salt resistance.

The application belongs to the technical field of battery materials, and particularly relates to a high-performance ceramic composite diaphragm as well as a preparation method and application thereof. The preparation method of the high-performance ceramic composite diaphragm comprises the following steps: mixing alumina powder with water, stirring and dispersing for 0.5-1 h, then adding carboxymethyl cellulose solution and a dispersing agent, stirring for 1-2 h, further adding acrylic acidified epoxy soybean oil polyol and a photoinitiator, and stirring for 0.5-1.5 h, so as to obtain ceramic slurry; uniformly coating the prepared ceramic slurry on a polyolefin diaphragm, and placing the coated diaphragm in an oven, and irradiating with a UV light for 2-5 min. The ceramic composite diaphragm prepared by using acrylic acidified epoxy soybean oil polyol as a binder not only can effectively improve the safety of a lithium ion battery by preventing short circuit under high temperature, but also has good infiltration and liquid absorption and retention capacity for electrolyte, so that the performance and service life of the battery can be greatly improved.
