Abstract: A mobile phase-change heat and cold storage device include heat transfer plates, a bracket, a casing, a main tube, a storage tank, and a phase-change working medium. Heat is stored and released by the phase-change working medium, and the main tube and casing provide an interface between the heat and cold storage device and the outside world. In the process of heat storage, vapor flows through the heat transfer plates via the main tube; heat is transferred to the phase-change working medium via the heat transfer plates, and is transported in a box body to a designated position; cold water flows through the heat transfer plates via the casing; heat is transferred from the phase-change working medium to the cold water via the heat transfer plates to obtain hot water; the phase-change working medium can release heat by exothermic solidification. The process of cold storage is similar thereto.

Abstract: Disclosed in the present invention are methods for preparing a CoNi—S@3D-C nanocomposite and a modified battery separator. The CoNi—S@3D-C material synthesized by the method of the present invention is applicable not only to a lithium-ion battery but also to a sodium-ion battery. As the anode for both the lithium-ion and sodium-ion batteries, it exhibits good energy storage performance, maintaining very stable performance even under high-density current charging and discharging cycles, while also possessing very high reversible capacity. The heteroatom-doped three-dimensional nanocarbon structure achieves good encapsulation of the metal sulfides, and can effectively inhibit the volume expansion of the metal sulfides, slowing down the decline of its specific capacity and maintaining the high capacity and service life of the anode material. The CoNi—S@3D-C material of the present invention can also be used as a material for modifying a separator of a lithium-sulfur battery. The modified separator can improve the safety performance of the lithium-sulfur battery while maintaining a high energy storage effect of the battery and slowing down the capacity decline of the lithium-sulfur battery.

Abstract: An ultra-supercritical (USC) tower-type solar heat absorber includes a grille-hot-plate current-sharing screen, a tube row, and a graphite filling layer. The grille-hot-plate current-sharing screen is assembled by a plurality of grille hot plates. Each of the plurality of grille hot plates includes a liquid-absorbing core and a grille, and is filled with a phase-transition working medium (such as sodium, potassium, and lithium) and pumped to a vacuum state. When sunlight is reflected and concentrated on the grille-hot-plate current-sharing screen, the phase-transition working medium absorbs heat and evaporates on an evaporation surface of a grille hot plate, is condensed on a condensation surface of the grille hot plate, and returns to the liquid-absorbing core through a grille to produce a stable two-phase flow, which allows efficient heat transfer, homogenizes a surface heat-flow density, and greatly reduces a temperature difference and a thermal stress on a surface of the grille-hot-plate current-sharing screen.

Abstract: The invention relates to a molecular peptide mutant, the amino acid sequence of which is as shown in SEQ ID NO: 1. In the invention, SpyCatcher is designed and modified to obtain a molecular peptide SpyCatcher-21 with stimulus response to pH on the basis of not affecting the formation of isopeptide bonds, and Pro is introduced into a key loop of the SpyCatcher-21 through analysis of the crystal structure to reduce the flexibility of the loop and obtain a mutant SpyCatcher-21_A82P, which can raise ligation efficiency with SpyTag. The SpyCatcher-21_A82P can be used to achieve double-enzyme catalysis according to objective needs by changing the pH of the environment to obtain different degrees of coupling, or obtain a three-enzyme coupled catalytic system through electrostatic interaction with a positively charged enzyme.
