This invention belongs to the field of solar water evaporation technology, and discloses a high-efficiency solar water evaporator, its preparation method, and its application. The preparation method includes the following steps: (1) Clean and dry coconut fibers, take multiple coconut fibers and weave them into a rope, and then cut them into coconut fiber ropes of the same length; (2) Embed the above-mentioned coconut fiber ropes of the same length into a sponge in an m×n array, wherein the lower end of the coconut fiber rope is flush with the bottom surface of the sponge, while its upper end protrudes from the top surface of the sponge by a certain height; (3) Immerse the part of the above-mentioned coconut fiber rope array protruding from the top surface of the sponge in a sodium alginate solution containing carbon black for surface coating treatment, and then take it out and air dry naturally to obtain a high-efficiency solar water evaporator based on a coconut fiber array. This invention has the characteristics of wide material sources, low cost, simple evaporator construction method, and high water evaporation rate, and has better prospects for large-scale preparation and commercial application.

This invention discloses an extracellular polysaccharide DSP-1 from the shell of a deep-sea fungus, *Subseptospora*, and its applications. Didymella keratinophila The fermentation product of SCAU273 was isolated and purified to obtain an extracellular polysaccharide DSP-1. This polysaccharide has a molecular weight of 4116 Da, a bibranched structure, and is mainly composed of glucose polymers. Further studies showed that DSP-1 can enhance the activity and promote the proliferation of RAW 264.7 macrophages over a wide concentration range (25–400 μg / mL). Furthermore, at certain concentrations, it dose-dependently promoted the secretion of NO, TNF-α, IL-6, and IL-1β by RAW 264.7 macrophages, exhibiting good immunomodulatory activity against RAW 264.7 macrophages. It shows broad prospects for the production and widespread application of environmentally friendly marine biological agents.

The invention is suitable for the technical field of functional materials, and provides a fusiform vesicle containing an annular inner wall structure and a preparation method and application thereof.The preparation method comprises the steps that a double-block copolymer with the polystyrene block polymerization degree being 60-150 is prepared, and a double-block copolymer with sulfydryl is obtained through a reduction reaction; carrying out a click chemical reaction with polyoxometallate with a maleimide group, and carrying out separation and purification to obtain a triblock polyoxometallate-polymer covalent heterocomplex; and dissolving the fusiform vesicle in 1, 4-dioxane, dropwise adding deionized water under high-speed stirring until the water content is 16-24%, and fixing the morphology after self-assembly to obtain the fusiform vesicle with the annular inner wall structure. The fusiform vesicles prepared in the invention are hollow fusiform, polyoxometallate in the membrane forms a hexagonal annular inner wall, the size is 50-500 nm, the fusiform vesicles can be regulated and controlled through PS polymerization degree, the morphology is uniform, the structure is stable, and the fusiform vesicles have wide application prospects in the fields of drug delivery, disease diagnosis and the like.
