This invention provides a method for synthesizing dimethyl carbonate, belonging to the field of carbonate compound synthesis technology. The synthesis method of this invention does not require high temperature and high pressure conditions, and can be carried out at room temperature and pressure, significantly reducing energy consumption and equipment requirements. By coupling the reduction and oxidation reactions of photoelectrochemical carbon dioxide conversion, the synthesis energy barrier of dimethyl carbonate is lowered, improving energy utilization efficiency. Using greenhouse gas carbon dioxide as the main raw material, waste resource utilization is achieved, and the energy used is clean energy such as solar or electrical energy, avoiding pollution at the source. This invention couples the carbon dioxide conversion and dimethyl carbonate synthesis steps, realizing the recycling of the reactant methanol within the system, simplifying the process flow. The combined use of light and electrical energy produces a synergistic effect, improving the reaction rate and the selectivity of dimethyl carbonate.

This invention provides a method for treating high-salinity wastewater using *Chaetoceros muelleri*, belonging to the field of water treatment: *Chaetoceros muelleri* strains in a preservation state are transferred to a nutritionally complete and suitable standard f / 2 culture medium for activation culture under standard f / 2 conditions; actual marine aquaculture wastewater is used as the treatment target, and after filtering out impurities, the salinity of the wastewater is adjusted to 30-35‰; the *Chaetoceros muelleri* treated in step S1 is inoculated into the high-salinity wastewater at 0.05–0.2 g / L (dry weight), and the lighting system is activated after inoculation; during system operation, the algal biomass and changes in ammonia nitrogen, total nitrogen, and phosphate in the water are monitored regularly; when the pollutant removal rate remains stable at a high level and the algal biomass continues to increase, the system can be considered to be operating stably. This invention efficiently removes nitrogen, phosphorus, and other pollutants from wastewater using *Chaetoceros muelleri* technology, while maintaining stable algal growth, thus improving wastewater treatment efficiency and resource utilization rate.

The invention relates to a soothing and bacteriostatic composition and application thereof in shower gel, and belongs to the technical field of cosmetics. The soothing and bacteriostatic composition disclosed by the invention comprises a fermentation substrate and a fermentation strain, wherein the fermentation substrate comprises a sargassum extract, an aesculus chinensis extract and a hemerocallis fulva flower extract; the mass ratio of the sargassum extract to the aesculus chinensis extract to the hemerocallis fulva flower extract in the fermentation substrate is 1: (0.1-0.7): (3-6); the fermentation strain comprises bailey sporospora. The soothing and bacteriostatic composition prepared from the fermentation substrate and the fermentation strain limited by the invention has the advantages of remarkably inhibiting the activity of hyaluronidase and inhibiting the activity of malassezia and propionibacterium acnes, and the soothing and bacteriostatic effects of the shower gel can be remarkably improved when the soothing and bacteriostatic composition is applied to the shower gel.

The present application relates to the technical field of composite forming auxiliary materials, and particularly relates to a breathable release film and a preparation method thereof. The method comprises the following steps: 1) dispersing a polymer and a nano functional filler in a solvent to configure an electrospinning solution; 2) performing electrospinning on a substrate layer to form a nanofiber film; 3) performing functionalization treatment on the surface of the nanofiber film, coating epoxy modified silicone oil and catalyzing curing; and 4) performing post-treatment on the cured material to obtain the breathable release film. The present application constructs a small-aperture PVDF nanofiber film through electrospinning, realizes high breathability, forms a physical anchoring functional layer on the fiber surface through self-crosslinking of the epoxy modified silicone oil, and obtains a stable low-surface-energy resin-repellent interface, thereby breaking through the contradiction between the breathability and the barrier property of traditional materials, and having excellent solvent resistance and moisture and heat aging resistance, and the comprehensive performance is significantly better than that of traditional foaming coatings and PTFE microporous films.
