This invention discloses the application of an electrode material for reducing intracellular resistance genes in drug-resistant bacteria. A platinum-doped dendritic TiO2 nanowire structure based on a three-dimensional material is formed by growing a micron-sized TiO2 backbone array and platinum-doped nano-sized TiO2 branches on the surface of a porous electrode. The prepared dendritic nanowire three-dimensional electrode material has a larger specific surface area, providing more reactive sites and strong electric field sites. Platinum doping enhances the conductivity and electrocatalytic performance of the nanowires. Furthermore, by combining it with chloride salts / oxidants, the electroporation and electrocatalysis of the nanowire electrode surface are coupled. The strong electric field confined at the nanowire tip induces perforation of the drug-resistant bacterial cell structure, strengthening the contact and reaction between the oxidant and the resistance gene. The high electrocatalytic activity confined at the nanowire tip induces the generation of strong oxidizing free radicals, achieving the goal of destroying the drug-resistant bacterial cell structure and efficiently reducing intracellular resistance genes.

This invention discloses a low-temperature polyether demulsifier for oil and gas gathering and transportation and its preparation method, relating to the field of petrochemical technology. The key technical points include: using cashew nut shell powder, pentaethylene hexamine, and bisphenol F in a specific molar ratio as an initiator, and preparing a composite initiator via formaldehyde condensation; incorporating propylene oxide and ethylene oxide through staged block copolymerization to form a polyether backbone; introducing fluorinated epoxy monomers for end-fluorination modification; and finally, performing chain extension and crosslinking with adipic acid and epichlorohydrin to obtain a demulsifier with a molecular weight of 8000~12000 Da, a fluorine content of 5.5~6.5 wt%, and a PDI ≤ 1.3.
