Latest Patents

One of Zhaoxia Dong's latest patents is titled "Aqueous carbon dioxide foam stabilized by organic Janus nanosheets and preparation method and application thereof." This invention involves a preparation method that includes several steps. The first step subjects molecules with a hydrophobic tail to spontaneous and ordered arrangement in a mixture of ethanol and water. The second step adds molecules with a hydrophilic head to the solution and adjusts the pH value to 6.0-6.5 for the synthesis of organic Janus nanosheet monomers. The third step involves adding ethanol to the solution and performing a heating reflux while adjusting the pH value to 7.0-8.0. Finally, sodium ethylate is added, and the mixture is heated under an inert atmosphere to complete the reaction.

Another notable patent is the "Method of nano-armored foam reinforced geological storage of carbon dioxide." This method provides a systematic approach to injecting various slugs into geological storage formations. The process includes injecting a pre-CO2 slug, a surfactant foam slug, and a nanoparticle-enhanced foaming liquid slug successively. The nanoparticle-enhanced foaming liquid is tailored based on reservoir characteristics, allowing for the generation of nano-armor reinforced CO2 foam underground. This innovation aims to improve the geological storage capacity of carbon dioxide.
