B[China has recently made a series of progress in the field of uranium extraction materials from seawater: for the first time, discrete molecular topology design was introduced into a porous organic cage system and the phosphoric acid functionalized material PhosCage was synthesized] September 2, according to the Qingdao Institute of Bioenergy and Processes, Chinese Academy of Sciences, the research team of the institute has recently made a series of progress in the field of uranium extraction materials from seawater. For the first time, the team introduced discrete molecular topology design into a porous organic cage system, synthesized the phosphoric acid functionalized material PhosCage, and further combined it with aramid nanofibers to prepare composite airgel microspheres AC-POC with high selectivity, high capacity and anti-biofouling capabilities. Relevant results were published in the international academic journals "Journal of Hazardous Materials" and "Separation and Purification Technology". The Qingdao Institute of Energy Research team proposed a discrete molecular topology design strategy to directionally construct phosphoric acid adsorption clusters in the interlayer nanospace of porous organic cages, and prepared the first phosphoric acid functionalized porous organic cage material - PhosCage. Under laboratory conditions, PhosCage can reach adsorption equilibrium in just 5 minutes; in real seawater samples from multiple sea areas, its maximum uranium extraction capacity reaches 50.4 mg/g, which is 8.4 times the relevant benchmark of the U.S. Department of Energy. B[General Administration of Customs releases customs clearance facilitation measures for the 9th China International Import Expo] September 2nd, the General Administration of Customs recently issued the "Customs Clearance Instructions for the 9th China International Import Expo in 2026" and "Customs Support Facilitation Measures for the 9th China International Import Expo in 2026". Based on summarizing the regulatory service experience of the previous eight CIIEs, it launched a series of customs clearance facilitation measures to fully escort the smooth holding of the 9th China International Import Expo. The two sets of documents issued this time clarify the operational specifications around the entire chain of exhibit entry declaration, inspection and supervision, and post-exhibition disposal. They focus on the actual pain points of overseas exhibitors, optimize the customs clearance process, simplify the approval procedures, implement supporting policies such as tax incentives for exhibits, guarantee models, inspection and quarantine convenience, and reduce the institutional costs of exhibitors.
