美国总统特朗普：（关于韩国在美国的投资）我没有在阿拉斯加管道项目上急于行动。

CNN, citing two people familiar with the matter, reports President Trump is expected to appoint Jay Clayton as an AI czar — a presidential adviser on artificial intelligence. Clayton currently serves as Director of National Intelligence. Trump said last month he would name an AI adviser and form an "AI force" but provided no implementation details; this would be his second cross‑agency AI coordinator. Venture capitalist David Sacks held the post early in Trump’s second term and remains an informal AI adviser. The move comes as leading AI researchers warn of risks, while Trump has repeatedly downplayed those risks and opposed tighter regulation.

A team at the Shenyang National Research Center for Materials Science, Institute of Metal Research, Chinese Academy of Sciences proposed a cathode-design approach based on trace-element physico-chemical rules, shifting exploration from empirical trial-and-error toward targeted design. Results published Oct. 1 in Nature Synthesis show multitrace-element co-doping (each element at ~1%) simultaneously improves lithium-ion transport and structural stability. Electrochemical tests: nearly 80% state-of-charge after a 3‑minute ultra-fast charge; 82.4% capacity retention after 350 cycles under 6‑minute fast charge/discharge conditions. A 5.74Ah cell using the material delivered 278.6 Wh/kg at −20°C, indicating strong low-temperature performance and offering a new materials option for cold-region EVs and energy storage.
