Scientists observed semi-Dirac fermion for the first time, and scientists from Pennsylvania State University and Columbia University joined hands to observe a special kind of quasi-particle-semi-Dirac fermion for the first time. Such quasi-particles have mass when moving in one direction, but lose mass when moving in the other direction. The researchers said that in-depth research on these quasi-particles is expected to promote the development of next-generation batteries, sensors and other technologies.

CICC released a research report saying that the CPI and core CPI of the United States both rose to 0.31% in November, which was basically in line with the market and its expectations. For the post-election policies, if the immigration and tariff policies are too radical, it will bring pressure to inflation at the end of next year, which will have an impact on the market and even the mid-term elections. Therefore, before the mid-term elections, due to the "realistic constraints" of inflation, the inflation policy will be faster, but the scope may be limited, while the growth policy will be faster, and then the overall assets will still be positive. According to the difference between the natural interest rate and the real interest rate, CICC estimates that after the interest rate cut in December, there may still be two or three interest rate cuts in 2025, with the end point of interest rate cut at 3.5-3.75% and the center corresponding to long-term US debt at 3.8-4%.In recent years, the installed capacity of new energy generation in China has increased rapidly, and the demand for new energy storage and other regulatory resources has also increased. The energy storage development track is competing with each other, and the total output value of the industry will reach trillion level. In many new energy storage routes, lithium-ion batteries occupy more than 90% of the energy storage, and they are firmly in the first place; All-vanadium redox flow battery has high hopes because of its advantages of high safety, long life and expansibility, and has a good application prospect in the field of large-scale energy storage. This year, Sichuan Province issued the first national special policy to support the development of vanadium battery industry, Panzhihua City, Sichuan Province put forward the vision of building "China Vanadium Power Capital", and the demonstration project of all-vanadium liquid energy storage power station with commercial lease mode was launched here. In November, the project completed the bidding for the procurement of all-vanadium flow battery equipment, which has benchmarking significance for the integration and development of vanadium energy storage industry and financial services industry.
