Professor Juergen Popp, University of Jena, gives talk at QIBEBT on “Translational Biophotonics”

http://english.qibebt.cas.cn/ne/ns/202310/t20231027_397294.html

On Oct. 27, 2024, Prof. Juergen Popp Speaks, director of the Leibniz Institute of Photonic Technology and chair for Physical Chemistry at Friedrich-Schiller University, gave a talk at QIBEBT Distinguished Expert Forum and Visits Single-Cell Center on “Translational Biophotonics – Raman spectroscopy and AI a game changer !?” Popp elucidated the innovative technologies and potential applications of Raman spectroscopy in biophotonics, particularly its extensive use in clinical diagnostics. He emphasized the potential of multimodal methods combining Raman spectroscopy with other spectroscopic/optical technologies and how Raman can address today’s medical challenges, such as early cancer diagnosis and personalized treatments.

The visit was part of the Sino-German Scientific Partnership Program funded by the National Natural Science Foundation of China.

Nature 2025 science city ranking: six of top 10 in China, Qingdao is 31 between Munich and Berlin

https://www.nature.com/nature-index/supplements/nature-index-2025-science-cities/tables/overall

https://en.people.cn/n3/2025/1118/c90000-20391615.html

The newly released “Nature Index 2025 Science Cities” supplement shows that the number of Chinese cities in the global top ten rose from five in 2023 to six in 2024, marking the first time China holds a majority in the rankings.

The supplement draws on the Nature Index database, which tracks research articles published from 2015 to 2024. Its analysis uses “Share”, a fractional count reflecting institutional contribution to publications, as the primary metric, with time-series data adjusted to 2024 levels. Each city’s Share is calculated by summing the contributions of all affiliated institutions located within that city.

According to the Nature Index, the world’s leading science cities overall are: Beijing, Shanghai, New York metropolitan area (U.S.), Boston metropolitan area (U.S.), Nanjing (China), Guangzhou (China), San Francisco Bay Area (U.S.), Wuhan (China), Baltimore-Washington metropolitan area (U.S.), and Hangzhou (China).

Further analysis shows that Chinese cities hold a strong advantage in chemistry, physical sciences, and earth and environmental sciences, leading the global rankings in all three fields. Notably, Chinese cities claimed all of the top ten positions in chemistry for the first time. In the other two subject areas, they secured six of the top ten spots, with Beijing ranking first worldwide across all three domains.

European cities in the ranking start at 19 (London), followed by Zurich (28), Cambridge (29), Munich (30) and Berlin (32), following Qingdao at position 31.

A new Fischer-Tropsch route which eliminates CO2 formation

https://en.people.cn/n3/2025/1031/c90000-20384954.html

https://www.science.org/doi/10.1126/science.aea0774

A group at Peking University has developed technology that almost completely eliminates carbon dioxide by-products during Fischer-Tropsch synthesis (FTS), offering a new route to green syngas conversion and low-carbon chemical manufacturing. FTS converts the syngas of carbon dioxide and hydrogen into liquid fuels or high-value chemicals such as olefins. It serves as the pivotal bridge for turning coal, natural gas, biomass and other carbon resources into fuels and value-added chemicals.

The researchers have used a sodium-modified FeC_x@Fe₃O₄ core-shell catalyst coupling water-gas shift (WGS) with syngas-to-olefins (STO) to convert water into hydrogen in situ. HAE reaches about 66 to 83%, exceeding that of methanol-to-olefins (MTO, 50% upper limit). The approximately 95% carbon monoxide conversion and >75% olefin selectivity were simultaneously obtained. The coupling effect was validated by isotope tracing with deuterium oxide and blocking the WGS pathway, and the contribution of WGS was quantitatively evaluated. These results, using lower hydrogen to carbon monoxide ratios, implied that reducing steam consumption in the WGS reaction and reducing the overall output of carbon dioxide and wastewater enabled a sustainable STO process for potential industrialization.
