Unraveling the Formation Mechanism of Environmental Amorphous Phases: Insights from Amorphous Ferric Arsenate
A research team from the School of Earth System Science at Tianjin University investigated amorphous ferric arsenate (AFA), a key mineral phase controlling arsenic sequestration in environmental systems. Using in situ synchrotron-based small-angle X-ray scattering (SAXS), the team directly monitored the precipitation process of AFA and identified a previously unrecognized two-stage nonclassical formation ...

Isotopic Tracing of Atmospheric Mercury Transfer Across Earth’s Spheres and Future Evolution
Professor Sun Ruoyu’s team at Tianjin University’s Isotope Frontiers Science Research Center made progress on atmospheric Hg stable isotopes. Their study has been published in the prestigious Earth-Science Reviews journal.Mercury (Hg) is a persistent pollutant with global consequences, posing significant threats to both ecosystems and human health. The atmosphere serves as the main medium for the ...

Mineral Substrates as Evolutionary Drivers of Soil Microbial Diversity through Rare Biosphere
A research team led by H. Hnery Teng at the School of Earth System Science, Tianjin University, collected soil samples from three typical agricultural regions to establish initial microbial communities. In nutrient-rich culture media, they introduced six types of minerals—including nutrient-rich minerals/rocks (olivine, granite, diorite) and nutrient-poor minerals (quartz, kaolinite, montmorillonite)...

Critical but Underquantified Component of the Global Carbon Budget Constrained by Multiple Isotopic Evidence
Tianjin University research team recently combined hydrogeochemical surveys, stable isotopes, clumped isotopes, and radiocarbon analyses to systematically reveal the biogeochemical cycling patterns of methane in urban waters during freeze-thaw events. The findings were published in Water Research (Nature Index journal), with Han Jiaxu (2025 Master’s graduate) as the first author, Dr. Wang Xinchu as ...
