Gate-voltage-controlled topological phase transition achieved in β-Ag2Te, paving the way for a new class of low-power electronics

Science China Press
Peer-Reviewed Publication

Topological phase transition is attracting great attention in condensed matter physics, and its gate-voltage-reversible control is essential for electrically driven topological devices. Recently, Professor Jinxiong Wu’s team at Nankai University achieved the first gate-voltage-reversible topological phase transition in β-Ag₂Te nanodevices, evidenced by a π Berry phase transition. Theoretical attributes this to the Stark effect modulating band structure. Based on this, they built a prototype topological phase transition transistor with on-off ratio exceeding 10⁴, opening a new route for electrically controlled topological devices.

Thiolated biochar helps keep toxic mercury locked in soil under climate-driven wet and dry cycles

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

A new study shows that thiol-modified biochar can maintain long-term mercury immobilization in contaminated soils, even when repeated drying and rewetting mimic heatwave-accelerated weathering.

This is how to beat the tumor cells that survive cancer therapy

University of California - San Francisco
Peer-Reviewed Publication

Cancer drugs can shrink fast-growing tumors. But sometimes a few tumor cells survive. These “persister” cells seed new tumors, forcing cancer patients into arduous cycles of testing and treatment.
