Wind plays an overlooked role in ecosystem water-use efficiency

Peer-Reviewed Publication

Wind does more than sway trees. It also plays an important role in determining an ecosystem’s water-use efficiency—defined as the amount of carbon an ecosystem absorbs per unit of water lost. Water-use efficiency is an important measure of how ecosystems balance growth and water availability. A research team led by Prof. FU Zheng at the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences has revealed a previously overlooked role for wind in regulating ecosystem water-use efficiency.

Peer-Reviewed Publication

A research team led by Prof. DONG Jinwei from the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences, together with international collaborators, has mapped global croplands reclaimed from wetlands from 2000 to 2022 and evaluated their crop production performance and flood exposure risk.

Study calls for locally tailored wastewater reuse in China

Chinese Academy of Sciences Headquarters
Peer-Reviewed Publication

Wastewater reclamation is increasingly regarded as an alternative water source to mitigate water scarcity in China. However, expanding wastewater treatment capacity alone may not be enough to ease this scarcity, since wastewater supply, treatment facilities, and reuse demand are not always geographically aligned. These findings were highlighted in a new study led by Prof. SHEN Lei from the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences, which was published in Nature Water.

Peer-Reviewed Publication

Prof. LIU Zhongmin's team from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) have developed two new zeolite-catalyzed carbonylation reactions, converting propene into isobutyric acid and ethene into propionic acid—without precious-metal catalysts or organic ligands.

Highly efficient dual-channel doublet emission in lanthanide cerium(III) complex

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS

Researchers report highly efficient dual-channel doublet emission from open-shell cerium(III) complexes. Increasing the coordination number from seven and eight to nine creates a crowded yet adaptable environment that undergoes photoinduced structural relaxation, giving access to two emissive 5d states. The nine-coordinate complexes emit through both channels with photoluminescence quantum yields of up to nearly 100%, offering a design strategy for advanced multichannel luminescent materials.

Peer-Reviewed Publication

Manipulating high-dimensional structured light is crucial for next-generation informatics, yet traditional systems remain bulky and lack reconfigurability. The research team led by Prof. Minming Zhang developed a fully tunable silicon-integrated meta-generator merging waveguide mode multiplexing with multi-channel coherent control. This chip achieves dynamic generation and full-surface coverage across multiple Poincaré spheres, successfully mapping on-chip modes to free-space structured fields for advanced optical communications and quantum technologies.
