Millions of tons of pesticides are used each year to protect crops, but traditional formulations release too quickly, degrade easily, and leach away, leading to low efficiency and environmental risks. Compared with the costly and time-consuming development of new pesticides, creating smart controlled-release formulations from existing ingredients is a simpler and more effective way to improve efficiency and reduce ecological harm.
A research team led by Prof. YANG Liangbao from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has introduced a new approach to fabricating clean, open-structured yo-yo-shaped nanoparticles in ultra-dilute colloids. This strategy, which combines solvent washing and chloride ion substitution, enables high-sensitivity and high-stability quantitative detection using Surface-Enhanced Raman Spectroscopy (SERS).
Recently, a research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, have constructed a copper single atom catalyst (Cu-N3 SAs) with an N coordination structure using two-dimensional g-C3N4 derived from melamine pyrolysis as a carrier, achieving efficient electrocatalytic urea synthesis under mild conditions.
A research team led by Prof. SHAO Ding-Fu at the Institute of Solid State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has unveiled a new mechanism for achieving strong spin polarization using antiferromagnetic metal interfaces.
Recently, the research team led by Prof. LI Hai at the Institute of Health and Medical Technology, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has developed a novel deep learning framework that significantly improves the accuracy and interpretability of detecting neurological disorders through speech.
