Researchers have proposed a method for ⁹⁹Mo production via electron accelerator irradiation of a natural-uranium-bearing liquid molten salt target. This approach offers significant advantages, including low nuclear proliferation risk, online extraction capability, and low construction costs. Consequently, it provides a viable pathway for stable, large-scale ⁹⁹Mo production.

A research team from Nanjing University has developed an in-situ on-device electrochemical intercalation method to manipulate the structural and electronic properties of MoS₂ thin flakes, resulting in a robust nonlinear Hall effect (NLHE) observable at room temperature. By intercalating cetyltrimethylammonium ions (CTA⁺) into the van der Waals (vdW) gap of MoS₂, the inversion symmetry is broken and NLHE can be observed up to 300 K. This work provides a new approach for regulating NLHE and symmetry in 2D materials and opens new avenues for designing new electronic and spintronic devices.

The research team of Weihong Tan, Xiaohong Fang, and Tao Bing from the Hangzhou Institute of Medical Sciences, Chinese Academy of Sciences, proposed a new method for nucleic acid aptamer sequence analysis based on machine learning. This method can directly parse the secondary structure of nucleic acid aptamers from single-round screening data, thereby obtaining detailed secondary structure information of nucleic acid aptamers without iterative enrichment. This enables rational truncation and optimization of high-affinity nucleic acid aptamers, and even the design of nucleic acid aptamer molecules, significantly accelerating the discovery and optimization process of nucleic acid aptamers. The article was published as an open access Research Article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.

A joint research team from NIMS, Kyoto Institute of Technology (KIT), Japan Synchrotron Radiation Research Institute (JASRI), University of Hyogo, Tohoku University, and the Technical University of Darmstadt, developed a novel materials design approach that achieves a giant cooling effect and excellent durability in magnetic cooling materials whose temperature changes when a magnetic field is switched on and off. The team found that, by precisely controlling the chemistry of covalent bonds within the unit cell can reshape the energy landscape of the phase transition, thereby eliminating hysteresis and its associated irreversible energy losses. Based on this finding, the team achieved a rare combination of giant cooling effect and excellent cyclic stability. This research result paves a new pathway toward energy-efficient magnetic cooling technology and was published in Advanced Materials on December 18, 2025.

MIT engineers identified a common polymer whose thermal conductivity changes quickly and reversibly when the material is stretched. The material could be used to engineer systems that adapt to changing temperatures in real-time, such as switchable fibers woven into apparel.
