During the preliminary design phase of flapping-wing micro air vehicles (FWMAVs), there currently exists a deficiency in rapid prediction method for the aerodynamic characteristics of flexible flapping wings. A novel aerodynamic prediction method for flexible flapping wings has recently achieved significant breakthroughs. This method innovatively employs conical surface to mimic wing deformation, combined with an unsteady panel method for aerodynamic force computation, enabling rapid and accurate prediction of both aerodynamic characteristics and control moments of flexible flapping wings.
An international research team has advanced an imaging method to capture nanoscale “spin maps” of chiral perovskites for the first time, revealing how these materials control electron spin at room temperature. The study also identifies a new type of spin-sensitive junction at the interface with metals. The findings, recently published in National Science Review, could guide the design of next-generation spintronic devices.
High-temperature superconductivity has long been hailed as the “crown jewel” of condensed matter physics. In 2023, the nickel-based compound La3Ni2O7 was found to exhibit superconductivity above 80 K under high pressure, setting a new record for nickelates and opening a fresh platform to explore high-Tc mechanisms. Professors Kun Jiang (Institute of Physics, CAS) and Fu-Chun Zhang (Kavli Institute for Theoretical Sciences, UCAS) and their team proposed that La3Ni2O7 can be described as a “self-doped molecular Mott insulator,” where strong correlations and interlayer coupling drive superconductivity in a way reminiscent of cuprates. This work provides new insights into the origin of high-temperature superconductivity.
Lithium–sulfur (Li–S) batteries require efficient catalysts to accelerate polysulfide conversion and mitigate the shuttle effect. However, the rational design of catalysts remains challenging due to the lack of a systematic strategy that rationally optimizes electronic structures and mesoscale transport properties. In this work, we propose an autogenously transformed CoWO4/WO2 heterojunction catalyst, integrating a strong polysulfide-adsorbing intercalation catalyst with a metallic-phase promoter for enhanced activity. CoWO4 effectively captures polysulfides, while the CoWO4/WO2 interface facilitates their S–S bond activation on heterogenous catalytic sites. Benefiting from its directional intercalation channels, CoWO4 not only serves as a dynamic Li-ion reservoir but also provides continuous and direct pathways for rapid Li-ion transport. Such synergistic interactions across the heterojunction interfaces enhance the catalytic activity of the composite. As a result, the CoWO4/WO2 heterostructure demonstrates significantly enhanced catalytic performance, delivering a high capacity of 1262 mAh g−1 at 0.1 C. Furthermore, its rate capability and high sulfur loading performance are markedly improved, surpassing the limitations of its single-component counterparts. This study provides new insights into the catalytic mechanisms governing Li–S chemistry and offers a promising strategy for the rational design of high-performance Li–S battery catalysts.
The research team found that the supplementation of n-3 fatty acids significantly enhances lactation performance even in non-inflammatory states, suggesting the existence of an unexplored direct regulatory mechanism.
