With the long-term on-orbit operation of the China Space Station, using nanosatellite swarms for cooperative observation of its external structures has become an important technical direction for enhancing in‑orbit monitoring capabilities. However, the space station itself has a non‑spherical complex geometry (e.g., protruding structures such as modules and docking ports) and may perform attitude maneuvers (e.g., sun‑pointing) during orbital flight, making it a dynamic obstacle with both intricate shape and rotational motion relative to the nanosatellites. Traditional artificial potential field obstacle avoidance methods mostly simplify obstacles as spheres or ellipsoids, which cannot accurately characterize the composite geometric features of the space station, and usually ignore the obstacle's own rotational motion. This leads to difficulties in constructing the repulsive potential field, limited maneuvering space, and, more critically, a lack of rigorous theoretical proof to guarantee closed-loop system stability and collision avoidance. Therefore, developing a nanosatellite formation control method that can handle rotating non‑spherical obstacles while providing strict stability guarantees is of significant theoretical importance and engineering value for ensuring safe fly-around and efficient cooperative observation in the vicinity of the space station.

To accelerate the transition to sustainable transport, researchers from Nanjing University of Information Science and Technology and Eindhoven University of Technology investigated what motivates vehicle owners to replace their cars. By applying a Push-Pull-Mooring framework to 803 Chinese drivers, the study reveals that fuel vehicle owners are driven by pragmatic economic factors, while current electric vehicle owners are held by deep-seated habits and social reinforcement.

Reliable temperature sensing above 1000 °C remains difficult because conventional thermistor ceramics often suffer from nonlinear response and resistance drift during prolonged thermal exposure. Researchers developed Mo-regulated high-entropy niobate ceramics to coordinate local lattice distortion, carrier transport, and grain–grain-boundary energy barriers. The optimized ceramic delivered highly linear sensing from −50 to 1250 °C (R² = 0.99907), a B-value fluctuation of only 4.44%, and a stabilized-stage resistance drift of 1.09% after 1000 h at 1250 °C, showing the potential for hypersonic vehicles, aero-engines, and other extreme-temperature systems.

Ferroelectric materials are indispensable for next‑generation non‑volatile memories, sensors, and microwave devices. Among them, SrBi₂Ta₂O₉—a lead‑free Aurivillius‑phase layered compound—offers ultra‑low leakage current along the out‑of‑plane direction, yet its inherent structural anisotropy severely limits the in‑plane ferroelectric response in randomly oriented ceramics. Now, researchers at Harbin Institute of Technology have developed a synergistic strategy combining grain texturing and calcium doping to simultaneously boost the in‑plane remnant polarization and suppress in‑plane leakage, paving the way for high‑performance SrBi₂Ta₂O₉‑based devices.

Electromagnetic wave absorbers often face a fundamental challenge in balancing impedance matching with dielectric loss, limiting their broadband absorption performance. To overcome this limitation, Researchers developed lightweight SiC-based fibrous ceramic membranes by integrating electrospinning with the polymer-derived ceramics (PDC) route through precise control of the precursor composition and pyrolysis conditions. The optimized material achieved a minimum reflection loss of −27.12 dB and an effective absorption bandwidth of 8.22 GHz with a thickness of only 2.7 mm. By establishing a clear composition-structure-property relationship, this work provides a practical strategy for designing next-generation lightweight, broadband electromagnetic wave absorbers with significant potential for aerospace, stealth technology, and electromagnetic protection.

Vat photopolymerization (VPP) faces challenges in manufacturing high-precision, high-quality, high-strength, low-shrinkage ceramic cores from high-solid-loading and high-viscosity ceramic slurries. In this work, a silica-based ceramic slurry using spherical powders at a solid loading of 71 vol% was formulated, and correspondingly established a novel temperature-field assisted vat photopolymerization (TF-VPP) manufacturing process. This method effectively achieved uniform stair-stepping effects in the TPMS structure and high-precision fabrication of fine micropore features (minimum size: 50 μm). The proposed TF-VPP coupled with vacuum debinding fabricates large-size (108.71mm) silica-based ceramic cores featuring low shrinkage and superior comprehensive properties.

Researchers have developed CogDrive, a cognition-driven framework that helps autonomous vehicles anticipate uncertain human behaviors and make safer decisions in mixed traffic. By integrating multimodal trajectory prediction with safety-aware planning, the system models interaction semantics such as yielding and merging while maintaining robust fallback strategies. Tests on large-scale datasets demonstrate improved prediction accuracy and smoother, more reliable driving performance in dense urban environments.
