Harnessing Carbon‐Containing Materials for Next‐Generation High‐Temperature Electromagnetic Wave Absorbers

Carbon Energy, Volume 8, Issue 2, February 2026.
Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...

Flight Control of a Novel Distributed Tiltrotor UAV With Experiments

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
Considering the mode transition control of a novel distributed tiltrotor UAV, we designed a fast fixed‐time sliding mode attitude controller to improve the response speed and robustness of the control system. Furthermore, a smooth mode transition strategy is developed to guarantee the stable conversion between fixed‐wing and helicopter modes ...

An Online Trajectory‐Planning Guidance Method for Reentry Vehicles With Bézier Curve–Based Shaping Approach

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
To improve the real‐time capability and adaptability of online trajectory‐planning guidance for reentry vehicles, a guidance method based on a Bézier curve shaping approach is proposed. Leveraging the inherent boundary condition satisfaction and smoothness characteristics of Bézier curves, both longitudinal and lateral guidance are designed.
