Flight Dynamics Operations of the TanDEM-X Formation

open access: yes, 2012
Since end of 2010 the German TerraSAR-X and TanDEM-X satellites are routinely operated as the first configurable single-pass Synthetic Aperture Radar interferometer in space. The two 1340 kg satellites fly in a 514 km sun-synchronous orbit.

Autonomous Flight with Hierarchical Planning

open access: yesCEAS Aeronautical Journal
Abstract A hierarchical planning method with three levels was demonstrated in simulation and in autonomous flight on a Black Hawk helicopter. The reactive terrain avoidance software has been previously flown and has demonstrated the ability to sense and avoid previously unknown terrain while autonomously guiding the aircraft to a destination ...

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

open access: yesAdvanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

open access: yesAdvanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Suppressing Surface Degradation in Na‐Rich Prussian Blue Cathodes via Liquid‐Phase Dehydration

open access: yesAdvanced Materials, EarlyView.
Gas bubbling in a liquid medium lowers the local water vapor pressure and continuously removes desorbed water, enabling effective dehydration of Prussian Blue without inducing surface oxidation. This interfacial mass transfer‐driven process stabilizes the surface chemistry and improves electrochemical performance, providing a strategy for handling ...
