Radar interferometry and its application to changes in the Earth's surface
Geophysical applications of radar interferometry to measure changes in the Earth's surface have exploded in the early 1990s. This new geodetic technique calculates the interference pattern caused by the difference in phase between two images acquired by ...

The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...

Deep Learning for Mapping Tropical Forests with TanDEM-X Bistatic InSAR Data
The TanDEM-X synthetic aperture radar (SAR) system allows for the recording of bistatic interferometric SAR (InSAR) acquisitions, which provide additional information to the common amplitude images acquired by monostatic SAR systems. More concretely, the

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...
