Calibration and Clutter Cancellation Techniques for Accurate Wideband Radar Cross Section Measurements [PDF]

, 2021
The expected received power is a key design parameter when designing a radar system. The radar’s receiver must be sensitive enough to detect the object of interest without being saturated by the highest received power. The object of interest’s visibility

Bioadhesive‐Integrated 3D‐Printed Multilayer Scaffolds Secure a Mechanically‐Stable Osteoimmune Niche for Enhanced Bone Augmentation

Advanced Science, EarlyView.
A 3D‑printed multilayer adhesive scaffold, firmly anchored to bone defects by simple finger pressing, suppresses micromotion and secures mechanical stability of the osteogenic niche. This stabilization likely contributes to the enhanced bone augmentation by fostering a pro‑regenerative mechano‐immune profile—characterized by M2‑like macrophage ...

Reusable Polyphenol Building Blocks Enable Recyclable Epoxy‐Amine Thermosets via Methanolysis

Angewandte Chemie, EarlyView.
A biobased epoxy–amine platform was developed using functional building blocks derived from polyphenols. These thermosets exhibited tunable mechanical and thermal properties, together with efficient, catalyst‐free chemical recycling via methanolysis. Beyond the recovery of reusable building blocks, the recycled polyols could be further upcycled into ...
