How to build a circular economy for rare-earth elements
Rare-earth elements (REE) that are crucial for clean-energy technologies are jealously fought over. Policies and programmes to encourage recycling and recovery could reduce tensions. Here we propose a research perspective on a circular economy for REE with three pillars.
Adaptive constraints by morphological operations for single-shot digital holography
We propose an advanced iterative phase retrieval framework for single-shot in-line digital holography that incorporates adaptive constraints, which achieves optimized convergence behavior, high-fidelity and twin-image-free reconstruction.
