High-Resolution Imaging of Intracellular Calcium Fluctuations Caused by Oscillating Microbubbles.
Ultrasound in Medicine and Biology, 2020 Ultrasound insonification of microbubbles can locally enhance drug delivery, but the microbubble-cell interaction remains poorly understood. Because intracellular calcium (Cai2+) is a key cellular regulator, unraveling the Cai2+ fluctuations caused by an

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler
Advanced Materials, EarlyView.An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...
