Hydrophobic 1D and 3D Anodic Alumina Radiative Coolers on Aluminum: Humidity‐Resilient Daytime Sub‐Ambient Cooling

Advanced Optical Materials, EarlyView.
1D and 3D nanoporous anodic aluminum oxide (AAO) surfaces were functionalized with stearic acid (STA) to increase hydrophobicity and reduce the influence of humidity on radiative cooling performance. The STA coating improves cooling behavior under humid atmospheric conditions (Madrid summer), before while keeping the optical properties required for ...

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

Advanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.
