Advancing All‐Day Passive Radiative Cooling Performance of 3D Anodized Aluminum Oxide Nanostructures on Aluminium

open access: yesAdvanced Optical Materials, EarlyView.
Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...

Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures

open access: yesAdvanced Optical Materials, EarlyView.
A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...
