Astronomical adaptive optics: a review

open access: yesPhotoniX
Since the concept of adaptive optics(AO) was proposed in 1953, AO has become an indispensable technology for large aperture ground-based optical telescopes aimed at high resolution observations.

Plasmonic‐Strain Engineering of Quantum Emitters in Hexagonal Boron Nitride

open access: yesAdvanced Materials Interfaces, EarlyView.
Hexagonal boron nitride (hBN) defects attract interest for single‐photon emission in quantum technologies. This study presents an hBN‐gold nanocone platform to engineer emission centers. The findings reveal emission overlap with gold fluorescence, complicating attribution.

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

Pick‐and‐Place Grippers with Tunable Adhesion from Capped Soft Hollow Pillar Structure

open access: yesAdvanced Materials Technologies, EarlyView.
Mushroom‐shaped soft hollow pillars (SHPs) with a mushroom cap, or capped SHPs (C‐SHPs) are introduced for improved tunable adhesion under pneumatic actuation. The mushroom cap optimizes stress distribution and alters crack initiation on the contact interface, leading to significantly improved adhesion strength and tunability.
