Lightweight and High‐Performance Ankle Braces Enabled by 3D Printed Metamaterial Liquid Crystal Polymer

open access: yesAdvanced Materials Technologies, EarlyView.
A flexible, lightweight ankle brace made from 3D‐printed liquid crystal polymer metamaterials offers targeted support without restricting movement. Programmable stiffness provides protection during risky motions. Biomechanical tests suggest performance comparable to commercial braces with reduced bulk, highlighting potential for broader orthotic ...

Resonance Energy Transfer and Purcell Effect in a Cu2O/Au Hybrid Optical Antenna

open access: yesAdvanced Photonics Research, EarlyView.
A Cu2O nanosphere mediates efficient (e.g., 70%) resonance energy transfer (RET) to a gold substrate. The RET damping constant derived from single‐particle scattering, ΓRET$\left(\Gamma\right)_{R E T}$, identifies interband transitions in Au. RET also occurs from an excited electron‐hole pair in Au to the Cu2O/Au hybrid resonator mode, followed by ...
