Filtering of quantum states with plasmonic metamaterial absorber

, 2019
We use single-photon interference on a metamaterial absorber to demonstrate quantum state filtering by dissipation, exploiting the metamaterial’s ability to distinguish between symmetric and anti-symmetric superpositions of a two-path wave ...

Continuous and Large‐Scale: ELEANOR, the Soft Architected Arm Inspired by the Elephant Trunk

Advanced Intelligent Systems, EarlyView.
A large‐scale, architected continuum robot inspired by the macroscopic properties of the African elephant trunk achieves adaptive elephant‐like movements and whole‐body grasping. The results demonstrate that designing from the natural system’s macroscopic properties, rather than prescribing behaviors, provides a powerful strategy for developing ...

Highly Polarized 1,4‐Dihydropyrrolo[3,2‐b]Pyrroles: From Synthesis to Photophysics and Two‐Photon Induced Polymerization

Chemistry – A European Journal, EarlyView.
Quadrupolar, centrosymmetric 1,4‐dihydropyrrolo[3,2‐b]pyrroles (DHPP) possessing two five‐membered rings and highly polarized architecture are not emissive, but they are good photosensitizers in two‐photon induced polymerization. ABSTRACT A series of ladder‐type, highly polarized functional dyes possessing 1,4‐dihydropyrrolo[3,2‐b]pyrrole (DHPP ...
