Artificial Compound Eye for Clear Vision in Harsh Environment

open access: yesAdvanced Functional Materials, EarlyView.
Artificial compound eye (CE) with exceptional imaging and motion tracking capturing the movement of a spider and swinging thread with a wide field of view. Surface modifications ensure clear vision of alphabetic letters in rain and fog. Images captured in fog with CE remains visible 3 times longer than simple eyes (SE).

Ultrabroadband Chiral Emission from Cu Nanocluster Eggshell Membrane/CsPbBr3 QD Composites with a Cholesteric Superstructures

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel wide‐bandwidth circularly polarized luminescence (CPL) system combining Cu nanoclusters, perovskite quantum dots, and cholesteric liquid crystals. The design achieves strong CPL emission across 480–750 nm (glum up to 1.31 at 514 nm and 1.46 at 620 nm). Using biomaterials and a simple structure, it offers a promising strategy

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

open access: yesAdvanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.
