Electroactive Proteinoid–Quantum Dot Systems

open access: yesSmall Science, EarlyView.
Proteinoid‐quantum dot conjugates form toroidal nanostructures (145.2 nm outer diameter, 102.3 nm cavity) via glutamic acid‐phenylalanine‐aspartic acid‐cysteine cross‐linking with sulfo‐SMCC (sulfosuccinimidyl 4‐(N‐maleimidomethyl)cyclohexane‐1‐carboxylate).

Time‐Domain Visualization of Electron‐Phonon Coupling in Nanographenes

open access: yesSmall Methods, EarlyView.
Impulsive vibrational spectroscopy, Raman spectroscopy, and density functional theory calculations are gathered together to unveil elusive low‐frequency collective vibrational modes in dibenzo[hi,st]ovalene nanographenes, enabling the detailed comparison between vibrational modes in derivatives with different peripheral groups.

Topological Polaritonic Metamaterials Realized in Bulk Transition Metal Dichalcogenide Crystals

open access: yesSmall Structures, EarlyView.
Monolithic all‐van der Waals materials‐based polaritonic topological insulators are introduced and demonstrated that support robust boundary modes for extreme confinement and robust propagation of strongly coupled exciton‐photon hybrid particles, which are readily tunable with temperature. These monolithic polaritonic topological metasurfaces can serve

Kirigami Archimedean Polyhedrons with One‐Degree of Freedom Radial Transformation

open access: yesSmall Structures, EarlyView.
A family of kirigami Archimedean polyhedrons is developed based on assemblies of spatial 7R linkages that enable one – degree of freedom radial transformation following diverse spatial symmetries. Furthermore, the reconfigurable kirigami polyhedrons are constructed by superimposed patterns, and the corresponding metamaterials with various thermal ...
