Soft Colloidal Robots: Magnetically Guided Liquid Crystal Torons for Targeted Micro‐Cargo Delivery

Small, EarlyView.
Torons, topological quasiparticles in liquid crystals, can be propelled using electric fields and precisely steered with magnetic alignment, enabling programmable motion without fluid flow. In microfluidic channels, they transport colloidal cargo and exhibit novel dynamic behavior. Their uniformity, softness, and reconfigurability make torons ideal for

Synergistic Pyroelectric‐Bolometric Coupling in Tellurene Nanowire for Energy‐Efficient Artificial Vision

Small, EarlyView.
Synergistic pyroelectric–bolometric coupling in Tellurene nanowires enables efficient photothermal conversion and self‐driven synaptic functionality. Edge‐induced polarization and temperature‐dependent resistance cooperatively generate enhanced transient responses and multilevel conductance states.

Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions

Small, EarlyView.
By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

Inhomogeneous chiral symmetry breaking in isospin-asymmetric strong-interaction matter

, 2017
In this thesis we investigate the effects of an isospin asymmetry on inhomogeneous chiral symmetry breaking phases, which are characterized by spatially modulated quark-antiquark condensates.

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Magnetically Decoupled Janus Bound States in the Continuum for Chirality–Topology Control

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
This article demonstrates the Janus BICs, which are bi‐layer photonic crystal (PhCs) structures composed of C3v and magneto‐optical C6v symmetry slabs. It offers a unique platform for independent controlling chirality and topological charge, which successfully realizes the decoupling of topological charge and chirality.

Luminescent Donor‐Acceptor Radical With Propeller Chirality: Bright and Photostable Red Circularly Polarized Luminescence and Whispering Gallery Mode Resonance

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
A series of donor‐attached brominated chiral luminescent radicals (CzTTBrM, 2CzTTBrM, and 3CzTTBrM) was synthesized, showing red to near‐infrared (NIR) circularly polarized luminescence (CPL) with exceptionally high PLQY of up to 76% and markedly enhanced CPL brightness (BCPL). Doping into polystyrene microspheres further yields whispering gallery mode

High‐Order Multipolar Excitations Governing Circular Dichroism in an All‐Dielectric Chiral Metasurface

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
An all‐dielectric asymmetric gammadion metasurface exhibits visible circular dichroism governed by helicity‐selective multipolar excitations. Quadrupole‐dominated and weaker mixed‐mode resonances are identified, and their distinct near‐field optical chirality and angular responses are revealed, establishing a direct link between structural asymmetry ...
