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

Metamaterials: electromagnetic enhancement at zero-index transition

, 2008
Resonant enhancement of electromagnetic waves propagating at oblique incidence in metamaterials, with dielectric permittivity and magnetic permeability linearly changing from positive to negative values, has been predicted and theoretically studied. This

Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.

Infrared‐Microwave Compatible Stealth Transparent Metasurface With Digital Camouflage and Hybrid Absorption‐Scattering

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Traditional metasurfaces suffer from the drawbacks of pure microwave absorption and low IR emissivity stealth, namely failing to match complex ambient backgrounds with varying IR emissivity and generating excess heat accumulation (enhanced IR thermal radiation).

Single‐Photon Emission From TMDCs through Strong Coupling to EQ Plasmon Modes of an Au Metasurface

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Compact, deterministic solid‐state single‐photon sources that operate at room temperature and integrate with planar nanophotonics are essential for the development of scalable quantum photonic technologies. This work presents a TMDC monolayer strongly coupled to a gold (Au) metasurface featuring an electric quadrupole mode, enabling high‐purity single ...

Tunable Plasmon‐Enhanced Wide‐Angle Terahertz Perfect Absorption via Lorentz Media

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
A planar graphene‐Lorentz‐DBR structure realizes wide‐angle terahertz perfect absorption through a composite phase‐amplitude matching mechanism. The Lorentz dielectric provides dispersive phase compensation and controlled loss, whereas graphene supports dissipative coupling, enabling high absorption up to 80° incidence and multichannel spectral ...

Chiral Light–Matter Interaction for Controlling Nanoplasmonic Fields

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
This paper demonstrates plasmonic circular dichroism using gold nanoparticle dimers that exhibit high near‐field contrast under left‐ and right‐circularly polarized illumination. SNOM mapping reveals that the dichroic behavior of the dimers transforms hot spots into cold spots with full optical control. Additionally, the eigenmode excitations and their

Nanoscale Mapping of Plasmonic Charge Transport in Nano‐Resonators Based on Resistive Switching Materials

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.
