Revealing the Resonant Physics of Open Photonic Time Crystals

Laser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics

Macromolecular Rapid Communications, EarlyView.
Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

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

Peptide‐Ligand Cooperative Interplay Drives Gold Nanoparticle Encapsulation by Protein Cages

Small, EarlyView.
Gold nanoparticle encapsulation within protein cages is governed by salt‐dependent binding energetics and cooperative peptide–ligand interactions. Ligands enhance electrostatic attraction while peptides extend recruitment and prevent kinetic trapping, enabling robust cargo loading. This molecular‐level insight links experiments and simulations, guiding

High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

Small, EarlyView.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

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.
