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

Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

Small, EarlyView.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

Template‐Assisted 3D‐PVDF Nanonetworks for Passive Daytime Radiative Cooling

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Three‐dimensional polyvinylidene fluoride (3D‐PVDF) nanostructures were fabricated by infiltrating the polymer into 3D anodic aluminum oxide (3D‐AAO) templates. Due to their high solar reflectance (82.4%) and infrared emissivity (96.7% between 8 and 13 µm), they are an ideal candidate for radiative cooling.

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).
