Nature‐Inspired Functional Aerogel Fibers with Engineerable Core–Shell Morphology

open access: yesAdvanced Materials Technologies, EarlyView.
Nature‐inspired core–shell aerogel fibers are fabricated through coaxial wet‐spinning, which combines a polyimide shell with MXene core. The fibers exhibited absorption‐dominant EMI shielding, low thermal conductivity, and mechanical robustness, demonstrating multifunctional potential for wearable electronics and advanced smart textiles.

Particle Size Matters – Impact of Particle Size and Crucible Geometry on Sublimation Behavior of Formamidinium Iodide

open access: yesAdvanced Materials Technologies, EarlyView.
FAI precursor particle size and sublimation crucible geometry critically determine vapor flux directionality and deposition uniformity in thermal sublimation processes. Conical crucibles exhibit particle‐size‐dependent beam focusing, while cylindrical crucibles show a much more homogeneous deposition due to de‐focusing effects of the emitted vapor flux.

Size Effect on Photothermal Heating Ability of Gold Bipyramids

open access: yesAdvanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces

open access: yesAdvanced Optical Materials, EarlyView.
Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.
