Spatiotemporally Resolved Light Propagation in Transparent Wood

open access: yesAdvanced Optical Materials, EarlyView.
Light propagation mechanism changes from diffusive regime in native, white and delignified wood to near ballistic in transparent wood. Abstract Transparent wood biocomposite (TW) is a sustainable optical material that combines high transmittance with mechanical strength but also exhibits pronounced haze. This haze limits applications where high optical

Linker‐Free Covalent DNA Functionalization of Quantum‐Grade Nanodiamonds

open access: yesAdvanced Optical Materials, EarlyView.
Nanodiamond (ND) surface is terminated with azide groups via nucleophilic substitution and decarboxylative azidation. The resulting azidated NDs display high click reactivity while retaining the spin and charge properties of nitrogen‐vacancy centers.

Multimodal Luminescence from LaAlO3:Eu3+ via Trap Modulation for High‐Temperature Applications

open access: yesAdvanced Photonics Research, EarlyView.
LaAlO3:Eu3+ (LAO:E) phosphor exhibiting multimode luminescence enabled by multilevel traps spanning shallow to deep states is reported. These traps ensure controlled charge storage and release at room and elevated temperatures. Experimental studies and theoretical calculations reveal the trapping–detrapping mechanism, highlighting LAO:E as a promising ...

Ultrathin Graphene Strain Sensor Arrays for High‐Sensitivity Multifunctional Sensing with Millimeter‐Scale Resolution

open access: yesAdvanced Sensor Research, EarlyView.
This study reports an ultrathin graphene‐based strain sensor array fabricated on a 5 µm polyimide substrate. The array achieves millimeter‐scale spatial resolution (≈70 devices cm−2), high sensitivity with a gauge factor of 144, and reliable durability over 5000 cycles.

Ni Single Atoms in Zeolite Beta for Selective Alkyne Hydrogenation

open access: yesAdvanced Sustainable Systems, EarlyView.
Single‐atom Ni in zeolite Beta (Ni1/BEA) selectively remove trace acetylene from ethylene. Ni1/BEA achieve full conversion with ≈89% ethylene selectivity, stable for 24 h without coking, and 12 times higher TOF than prior zeolite‐supported single‐atom Ni catalysts. Na+ exchange suppress Brønsted acid‐catalyzed oligomerization. Under ethylene‐rich feeds,
