Room‐Temperature Alane Dehydrogenation for Visible‐Light‐Driven Photocatalytic Hydrogen Supply System

open access: yesAdvanced Science, EarlyView.
In situ formed Al/MOF enables viable visible‐light‐driven photocatalytic dehydrogenation of alane (AlH3) confirming practical application. Results demonstrate that Al nanoparticles prolong lifetime of photogenerated charge carriers via localized surface plasmon resonance induced hot electron injection, while AlH3 chemisorption triggers interfacial ...

Cross‐Platform Biosensing of Immune Receptors Using Peptide‐Functionalized Graphene

open access: yesAdvanced Science, EarlyView.
A peptide‐functionalized graphene biosensor enables sensitive and selective detection of living immune cells. Targeting Formyl‐Peptide Receptor 2 (FPR2), the assay is demonstrated on model cells and primary human neutrophils. The same assay is applied to two complementary platforms: graphene‐enhanced surface plasmon resonance for optical benchmarking ...

Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

open access: yesAdvanced Science, EarlyView.
This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
