Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Monolithic UV‐Laser Programming of Photothermally Meta‐Morphing SMA Structures: Dual‐Encoded Kirigami Mechanics and Photonic Absorbance

Advanced Science, EarlyView.
A monolithic manufacturing strategy is presented for photothermal shape memory alloy (SMA) meta‐morphing structures. Using a single‐step UV‐laser process, the mechanical compliance is programmed via kirigami patterning while optical absorbance is simultaneously tuned through surface oxidation.

Nanocurvature‐Activated Dipolar Polarization in M–N4 Single‐Atom Sites for High‐Performance Electromagnetic Wave Absorption

Advanced Science, EarlyView.
Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.

Mass‐Transport–Engineered CCM Architecture Employing MPL‐Free Carbon Paper and Graphene‐Coated Ni Foam Channels for High‐Temperature PEM Fuel Cells

Advanced Science, EarlyView.
A CCM‐based architectural strategy is introduced for high‐temperature PEM fuel cells, enabling MPL‐free carbon paper gas diffusion layers via decal‐transfer processing. By co‐engineering the CCM, GDL, and a G‐foam flow field, oxygen transport is enhanced while phosphoric‐acid leakage is suppressed, resulting in high power density and stable operation ...
