Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals
Advanced Functional Materials, EarlyView.Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.

Generation of angular-momentum-dominated electron beams from a photoinjector
Physical Review Special Topics. Accelerators and Beams, 2004 Various projects under study require an angular-momentum-dominated electron beam generated by a photoinjector. Some of the proposals directly use the angular-momentum-dominated beams (e.g., electron cooling of heavy ions), while others require the beam ...

Downward Control from Lower Stratosphere? [PDF]
, 2005 The concept of downward control proposes a mechanism for the impact of the stratospheric circulation on the troposphere. Momentum forcing at upper-stratospheric levels induces a meridional circulation that eventually reaches the surface.

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe
Advanced Functional Materials, EarlyView.By systematically introducing defects into FeGe via ion‐beam modification, we demonstrate that disorder broadens the temperature regime over which the topological Hall effect ‐ a signature of skyrmions or other chiral textures — appears, while also increasing its magnitude.

Super-resolution orbital angular momentum holography
Nature Communications, 2023 The resolution of orbital angular momentum holography is limited by a fundamental sampling criterion. Here, the authors break the resolution barrier by temporal multiplexing of binary holograms and enhance the resolution and capacity by several times.

Exchange‐Coupled Two‐Dimensional MOFs
Advanced Functional Materials, EarlyView.Graphene mediates ferromagnetic coupling between two‐dimensional metal‐organic frameworks and cobalt. Fe‐tetracyanobenzene develops a remanent magnetic response whose orientation follows the cobalt magnetization direction and persists up to room temperature, whereas Ni‐TCNB remains only field‐polarized.

Advanced Functional Materials, EarlyView.Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...
