Bridging Chemical Literature and Molecular Graphs: LLM‐Augmented Enantioselectivity Prediction for Iridium‐Catalyzed Asymmetric C–H Borylation

Advanced Science, EarlyView.
A machine‐learning framework for asymmetric C–H borylation bridges multi‐entity 3D molecular graphs and chemical literature. Atom‐resolved mechanistic annotations extracted by large language models augment three‐component graph encoding of catalyst, substrate, and product. The model predicts enantioselectivity with high accuracy on unseen scaffolds and

Interfacial Asymmetry and Surface Roughness Enhanced Topological‐Hall‐Like Transport in SRO/BTO/SRO Trilayers

Advanced Science, EarlyView.
Trilayer oxide architecture introduces interfacial asymmetry and surface roughness in SRO/BTO/SRO heterostructures, creating a locally modulated polar and magnetic landscape. This design enhances the topological‐Hall‐like response, achieving a broad 5–90 K stability window and a maximum ρTHE of 0.8 µΩ cm, demonstrating an effective route to amplify ...

Cr1/4NbSe2‐Single Crystal Growth and Evolution of Antiferromagnetic Correlated States

Advanced Science, EarlyView.
High‐quality single crystals Cr1/4NbSe2 were synthesized and comprehensively characterized for the first time. Advanced structural, electronic, and magnetic measurements uncover a correlated antiferromagnetic state, resolving longstanding inconsistencies regarding magnetic behavior derived from earlier polycrystal studies.

Layered chiral metallic meta-materials

, 2002
Using electron beam lithographic techniques we have manufactured left and right-handed forms of an artificial medium consisting of high densities of microscopic planar chiral metallic objects distributed regularly in a plane. In this artificial medium we

Intrinsic i$i$‐Wave Altermagnetism in 2D Graphene Superlattices

Advanced Science, EarlyView.
Altermagnetism has so far been mostly proposed in transition metals compounds. Here we show that monolayer and bilayer graphene antidot superlattices realize a carbon‐based i‐wave altermagnet. This is demonstrated with a combination of symmetry analysis, first principles methods and effective models, featuring a six‐fold spin splitting texture in ...
