Nitrogen‐Vacancy Magnetometry of Edge Magnetism in WS2 Flakes
Advanced Functional Materials, EarlyView.Using nitrogen‐vacancy magnetometry, the authors visualize room‐temperature stray magnetic fields localized at the edges of WS2 flakes. Their measurements reveal edge‐specific magnetization consistent with spin canting in antiferromagnetically coupled edge states.

Salt‐Compact Albumin as a New Pure Protein‐based Biomaterials: From Design to In Vivo Studies
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.A new class of materials built entirely of native albumin protein is designed using a simple protocol based on salt‐assisted compaction, breaking with current crosslinking strategies. This green process leads, surprisingly, to water‐insoluble handable materials with high preservation of their native protein structures and Young's modulus close to that ...
