Observation of Linear and Nonlinear Light Trapping on Topological Dislocations
Laser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Beyond Cocrystals: Hierarchical Functional Assemblies via Noncovalent Synthesis
Advanced Science, Volume 13, Issue 13, 3 March 2026.Non‐covalent interactions (NCIs) drive the formation of organic cocrystals with diverse structures and tunable optoelectronic properties. This review explores the essential factors governing these properties, highlighting how the sequential nucleation of cocrystals leads to the self‐assembly of organic hierarchical structures (OHSs).
