Photothermally Powered 3D Microgels Mechanically Regulate Mesenchymal Stem Cells Under Anisotropic Force

open access: yesAdvanced Materials, EarlyView.
The photothermally powered microgel is designed to mechanically train mesenchymal stem cells using spatially patterned exogenous forces in three‐dimensional (3D) workspaces. When microgels are activated selectively via photothermal actuation, locally confined tens of nN forces are exerted on cells, triggering osteogenic differentiation in encapsulated ...

Colossal Cryogenic Electro‐Optic Response Through Metastability in Strained BaTiO3 Thin Films

open access: yesAdvanced Materials, EarlyView.
Utilizing the thermodynamic theory of optical properties, a colossal cryogenic electro‐optic response in BaTiO3 thin films is designed and demonstrated by stabilizing a low symmetry metastable monoclinic phase via epitaxial strain tuning with an electro‐optic response reaching ≈2516 pm V−1 at 5 K. This approach represents a new paradigm for engineering

Inverted PAINT for Material‐Specific Super‐Resolution Fluorescence Imaging of Semiconductors

open access: yesAdvanced Materials, EarlyView.
This study presents Inverted PAINT, a label‐free super‐resolution fluorescence imaging method optimized for thick and non‐transparent semiconductor materials. By employing electrostatic dye–surface interactions in an inverted geometry, the technique enables material‐specific, multicolor, and 3D nanoscale imaging, with applications in semiconductor ...

Additively Manufacturable High‐Strength Aluminum Alloys with Coarsening‐Resistant Microstructures Achieved via Rapid Solidification

open access: yesAdvanced Materials, EarlyView.
Rapid solidification in laser additive manufacturing facilitates the precipitation of metastable phases in aluminum alloys. These metastable phases significantly enhance the strength by forming a high‐volume fraction of precipitates with an order of magnitude reduced sizes and smaller interspacing, effectively impeding dislocation motion. Consequestly,
