Direct Imaging of Hydrogen‐Driven Dislocation and Strain Field Evolution in a Stainless Steel Grain

open access: yesAdvanced Materials, EarlyView.
Using in situ Bragg coherent X‐ray diffraction imaging, 3D nanoscale strain maps of a stainless steel grain were measured during hydrogen charging. Results show dislocation relaxation and climb, elucidating the role of point defects in hydrogen‐modified deformation behavior.

All‐Heat Control of Magnetization Dynamics on Van der Waals Magnets

open access: yesAdvanced Materials, EarlyView.
Heat dissipation in nanomagnetic devices mediated by femtosecond laser excitation constitutes one of the pressing challenges toward energy‐efficient information communication technologies. Here it is shown that heat and magnetization play together to determine the ultrafast spin dynamics of van der Waals magnets across any substrates and magnet ...

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent
