Unlocking Multimodal Nonlinear Microscopy for Deep‐Tissue Imaging under Continuous‐Wave Excitation with Tunable Upconverting Nanoparticles

Advanced Materials, EarlyView.
This study introduces a multimodal nonlinear microscopy approach using upconverting nanoparticles (UCNPs) under continuous‐wave excitation. The UCNPs exhibit high‐order nonlinear optical responses, enabling deep‐tissue 3D imaging, video‐rate wide‐field imaging, and depth‐selective photomodulation.

Unveiling the Aging Effect at the Interface of N719 Dye‐Sensitized Solar Cells

Advanced Materials Interfaces, EarlyView.
Iodide is incorporated into the N719 layer through two mechanisms: the known ligand exchange of NCS with I and a second yet unknown mechanism which significantly blocks the charge regeneration process of the N719 dye contributing to the cell degradation.
