Broadband and Enhanced Second‐Harmonic Generation in Metallic 3R‐TaS2

Small, EarlyView.
A pronounced and robust SHG response has been observed in metallic 3R‐TaS2. It shows broadband SH conversion from 1020 nm to 1410 nm. Moreover, compared to the sapphire substrate, 3R‐TaS2 flakes with various thicknesses on the gold substrate showed different SHG enhancement; the enhancement factors range from 2.7 to 45.5.

Two‐Photon Endomicroscopy for Image‐Guided Magnetic Micro‐Agents

Small, EarlyView.
Image‐guided manipulation of magnetic micro‐agents requires localized fluorescence feedback capable of resolving dynamic interactions in confined environments. This study introduces a two‐photon endomicroscopy platform for real‐time motion tracking, multicolor micro‐agent discrimination, and imaging through biological tissue.

From Simplicity to Complexity: Substituent‐Controlled Z′ Multiplicity as a Design Principle for Thermally Robust Yet Programmable Anisotropic Expansion

Small, EarlyView.
Leveraging substituent‐controlled packing competition in 2,6‐bis(4‐tert‐butylphenyl)anthracene, we developed a high‐Z′ symmetry‐amplification strategy that controls crystallographic inequivalence. This strategy enables reversible, thermally robust phase transitions and programmable anisotropic thermal expansion within a single molecular crystal ...

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

VIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...
