Two‐Photon Fluorescence and Second‐Harmonic Generation Microscopy: Principles and Biomedical Applications

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Ultrastable Water‐in‐Water Emulsions by Addition of Polyion Complex Micelles

Macromolecular Rapid Communications, Volume 47, Issue 19, 6 October 2026.
Water‐in‐water emulsions from mixtures of dextran and poly(ethylene oxide) (PEO) prepared in the presence of polyion complex micelles display an increase of stability from few hours to several months. Both dextran‐in‐PEO and PEO‐in‐dextran were stable against coalescence over this period of time.

Spiropyran‐Crosslinked PDMS Optical Waveguides for Pressure Sensing and Visual Cue of Localized Pressure Threshold

Polymers for Advanced Technologies, Volume 37, Issue 10, October 2026.
ABSTRACT Compliant optical waveguides are promising candidates for stress/strain sensing in soft robotics and personalized healthcare. While poly(dimethylsiloxane) (PDMS) offers a robust platform, enhancing sensitivity and integrating localized visual indicators for pressure threshold detection remains an active area of research.

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like
