Spatiospectral Photoacoustic Microscopy With Gain‐Switched Ti:Sapphire Laser for High‐Accuracy Molecular Dynamics Imaging

open access: yesLaser &Photonics Reviews, EarlyView.
Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.

Probabilistic estimation of reliable sensor spacing for wire break detection in prestressed concrete using acoustic emission technique

open access: yesStructural Concrete, EarlyView.
Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...

Wood‐Based Cellulose Nanocrystals as Reinforcement for Sustainable Concrete Composites

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 10, October 2026.
Wood‐derived cellulose nanocrystals (WCNCs) serve as sustainable nano‐reinforcements in normal‐strength concrete. Incorporation of an optimal WCNC dosage of 0.05 wt.% enhances the balance between workability and strength, resulting in significant increases in compressive strength (16.1%), splitting tensile strength (13.6%), and flexural load capacity ...
