Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

Photoacoustic Spectroscopy Using a Synchrotron Light Source [PDF]

, 2001
We have investigated the use of a synchrotron as a source for infrared photoacoustic spectroscopy. A synchrotron has an intrinsically high radiance, which is beneficial when photoacoustic spectroscopy is applied to small samples, especially at long ...

A Reversible Clearing Strategy Enables Robust Label‐Free Phase Imaging of Thick Tissues

Laser &Photonics Reviews, EarlyView.
The principle of a reversible clearing strategy via glycerol and tartrazine solution (GTS) for robust whole‐slide label‐free phase imaging of thick tissue slices via high‐throughput Fourier ptychographic microscopy (FPM) and lensless digital holographic microscopy (LDHM). ABSTRACT Thick biological specimens impose strong scattering and attenuation that

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

Laser &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.
