Clinicians often concurrently tackle critical challenges including emergency hemorrhage, secondary infection, and the elusive tracking of biodegradation of conventional hemostatic agents for complex wounds. Here, we report an intelligent hemostatic sponge (spCS@AIE) by incorporating aggregation‐induced emission (AIE) nanoparticles with short‐wave ...

Biomedical photoacoustic imaging [PDF]
Abstract Photoacoustic (PA) imaging, also called optoacoustic imaging, is a new biomedical imaging modality based on the use of laser-generated ultrasound that has emerged over the last decade. It is a hybrid modality, combining the high-contrast and spectroscopic-based specificity of optical imaging with the high spatial resolution ...

A dynamic state estimator for photoacoustic reconstruction
The photoacoustic (PA) effect is an emerging technique for characterizing the structural and compositional features of materials by combining light absorption with the generation of pressure waves. In practice, it is only possible to measure the pressure

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