MultifunctionalHybrid Gels Containing Silver Nanoparticles,Gold Nanorods, and Protoporphyrin IX for Synergistic Photothermal–PhotodynamicTherapy

Abstract Photodynamic and photothermal therapies, enhanced by nanotechnology, show great potential in skin cancer treatment. This study reports the synthesis and characterization of hybrid sodium alginate gels conjugated with protoporphyrin-IX, associated with gold and silver nan...

Role of atmospheric sulfate from industrial gypsum emissions in shaping soil solution chemistry and aluminum speciation along the soil profile

, indicating vertical redistribution driven by water fluxes. PCA identified sulfate as the primary variable governing the organization of soil solution chemistry along the soil profile. Overall, these findings demonstrate that continuous atmospheric sulfate deposition from indust...
