Au-sensitised TiO<inf>2</inf> and ZnO nanoparticles for broadband pharmaceutica...
Zheng, Fangyuan; Queirós, Joana M.; Martins, Pedro M.; Fernández de Luis, Roberto; Fidalgo-Marijuan, Arkaitz; Vilas-Vilela, José L.; Lanceros-Mendez, S.A large number of contaminants of emerging concerns, such as most pharmaceuticals, exhibit high persistency in water bodies due to the difficulty of their removal by conventional treatment methods, causing severe environmental issues. Semiconductor-based photocatalysis has become an exciting solution to remove these pollutants through photocatalytic degradation. However, the high diversity of chemical compositi...
Hybrid TiO2:Au nanostars based polymeric membranes for photocatalytic degradati...
Zheng, Fangyuan; Martins, Pedro M.; Queirós, Joana M.; Tavares, Carlos J.; Vilas-Vilela, José Luis; Lanceros-Mendez, S.; Reguera, JavierAntibiotics represent one increasingly harmful type of contaminant of emerging concern in treated and non-treated water. They cause the generation of antibiotic-multiresistant organisms, one of the major challenges in current medicine. Plasmonic-photocatalysis using solar energy represents a promising solution for their removal with low energy consumption. Its successful application requires the improvement of ...
Size effect in hybrid TiO2:Au nanostars for photocatalytic water remediation ap...
Zheng, Fangyuan; Martins, Pedro Manuel Abreu; Queirós, Joana M.; Tavares, Carlos J.; Vilas-Vilela, José Luis; Lanceros-Méndez, S.; Reguera, JavierTiO<sub>2</sub>:Au-based photocatalysis represents a promising alternative to remove contaminants of emerging concern (CECs) from wastewater under sunlight irradiation. However, spherical Au nanoparticles, generally used to sensitize TiO<sub>2</sub>, still limit the photocatalytic spectral band to the 520 nm region, neglecting a high part of sun radiation. Here, a ligand-free synthesis of TiO<sub>2</sub>:Au nan...
Ionic liquid-based materials for biomedical applications
Correia, Daniela Maria; Fernandes, Liliana Correia; Fernandes, Margarida; Hermenegildo, Bruno; Meira, Rafaela; Ribeiro, Clarisse; Ribeiro, SylvieIonic liquids (ILs) have been extensively explored and implemented in different areas, ranging from sensors and actuators to the biomedical field. The increasing attention devoted to ILs centers on their unique properties and possible combination of different cations and anions, allowing the development of materials with specific functionalities and requirements for applications. Particularly for biomedical app...
