Abstract: Modulating and elevating the PL intensity of inorganic semiconductor through the co-doping of rare-earth and alkali cations is a viable approach for regulating their behavior. Here, we present a dual strategy, based on the co-doping process of Eu3+/Li+ of […]
Abstract: In this work, pure SnO2 nanoparticles (SnO2 NPs), doped and co-doped with Co2 + and Nb5+ (0.05 and 0.1 mol), were prepared using babassu mesocarp (Orbgnya Speciosa) extract as a natural polymerizing agent and microwave-assisted hydrothermal treatment. X-ray diffraction analysis (XRD) showed that the crystallinity of […]
Abstract: Under electron irradiation, transition metal molybdates can form transition metal nanostructures, enabling chemical reactions and physical processes. Understanding the driving force of this transformation is crucial for various applications. Herein, we investigate the structural […]
Abstract: The semiconductor copper tungstate (CuWO4) may end up in aquatic ecosystems since it has the potential for water decontamination. The toxic effects of CuWO4 are totally unknown for eukaryotic organisms. In view of this, we […]
Abstract: In this work, catalysts based on composite films composed by chitosan with disordered NiWO4 (10, 20, and 40 % w/w) were synthesized for their application in the oxidation of sulfides to sulfones. The catalysts were characterized by X-ray diffraction (XRD), Fourier-transform […]
Abstract: Solid solutions, formed by combining two transition metal oxides with distinct properties, offer promising potential for optimizing functional characteristics that may be lacking in the parent materials. In this study, NiWO4 and NiMoO4 semiconductors […]
L Cabral, Elson Longo, Miguel A San-Miguel, Edson Leite, EZ da Silva, Juan Andrés Abstract: Laser irradiation (LI)–matter interaction provides a versatile means to manipulate the physicochemical properties of materials. Understanding material responses to LI […]
Abstract: Ecotoxicological studies involving microplastics (MPs) conducted on a laboratory scale may not always accurately mirror real environmental conditions (types, sizes, shapes, and concentrations of MPs). This review primarily focused on examining studies that investigated […]
Giovanna Grasser, aluna de mestrado do CDMF, foi premiada com o Best Oral Prize por sua melhor apresentação oral estudantil durante o XXIII B-MRS Meeting (SBPMat 2025), realizado de 28 de setembro a 2 de […]
Abstract: The physical and chemical properties of metal oxides are closely related to their surface termination, the presence of defects, and structural disorder, making the assignment of surface-morphology-property relationship difficult. The identification of specific descriptors […]
