O grupo de desenvolvimento de jogos educacionais Ludo Educativo, projeto de extensão do Centro de Desenvolvimento de Materiais Funcionais (CDMF- CEPID – FAPESP), acaba de lançar o LabIncrível, um jogo no qual o aluno deve resolver […]
Highly Efficient and Magnetically Recoverable Niobium Nanocatalyst for the Multicomponent Biginelli Reaction Abstract: A new magnetically recoverable nanocatalyst was prepared by coating magnetite with niobium oxide (Fe3O4@Nb2O5) by using a simple wet impregnation method. The Fe3O4@Nb2O5 […]
Local electronic structure, optical bandgap and photoluminescence (PL) properties of Ba(Zr0.75Ti0.25) O-3 powders Abstract: Ba(Zr0.75Ti0.25)O3 (BZT-75/25) powders were synthesized by the polymeric precursor method. Samples were structurally characterized by X-ray diffraction (XRD), Rietveld refinement, X-ray absorption near-edge […]
Julio Sambrano, professor da Universidade Estadual Paulista – Júlio de Mesquita Filho (Unesp) campus Bauru, e Miguel San-Miguel, professor da Universidade Estadual de Campinas (Unicamp), foram conferencistas no 44ª Congreso Internacional de Químicos Teóricos de Expresión […]
A Prefeitura Municipal de São Carlos, através da Secretaria Municipal de Desenvolvimento Sustentável, Ciência e Tecnologia, levou a efeito na manhã do dia 10 de outubro a cerimônia de entrega do Prêmio Ciência e Tecnologia São […]
Spectroscopy and electronic structure of Sr2YRuO6 and Sr2YRu0.75Ir0.25O6 Abstract: We study the electronic structure of the Sr2YRuO6 and Sr2YRu0.75Ir0.25O6 compounds using x-ray (resonant) photoemission and absorption spectroscopies. The experimental results are interpreted with first-principles calculations, which […]
Pristine and Al-doped hematite printed films as photoanodes of p-type dye-sensitized solar cells Abstract: We hereby propose a non-expensive method for the deposition of pure and Al-doped hematite photoanodes in the configuration of thin films for […]
Raman signatures of monoclinic distortion in (Ba1-xSrx)(3)CaNb2O9 complex perovskites Abstract: Octahedral tilting is the most common distortion process observed in centrosymmetric perovskite compounds. Indeed, crucial physical properties of this oxide stem from the tilts of BO6 […]
Blue and red light photoluminescence emission at room temperature from CaTiO3 decorated with alpha-Ag2WO4 Abstract: CaTiO3 (CT) and α-Ag2WO4 (AW) semiconductors are widely known for their interesting electrical and photoluminescence (PL) properties. In this study, we decorated CT with AW for obtaining CaTiO3:α-Ag2WO4 (CT:AW), […]
