Journal ArticleDOI
Development of metal oxide nanoparticles with high stability against particle growth using a metastable solid solution
Edson R. Leite,Adeilton Pereira Maciel,Ingrid Távora Weber,Paulo Noronha Lisboa-Filho,Elson Longo,Carlos O. Paiva-Santos,André Vitor Chaves de Andrade,C. A. Pakoscimas,Y. Maniette,Wido H. Schreiner +9 more
Journal ArticleDOI
Structural and electrochemical properties of LiCoO2 prepared by combustion synthesis
TL;DR: In this article, a small amount of the LiCoO2 phase was obtained directly from the combustion reaction, however, a heat treatment was necessary for the phase crystallization, performed at the temperature range from 400 up to 700 °C for 12 h.
Journal ArticleDOI
The thermoelastic bending and thermal diffusion processes influence on photoacoustic signal generation using open photoacoustic cell technique
Aloisi Somer,F. Camilotti,G. F. Costa,Cláudia Bonardi,Andressa Novatski,André Vitor Chaves de Andrade,V. A. Kozlowski,Gerson Kniphoff da Cruz +7 more
TL;DR: In this paper, the authors explore the potential use of the OPC technique to study the effectiveness of thermoelastic bending process and thermal diffusion process on photoacoustic signal (S) generation in solids.
Journal ArticleDOI
Synthesis, characterization and chemoprotective activity of polyoxovanadates against DNA alkylation.
Giovana G. Nunes,Ana C. Bonatto,Carla G. de Albuquerque,Andersson Barison,Ronny R. Ribeiro,Davi F. Back,André Vitor Chaves de Andrade,Eduardo L. de Sá,Fábio O. Pedrosa,Jaísa F. Soares,Emanuel Maltempi de Souza +10 more
TL;DR: The direct reaction of B with increasing amounts of DMS in both buffered and non-buffered aqueous solutions revealed the sequential formation of severalVanadium(IV), vanadium(V) and mixed-valence aggregates of different nuclearities, whose relevance to the DNA-protecting activity is discussed.
Journal ArticleDOI
Synthesis and characterization of Fe3+ doped cerium–praseodymium oxide pigments
Renata Cristina Olegário,Eder Carlos Ferreira de Souza,José Flávio Marcelino Borges,João Batista Marimon da Cunha,André Vitor Chaves de Andrade,Sandra Regina Masetto Antunes,Augusto Celso Antunes +6 more
TL;DR: Inorganic pigments based on (0.95− x )CeO 2.(0.05)Pr 6 O 11.( x )α-Fe 2 O 3 ( x ǫ = 0.00; 0.01; 0., 0.02, 0.03 and 0.04) were synthesized by the solid state reaction method at 1300°C for 3h, and the modified sol-gel method at 900°C at 3h for 3H as discussed by the authors.
