Renata C. Lima,Leilane R. Macario,J. W. M. Espinosa,Valeria M. Longo,R. Erlo,N. L. Marana,Julio R. Sambrano,M. L. dos Santos,Ana Paula de Moura,Paulo S. Pizani,Juan Andrés,Elson Longo,José Arana Varela +12 more
TL;DR: The theoretical results indicate that the key factor controlling the electronic behavior can be associated with a symmetry breaking process, creating localized electronic levels above the valence band.
Urea-based synthesis of zinc oxide nanostructures at low temperature
Juliane Z. Marinho,Fernanda C. Romeiro,Samantha C.S. Lemos,Fabiana V. Motta,Carla dos Santos Riccardi,Máximo Siu Li,Elson Longo,Renata C. Lima +7 more
TL;DR: In this article, the preparation of nanometer-sized structures of zinc oxide (ZnO) from zinc acetate and urea as raw materials was performed using conventional water bath heating and a microwave hydrothermal (MH) method in an aqueous solution.
rGO-ZnO nanocomposites for high electrocatalytic effect on water oxidation obtained by microwave-hydrothermal method
Fernanda C. Romeiro,Mônica A. Rodrigues,Luiz A. J. Silva,Ariadne C. Catto,Luís F. da Silva,Elson Longo,Edson Nossol,Renata C. Lima +7 more
TL;DR: In this paper, a reduced graphene oxide-zinc oxide (rGO-ZnO) nanocomposites were synthesized using a facile microwave-hydrothermal method under mild conditions, and their electrocatalytic properties towards O 2 evolution were investigated.

Rapid preparation of α-FeOOH and α-Fe2O3 nanostructures by microwave heating and their application in electrochemical sensors
Juliane Z. Marinho,Rodrigo H. O. Montes,A. P. de Moura,Elson Longo,José Arana Varela,Rodrigo A.A. Munoz,Renata C. Lima +6 more
TL;DR: The use of microwave heating allowed iron oxides to be prepared with shorter reaction times when compared to other synthesis methods α-FeOOH nanoplates were incorporated into graphite-composite electrodes, which presented electrocatalytic properties towards the electrochemical oxidation of ascorbic acid in comparison with unmodified electrodes as discussed by the authors.

Influence of Al2O3 nanoparticles structure immobilized upon glassy-carbon electrode on the electrocatalytic oxidation of phenolic compounds
Ana P. Lima,Roberta C. Souza,Murilo N.T. Silva,R. F. Gonçalves,Edson Nossol,Eduardo M. Richter,Renata C. Lima,Rodrigo A.A. Munoz +7 more
TL;DR: In this article, a glassy-carbon electrode (GCE) surface modified with alumina nanoparticles of different structures and morphologies was verified for electrocatalytic oxidation of catechol (CT), dopamine (DP) and tert-butylhydroquinone (TBHQ).
