Correlation between structural evolution and oxidative desulfurization activity for magnetically-recoverable γ-Fe2O3@SiO2 core-shell–Supported WOx nanostructure

Autor: Diógenes H. Piva, Roger H. Piva, Monize Picinini, Ariano D. Rodrigues, Ernesto A. Urquieta-González

Publikováno v: Catalysis Communications, Vol 148, Iss , Pp 106182- (2021)

In this work, the effect of calcination temperature on the preparation of WOx catalysts supported on γ-Fe2O3@SiO2 core-shell nanostructure is reported. Powder XRD and Raman results evidenced that during calcination between 400 and 600°C, the SiO2 s

Acidic Dressing Based on Agarose/Cs

Autor: Roger H, Piva, Marina C, Rocha, Diógenes H, Piva, Hidetake, Imasato, Iran, Malavazi, Ubirajara P, Rodrigues-Filho

Publikováno v: ACS applied materialsinterfaces. 10(37)

Regulation of wound pH from alkaline to acidic is a simple and powerful approach to reduce wound microbial colonization and infection. Here, we present a nanocomposite material possessing intrinsic acidic surface pH as an innovative antimicrobial wou

BICUVOX.1-matrix composite electrolyte with yttria-stabilized zirconia as an inert phase: SEM evaluation of the chemical stability under hydrogen atmosphere

Autor: R H, Piva, D H, Piva, J, Venturini, R, Floriano, M R, Morelli

Publikováno v: Scanning. 37(5)

The purpose of this study is to evaluate the efficacy of yttria-stabilized zirconia (3Y-TZP) as an inert phase to prevent the decomposition of Bi2 V0.9 Cu0.1 O5.5 -δ (BICUVOX.1) electrolyte under reducing atmosphere. A post-mortem scanning electron
