Thermal decomposition of solid state compounds of lanthanide and yttrium benzoates in CO2 atmosphere

, 2008
Solid-state Ln-Bz compounds, where Ln stands for trivalent lanthanides and Bz is benzoate have been synthesized. Simultaneous thermogravimetric and differential thermal analysis in a CO2atmosphere were used to study the thermal decomposition of these ...

Characterization and corrosion study of the Dispersalloy dental amalgam by impedance techniques and anodic polarization

, 1997
The corrosion of dental amalgam in aqueous media was interpreted by means of a.c. impedance techniques and anodic polarization. The Nyquist and Bode diagrams are influenced by the porous structure of the amalgams, the surface film formation and the ...

Plasma–Kinetic Coupling and Redox Mechanisms in the Degradation of Acid Red 51 by Atmospheric Corona Discharge

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the degradation of the xanthene dye Acid Red 51 (ARE‐51) using atmospheric‐pressure corona discharge plasma, integrating electrical characterization, optical emission spectroscopy (OES), kinetic modeling, and physicochemical analysis to establish a unified plasma–liquid interaction framework. A degradation efficiency of
