Manganese oxide coated TiO2 nanotube-based electrode for efficient and selective electrocatalytic sulfide oxidation to colloidal sulfur [PDF]

open access: yesJournal of Applied Catalysis B: Environmental, 120383, 2021, 2021
Manganese oxide-coated TiO2 nanotube array (NTA) was synthesized and applied for the (electro)catalytic oxidation of sulfide. By setting the electrodeposition parameters and calcination temperature, the coating obtained was MnO2 or Mn2O3, with rod or needle like morphology. Excellent catalytic activity of the Ti/TiO2 NTA/MnxOy anodes resulted in robust

Effects of point defects on oxidation of 3C-SiC [PDF]

open access: yes, 2021
The influence of implantation-induced point defects (PDs) on SiC oxidation is investigated via molecular dynamics simulations. PDs generally increase the oxidation rate of crystalline grains. Particularly, accelerations caused by Si antisites and vacancies are comparable, and followed by Si interstitials, which are higher than those by C antisites and ...

Galvanic Sensor for Detecting Corrosion during Acid Cleaning of Magnetite in Steam Boilers

open access: yesMetals, 2021
A simple galvanic sensor was developed to determine the onset of iron corrosion under conditions similar to those used for removing the iron oxide (magnetite) layer from steam boilers with a hy-drochloric acid solution.

Effect of Vanadium Thickness and Deposition Temperature on VO2 Synthesis using Atmospheric Pressure Thermal Oxidation [PDF]

open access: yesThin Solid Films 724, 138630 (2021), 2021
Vanadium dioxide (VO2) is a phase transition material that undergoes a reversible insulator-metal phase transition at ~ 68 C. Atmospheric pressure thermal oxidation (APTO) of vanadium (V) is a simple VO2 synthesis method in which V thin film is oxidized in open air.
