Empirical mathematical model for absorption and evaporation phenomena of organic solvent in electrically-sensitive wood
Wood, an anisotropic and hygroscopic material, is often exposed to organic solvents as well as moisture, accompanying absorption and evaporation phenomena. Although different dynamics are expected at the uptak...

Thermal regeneration characteristics of titanium isopropoxide-modified TiO2 for the removal of environmentally hazardous NOx in iron ore sintering process
The deactivation and thermal regeneration characteristics of a V2O5-WO3/TiO2 catalyst modified with titanium isopropoxide (TTIP) were investigated after it was applied for 2,400 h at 240 °C in a selective catalyt...

Local structural change and catalytic activity of Zr-doped amorphous CeTiOx for the low-temperature selective catalytic reduction of NO with NH3
Ce–Ti oxide catalysts were synthesized using Zr do** to form fully amorphous catalysts. The Ce0.3Ti0.7O2 catalyst had fine crystalline grain on the surface of the catalyst powders throughout the particles, wher...

Reduced graphene oxide supported V2O5-WO3-TiO2 catalysts for selective catalytic reduction of NOx
We present a reduced-graphene-oxide (rGO)-supported V2O5-WO3-TiO2 (VWTi) catalysts for the efficient selective catalytic reduction of NOx. The rGO support provides well-dispersed functional sites for the nucleati...
