The aim of this work is to measure the effect band-gap on TiO2 thin films by changing tetrabutylorthotitanate (TBOT), diethanolamine (DEA), and temperature. sol-gel method experimentally introduced find out better varying concentration TBOT (4 ml 10 ml), DEA (2 5 temperature (350°C 650°C). With help an ultraviolet-visible spectrophotometer for wavelength 300-900 nm, these are characterized conc...

In this work, the absorption–desorption performance of CO2 in six new solvent blends amine (diisopropylamine (DPA), 2-amino-2-methyl-1-propanol (AMP), methyldiethanolamine (MDEA), diethanolamine (DEA), diisopropanolamine (DIPA), and ethanolamine (MEA)), sulfolane, methanol has been monitored using ATR-FTIR spectroscopy. Additionally, NMR-based species confirmation viscosity analysis were done f...

Nano- and micro-sized ZnO spheres were fabricated via a simple solvothermal synthesis using two different precursors, while diethanolamine was used to control the morphology. The applied solvent composition, precursor ratio treatment temperature mathematically correlated with diameter of spheres. crystallite size could be easily controlled by adjusting temperature, providing flexibility during ...

Emulsion liquid membrane (ELM) has been widely studied as an alternative method for amine absorption technology in the removal of acid gases such carbon dioxide (CO2) and hydrogen sulphide (H2S). However, searching stable ELM formulation with enhanced CO2 remains challenge. Therefore, this study, aqueous solution containing a mixture methyl diethanolamine (MDEA) 2-amino-2-methyl-1-propanol (AMP...
