A facile energy-efficient approach to prepare super oil-sorbent thin films
( Elsevier Ltd , 2023 , Article)Oil spills on water surface and shoreline have caused significant water pollution, and one of the ways to deal with them is to use oil sorbents. An effective sorbent provides high oil uptake and retention values, high ... -
Highly selective gas sensors from photo-activated ZnO/PANI thin films synthesized by mSILAR
( Elsevier Ltd , 2017 , Article)Zinc oxide (ZnO) nano-polycrystalline thin films has been prepared by cost-effective microwave assisted successive ionic layer adsorption and reaction (mSILAR) technique. ZnO/PANI prepared by in situ polymerization technique ... -
Key applications and potential limitations of ionic liquid membranes in the gas separation process of CO2, CH4, N2, H2 or mixtures of these gases from various gas streams
( MDPI AG , 2020 , Article Review)Heightened levels of carbon dioxide (CO2) and other greenhouse gases (GHGs) have prompted research into techniques for their capture and separation, including membrane separation, chemical looping, and cryogenic distillation. ... -
Synthesis of nanostructured novel ion-imprinted polymer for selective removal of Cu2+ and Sr2+ ions from reverse osmosis concentrated brine
( Elsevier , 2023 , Article)This study aims to prepare an ion-imprinted polymer (IIP) using copper sulfate as a template and potassium persulfate as an initiator to selectively adsorb copper ions (Cu2+) from aqueous solutions and in an attempt to ... -
Thermodynamics and kinetics of CH4/CO2 binary mixture separation by metal-organic frameworks from isotope exchange and adsorption break-through
( Elsevier B.V. , 2018 , Article)We combine the isotope exchange technique (IET) with the conventional Sieverts method, microcalorimetry, breakthrough experiments and multi-scale modelling to comprehensively and quantitatively investigate the thermodynamics ... -
Understanding the progress and challenges in the fields of thermo-catalysis and electro-catalysis for the CO2 conversion to fuels
( Institute for Ionics , 2024 , Article Review)The need to limit anthropogenic CO2 emissions and lower the atmospheric CO2 concentration makes CO2 conversion an imminent requirement. Availability of suitable facilities and prior understanding how electro and thermal ...
