Benchmarking the Self-Assembly of Surfactin Biosurfactant at the Liquid–Air Interface to those of Synthetic Surfactants
Onaizi, Sagheer A.; Nasser, M.S.; Al-Lagtah, Nasir M.A. ( Springer-Verlag , 2016 , Article)The adsorption of surfactin, a lipopeptide biosurfactant, at the liquid–air interface has been investigated in this work. The maximum adsorption density and the nature and the extent of lateral interaction between the ... -
Effect of the degree of template removal from mesoporous silicate materials on their adsorption of heavy oil from aqueous solution
Twaiq, Farouq; Nasser, M.S.; Onaizi, Sagheer A. ( Springer VerlagHigher Education Press , 2014 , Article)The key aim of this study is to evaluate the adsorption of heavy oil from aqueous solutions with different oil contents over mesoporous silicate materials having different surfactant template contents. The mesoporous ... -

Nasser, M. S.; Onaizi, Sagheer A.; Hussein, I. A.; Saadd, M. A.; Al-Marri, M. J.; Benamor, A.... more authors ... less authors ( Elsevier B.V. , 2016 , Article)In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ... -
A review for Metal-Organic Frameworks (MOFs) utilization in capture and conversion of carbon dioxide into valuable products
Al-Rowaili, Fayez Nasir; Zahid, Umer; Onaizi, Sagheer; Khaled, Mazen; Jamal, Aqil; AL-Mutairi, Eid M.... more authors ... less authors ( Elsevier Ltd , 2021 , Article Review)Carbon dioxide (CO2) has become a primary atmospheric greenhouse gas that has stirred up numerous energies and environmental-related mishaps around the world. Its unwelcome contribution to the decay of the global ecosystem ... -
Self-assembly of a surfactin nanolayer at solid-liquid and air-liquid interfaces
Onaizi, Sagheer A.; Nasser, M. S.; Al-Lagtah, Nasir M.A. ( Springer Verlag , 2016 , Article)Surfactin, a sustainable and environmentally friendly surface active agent, is used as a model to study the adsorption of biosurfactants at hydrophobic and hydrophilic solid–liquid interfaces as well as the air–liquid ...
