Experimental and theoretical investigations into structural, morphological and optical characters of the Al2O3, CuO and ZnO-based nanofluids for interfacial tension reduction

This research elucidates interfacial tension behavior of nanofluid of Al2O3, CuO and ZnO. The synthesis was facilitated by sol gel method. The features are elaborated by employing SEM, XRD and RAMAN. The soft of CASTEP Material studio was considered to simulate energy band gap, partial density of states and dielectric constant. The interfacial tension analysis was conducted by placing crude oil. The outcomes reveal that dielectric behaviour along with interfacial tension significantly varies across the nanofluids. The extravagant performance of ZnO-based nanofluid is witnessed in comparison to other contemporaries. This extent of decrement remained 11.3% using ZnO-based nanofluid.
