Nanofluid preparation is a crucial step in view of their thermophysical properties as well as the intended application. This work investigates the influence of ultrasonication duration on the thermal conductivity of Fe3O4 nanofluid. In this work, water-based Fe3O4 nanofluids of various volume concentrations (0.

The present work pertains to synthesis of Sm-doped GO/KSrPO (GO/KSrPO:Sm) nanocomposite using ultrasound-assisted method. Successful decoration of graphene oxide sheets with the KSrPO:Sm phosphor was confirmed using analysis techniques including SEM, EDS, UV/visible spectrometry, XRD, and FTIR of the prepared GO/KSrPO:Sm nanocomposite. Further, photocatalytic activity of this nanocomposite material was studied by examining degradation of methylene blue (MB) dye from water.
