Finally, the experimental thermal conductivity results were compared and validated against the Maxwell effective model. The exceptional enhancement in the thermal conductivity of the bare Fe 3O 4 NP-based ferrofluid compared to that of the Fe 3O core–shell NP-based ferrofluid was due to the more pronounced effect of the chain-like network formation/clustering of bare Fe 3O 4 NPs in the base fluid. Ru/RuO2 core-shell nanoparticles were synthesized by electrochemical method in water without the addition of stabilizers. Similarly, an enhancement in the thermal conductivity of ∼153% and ∼116% was recorded for Fe 3O 4 ( ca. 7 nm) NP-based ferrofluids compared to the base fluid, respectively. Exceptional results were obtained, where the electrical conductivity was enhanced up to ∼3222% and ∼2015% for Fe 3O 4 ( ca. The electrical and thermal conductivities of Fe 3O 4 NPs and Fe 3O core–shell NP-based ferrofluids were measured using different concentrations of NPs and with different sized NPs. The magnetic characterization revealed that the as-synthesized small average-sized Fe 3O 4 NPs ( ca. Herein, we report the investigation of the electrical and thermal conductivity of Fe 3 O 4 and Fe 3 O 4 carbon (Fe 3 O 4 C) coreshell nanoparticle (NP)-based ferrofluids. The thickness of the carbon shell over the Fe 3O 4 NPs was found to be in the range of ∼1–3 nm. The average particle size of Fe 3O 4 NPs and Fe 3O core–shell NPs was found to be in the range of ∼5–25 nm and ∼7–28 nm, respectively. Au cores with three morphologies including nanocubes, nanorods, and nanospheres are successfully. Herein, we report a simple and universal method to synthesize AuTiO 2 coreshell nanostructures. Different sized Fe 3O 4 NPs were synthesized via a chemical co-precipitation method followed by carbon coating as a shell over the Fe 3O 4 NPs via the hydrothermal technique. 2 coreshell nanostructures with various core morphologies, as well as tunable shell thickness and crystallinity, is of great signi cance. Herein, we report the investigation of the electrical and thermal conductivity of Fe 3O 4 and Fe 3O (Fe 3O core–shell nanoparticle (NP)-based ferrofluids.
