“…In this case, HCACF declined to zero in 0.5 ps and the nature of this decay is oscillatory, which is due to back scattering of phonons carrying thermal energy with the solid nanoparticles. This type of behaviour also reported previously [5]. The integral of the HCACF is directly related to heat conductivity.…”

The thermal conductivity of ethylene-glycol based ZnO nanofluid is computed using Equilibrium Molecular Dynamics Simulations in the Green-Kubo framework, taking into account the impact of nanoparticle volume fraction and nanofluid temperature. Mean square displacement (MSD) of the liquid phase for base fluid and nanofluid is also studied to investigate the thermal conductivity enhancement mechanism.

“…Owing to good electrical conductivity and adsorption capacity, they can be used to construct gas sensors for ppm-level ethanol gas detection [235]. The thermal conductivity of EG solvent can be enhanced ~24% by introducing Cu@C colloids after 30 min-LAL of Cu [236], making the colloid suitable as nanofluids. CuO x /GO composites synthesized by in situ LAL can be transformed into high-performance Cu/ rGO composite catalysts via NaBH 4 reduction [237].…”

Diverse nanomaterials, in the forms of carbides, sulfides, oxides, metals, hydroxides, etc., have been synthesized by laser ablation in liquids (LAL) with metal targets as the dominant educts. Many advantages of LAL technique itself and its products have been revealed since 1983 when the first report about LAL was released. Different from traditional wet-chemical synthesis, one unique feature of LAL is its resultant extreme high-temperature and high-pressure local environment for the nucleation and growth of nanomaterials, despite being performed at room temperature. This extreme condition can induce the atomization and ionization of the target materials and liquid molecules to incur different chemical reactions. The laser, liquid, liquid additive, and target can significantly alter the local environment in a broad range. Thus, different phases and shapes of nanomaterials are producible even from the same target. Through directly comparing the products of LAL of 13 kinds of chosen representative metals synthesized under different conditions, this review presents and discusses current understandings, challenging issues, and perspectives related to the diversity of LAL-products, which is willing to promote a deeper investigation and discussion on a clear clarification of the chemical reactions and particle nucleation/growth processes.

“…Haider et al 12 theoretically and numerically explored the impact of the nanoparticle shape on a water-based aluminium oxide nanofluid moving towards a solid cylinder with the consequences of heat transfer. Khamliche et al 13 used Cu nanoparticles to create high thermal conductivity nanofluids. Gangadhar et al 14 examined the two-dimensional boundary flow layer of a nanofluid over a stretched surface using the spectrum relaxation method.…”
