“…Therefore, the addition of nanoparticles to liquid medium will increase the electric conductivity similar to ions. Fal et al 58 and Yang et al 59 confirmed these predictions through experimental measurements of conductivity values of silica nanoparticle-containing suspensions. They found conductivity to vary linearly with particle concentration, and a higher particle concentration led to elevated conductivities.…”

Nanofluids are stable mixtures of nanoscale particles dispersed in base fluids with good prospects in enhanced oil recovery in the petroleum industry. In this review, the mechanisms and evaluation methods of stable nanofluids were analyzed. The effects of nanoparticles on viscosity, electrical conductivity, and surface/interfacial tension of base fluids were discussed. The results of laboratory research and field tests revealed that nanofluids could improve the oil recovery through plugging and profile control, transformation of wettability of rock surface, changes in oil−water interface properties, and increases in the viscosity ratio between fluids. On the other hand, nanoparticles might stabilize oil−water emulsions produced during the extraction stage, adversely affecting subsequent oil−water separation processes, especially the electrical dehydration. However, careful analysis suggested lack of in-depth studies regarding the impacts of nanoparticles on droplet coalescence inside electro-dehydration plants. The present analyses will hopefully assist future investigations in nanofluidics.

“…They found that in the UV region, the absorption of the nanofluid increased by increasing the volume concentration of the nanoparticles. Fal [14,15], Murshed [16] and Estellé [17] have also contributed to the literature of nanofluids. Nanofluids have been widely studied in by the research community and which has led to numerous achievements.…”

A nonlocal fractional model of Brinkman type fluid (BTF) containing a hybrid nanostructure was examined. The magnetohydrodynamic (MHD) flow of the hybrid nanofluid was studied using the fractional calculus approach. Hybridized silver (Ag) and Titanium dioxide (TiO2) nanoparticles were dissolved in base fluid water (H2O) to form a hybrid nanofluid. The MHD free convection flow of the nanofluid (Ag-TiO2-H2O) was considered in a microchannel (flow with a bounded domain). The BTF model was generalized using a nonlocal Caputo-Fabrizio fractional operator (CFFO) without a singular kernel of order α with effective thermophysical properties. The governing equations of the model were subjected to physical initial and boundary conditions. The exact solutions for the nonlocal fractional model without a singular kernel were developed via the fractional Laplace transform technique. The fractional solutions were reduced to local solutions by limiting α → 1 . To understand the rheological behavior of the fluid, the obtained solutions were numerically computed and plotted on various graphs. Finally, the influence of pertinent parameters was physically studied. It was found that the solutions were general, reliable, realistic and fixable. For the fractional parameter, the velocity and temperature profiles showed a decreasing trend for a constant time. By setting the values of the fractional parameter, excellent agreement between the theoretical and experimental results could be attained.

“…TMC as a photocatalyst resulted in a 79% photo degradation of MB dye. The increased photocatalytic activity in the TMH system can be ascribed to interfacial contact and high electrical conductivity, which allow charge carrier transfer at the interface and hence increased photocatalytic activity [37].…”

2D/1D-MoS2/TiO2 heterostructures have proven to be vigorous for photocatalytic applications. The enhancement in photocatalytic activity of heterostructures may get influenced by the accumulation of strain at the interface that affects the interfacial interaction. Keeping that in view, present paper reports the strain accumulated interfacial modification of 2D/1D-MoS2/TiO2 heterostructures for the enhancement of photocatalytic activity. Two different synthesis methods such as hydrothermal and chemical vapour deposition (CVD) method are used for the growth of MoS2 on TiO2 nanostructures. Micro-Raman spectroscopy revealed that strain is accumulated at the interface on growth of MoS2 over TiO2 nanostructures. It is further revealed that the MoS2/TiO2 heterostructure synthesized by CVD method induces compressive strain. Also, heterostructures synthesize by hydrothermal method induces tensile strain that modify the charge separation at the interface, which was further confirmed by X-ray photoelectron spectroscopy (XPS). Moreover, ultraviolet photoelectron spectroscopy (UPS) revealed that the upward band bending in the MoS2/TiO2 heterostructures synthesized by hydrothermal method. Similarly, heterostructure synthesized by chemical vapour method (CVD) shows the downward band bending that leads to the improved charge separation at interface. The modified interface of heterostructures is further studied for electrochemical measurement using cyclic voltammetry (CV) and photocatalytic activity by degradation of model compound.
