An experimental study was conducted to investigate the structural stability of ethylene glycol-based titanium dioxide nanoparticle suspensions (nanofluids) prepared by two-step method. The effects of particle concentration, fluid temperature, shear rate and shear duration were examined. Particle size and thermal conductivity measurements in quiescent state indicated the existence of aggregates ...

The interactions between platinum complexes and human serum albumin (HSA) play crucial roles in the distribution, metabolism, and activity of platinum-based anticancer drugs. Octahedral platinum (IV) complexes represent a significant class of anticancer agents that display molecular pharmacological properties different from cisplatin. In this study, the interaction between two Pt(IV) complexes ...

in this work, for the first time, the rheological properties of nanofluids of lanthania nanoparticles (nps) in ethylene glycol (eg) as functions of shear rate, volume fraction, and temperature were measured. the results showed that both eg and the nanofluids behave as non-newtonian fluids at lower shear rates and transform to newtonian fluids at higher shear rates. the values of viscosity for b...

A considerable growth of interest in electrowetting (EW) has stemmed from the potential exploitation of this technique in numerous industrial and biological applications, such as microfluidics, lab-on-a-chip, electronic paper, and bioanalytical techniques. The application of EW to droplets of liquids containing nanoparticles (nanofluids) is a new area of interest. Understanding the effects of e...

Hybrid nanofluids aim to further improve the characteristics of mono nanofluids. However, experimental studies that jointly explore physical properties hybrids and corresponding are missing. In this work, B4C TiB2 hybrid TiB2:B4C nanoadditives used for first time design based on propylene glycol:water 20:80 wt%. The density, isobaric heat capacity, thermal conductivity determined by oscillating...

The rheological behaviour of ethylene glycol-based nanofluids containing hexagonal scalenohedral-shaped α-Fe2O3 (hematite) nanoparticles at 303.15 K and particle weight concentrations up to 25% has been carried out using a cone-plate Physica MCR rheometer. The tests performed show that the studied nanofluids present non-Newtonian shear-thinning behaviour. In addition, the viscosity at a given s...

in this study, thermal performance of a cylindrical heat pipe is investigated numerically. three different types of water based nanofluids, namely (al2o3+water), (diamond+water) and (multi-wall carbon nano tube (mwcnt) +water) have been used. the influence of using the simple nanofluids and mwcnt nanofluid on the heat pipe characteristics such as liquid velocity, pressure profile, temperature p...

Disposition and transportation of anticancer drugs by human serum albumin (HSA) affects their bioavailability, distribution and elimination. In this study, the interaction of a set of anticancer drugs with HSA was investigated by molecular dynamics and molecular docking simulations. The drugs' activities were analyzed according to their docking scores, binding sites and structural descriptors. ...

Nanofluids with enhanced thermal properties are candidates for thermal management in automotive systems, with scope for improving energy efficiency. In particular, many studies have reported on dispersions of nanoparticles with long-term stability in the base fluid, with qualitative evaluations of the dispersion stability via either the naked eye or optical instruments. Additives such as surfac...
