“…It can also be observed from figure 4(b) that 4 vol% ZnO-EG ink had the lowest viscosity compared to the other concentrations. A similar behavior has been observed for ZnO-EG nanofluids and other metal oxide-glycol dispersions [33,[35][36][37][38][39]. The decrease in viscosity with addition of metal oxide nanoparticles has been attributed to the formation of hydrogen bonds between the nanoparticles and glycol molecules and disturbance in the native hydrogen bonding network of glycol and this phenomenon has been described in detail elsewhere [25,34].…”

In this work, we describe the preparation of a zinc oxide-ethylene glycol nanoparticle ink and the parameters that control the printing using a custom-built direct writer system. The ink (nanoparticle dispersion) was prepared using a two-step wet synthesis method, without using any surfactant. Its viscosity was found to be in the suitable range for printing and straight lines were printed on cleaned glass substrates. The influence of various printing parameters, such as total dispersed volume, number of printed layers, substrate temperature, drying temperature and time, and particle loading, on the morphology of the printed patterns was investigated. In-situ and post-printing drying of the printed pattern, at the same temperature, produced different morphologies, which can be attributed to the direction of heat transfer and solvent removal. Optimization of these printing parameters enabled us to obtain a continuous printed pattern with uniform morphology using a direct writing system, which can be extended to a variety of nanoparticle based inks.

This paper presents the buoyancy effects on the magneto-hydrodynamics stagnation point flow of an incompressible, viscous, and electrically conducting nanofluid over a vertically stretching sheet. The impacts of an induced magnetic field and viscous dissipation are taken into account. Both assisting and opposing flows are considered. The overseeing nonlinear partial differential equations with the associated boundary conditions are reduced to an arrangement of coupled nonlinear ordinary differential equations utilizing similarity transformations and are then illuminated analytically by using the optimal homotopy investigation strategy (OHAM). Graphs are introduced and examined for different parameters of the velocity, temperature, and concentration profile. Additionally, numerical estimations of the skin friction, local Nusselt number, and local Sherwood number are explored using numerical values.

“…Nanoparticles-induced perturbation in the hydrogen bonds of strongly hydrogen bonded liquids causes reduction in viscosity [8,20,[24][25][26][27][28]. Hence ZnO-propylene glycol interactions are more favorable than ZnO-water interactions.…”
