Nanofluids are recent nanomaterials with improved thermophysical properties that could enhance the efficiency and reliability of heat transfer systems. Relevant for calculation, thin film flows, droplet impingements or microfluidic surface tension wettability. However, to date, understanding those in nanofluids field is at beginning compared transport properties. At this stage, review focus on effect nanoparticles base fluid nature, temperature, use surfactant, nanoparticle concentration,...
Homogeneous stable suspensions obtained by dispersing dry TiO2 nanoparticles in pure ethylene glycol were prepared and studied. Two types of nanocrystalline structure analyzed, namely anatase rutile phases, which have been characterized scanning electron microscopy. The rheological behavior was determined for both nanofluids at nanoparticle mass concentrations up to 25%, including flow curves frequency-dependent storage loss moduli, using a cone-plate rotational rheometer. effect temperature...

This paper presents the preparation and thermal/physical characterization of phase change materials (PCMs) based on poly(ethylene glycol) 400 g·mol-1 nano-enhanced by either carbon black (CB), a raw graphite/diamond nanomixture (G/D-r), purified (G/D-p) or nano-Diamond nanopowders with purity grades 87% 97% (nD87 nD97, respectively). Differential scanning calorimetry oscillatory rheology experiments were used to provide an insight into thermal mechanical changes taking place during...
This paper focuses on an experimental study of the surface tension nanofluids based ethylene glycol with various types nitride nanoparticles. Samples were prepared using a two-step method mass content between 1 and 5% particles. Nanofluids contain three nanoparticles: aluminum nitride, silicon titanium particle average sizes. Surface was investigated at constant temperature 298.15 K two different techniques: du Noüy ring pendant drop method. It is presented that values obtained both methods...
The skin of yellowfin tuna is one the fishery industry solid residues with greatest potential to add extra value its circular economy that remains yet unexploited. Particularly, high collagen content fish allows generating gelatin by hydrolysis, which ideal for forming hydrogels due biocompatibility and gelling capability. Hydrogels have been used as drug carriers local administration their mechanical properties loading capacity. Herein, novel were designed vehicles two structurally...
