Hollow halloysite nanotubes have been used as nanocontainers for loading and for the triggered release of calcium hydroxide for paper preservation. A strategy for placing end-stoppers into the tubular nanocontainer is proposed and the sustained release from the cavity is reported. The incorporation of Ca(OH)₂ into the nanotube lumen, as demonstrated using transmission electron microscopy (TEM) ...

Thermal energy storage (TES) facilitates the integration of renewable by decoupling production and consumption, mitigating intermittence issues. However, current TES systems use fossil fuel-based products as media, so development sustainable efficient materials should be investigated. This work aims to design characterization new eco-friendly nanoenhanced phase change (NePCMs) based on dispersi...

At present, special attention is paid to the issues of increasing wear resistance surface layers material rubbing parts and reducing energy consumption for friction. It possible form films with high tribological properties by introducing various metal-containing additives into base oil, which, depending on design technological features friction pair operating conditions, can differ significantl...

Abstract In this study, the improvement in SAE 10W-40 engine oil tribological performance after addition of magnesium oxide (MgO) nanoadditive and two different phosphonium-based ionic liquids (ILs) was investigated. Besides, rheological behaviour MgO-based nanolubricant IL-based hybrid nanolubricants at temperature range from 293.15 to 363.15 K studied. The nanoparticle characterization perfor...

The main target of the current research work is effectively eliminating fossil fuel dependency and improving exhaust air quality conventional Compression Ignition (CI) engines. This paper demonstrates for first time that a nanofluid (water without surfactant) stored in separate tanks can be quantified, collected, immediately emulsified by high shear mixer before transfer into combustion chamber...

• Eight nanolubricants based on two different pristine graphene nanoplatelets were tribologically studied. Graphene with larger lateral size showed better stability in the base oil. 0.055 wt% nanolubricant concentration revealed highest friction and wear reduction for GnP40 GnP7, respectively. Tribofilm formation surface repairing lubrication mechanisms due to nanoadditives detected worn steel ...

This work presented an endeavour to fabricate sustainable and eco-friendly polyethersulfone (PES) ultrafiltration membranes. A novel graft copolymer (Poly(Maleic Anhydride-Co-Glycerol)) (PMG) have been synthesized via a facile rapid route impart their hydrophilic features onto the final PES membrane. series of characterization tools, for both nanoadditives nanocomposite membranes, harnessed con...
