TL;DR: In this paper, a review of electrical energy storage technologies for stationary applications is presented, with particular attention paid to pumped hydroelectric storage, compressed air energy storage, battery, flow battery, fuel cell, solar fuel, superconducting magnetic energy storage and thermal energy storage.

TL;DR: In this article, Titanate nanotubes of an aspect ratio of ~ 10 are synthesized, characterised and dispersed in water to form stable nanofluids containing 0.5, 1.0 and 2.5 wt.% of the nanotsubes.

TL;DR: In this paper, the authors show that the presence of nanoparticles enhances thermal conduction under macroscopically static conditions mainly due to nanoparticle structuring / networking, while the natural convective heat transfer coefficient decreases systematically with increasing nanoparticle concentration, and the deterioration is partially attributed to the high viscosity of nanofluids.

TL;DR: In this paper, the authors discuss how the nanoparticle structuring affects the thermal conductivity and viscosity of nanofluids and how the two transport properties are related through the nanoparticles.

TL;DR: In this paper, a review of the recent development in the field including both hydrodynamics and heat transfer of gas-solid two-phase mixtures flowing through packed beds is presented.
