TL;DR: In this article, the initial stage of steam generation is mainly caused by localized boiling and vaporization in the superheated region due to highly non-uniform temperature and radiation energy distribution, albeit the bulk fluid is still subcooled.

TL;DR: In this paper, the photothermal conversion efficiency (PTE) of gold nanofluids in a cylindrical tube under natural solar irradiation conditions was also compared with a developed 3-D numerical model.

TL;DR: In this article, a well-controlled experiment was performed using three different categorised nanofluids, i.e., gold, copper, carbon black, and their hybrids, to assess their performance in terms of photothermal conversion efficiency (PTE), specific absorption rate (SAR), and materials cost.

TL;DR: In this article, the authors compared the performance of gold and carbon black nanoparticles in terms of evaporation rate, materials cost and energy consumption, and concluded that gold nanoparticles are not feasible for solar evapotion applications, where the cost of producing 1 g/s vapour is ∼300 folds higher than that produced by carbon black nanofluids.

TL;DR: In this paper, the photothermal conversion performance of six commonly used nanomaterials in direct absorption solar collectors (DASC) was investigated under a focused simulated solar flux, and the contribution of sensible heating and latent heat of vaporization of the nanofluids was revealed in context of their photothermal performance.
