“…In this new work, a co-precipitation method was used to prepare nanoparticles, where NaOH was used as the precipitating agent and serves as a terminator for growing the nano-particles because the particles cannot come together easily. Furthermore, it expands during the calcination process, which is why the temperature was 80 • C for 10 h and 600 • C for 3 h. The same procedure was followed for the synthesis of other nanomaterials, that is, GO and ZnO [28]. To make a nanofluid sample in base fluid, a measured amount of nano powder was mixed with a given base fluid volume and the acquired mixture was sonicated for 30 min before starting the photothermal conversion experiment.…”

The solar absorption efficiency of water as a base-fluid can be significantly improved by suspending nanoparticles of various materials in it. This experimental work presents the photo thermal performance of water-based nano-fluids of graphene oxide (GO), zinc oxide (ZnO), copper oxide (CuO), and their hybrids under natural solar flux for the first time. Nanofluid samples were prepared by the two-step method and the photothermal performance of these nanofluid samples was conducted under natural solar flux in a particle concentration range from 0.0004 wt % to 0.0012 wt %. The photothermal efficiency of water-based 0.0012 wt % GO nanofluid was 46.6% greater than that of the other nanofluids used. This increased photothermal performance of GO nanofluid was associated with its good stability, high absorptivity, and high thermal conductivity. Thus, pure graphene oxide (GO) based nanofluid is a potential candidate for direct absorption solar collection to be used in different solar thermal energy conversion applications.

Unprecedented quantitative assessment of the swelling behavior of surface‐immobilized photothermal responsive microgels (PTRM) is reported. The PTRM were prepared by incorporating plasmonic gold nanoparticles (AuNPs) in thermo‐responsive cationic microgels based on poly(N‐isopropylacrylamide) (BM). The stimuli‐responsive behavior of the microgels was investigated in aqueous suspensions using Dynamic Light Scattering (DLS) and on surfaces using a Quartz Crystal Microbalance with Dissipation (QCM‐D) as well as with the Surface Forces Apparatus (SFA). Both the BM and PTRM in aqueous suspensions underwent a similar temperature‐induced volume phase transition at around 35°C. The complexation of AuNPs with the BM led to a decrease in the surface charge allowing to increase the surface grafting density. This favored a unidirectional upward swelling of the surface immobilized PTRM. The study reports significant photo‐triggered swelling responses on surface with decreases in film thickness up to 82%.
