Photothermal and recycling properties of new composite magnetic nanofluids

Stability, Thermophysical, Optical and Photothermal Properties of ZnO Nanofluids with Added Anionic/Cationic Mixed Surfactants

“…However, when the volume fraction of ZnO nanofluids is greater than 1.551%, the temperature growth rate of the base liquid decreases with the increase of the volume fraction. 50 This can be caused by two factors: 1. A higher volume fraction leads to a darker fluid color, incident light cannot penetrate the nanofluids, and the fluid inside and at the bottom can only be heat transferred by radiative heat transfer between particles.…”

Photothermal Conversion and Thermal Management of Magnetic Plasmonic Fe3O4@Au Nanofluids

“…The reason is that when the concentration of Fe 3 O 4 @Au is too high, a large number of nanoparticles undergo adsorption settling to the bottom, thus making fewer particles in the NFs and reducing the photothermal conversion. [ 39,40 ]…”

“…The reason is that when the concentration of Fe 3 O 4 @Au is too high, a large number of nanoparticles undergo adsorption settling to the bottom, thus making fewer particles in the NFs and reducing the photothermal conversion. [39,40] To further investigate the thermal distribution of Fe 3 O 4 @Au NFs using external magnetic field, a common magnet is placed one side of beaker, and the thermocouple is set on the side near the magnet and on the opposite side away from the magnet to record the temperature of fluids at different sites, as shown in Figure S2, Supporting Information. According to Figure 6b, under the influence of external magnetic field, Fe 3 O 4 @Au nanoparticles aggregate around the magnet, leading to higher photothermal conversion than the sites where the magnetic field strength is weak, showing the well thermal management using external magnetic field.…”

Ti3C2Tx and copper sulfide composite nanofluids with a hierarchical structure for sustainable and efficient solar light–thermal conversion

“…The conception of nanouids was rst introduced by researchers from the Argonne National Laboratory in the United States, which involves dispersing metallic or nanometallic powders into different media such as water, alcohol, and oil to prepare a uniform and stable new media system. [13][14][15] However, conventional dispersion media suffer from issues such as poor stability and high viscosity, which can cause pipeline blockages. Therefore, it is necessary to develop new dispersion media to overcome these problems.…”
