Summary: This paper studies the application of TiN-modified h-BN nanosheets in direct absorption solar collectors (DASCs) to improve the efficiency of solar-thermal absorbers. The nanosheets exhibit superior solar absorptivity and thermal conductivity due to the plasma plasmon effect of nanoparticles and the high thermal conductivity of h-BN nanosheets. Five different concentrations of TiN@h-BN composite nanofluids were prepared and analyzed for stability, optical properties, thermal loss, and exergic efficiency. By combining localized surface plasmon resonance (LSPR) and h-BN light reflection properties, the photothermal conversion efficiency of the nanofluids in DASCs was improved. The study provides new strategies for utilizing solar energy and controlling the photothermal properties of nanofluids.

Summary: The experimental investigation on the viscosity of nanofluids with Fe3O4 nanoparticles and carbon nanotubes (CNTs) showed new empirical formulas for accurate viscosity predictions. Surfactants like TMAH, SDS, and SLS were found to improve stability, reduce viscosity, and enhance thermal conductivity in Fe3O4-water, CNT-water, and Fe3O4-CNT-water nanofluids. The CNT-water and Fe3O4-CNT-water nanofluids exhibited shear-thinning behavior, while water-based Colace-Fe3O4, TMAH-Fe3O4, and TSC-Fe3O4 nanofluids displayed linear rheological behavior.

Summary: In this study, the stability, thermal conductivity, and viscosity of MXene/water nanofluids were systematically investigated, and thermophysical prediction models were developed. It was found that adding anhydrous sodium citrate and prolonging ultrasonication time to 60 min significantly improved the stability. The thermal conductivity of 0.1 wt% freshly prepared nanofluid increased by 27.41% at a temperature of 60 degrees C compared to water. Surprisingly, the viscosity remained almost constant over the range of 0-0.1 wt%. Artificial neural network models showed a satisfactory agreement between predicted and experimental values for thermal conductivity and viscosity, with relative errors within ±1.5% and ±5% respectively. This study is expected to contribute to the advancement of nanofluids.

Summary: This work focuses on the study of the convective heat transfer and pressure drop characteristics of a hybrid nanofluid. Multi-walled carbon nanotube (MWCNT) NF, Fe3O4 NF, and MWCNT/Fe3O4 HNFs with different concentrations were prepared. The convective heat transfer coefficient and pressure drop were investigated and compared. The results showed that the MWCNT/Fe3O4 HNFs exhibited higher heat transfer coefficients and larger pressure drops compared to the base fluid, indicating their potential as an effective heat transport medium.

Summary: This study investigates the use of metakaolin, pumice powder, and silica fume as partial replacements for cement in recycled aggregate concrete (RAC). The SCMs are used to coat the surface of the recycled concrete aggregate (RCA) and fill the gaps and pores of the adhered mortar present on it. The results show that the treated RAC specimens achieved significantly higher compressive strength, with silica fume exhibiting the highest strength improvement. The strength enhancement in the silica fume specimens is attributed to the development of a stronger interfacial transition zone (ITZ) and the formation of strength-inducing compounds like calcium silicate hydrate (C-S-H), as validated by microstructural investigation using scattered electron microscopy (SEM).
