“…The degree of carbonization was controlled by adjusting the microwave heating duration. Guo et al [ 69 ] prepared three NFs of graphene oxide (GO), multiwalled CNTs, and Ti 3 C 2 in 1-Butyl-3-methylimidazolium tetrafluoroborate. Commercial samples of GO and CNTs were used, while Ti 3 C 2 was synthesized using a solvent etching method.…”

Owing to their superior optical and thermal properties over conventional fluids, nanofluids represent an innovative approach for use as working fluids in direct-absorption solar collectors for efficient solar-to-thermal energy conversion. The application of nanofluids in direct-absorption solar collectors demands high-performance solar thermal nanofluids that exhibit exceptional physical and chemical stability over long periods and under a variety of operating, fluid dynamics, and temperature conditions. In this review, we discuss recent developments in the field of nanofluids utilized in direct-absorption solar collectors in terms of their preparation techniques, optical behaviours, solar thermal energy conversion performance, as well as their physical and thermal stability, along with the experimental setups and calculation approaches used. We also highlight the challenges associated with the practical implementation of nanofluid-based direct-absorption solar collectors and offer suggestions and an outlook for the future.

The properties and applications of MXenes (a family of layered transition metal carbides, nitrides, and carbonitrides) have aroused enormous research interests for a decade since the successful synthesis of few‐layer transition metal carbides in 2011. Though MXenes, as the building blocks, have already been applied in various fields (such as wearable electronics) owing to the distinctive optical, mechanical and electrical properties, their thermal stability and intrinsic thermal properties were less thoroughly investigated compared to other characteristics in early reports. The pioneering theoretical prediction of the thermoelectric nature of MXenes was performed in 2013 while the first experiment‐based report concerning the degradation behavior of the 2D structure at elevated temperatures in a controlled atmosphere was published in 2015, followed by numerous discoveries regarding the thermal properties of MXenes. Herein, after a brief description of the synthesis, this Review summarized the latest insights into the thermal stability and thermophysical properties of MXenes, and further associated these unique properties with relevant applications by multiple examples. Finally, current hurdles and challenges in this field were provided along with some advices on potential research directions in the future.

Solar energy systems have been recognized as a significant component of HVAC systems during the last two decades, providing thermal and electrical energy for a variety of applications. Meanwhile, nanofluid-based Direct Absorption Solar Collectors (DASCs) hold great potential for converting solar radiation to thermal energy in energy systems since nanoparticles significantly improve the energy-absorbing potential of the base fluid. The primary impediment to commercializing these collectors is the sedimentation and agglomeration of nanoparticles over an extended period of time. The novel design of direct absorption solar collector was modelled in this study by COMSOL software using water and silver nanofluid as the working fluid and the effect of pulsating flowrate on the DASC's performance was investigated in order to increase efficiency and reduce nanoparticle sedimentation and agglomeration. According to the results, collector efficiency can be increased by using pulsing flowrates, and this improvement is much more pronounced when nanofluid is employed as the working fluid, increasing efficiency to 84.2 percent. The energy efficiency of the DASC rises by 5% and 3% with pulsing flowrates for silver nanofluid and water, respectively. Thus, using pulsating flowrate in the direct absorption solar collector can grow thermal efficiency while simultaneously preventing nanoparticle deposition and aggregation in the collector. The findings of this research can pave the way for the use of nanofluid-based direct absorption solar collectors in a variety of energy systems.
