Summary: In recent years, the development of nanofluids has opened up new possibilities for research in renewable energy, particularly in the field of Direct Absorption Solar Collectors (DASCs). Researchers have made rapid progress in studying the optical characteristics of nanofluids, which can significantly enhance photothermal conversion. This study introduces a numerical model that assesses the performance of DASCs using mono and hybrid nanofluids. The model solves radiation transfer equations and thermal energy equations in a participating medium while considering realistic solar spectrum and optical properties of copper and alumina nanoparticles. The study also examines the sensitivity of DASC performance to design and operation parameters, as well as the influence of copper and alumina nanoparticles. Additionally, the technoeconomic impact of Cu-Al2O3 hybrid nanofluid at different volume fractions is investigated using response surface methodology, and a multi-objective optimization is performed to maximize DASC efficiency and minimize the total cost of the working fluid.

Summary: In this study, oil-based ZnO/MWCNTs binary nanofluids and ZnO/MWCNTs/Au ternary hybrid nanofluids are proposed. The effects of nanoparticles concentration and the ratio of ZnO and MWCNTs on the optical properties and photothermal conversion performance are experimentally analyzed. The results show that ZnO/MWCNTs nanofluids exhibit slightly higher optical absorption performance than MWCNTs, and adding gold nanoparticles (Au NPs) to form ZnO/MWCNTs/Au nanofluids further enhances their absorption performance in the visible region. Moreover, the photothermal conversion efficiency of ZnO/MWCNTs nanofluids reaches the maximum value (91.2%), and the photothermal conversion efficiencies of MWCNTs and ZnO/MWCNTs/Au nanofluids are increased by 35.6% and 42.8%, respectively.

Summary: Nanofluids, as a new generation of fluids, have shown to be more suitable for heat transfer applications compared to conventional fluids, with the type of nanoparticles dispersed being a key parameter. This review focuses on the different types of particles used in nanofluid research, particularly in solar collectors, exploring their impact on heat transfer and the classification of nanoparticles. Studies suggest that Al2O3-based nanofluids are widely considered in solar collectors, with non-metallic based nanofluids potentially more efficient for enhancement. Negative aspects such as thermo-physical instability and reduced efficiency at high nanoparticle volume fraction are also highlighted, along with suggestions for future research directions.

Summary: In this study, molybdenum disulfide (MoS2) nanoparticles were obtained through liquid phase exfoliation with the presence of chitosan, and then melt mixed with linear low-density polyethylene (LLDPE) to produce novel antimicrobial active packaging materials. These nanoparticles formed aggregates that were well dispersed in the polymer matrix, providing several functionalities to the LLDPE, including antimicrobial behavior and changes in surface properties. Despite significantly increasing water vapor permeation, MoS2 showed a decrease in oxygen permeation. The nanocomposites exhibited promising potential for the development of antibacterial active packaging films without compromising the mechanical properties of the pure LLDPE matrix.

Summary: The performance of Pumped Thermal Electricity Storage (PTES) systems and their integration with thermal power plants (TPP) are assessed in this study. Different alternatives for two-tank molten salt storage and charge/discharge systems are simulated and evaluated. The integrated PTES configurations achieve an average Round-Trip Efficiency (RTE) of around 50%-65% and high energy and power density. The argon heat pump is recommended for Rankine cycle configurations with a higher RTE of over 63%. Brayton and air heat pump configurations have similar RTE, but are sensitive to operational parameters and have lower energy density. A more suitable Thermal Energy Storage (TES) system is required. The potential implementation of the studied system relies on exploiting energy and power density to create cost-effective systems.

Summary: The calculation of direct normal irradiance is crucial for solar thermal technologies, but it is expensive. Three methods (regression analysis, probabilistic approach, and machine learning models) are discussed in the literature for calculating direct normal irradiance. A new methodology is proposed to demonstrate the effectiveness of machine learning models in estimating solar radiation, using one measure data as input and training a deep neural network model based on a reference station. The results show that the proposed approach is a viable methodology with similar or superior performance compared to separation models.

Summary: This study evaluates the radiation effects on the thermal behavior of a packed bed using a discrete model and a novel method called Layer View Factor. The research finds that radiation flattens the temperature profiles and accelerates the evolution of thermocline length in the packed bed. The stand-by process shows the largest impact, with a maximum temperature difference of 100K compared to the non-radiation case. The discharge temperature drops below 90% of the charge temperature when radiation is included.
