... T was applied, finding that increased magnetic field strength raised the thermal properties of the structure. Guo et al. [23] investigated advanced phase change composite (PCCs) reinforced with porous carbon rolls enriched with Cu-NPs from cotton fabric. These rolls enhanced thermal transport among layers. ...

... Among the various TES approaches, latent heat thermal storage (LHTS) systems utilizing phase change materials (PCMs) have attracted considerable research interest due to their high energy storage density and nearly isothermal phase transition behavior [7][8][9]. However, the widespread implementation of PCMs is hindered by their inherently low thermal conductivity, typically ranging between 0.1 and 0.96 W/m K for materials such as paraffin wax and molten salts, which significantly limits their heat transfer performance and prolongs the melting/solidification duration [10][11][12][13][14]. ...

... In addition to the ice template mentioned above, other materials such as biomass templates [63], biomass cotton fiber templates [64], sodium chloride templates [65], cotton-derived porous carbon fiber templates [66], wood templates [67], and liquid filmassisted gas templates [68], etc., also had been reported to use as the sacrificial template to constructed the 3D directional filler networks. The common process is to first fabricate the sacrificial templates, then fill pre-prepared thermal conductivity fillers into the template, and finally remove the templates to obtain the 3D interconnected framework with anisotropic structure. ...

... Thermal energy storage has been widely employed due to its capacity to satisfy the requirements of electricity and space heating, as well as to mitigate the fluctuations in energy demand. The primary thermal energy storage technologies encompass sensible heat storage, latent heat storage, and chemical energy storage [1]. In view of the complex reversible chemical reactions inherent in chemical energy storage, which give rise to a plethora of considerations in the control process, the forms of sensible heat and latent heat storage are more conducive to building applications. ...

... Carbonylation is an important means for introducing carbonyl groups into organic molecules, such as those widely used in the chemical industry and organic synthesis. 1 Roelen was the rst to report the carbonylation reaction process in 1938, and it has more than 80 years history of research and application. Precious metal catalysts of Pd, Ru, and Rh as well as non-precious metal catalysts of Co and Ni have been successfully used in carbonylation reactions. ...

... Nonetheless, to the best of our knowledge, no study has been undertaken into the influence of the amount of metal foam on the level of improvement in the thermal properties of PCM. In previous studies [43,44], the authors used only copper foam to enhance the thermal conductivity of paraffin. In the current research, we added hypered nanoparticles to increase the thermal conductivity of paraffin, especially in the pores area inside the foam metal, which will fill with paraffin and not obtain the benefit of the high Titanium dioxide volume fraction (%) Wt sample weight average vsample volume of the sample thermal conductivity of the copper. ...
