“…Wang et al 127 added 1 wt % copper nanoparticles to the water-based PCM and found that the subcooling of the PCM was reduced by 20.5%, and the total cooling time was reduced by 19.2%. Camila et al 128 added spherical carbon black nanoparticles, CNTs, and graphene oxide nanosheets to PCMs and found that nanoparticles can reduce the supercooling of the material. Among them, spherical carbon black nanoparticles have the greatest effect on the undercooling of the PCM, which can reduce the undercooling at 5 °C.…”

The use of cold storage devices to store energy at low peaks of power usage and release it at peaks is an economic measure. It is also one of the main means to solve the imbalance between electricity shortages during the day and abundance at night. Adding cold storage balls equipped with phase change materials (PCMs) into water cold storage devices can utilize the sensible heat of water and the latent heat of PCMs for cold storage, which has a high energy storage density and can provide cold water with a suitable temperature. PCMs can be divided into organic phase change materials (OPCMs) and inorganic phase change materials (IPCMs), but both have defects. Adding additives or other materials to them to form composite phase change materials (CPCMs) can obtain suitable thermal properties. In the process of material application, some PCMs have problems of poor thermal conductivity (TC) and liquid leakage. The use of additives such as expanded graphite (EG), metal foam, and nanoparticles is a better solution to the above problems. In recent years, many scholars have researched PCMs and additives for increasing thermal conductivity (AITC). However, there is still a lack of detailed comparison among EG, metal foam, and nanoparticles. This article will introduce the PCMs used in the temperature zone (TZ) of cold storage air-conditioning systems (CSASs) and analyze their advantages, disadvantages, and improvement methods. This paper will focus on the latest research on the effect of additives such as nanoparticles, EG, and metal foam on the TC of PCMs. It will also compare the special effects of AITC in preventing supercooling, preventing phase separation, preventing leakage of liquid PCMs, and flame retarding. The future research directions of AITC will be discussed.

“…This could be as a result of the differences in diffusion rates of the material change with the aspect ratio of the material (e.g., higher drag on a tubular structure compared to a perfect sphere) or because of steric hindrance in the collisions as the morphology limits inter-particular interactions [43]. Several reports have addressed the role of shape and size on cellular internalization [44][45][46].…”

Cerium oxide nanoparticles have been used in a number of non-medical products over the years. The therapeutic application of these nanoparticles has mainly been due to their oxidative stress ameliorating abilities. Their enzyme-mimetic catalytic ability to change between the Ce3+ and Ce4+ species makes them ideal for a role as free-radical scavengers for systemic diseases as well as neurodegenerative diseases. In this review, we look at various methods of synthesis (including the use of stabilizing/capping agents and precursors), and how the synthesis method affects the physicochemical properties, their behavior in biological environments, their catalytic abilities as well as their reported toxicity.

The utilization of the paraffin phase change material (PCM) in solar energy storage systems is limited by its low thermal conductivity, easy leakage, and insensitivity to solar energy. In the present study, the solution combustion synthesis method was applied to fabricate a porous carbon matrix that is embedded with Cu nanoparticles (Cu@C). The shape-stabilized composite PCM was prepared by vacuum impregnation of liquified paraffin. The paraffin/Cu@C composite retained a high latent heat storage enthalpy of 148.2 J/g. The thermal conductivity of the composite was increased to 145% compared to that of pure paraffin. Due to the strong capillary absorption feature of the porous matrix, the composite also indicated a good anti-leakage property. Additionally, the Cu@C matrix also endowed the composite PCMs with good photo-thermal transformation capability, implying their potential application in solar thermal energy storage.
