In the thermal treatment, the pristine Ni shell was exposed to oxygen so that the porous NiO shell was formed as a priority. When outward diffusion of the Ni is faster than the inward diffusion of the Ni at the elevated temperature, the void appears at the inside of the core/shell interface and then grows up until the hollow interior structure forms due …
To ensure a stable energy supply, the intermittent nature of these energy sources necessitates the development of efficient and dependable energy storage solutions [6, 7]. LHTES systems offer a valuable means of storing excess energy generated during periods of high supply and releasing it during periods of high demand, thereby improving …
However, the interfacial polymerization method is more suitable for the production of phase change energy storage microcapsules compared to in situ polymerization [14]. In situ polymerization methods often result in a wide range of capsule sizes due to the difficulties in controlling droplet or emulsion formation and subsequent …
For example, the shell supported by the core guarantees the specific surface architecture depending on the porosity, surface area, etc., leading to superior …
Correspondingly, an energy storage density of 3.16 J/cm 3, with an boosting of 320 % in comparing with that of PEN, is achieved. This stretched SPEN@CCTONR/PEN film with leaped energy storage density would be a promising candidate for future flexible
Among several applications of core–shell MOFs (energy storage, water splitting, sensing, nanoreactors, etc.), their application for energy storage devices will be meticulously reviewed. CSMOFs for supercapacitors and different batteries (Li-S, Li-ion, Na- ions, Li-O 2, KIBs, Li-Se, etc.) will be discussed.
Ultrasonic treatment provides higher input of energy into the reaction system compared to high-speed mixing resulting in formation of nanometer-sized …
Generally, the methods which are being used in the process of the surface coating of the energy storage materials are as follows: 3.1. Wet chemical coating …

The mix designs of thermal energy storage concrete were adopted from two mix designs of OPKS concrete (Shafigh et al., 2011; Serri et al., 2014).The OPKS was fully replaced by composite PCM in these mix designs. The details of mix designs used are ...
The wettability of surfaces is usually controlled by the surface free energy and surface texture, and by reducing the surface free energy, the hydrophobicity of materials can be improved distinctly. In this paper, FAS-17 is used to reduce the surface free energy of the films owing to the existence of –CF 3 and –CF 2 –, whose surface …
Compared with traditional energy storage technologies, mobile energy storage technologies have the merits of low cost and high energy conversion efficiency, can be …
The effective reduction of sulfur pollutant emissions during the treatment of waste resins has always posed a challenge. This study put forward a solution to using the metallic oxide enhanced Na 2 CO 3-K 2 CO 3 system for the treatment of waste resins (CERs). Na 2 CO 3-K 2 CO 3 was used as a medium for heat transfer and …
Numerical analysis of the effect of the iso-surface fin redistribution on the performance enhancement of a shell-and-tube latent heat thermal energy storage unit for low-temperature applications. Journal of Energy Storage, 2022, 56, pp.105892.
The melting process of industrial grade paraffin wax inside a shell-and-tube storage is analyzed by means of numerical simulation and experimental results. For this purpose, the enthalpy porosity method is extended by a continuous liquid fraction function. The extended method is tested using results gained from a gallium melt test inside a …
