A novel calcium chloride hexahydrate-based deep eutectic solvent as a phase change materials

Direct sulfation of cellulose fibers using a reactive deep eutectic solvent to produce highly charged cellulose nanofibers

“…Therefore, molar ratio of 1:3 between sulfamic acid and urea can be seen as the optimum, especially in application where low viscosity is requested. At room temperature, all the DESs were stiff gels, which slowly started to crystallize, indicating that DESs exhibited a supercooling behavior (Shahbaz et al 2016;Doherty and Acevedo 2018).…”

Binary mixtures of fatty alcohols and fatty acid esters as novel solid‐liquid phase change materials

“…Therefore, this is an effective way to use solar energy and improve energy efficiency of buildings. 2,3 Solid-liquid PCMs are preferred due to their capability of storing and releasing large amounts of heat within a narrow range of temperature. A PCM impregnated into building walls must have a high latent heat and high thermal conductivity.…”

“…A PCM impregnated into building walls must have a high latent heat and high thermal conductivity. 2,3 They should also have a melting temperature slightly above 20°C to meet the need of thermal comfort of the building. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the recommended comfort room temperature is 21.0°C to 23.0°C in winter and 23.5°C to 25.5°C in summer.…”

“…The PCM must have a long lifetime, be compatible with building materials, noncorrosive, nontoxic, and show no degradation after numerous cycles. 2,3 Solid-liquid PCMs are preferred due to their capability of storing and releasing large amounts of heat within a narrow range of temperature. Solid-liquid PCMs used in buildings can be classified into three major groups: inorganic compounds, organic compounds, and eutectics of inorganic and/or organic compounds.…”

Experimental studies on cycling stable characteristics of inorganic phase change material CaCl2·6H2O-MgCl2·6H2O modified with SrCl2·6H2O and CMC

“…Inorganic hydrated salts, as the behalf of inorganic PCMs, have become a hot area of research due to their low cost, easy availability, non-flammability and high energy storage density. Common inorganic hydrated salts include CaCl2·6H2O [10][11][12][13], Na2SO4·10H2O [14][15][16][17] and CH3COONa·3H2O [18][19][20][21]. Because inorganic hydrated salts have poor nucleation property and are easy to melt incongruently, the current research work focuses on solving supecooling and phase separation.…”
