“…Other salts are reportedly able to slow down the setting process of MPCs: the inclusion of Zn(NO 3 ) 2 in proportions ranging from 1 to 4% by weight with respect to the solid was observed to delay the setting of the MPC, slow down the increase in the pH, and delay the hydration exothermic peak of the MPC, while decreasing its compressive strength [ 116 ]. Also, CaCl 2 ·6H 2 O can increase the setting time from about 5 min to 30 min when present in proportions ranging from 0 to 2.5% [ 187 ]. This additive was determined to be not very effective in reducing the temperature increase during setting, since 55 °C was reached even at the highest CaCl 2 concentration tested; however, it did not hamper the compressive strength of the material.…”

In the search for effective biomaterials for bone repair, magnesium phosphate cements (MPCs) are nowadays gaining importance as bone void fillers thanks to their many attractive features that overcome some of the limitations of the well-investigated calcium-phosphate-based cements. The goal of this review was to highlight the main properties and applications of MPCs in the orthopedic field, focusing on the different types of formulations that have been described in the literature, their main features, and the in vivo and in vitro response towards them. The presented results will be useful to showcase the potential of MPCs in the orthopedic field and will suggest novel strategies to further boost their clinical application.

“…[137,138] In buildings, PCM can be integrated into envelopes, such as walls, roofs, and floors. [139][140][141] Fu et al [142] prepared expanded perlite (EP) / CaCl2•6H2O composites, in which EP can adsorb 55 wt% CaCl2•6H2O. The composite PCM is then embedded into bricks to form PCM bricks and compared with commercial foam insulation bricks.…”

It is necessary to develop new technologies for energy storage and use of renewable energy to improve energy efficiency. Phase change materials (PCMs) are a family of energy storage materials that are among one of the most suitable materials for storing and effectively utilizing renewable thermal energy. PCM-based latent heat storage (LHS) is more advantageous than sensible energy storage because of the high storage energy density per unit volume/mass and the smaller temperature difference between storing and releasing heat. However, PCMs have low a thermal conductivity and a high degree of supercooling that are affecting their efficiency for energy storage. This review article first introduces the principle of phase change energy storage and the classification of phase change energy materials. Then, the improvement of storage methods of PCMs, and the fundamental properties that affect the application of phase change materials are discussed in detail. The applications of PCMs in various fields are also reviewed, including in solar energy utilization, waste heat recovery, construction, and civil and medical use. Finally, it summarizes the research progress of PCMs and provides an outlook for future research.

“…With a suitable phase transition temperature of around 29 °C and a high phase transition enthalpy of 209 J g −1 , calcium chloride hexahydrate (CaCl 2 ·6H 2 O) is a suitable PCM with great potential for waste heat recovery and energy-efficient building construction. 35,36 However, the problems of supercooling and phase separation of CaCl 2 ·6H 2 O still exist, which limit its practical application. 37,38 The addition of nucleating agents can provide nucleation sites for the crystallization process thus reducing the subcooling degree.…”
