        Phase Change Materials (PCMs) for heat storage and energy saving has been extensively used in many fields for heating and cooling processes, including building, solar energy, textiles, agriculture, and electronics. PCMs have been getting incredible attention for being low-cost materials and have potential materials for thermal energy storage (TES) with long cycle life. Though, the disadvantages such as flow, result in encapsulation in three scales of Macro, Micro and Nano capsules. Encapsulating PCM reduces the disadvantages and improves the efficiency of PCMs. Different methods for producing PCMs in the scale of nano and core-shell materials, have been developed and the capsules size in relation to parameters such as pH, stirring rate, material selection and preparation method have been investigated. In recent years, this subject has been extensively studied, seeking to find more efficient and safer PCMs. In this context, nanoscale PCMs have been produced and applied to the most diverse products and their performance evaluated. They simply modified and optimized production processes. The novelty of this study lies in the fact that merely a few articles have reviewed nano-encapsulating of PCMs, focusing on new developments on PCM nano-capsules. Moreover, few articles have compared nano and microcapsules of PCMs so far. The analyzed papers suggest that the production methods influence the size of the obtained capsules. The purpose of this article is to make an updated review of the synthesis and application of nano-encapsulated PCMs. Manuscript profile

        This systematic review aims at investigating different wound dressings commonly used for the healing process and skin repair. Five databases, namely SCOPUS, Web of Science, Medline, Google Scholar, and Cochrane Database of Systematic Reviews, up to 2020, were scanned for papers specific to the topic of concern. The blinded randomized controlled trials, in vivo and in vitro studies comparing common wound dressings, including traditional, natural/biological, and artificial ones were studied in the present review. Finally, the researchers selected 22 studies. From which the data related to the clinical features of wound dressings and their advantages and disadvantages) were derived. The review of literature suggests that many treatment combinations are utilized as wound dressings based on the wound type and hospital guidelines. Nevertheless, there are conflicting views about the most appropriate choice. The findings of the reviewed articles indicate that hydrogels are the most common wound dressing used for wounds and burns due to high thermal/mechanical stability and low water evaporation. However, it is suggested to apply hybrid hydrogel membranes to overcome the low mechanical strength of a single component Manuscript profile
