“…PCMs can absorb large amounts of thermal energy at a certain temperature without getting hotter. In 2018, Pourmohamadian et al prepared SrTiO 3 microencapsulated palmitic acid (PA) for PCMs devices . Pristine PA itself has a lower decomposition temperature, and the weight loss can be observed in between 170°C and 270°C.…”

Summary With the increasing demand and depleting trend of commercial energies, it has forced the researchers all over the world to accelerate research and development in the area of renewable energy. Currently, unique and interesting features of binary compounds have gained more attention by researchers, and it became a favourite research topic among various groups of researchers around this world. It was noticed that strontium titanate (SrTiO3) consists of several extraordinary properties that can apply for miscellaneous applications especially for energy storage, fuel cells, as well as to generate hydrogen fuel via photocatalysis process. Besides that, it was noticed that SrTiO3 can be synthesised in different pathways. The method of preparation and amount of precursors can affect the surface properties of SrTiO3. Thus, this article presents a critical review on how SrTiO3 synthesis methods affect its surface morphology and the applications of SrTiO3 in various fields.

“…However, there are still limitations to the solubility and stability of curcumin although many methods such as liposome 45 , polymeric nanoparticles 46 , solid lipid nanoparticles (SLNs) 47 , albumin nanoparticles 48 , microemulsions and nanoemulsions 49 , nanospheres, and microcapsules 50 have been devised in recent years to obtain a higher aqueous solubility, bioavailability, activity, and lower toxicity 28,51 . In this regard, the emulsion method has received much attention in recent decades due to containing a simple synthesizing process and high efficiency, as well as requiring low costs, and eco-friendly materials [52][53][54][55][56] . This method has been exerted to synthesize water-insoluble substances 57,58 , oils 59,60 , plant extracts 61,62 , proteins 63 , nucleic acids 64 , curcumin, and many other substances 49 for drug delivery intentions, while some of these materials have been evaluated even in nanofiber scaffolds [65][66][67] .…”

Curcumin contains many biological activities as a natural bioactive substance, however, its low solubility stands as a huge bioavailability disadvantage. Recently, different methods have been developed for utilizing the tremendous medicinal properties of this material. In this study, an Oil/Water nano-emulsion of curcumin (Nano-CUR) has been woven in zein polymer at three percentages of 5%, 10%, and 15% (v/v). We have investigated the physicochemical properties of nanofibers (NFs) including FESEM, FTIR, tensile strength, encapsulation efficiency, and release profile, as well as biological properties. According to the data, the NFs have been observed to become significantly thinner and more uniformed as the involved percentage of Nano-CUR had been increased from 5 to 15%. It is considerable that the tensile strength can be increased by heightening the existing Nano-CUR from 5% towards 15%. The resultant NFs of zein/Nano-CUR 15% have exhibited higher in vitro release and lower encapsulation efficiency than the other evaluated zein/Nano-CUR NFs. It has been confirmed through the performed viability and antioxidant studies that zein/Nano-CUR 10% NFs are capable of providing the best conditions for cell proliferation. Considering the mentioned facts, this work has suggested that Nano-CUR can be successfully woven in zein NFs and maintain their biological properties.

A novel microencapsulated phase change material (PCM) with a Palmitic acid (PA) core and Copper (II) carbonate (CuCO 3 ) shell was successfully fabricated through a self-assembly method. Fourier transform infrared (FT-IR) spectroscopy, X-ray diffractometer (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to determine the chemical compositions, crystalloid phase, microstructure and morphology of PA@CuCO 3 microcapsules, respectively. The thermal properties and thermal stability of microcapsules were determined by differential scanning calorimetry (DSC) and a thermogravimetric analysis (TGA). The XRD and FT-IR results indicated the presence of all of the characteristic peaks of PA and CuCO 3 and proved that no chemical reaction had occurred between them. The SEM images showed a regular spherical morphology with rough surfaces for the PA@CuCO 3 microcapsule with average diameters ranged from 1.5 to 2 μm, and the TEM image confirmed the PA core to have been well encapsulated by CuCO 3 . In the DSC analysis results, the microcapsules indicated similar phase change behaviors as those of pristine PA, and the typical samples were melted at 66.9°C with a latent heat of 48.85 J/g and frozen at 55.7°C with a latent heat of 43.29 J/g for a microencapsulation ratio of 43.92%. TGA analyses indicated that the thermal stability of the PA was further improved due to the protection of the PA core encapsulated by the CuCO 3 shell.[a] Dr.step degradation behavior over a temperature range of 200-310°C, which is attributed to the decomposition of PA and CuCO 3 , respectively. It is clear from Figure 5 (parts b, c, and d) that the PA@CuCO 3 microcapsule samples all exhibited a maximum weight loss at higher temperatures in comparison with the pristine PA, which indicates that the CuCO 3 shells can improve the thermal stability of PA in the microcapsule.Using DSC, the phase change behaviors and latent heats of the pristine PA and PA@CuCO 3 microcapsules with different core/shell mass ratios were investigated.
