This study aimed to improve metformin skin administration by creating solid lipid microparticles (SLMs). To obtain optimal metformin delivery, SLMs were created using a double emulsion hot homogenization technique with a rotor‐stator. The effects of the two surfactants and homogenization time on particle characteristics and performance were studied using Response Surface Methodology (RSM). Tween 60 concentration had the most significant effect on particle size. The simple effects of the studied factors did not significantly affect encapsulation efficiency. However, the interactions between these parameters influenced this response. Moreover, the particle size was affected more by the surfactant concentration. After optimizing the three factors, the results showed an optimum encapsulation efficiency of 82% and a particle size of 2 µm with a desirability of 0.915. The topical drug release profile of lipid microparticle suspensions is characterized by an early burst, followed by sustained drug release. The release of metformin from solid lipid particles followed the Higuchi release model, whereas it followed the Weibull model for release from the gel formulation. Based on the in vitro drug release results, we can conclude that the particles containing the drug are in the shape of a matrix.Practical Applications: The SLM formulation produces a film on the cutaneous surface, retaining the active component in the skin's superficial layer. Furthermore, owing to their micron size, SLM increases the contact surface of the encapsulated drug with the stratum corneum, which might improve cutaneous delivery and provide sustained release of the drug.

“…Recently, scientists have been focusing on such thermal storage systems by investigating the properties of PCMs, such as a high storage capacity for low-temperature applications. Various strategies have been attempted to improve the efficiency of these heat recovery systems, including encapsulation [ 7 , 8 ], the use of fins [ 9 ], and nanoparticle incorporation [ 10 ]. Thus, heat exchanger configurations containing PCMs have been investigated, both numerically and experimentally, as latent heat thermal storage systems [ 11 ].…”

Among the different types of phase change materials, paraffin is known to be the most widely used type due to its advantages. However, paraffin’s low thermal conductivity, its limited operating temperature range, and leakage and stabilization problems are the main barriers to its use in applications. In this research, a thermal energy storage unit (TESU) was designed using a cylindrical macroencapsulation technique to minimize these problems. Experimental and numerical analyses of the storage unit using a tubular heat exchanger were carried out. The Ansys 18.2-Fluent software was used for the numerical analysis. Two types of paraffins with different thermophysical properties were used in the TESU, including both encapsulated and non-encapsulated forms, and their thermal energy storage performances were compared. The influence of the heat transfer fluid (HTF) inlet conditions on the charging performance (melting) was investigated. The findings demonstrated that the heat transfer rate is highly influenced by the HTF intake temperature. When the effect of paraffin encapsulation on heat transfer was examined, a significant decrease in the total melting time was observed as the heat transfer surface and thermal conductivity increased. Therefore, the energy stored simultaneously increased by 60.5% with the encapsulation of paraffin-1 (melting temperature range of 52.9–60.4 °C) and by 50.7% with the encapsulation of paraffin-2 (melting temperature range of 32.2–46.1 °C), thus increasing the charging rate.
