“…To conclude, the setting of the ES apparatus can be constructed in several ways, showing that in theory, the researcher's creativity and knowledge in the area of interest have a great impact when it comes to developing suitable materials. Here, it was observed that some studies were concerned about the interference from the external environment in the manufacturing of MPs when employing ES technology inside a camera [16,31,45], compared to recent studies, which have opted not to use the camera [20,39]. From this comparison, one might conclude that there is no necessity for using a camera for controlling the temperature and humidity of the medium in order to obtain MPs.…”

“…Moreover, Sander et al investigated the influence of doping with NaCl in the manufacturing of polyvinylpyrrolidone (PVP) MPs by ES and concluded that this doping does not improve atomization in terms of particle size. Moreover, no effect on the particle size distribution was observed [20]. Furthermore, through the connection of a teflon capillary, the location of the syringe pump in relationship to the collector could be facilitated (Figure 2e,f,h,i) [31].…”

“…ES is considered a part of EHDA [17,19]. Generally, ES consists of components such as a high voltage source, a syringe pump (SP), a spray head, and a collector [12,20,21]. ES proceeds by forcing a liquid through a capillary to a collector under a potential drop, on the order of kilovolts (kV), which is applied between the capillary and the collector [22].…”

“…From the 10% polymer solution, despite the presence of MPs obtained from the technique, there was a substantial increase in the amount of fibers obtained. Several groups have demonstrated the tuning of the polymer concentration for the generation of MPs, for instance Faramarzi et al employed PLGA at a polymer and solvent ratio of 2% (w/v) and Sander et al used PVP at a ratio of 5% and 10% (w/v) for the generation of MPs, respectively [20,39].…”

“…According to previous reports, the importance of the parameters for mass and volume during the preparation of the polymer solution for the ES are eminent for the final products, and in general, a ratio between 2% and 10% (w/v) are recommended for obtaining MPs [10,12,20,39,40,55]. Within this framework, Figure 4a illustrates how the concentration of the polymer would impact the outcome of the ES process and generate products, where low polymer concentrations (well-diluted solutions) would provide MPs (Figure 4(a.1)).…”

Microparticles (MPs) with controlled morphologies and sizes have been investigated by several researchers due to their importance in pharmaceutical, ceramic, cosmetic, and food industries to just name a few. In particular, the electrospray (ES) technique has been shown to be a viable alternative for the development of single particles with different dimensions, multiple layers, and varied morphologies. In order to adjust these properties, it is necessary to optimize different experimental parameters, such as polymer solvent, voltage, flow rate (FR), type of collectors, and distance between the collector and needle tip, which will all be highlighted in this review. Moreover, the influence and contributions of each of these parameters on the design and fabrication of polymeric MPs are described. In addition, the most common configurations of ES systems for this purpose are discussed, for instance, the main configuration of an ES system with monoaxial, coaxial, triaxial, and multi-capillary delivery. Finally, the main types of collectors employed, types of synthesized MPs and their applications specifically in the pharmaceutical and biomedical fields will be emphasized. To date, ES is a promising and versatile technology with numerous excellent applications in the pharmaceutical and biomaterials field and such MPs generated should be employed for the improved treatment of cancer, healing of bone, and other persistent medical problems.

The properties of materials play a significant role in triboelectric nanogenerators (TENGs). Advanced triboelectric materials for TENGs have attracted tremendous attention because of their superior advantages (e.g., high specific surface area, high porosity, and customizable macrostructure). These advanced materials can be extensively applied in numerous fields, including energy harvester, wearable electronics, filtration, and self‐powered sensors. Hence, designing triboelectric materials as advanced functional materials is important for the development of TENGs. Herein, the structural modification methods based on electrospinning to improve the triboelectric properties and the latest research progress in this kind of TENGs are systematically summarized. Preparation methods and design trends of nanofibers, microspheres, hierarchical structures, and doping nanomaterials are highlighted. The factors influencing the formation and properties of triboelectric materials are considered. Furthermore, the latest progress on the applications of TENGs is systematically elaborated. Finally, the challenges in the development of triboelectric materials are discussed, thereby guiding researchers in the large‐scale application of TENGs.
