“…The long alkyl chain could be easily absorbed on the graphite surface, also enhanced by π-stacking interactions of benzene and delocalized π-electron of graphite [29], thus improving the surface coverage degree of graphite [30]. On the other side, SO3groups strengthen the electrostatic repulsion between DBSA-covered graphite due to screened Coulomb interactions, thus stabilizing the surfactant adsorbed onto particles and avoiding particle aggregations also thanks to the presence of the long alkyl chain [31].…”

A recent trend in micro EDM is the addition of powders into the dielectric. The presence of powders helps to lower the dielectric breakdown voltage and therefore the discharge occurs early. As a result, the discharge energy is better distributed, resulting in a greater number of discharges, each with less energy. The main advantage of using this method is the improvement of both the process performance and surface finishing of the workpiece. A critical aspect of the implementation of this technology is in general the management of the powder. In fact, to obtain advantages during the machining, the powders should be maintained dispersed into the dielectric to avoid their aggregation. This paper aims to study the concentration of the powder and the surfactant in the dielectric fluid on micro EDM drilling performance. Titanium alloy was used as workpiece material, hydrocarbon oil as dielectric, graphite as powder and 4dodecylbenzenesulfonic acid as surfactant. The performance was evaluated considering the Material Removal Rate, the Tool Wear Ratio and the geometrical characteristics of the holes (overcut and taper rate). Graphite content positively affected both Material Removal Rate and Tool Wear Ratio; a larger spark gap was observed as well. The use of surfactant is required for mix stability but increasing its percentage generally reduces the effects of graphite and increases data dispersion as well.

“…To fabricate electronic textiles, Trovato et al deposited vertically aligned carbon nanotubes (VACNT) and dispersed them in 4-dodecylbenzenesulfonic acid combined with silica-based sol-gel precursors, then compounded it with a polyurethane thickener and coated the cotton surfaces [ 119 ]. The composite showed a sheet resistance value less than 4.0 × 10 4 ± 6.7 × 10 3 Ω/sq and was tested as a humidity-sensing material.…”

In recent years, studies concerning Organic Bioelectronics have had a constant growth due to the interest in disciplines such as medicine, biology and food safety in connecting the digital world with the biological one. Specific interests can be found in organic neuromorphic devices and organic transistor sensors, which are rapidly growing due to their low cost, high sensitivity and biocompatibility. This trend is evident in the literature produced in Italy, which is full of breakthrough papers concerning organic transistors-based sensors and organic neuromorphic devices. Therefore, this review focuses on analyzing the Italian production in this field, its trend and possible future evolutions.

“…with textile substrates (non-conductive in nature) is an important aspect of e-textiles fabrication. The electrically functionalized textile substrate of different forms ranging from fiber/filament to fabric/garment can be achieved via different approaches, i.e., coating (dip-coating [65,66], spray coating [67,68], ultrasonic coating [69,70], knife coating [71,72], spin coating [73,74], etc. ), printing (screen printing [75,76], inkjet printing [77,78], extrusion printing [79,80], gravure printing [81,82], laser printing [83,84], stencil printing [85,86], 3D printing [87,88], etc.…”

Flexible electronic textiles are the future of wearable technology with a diverse application potential inspired by the Internet of Things (IoT) to improve all aspects of wearer life by replacing traditional bulky, rigid, and uncomfortable wearable electronics. The inherently prominent characteristics exhibited by textile substrates make them ideal candidates for designing user-friendly wearable electronic textiles for high-end variant applications. Textile substrates (fiber, yarn, fabric, and garment) combined with nanostructured electroactive materials provide a universal pathway for the researcher to construct advanced wearable electronics compatible with the human body and other circumstances. However, e-textiles are found to be vulnerable to physical deformation induced during repeated wash and wear. Thus, e-textiles need to be robust enough to withstand such challenges involved in designing a reliable product and require more attention for substantial advancement in stability and washability. As a step toward reliable devices, we present this comprehensive review of the state-of-the-art advances in substrate geometries, modification, fabrication, and standardized washing strategies to predict a roadmap toward sustainability. Furthermore, current challenges, opportunities, and future aspects of durable e-textiles development are envisioned to provide a conclusive pathway for researchers to conduct advanced studies.
