Article Synopsis
- Researchers have developed a new method to create polyester nanocomposites by synthesizing calcium borate nanoparticles while simultaneously polymerizing polyethylene terephthalate (PET), eliminating the need for organic solvents.
- * This innovative approach allows for the incorporation of very low amounts (0.1 wt%) of nanoparticles with strong bonding, leading to improved dielectric properties and breakdown strength in the resulting materials.
- * The PET-based nanocomposites achieve high energy storage capabilities, with a maximum discharged energy density of 15 J/cm³, making it a promising and environmentally friendly alternative to existing dielectric polymers for scalable production.
We investigated the bipolar resistive switching (BRS) properties of Mn-doped NiO thin films by sol-gel spin-coating. As the Mn doping concentration increased, lattice constant, grain size and band gap were found to decrease simultaneously. Moreover, the electroforming voltages and threshold voltages were gradually reduced.

The switching behaviors have been strongly dependent on compliance current (CC) and switching processes. It shows reproducible URS and BRS after electroforming with low and high CC of 1 and 3 mA, respectively, which is contrary to previous reports.
