Highly Efficient ZnO/hBN:PVA-Based Multibit Memristor Array for Edge Computing Harsh Ranjan, Chandra Prakash Singh, Vivek Pratap Singh, Parthasarathi Pal, Saurabh Kumar Pandey IEEE Transactions on Electron Devices, 2026 This work demonstrates a robust and reliable memristive heterostructure device comprising a zinc oxide (ZnO) buffer layer incorporated with a solution-processed hexagonal boron nitride (hBN):polyvinyl alcohol (PVA) nanocomposite. The fabricated device supports memory functionality, exhibiting low-voltage SET and RESET processes with operating voltages below 2 V with a <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${R}_{\mathrm{OFF}}/{R}_{\mathrm{ON}}$</tex-math> </inline-formula> ratio greater than 200. Furthermore, the device demonstrates a 2-bit multilevel cell (MLC) storage capability and exceptional thermal robustness, maintaining stable performance and retaining the data at <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$110~^{\circ } $</tex-math> </inline-formula>C for over <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$10^{{4}}$</tex-math> </inline-formula> s. In addition, the fabricated device architecture also exhibits a stable analog switching behavior, emulating biological long-term potentiation (LTP) and long-term depression (LTD) with high cycle-to-cycle uniformity and low device-to-device variability, achieving a functional device yield of 72%. The device nonlinearity is analyzed and fit, and system-level simulations using the MNIST dataset achieve a high classification accuracy of 91.4%, demonstrating the efficacy of trap-mediated weight updates. These results highlight the strong potential of 2-D nanomaterial–polymer heterostructures for scalable, high-density, and thermally stable neuromorphic hardware applications for edge computing.
Microwave-Assisted Synthesis and Characterization of Iron Oxide Nanoparticles for Advanced Biomedical Sensing Applications Vivek Pratap Singh, Chandra Prakash Singh, Santosh Kumar, Saurabh Kumar Pandey, Deepak Punetha IEEE Open Journal of Nanotechnology, 2025 This study focuses on the synthesis and characterization of Superparamagnetic Iron Oxide Nanoparticles (IONPs) with potential biomedical and sensing applications. These nanoparticles are in high demand for their biocompatibility, biodegradability, and superparamagnetic properties. In contrast to traditional high-temperature synthesis methods, microwave-assisted co-precipitation provides notable benefits, such as improved superparamagnetic characteristics, a high surface-to-volume ratio, large surface area, and simplified separation processes. The synthesis process utilized microwave-assisted co-precipitation, and a range of characterization techniques, including XRD, FESEM, VSM, FTIR, and UV-spectroscopy, were employed to assess the properties of the iron oxide nanoparticles. Analysis of the XRD, FTIR, and UV-spectroscopy results confirmed the formation of IONPs, predominantly comprising magnetite (Fe3O4). The microwave-synthesized IONPs exhibited superparamagnetic behavior, featuring an average crystallite size of 9 nm and robust saturation magnetization values (up to 68 emu/g). These attributes render them highly suitable for applications such as MRI contrast agents, thermal mediators in hyperthermia, drug delivery systems, and advanced sensor technologies, including magnetic sensing and biosensing applications, where their high magnetic responsiveness and surface functionalization capabilities can be effectively leveraged.
