Recently, the research team led by Xue Yahui from the Department of Mechanics and Aerospace Engineering at the Southern University of Science and Technology has made breakthrough progress in the research of micro- and nanomechanics and related interdisciplinary fields. The relevant results were published in the internationally renowned journal Nano Letters. The paper is titled "Voltage-Gated Nanofluidic Synapse with Cation-π interactions Enabled Ultra-Long-Term Memory". The publication of this achievement has attracted widespread attention from academic circles both domestically and internationally. Here, our company extends warm congratulations to the research team led by Xue Yahui from the Department of Mechanics and Aerospace Engineering at the Southern University of Science and Technology on their achievements.

Since joining the Southern University of Science and Technology in 2021, Associate Professor Xue Yahui has been dedicated to exploring fields such as micro- and nano-mechanics, intelligent artificial ion channels, micro- and nano-flow control and heat transfer, and acoustic-mechanical metamaterials. His team has long focused on revealing the multi-scale mechanical behaviors and mechanisms of liquids at the interface of micro- and nano-structures. By utilizing new materials and methods, they have tackled key scientific challenges such as the wetting stability of micro- and nano-structures, and the controllability of liquid and ion transport at the nanoscale and atomic scale. Their research findings hold significant application prospects in various fields such as energy, environmental engineering, and medicine.

In recent research, our research team successfully fabricated voltage-controlled graphene channels of specific dimensions, achieving ultrafast and selective ion transport under voltage switch control. Experimental data reveals that the equivalent diffusion coefficient of ions within these channels is two orders of magnitude higher than that in water, marking the fastest ion diffusion transport observed to date, even surpassing the equivalent diffusion coefficient of ions in existing biomembrane channels. Through optical reflectance experiments, our team measured the charge density of the graphene channels in situ under voltage control, discovering an ultra-high charge density distribution within the channels. We established a mean-field theory to predict the equivalent diffusion coefficient of ions within atomic-scale graphene channels, and the theoretical predictions closely matched the experimental results, unveiling the cooperative movement mechanism of ions within extremely confined nanoscale channels. This discovery not only deepens our understanding of the rapid and selective ion transport mechanism within biological channels but also provides theoretical basis and technical support for designing controllable and ultrafast ion transport devices for technologies such as ion batteries, seawater desalination, and medical dialysis.

Independent technology empowers cutting-edge exploration and facilitates scientific breakthroughs beyond boundaries

In the research conducted by Xue Yahui's research team at the South University of Science and Technology of China on "Realizing Ultra-Long Memory in Voltage-Gated Nanofluidic Synapses with Cation-π Interactions", the NE-PE13FH plasma cleaner independently developed by Nano Technology played a significant role in the graphene processing step. This processing step is a crucial part of the device preparation and testing process, laying the foundation for the smooth progress of subsequent electrical testing and ensuring the accuracy and reliability of test results. It aids the research team in better exploring the characteristics and related mechanisms of voltage-gated nanofluidic synapses.
