    The amplitude curve. by Ruocheng Zhang (20442445)

    Published 2024
    “…As the ultrasonic vibration frequency (20–40kHz) increases, the mechanical specific energy (MSE) initially decreases and then increases. The MSE reaches a minimum value at a frequency of 20–25 kHz, representing a decrease of 15.52%–22.24% compared with conventional rock breaking, which can significantly improve the rock breaking efficiency and reduce the drilling cost. …”

    Regional Characteristics in Ultradeep MXene Slit Nanopores: Insights from Molecular Dynamics Simulation by Kaiqing Sun (18715965)

    Published 2025
    “…When charging is completed, a distinct ion layering structure emerges. As the interlayer spacing varies, the ion distribution in the electrode pores exhibits regional characteristics: in the ordered region near the bulk region, a stable electrical double-layer (EDL) structure is maintained, whereas in the deeper mixed region, persistent co-ion presence and significant disorder are observed. …”
