3-D Topology Optimization of Spatially Averaged Surface-Enhanced Raman Devices
Published 2024“…Representative applications include light-emitting diodes, thermal emitters, and Raman sensing. Previous efforts in full-scale topology optimization for Surface Enhanced Raman Sensing (SERS) have predominantly focused on single particle emissions or two-dimensional systems, which are impractical for actual fabrication. …”

Ultrahigh plateau-capacity sodium storage by plugging open pores
Published 2025“…In particular, a large portion of the capacity (490 mAh g-1) lies below the plateau of 0.25 V, which originates from the pore-filling mechanism as revealed by in situ Raman. This study provides a straightforward method to modulate the pore structure of carbon materials, and an energy-efficient (900 °C) synthesis for HC compared to traditional high-temperature routes (e.g., ≈1300-2000 °C).…”
