- First example of carbon quantum dot synthesis via Continuous Hydrothermal Flow Synthesis. Produced from biomass precursor, citric acid, and N-doped using ammonia to give blue-luminescent N-doped carbon quantum dots. Their rarely observed excitation independent optical properties, and stability, demonstrated high selectivity and sensitivity as nano-sensors for carcinogenic Cr(VI) over a broad pH range. This approach has greater efficiency and simplicity in manufacturing via a more environmentally benign process, with higher selectivity, sensitivity and fast response in tuning product outcomes than traditional batch processes. RSC's "Editor’s Choice: Hydrothermal Materials Synthesis" for 2020. Contributed to experimental design and development, analysis, and writing.
