碳量子点作为一种新型的碳纳米材料[1]，具有光致发光、电化学发光、低细胞毒性、生物相容性、催化活性等优良性能，并广泛用于生物成像、传感器、光电器件、药物载体等方面。本课题采用微波消解法[2]，分别以柠檬酸和三羟甲基氨基甲烷为碳源和氮源，合成氮掺杂的，具有高荧光量子产率的碳量子点。通过紫外可见分光光度计、荧光光谱仪、透射电镜(TEM)、原子力显微镜(AFM)对合成的碳量子点进行表征，结果表明该碳量子点单分散性能好，稳定性高，荧光性能好。基于叶酸能使碳量子的荧光发生淬灭，建立了叶酸定量检测的方法。该方法具有快速、灵敏的特点。

Water-in-diesel乳液是一种以水为分散相,柴油为连续相的油包水(W/O)型乳液。相比于普通柴油,water-in-diesel乳液有以下显著优势：(1)水乳滴的存在可导致微爆作用,使柴油燃烧更加充分；(2)水的存在能有效减少燃烧尾气中氮氧化物(Nox)、黑烟和可吸入颗粒物(PM)的排放。然而,water-in-diesel乳液的不稳定性和外观很大程度上限制了其发展和应用。本项目由商用表
