生物气溶胶在大气中扩散极易传播和发生各种流行疾病,也是生物武器投放的主要形式,实现生物气溶胶实时、远距离的探测显得尤为重要。构建了一台双波长荧光雷达用于大气中生物气溶胶的预警和识别。该雷达系统采用Nd∶YAG固体激光器作为激励光源,基频1 064nm、四倍频266nm作为工作波长。基于激光诱导荧光雷达探测原理,对红外波段的弹性散射信号和紫外波段诱导的荧光信号进行数值分析。结果显示,在探测误差小于10%的情况下,距离为1.0km时,单激光脉冲测量得到白天和夜晚细菌孢子的最小探测浓度分别为15 100个颗粒·L^(-1)和8 386个颗粒·L^(-1);当脉冲数累加到10 000时,白天和夜晚的细菌孢子最小探测浓度显著改善,分别为144个颗粒·L^(-1)和77个颗粒·L^(-1)。分析结果还表明,通过红外波段确定细菌孢子云团位置后,为了提高系统对细菌孢子的探测性能,可增加紫外激光脉冲数量,延长荧光信号采集时间。

Biomass conversion offers an efficient approach to alleviate the energy and environmental *** oxidation of 5-hydroxymethylfurfural(HMF) has attracted tremendous attention in the latest few years for the mild synthesis conditions and high conversion efficiency to obtain 2,5-furan dicarboxylic acid(FDCA), but there still remain problems such as limited yield, short cycle life,and ambiguous reaction mechanism. Despite many reviews highlighting a variety of electrocatalysts for electrochemical oxidation of HMF, a detailed discussion of the structural modulation of catalyst and the underlying catalytic mechanism is still lacking. We herein provide a comprehensive summary of the recent development of electrochemical oxidation of HMF to FDCA, particularly focusing on the mechanism studies as well as the advanced strategies developed to regulate the structure and optimize the performance of the electrocatalysts, including heterointerface construction, defect engineering,single-atom engineering, and in situ reconstruction. Experimental characterization techniques and theoretical calculation methods for mechanism and active site studies are elaborated, and challenges and future directions of electrochemical oxidation of HMF are also prospected. This review will provide guidance for designing advanced catalysts and deepening the understanding of the reaction mechanism beneath electrochemical oxidation of HMF to FDCA.
