Abstract ：
利用核壳型的CdSe@CdS量子点作为发光物质，并用壳聚糖（CS）、类石墨烯氮化碳（gC_3N_4）与CdSe@CdS量子点合成了CdSe@CdS/CS/gC_3N_4复合物，将该复合物修饰至玻碳电极（GCE）表面，将适配体（Apt）的互补DNA链（cDNA）通过化学反应连接到量子点上，Apt与cDNA发生杂交反应而被修饰至电极表面。将辣根过氧化物酶（HRP）固定到该修饰电极表面，构建了检测卡那霉素（Kana）的电化学发光（ECL）适配体传感器。通过生物催化沉淀（BCP）方法实现Kana的检测，溶液中无Kana时，在H_2O_2的存在下，修饰在电极上的HRP可以催化氧化4-氯-1-萘酚（4-CN），在电极表面产生不导电的苯并-4-氯己二烯酮沉淀，导致电化学发光信号明显降低。溶液中存在Kana时，Kana会与Apt特异性结合，部分dsDNA解旋，导致部分HRP从电极表面脱落，BCP反应减弱，导致ECL信号增强，实现目标物质的特异性检测。计算适配体传感器在Kana溶液中的ECL强度（I）与传感器在空白溶液中的ECL强度（I_0）的差值ΔI (I-I_0)，并以此作为响应信号。结果显示，ΔI与Kana浓度的对数值在1.0×10~(-8)～1.0×10~(-4) g/L范围呈良好的线性关系，检出限为5 ng/L。该传感器在实际样品测定中具有较好的应用前景。

本文将多壁碳纳米管(MWCNT)修饰到玻碳电极(GCE)界面,并基于臭氧(O3)与靛蓝三磺酸钾(ITS)的灵敏反应,间接实现了水中O3的定量测定.利用扫描电镜和循环伏安法对该修饰电极进行了形貌和电化学性质表征.在最优实验条件下,溶液中ITS的方波伏安(SWV)峰电流在2.0× 10-7～6.4×10-5 mol·L-1浓度范围内随ITS的浓度增大而呈线性增强,检测限为5×10-8mol·L-1.当体系中存在O3时,ITS的SWV峰电流随臭氧浓度的增加而减小,往ITS溶液中加入臭氧溶液前后峰电流减小的差值与O3浓度的对数值在5.0×10-9～1.0×10 5 mol·L-1范围内呈线性关系,检测限为1×10-9 mol·L-1,本方法具有灵敏度高,操作简便,重现性好的优点.

Abstract ：
Air pollution has a serious fallout on human health, and the influences of the different urban morphological characteristics on air pollutants cannot be ignored. In this study, the relationship between urban morphology and air quality (wind speed, CO, and PM2.5) in residential neighborhoods at the meso-microscale was investigated. The changes in the microclimate and pollutant diffusion distribution in the neighborhood under diverse weather conditions were simulated by Computational Fluid Dynamics (CFD). This study identified five key urban morphological parameters (Building Density, Average Building Height, Standard Deviation of Building Height, Mean Building Volume, and Degree of Enclosure) which significantly impacted the diffusion and distribution of pollutants in the neighborhood. The findings of this study suggested that three specific strategies (e.g. volume of a single building should be reduced, DE should be increased) and one comprehensive strategy (the width and height of the single building should be reduced while the number of single buildings should be increased) could be illustrated as an optimized approach of urban planning to relief the air pollution. The result of the combined effects could provide a reference for mitigating air pollution in sustainable urban environments. © 2021

Abstract ：
The sodium-treated sepiolite (NaSep)-supported rare earth oxide (RE/NaSep; RE = La, Eu, Dy, and Tm) samples were prepared using the rotary evaporation method. Physicochemical properties of these materials were characterized by XRD, SEM, BET, FTIR, XPS, H-2-TPR, NH3-TPD, and in situ DRIFTS, and their catalytic activities for formaldehyde (HCHO) (2000 ppm) oxidation were evaluated. The results show that loading of the rare earth oxide on NaSep improved its catalytic performance. Among all the samples, Eu/NaSep performed the best, and complete HCHO conversion was achieved at a temperature of 150 degrees C and a gas hourly space velocity of 240,000 mL/(g h); a good catalytic activity was still maintained after 45 h of stability test. The catalytic oxidation mechanism of HCHO was studied using the in situ DRIFTS technique. As a result, the effective and stable catalytic performance of the Eu/NaSep sample was mainly due to the presence of hydroxyl groups on the sepiolite surface and the doped rare earth oxides, which contributed to its high performance. HCHO oxidation underwent via the steps of HCHO + O-2 -> HCOO- + OH- -> H2O + CO2. It is concluded that the optimal catalytic activity of Eu/NaSep was associated with the highest O-ads/O-latt atomic ratio, the largest amount of hydroxyl groups, the highest acidity, and the best reducibility. The present work may provide new insights into the application in the removal of high-concentration HCHO over the rare earth oxides supported on natural low-cost clays.

Abstract ：
In this study, a novel electrochemiluminescence (ECL) biosensor based on a CdSe@CdS quantum dot (QD)-functionalized MoS2-modified electrode was developed for the sensitive detection of mercury ions. Polycationic poly(diallyldimethylammonium chloride) (PDDA) and negatively charged QDs were adsorbed on the surface of MoS2, in sequence, to form the QD-PDDA-MoS2 composites, which were employed as matrices for immobilizing thymine-rich DNA sequences (DNA(1)). The gold nanoparticles (AuNPs) were combined with another type of thymine-rich DNA sequences (DNA(2)) and glucose oxidase (GOD) to prepare the GOD-AuNP-DNA(2) conjugates. The composites were characterized via UV-visible absorption spectroscopy, fluorescence and transmission electron microscopy. A thymine-Hg2+-thymine complex was formed through Hg2+ mismatching with DNA(1) and DNA(2). GOD was, therefore, modified onto the electrode surface. GOD catalyzed the reduction of dissolved oxygen by glucose to produce hydrogen peroxide, which was a co-reactant of the QDs. The electrochemiluminescence signal of the biosensor increased linearly with the increase in the Hg2+ concentration over the range from 1.0 x 10(-12) to 1.0 x 10(-6) M with a detection limit of 1 x 10(-13) M. The reproducibility, stability and specificity of the biosensor was also studied. The biosensor was used to determine Hg2+ in a real water sample and satisfactory results were obtained.

Abstract ：
In this paper, CdS quantum dots (QDs) were synthesized. Positively charged poly(diallyldimethylammonium chloride) (PDDA) and negatively charged CdS quantum dots were sequentially adsorbed on the surface of graphene oxide (GO). The nano-luminescent materials GO-QDs were prepared and characterized by UV-Vis absorption spectroscopy, fluorescence spectroscopy and transmission electron microscopy. The GO-QDs were then modified on the surface of glassy carbon electrode (GCE). Chloramphenicol aptamer (apt) of 5'-end modified biotin hybridized with the aptamer complementary strand (cDNA) of 5'-end modified amino group into double-stranded DNA (dsDNA). The double-stranded DNA was bonded onto the surface of GO-QDs modified electrode. When the electrode was incubated with streptavidin - labeled horseradish peroxidase (SA-HRP), the biotin modified at the end of the chloramphenicol aptatner can specifically bind directly to the streptavidin labeled HRP. Therefore, HRP was bonded to the surface of the electrode. Hydrogen peroxide was used as the co-reactant of the QDs. HRP can thereby consume hydrogen peroxide and can weaken the electrochemiluminescence intensity. Chloramphenicol in solution can specifically bind to the aptamer to form a composite and to unwind the dsDNA. Then the composite was detached from the surface of the electrode. HRP also left the electrode surface along with the aptamer, so that the electrochemiluminescence signal was significantly enhanced. The electrochemiluminescence intensity of the sensor showed a linear correlation with the logarithm of chloramphenicol concentration. The linear range was 1.0 x 10(-12)-1.0 x 10(-7) M, the detection limit is 0.5 pM. The reproducibility, stability and specificity of the sensor were also studied. The sensor was used for the determination of chloramphenicol in samples and satisfactory results were obtained. (C) 2020 Elsevier B.V. All rights reserved.
