In this study, we present a facile method to prepare thiocyanato-functionalized porous silica nanospheres. Thiocyanato functionalized silica shells were coated on positively charged cetyltrimethylammonium bromide （CTAB） micelles via hydrolysis and condensation of （3-thiocyanatopropyl）triethoxysilane （TCPTES）, the CTAB cores were removed subsequently to form thiocyanato-functionalized porous sil- ica nanospheres. We demonstrate that the contents of the thiocyanato groups within the functionalized porous silica nanosphere frameworks gradually diminished as a function ofhydrothermal treatment time at 100~C until complete removal, confirmed by TGA and FTIR spectra. The data indicate that extended operation at relatively elevated temperatures may lead to the decomposition of the thiocyanato functional groups. In addition, at a lower CTAB concentration （0.0009 M）, non-porous thiocyanato functionalized sil- ica nanospheres were formed. However, increasing the CrAB concentration to 0.01 M resulted in porous nanospheres inferring that a CTAB concentration threshold is needed to form thiocyanato-functionalized porous silica nanospheres.

Climate change and anthropogenic activities are expected to impact the environmental behaviors and fates of persistent organic pollutants(POPs), however, quantitative studies on these combined factors are scarce. In this study, dichlorodiphenyltrichloroethane(DDTs), polycyclic aromatic hydrocarbons(PAHs), and polychlorinated biphenyls(PCBs)were used as examples to identify how and when those factors may be related to the deposition of POPs in the sediment of Lake Chaohu, China, using generalized additive models(GAMs). Three historical trends of DDT, PAH, and PCB deposition were delineated in a dated sediment core encompassing ~100 years of historical record: a steady state or gradually increasing stage, a rapidly increasing stage, and a declining stage. The GAM results showed that aquatic total phosphorus(TP) concentrations and regional GDP(anthropogenic factors) were dominant contributors to POP accumulation rates in the lake sediment. The fitted relationships between air temperature and sedimentary DDT and PAH concentrations were linear and negative, while a positive linear relationship was found for PCBs, suggesting that Lake Chaohu may have become a net source for DDTs and PAHs, and a sink for PCBs, under a progressively warming climate.

Sediment core samples collected from Lake Chaohu were analyzed for 15 priority polycyclic aromatic hydrocarbons（PAHs）to assess the spatial and temporal distributions of the PAHs during lacustrine sedimentary processes and regional economic development.Assessing the PAH sedimentary records over an approximately 100-year time span,we identified two stages in the PAH inputs and sources（before the 1970 s and after the 1970s）in the eastern lake region near a village,whereas three stages（before the 1950 s,1950s–1990s and after the1990s）were identified in the western lake region near urban and industrial areas.Rapid increases in the PAH depositional fluxes occurred during the second stage due to increased human activities in the Lake Chaohu basin.The composition and isomeric ratios of the PAHs revealed that pyrolysis is the main source of PAHs in this lake.Strong positive relationships between PAH concentration and the total organic carbon concentration,sediment grain size（〈 4 μm）,as well as the local population and Gross Domestic Product indicated that the sedimentary conditions impact the depositional characteristics of the PAHs;simultaneously,socioeconomic activities,such as energy consumption and the levels of urban industrialization and civilization,affect both the composition and abundance of the PAHs.

混合超级电容器具有高比功率、高比能量等优点,是一种极具潜力的储能装置,但其常用的溶液电解质或有机电解质分别存在电化学窗口较窄和易燃的缺点,限制了其应用范围。离子液体具有不可燃性、宽电化学窗口等特点,成为混合超级电容器用电解质的理想选择。本文回顾了近年来离子液体在混合超级电容器中的应用,介绍了离子液体单独作为电解质、混合电解质组分、固态电解质组分和电极组分在混合超级电容器中的应用,指出降低离子液体吸湿性与成本是未来应用于混合超级电容器方向上的研究重点。近年来由于对混合超级电容器与非对称超级电容器定义的理解出现偏差,造成了表述上的混乱,因此尝试对两者的概念进行了解释和区分。

矿用电缆受煤矿恶劣环境影响,容易发生绝缘劣化、护套受损等情况,传统的矿用电缆检测多采用低压脉冲法、局放法等离线诊断方式,操作复杂,准确度低,难以满足现代煤矿生产需求。而现有基于谐波的电缆故障诊断方法存在检测装置笨重、检测精确低、难以在煤矿应用等问题。针对上述问题,提出一种基于电流谐波特征的矿用电缆劣化监测与故障诊断方法。提取电缆中高次谐波含量信息作为故障特征向量,对特征向量进行归一化处理后导入极限梯度提升树(XGBoost)模型,结合已知电缆故障劣化度数据,形成训练样本集,训练XGBoost模型,最后通过构建的XGBoost模型对电缆劣化度进行实时监测和故障诊断。仿真结果表明:针对电缆不同部位提取的高次谐波向量的相对能量有明显不同,表明提取的高次谐波向量可表征电缆不同部位的运行状态;XGBoost模型的拟合优度参数R2高达0.93,且误差较小。案例分析结果验证了基于电流谐波特征的矿用电缆劣化监测与故障诊断方法可对矿用电缆运行状态及劣化故障进行实时、准确的监测和诊断。
