| 1 | 无烟煤微生物成气中间代谢产物组成及其转化显示文摘研究了煤生物成气过程中中间产物的变化规律与成气过程的相互关系。以10 kg沁水盆地山西寺河矿的无烟煤为底物,以寺河矿区煤层气井口出水为菌源,进行了煤生物成气模拟实验,利用气相色谱-质谱联用对不同成气阶段发酵液中间产物进行了分析。实验发现煤生物成气有2个主要的产气周期,芳香环、杂环化合物和苯衍生物在反应初期转化为VFA等,发生在第1个产气周期;而长链烷烃的生成有2个高峰期,分别对应2个产气周期。根据煤生物成气模拟实验中间代谢产物的实验结果,进一步选取乙酸钠、丙酸钠、丁酸钠、己酸为底物,仍以同一煤层气井口出水为菌源,进行产气实验模拟,结果显示乙酸、丙酸、丁酸可以产气,而己酸则对成气呈现抑制作用。以底物计算甲烷产生效率为丁酸>丙酸≈乙酸,丁酸约为乙酸和丙酸的4倍;而以碳数计算时甲烷产生效率则为丁酸>乙酸>丙酸,丁酸约为乙酸的2倍,说明不同的有机酸产甲烷时可能存在有机酸碳数奇偶性的差异。以上结果表明,VFA和长链烷烃在煤生物成气中发挥着重要的作用,而有关煤生物成气中VFA和长链烷烃的生成和转化以及其对成气的影响尚需进一步研究。 | 陈林勇 王保玉 邰超 关嘉栋 赵晗 王美林 韩作颖 | 2016 | 煤炭学报2016，41，9： | 21 |

| 4 | Preparation of monolayer-assembled fluorescent film and its sensing performances to hidden nitroaromatic explosives显示文摘Pyrene was chemically assembled on a glass plate surface in a monolayer manner via spacers con-taining triethylenetetramine (TETA) subunits. It has been demonstrated that the fluorescence emission of the film is sensitive to the presence of trace amount of nitroaromatic compound (NAC) vapors. As discovered in the present work, the response selectivity of the pyrene-functionalized film depends on the length of the spacer, the vapor pressure of a given NAC, and the quencher size. The film shows faster response to those quenchers which have higher vapor pressure and smaller size. Compared to the film with shorter spacers, the present film with longer flexible spacers shows a slower response to the NACs, but higher selectivity to the quencher size. Additionally, the detection limits to common ex-plosives in vapor phase, 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT), are 7.14×10-12 and 5.49×10-11 g·mL-1, respectively. Further examinations indicated that the sensing process is fully re-versible, and the vapors of those common interference such as benzene, toluene, ethanol, and perfume have little effect upon the sensing performances of the film. | LI HuiHui LU FengTing ZHANG ShuJuan HE Gang FANG Yu | 2008 | Chinese Science Bulletin2008，53，11： | 4 |

| 8 | Subchronic toxicological effects of aquatic nitrobenzene on Medaka and Chinese rare minnow显示文摘Based on the simulative exposure experiments of nitrobenzene to two small experimental fishes, Medaka (Oryzias latipes) and Chinese Rare Minnow (Gobiocypris rarus), it was found that nitrobenzene could decrease in a linear way in the static aquatic system. Both fishes could accumulate dose-related levels of nitrobenzene quickly and eliminate the compound rapidly when they were transferred to clean water. The Chinese rare minnow showed more sensitivity to the acute toxicity exposure of nitrobenzene than Medaka. Typical molecular biomarkers in oxidative defense system including superoxide dismu- tase (SOD), catalase (CAT) showed the chemical induced alterations. The changes of acetylcholi- nesterase (AChE) activities indicated that nitrobenzene might affect the normal neural function. Nitro- benzene exposure could also lead to obvious damaging effects on the target organs, such as gill and liver by hitopathological studies. | ZHOU QunFang1, FU JianJie1,2, MENG HaiZhen1,2, ZHU XueYan1,2, JIANG GuiBin1, ZHANG JianBin1, LIU JieMin2 & SHI GuoQing2 1 State Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China 2 Department of Chemistry, School of Applied Science, University of Science and Technology Beijing, Beijing 100083, China | 2007 | Science China Chemistry2007，50，5： | 2 |
