| 1 | Relationship between fluorescence characteristics and molecular weight distribution of natural dissolved organic matter in Lake Hongfeng and Lake Baihua,China显示文摘Dissolved organic matter (DOM) is one of the most interesting and difficult problems in recent years due to its important functions in the ecological and environmental system and the complexity of its chemical composition and structure. It is well ac- cepted that fluorescence characteristics and mo- lecular weight distribution are two important pa- rameters in the DOM characterization. However, the relationship between them is still unknown. In this study, fluorescence and molecular weight distribution of DOM in Lake Hongfeng, Lake Baihua and their rivers, and their relationship were investigated using the combination of fluorescence spectroscopy and high-performance size exclusion chromatography (HPSEC) with on-line UV absorbance and fluores- cence detectors. The results show that there were two obvious humic-like fluorescence peaks (Peaks A and B) in DOM from lake water. But there was an- other obvious protein-like fluorescence peak (Peak C) in DOM from river water. The humic-like fluorescence material consisted of DOM fraction with smaller mo- lecular weight, ranging from 1.0 to 3.0 kDa, while the protein-like fluorescence material mainly consisted of DOM fraction with MW larger than 2.0 kDa. The cal- culation of MW using HPSEC was related to the UV absorbance wavelength chosen. | YUE Lanxiu WU Fengchang LiU Congqiang LI Wen FU Pingqing BAI Yingchen WANG Liying YIN Zuoying Lü Zhicheng | 2006 | Chinese Science Bulletin2006，51，1： | 9 |
| 2 | Effects of rapid quenching on structure and cycle stability of La-Mg-Ni-Co type hydrogen storage alloy显示文摘In order to improve the cycle stability of La-Mg-Ni-Co type alloy electrode, rapid quenching technology was employed. The effects of rapid quenching on the microstructure and cycle stability of the alloy were investigated. The obtained results show that the La2Mg(Ni0.85Co0.15)9M0.1 (M=B, Cr) alloy electrodes are composed of (La, Mg)Ni3 phase, LaNi5 phase and a small amount of the LaNi2 phase. A trace of the Ni2B phase exists in the as-cast MB alloy, and the Ni2B phase in the alloy nearly disappears after rapid quenching. Rapid quenching technology can slightly improve the cycling life of the alloy. When the quenching rate increases from 0 m·s-1 (As-cast is defined as quenching rate of 0 m·s-1) to 30 m·s-1, the cycle lives of the MB, MCr alloys enhance from 86 and 87 cycles to 106 and 119 cycles, respectively. On the other hand, the average capacity decay rates of the MB, MCr alloys decrease from 1.7172 and 1.7178 mAh·g-1·cycle-1 to 1.5751 and 1.3060 mAh·g-1·cycle-1 after 86 charge-discharges cycling, respectively. | DONG Xiaoping Lü Fanxiu ZHANG Yanghuan YANG Liying FENG Meng WANG Xinlin | 2006 | Rare Metals2006，25，z1： | 4 |
| 3 | Autophagy as new emerging cellular effect of nanomaterials显示文摘The biosafety issue of nanoscale materials is getting more and more attention with their increasing manufacture and application.In the research of cellular effects and underlying mechanisms related to toxicity of nanomaterials,most emphasis were placed on processes such as apoptosis,metabolic inhibition and oxidative stress.Recent evidence suggests that autophagy is part of the biological effects by nanomaterials and various kinds of nanomaterials are capable of disturbing the autophagic process.This review will highlight the importance of autophagy as an emerging mechanism of nanomaterial toxicity and the implication in the therapy of autophagy-related diseases.We summarize current research status of interaction between nanomaterials and autophagic pathways.It is of note that nanomaterials can either induce or block autophagy,which result in similar phenotype but completely different biological consequence.It is therefore important to perform comprehensive analysis of the whole autophagic flux in the future research. | ZHONG WenYing Lü Min LIU LiYing SUN JinLi ZHONG ZengTao ZHAO Yun SONG HaiYun | 2013 | Chinese Science Bulletin2013，58，33： | 3 |
