1The influence of the crystalline nature of nano-metal oxides on their antibacterial and toxicity properties显示文摘nano 金属氧化物的抗菌剂性质(ZnO, CuO ) 基于反应的氧种类(ROS ) 的形成。这个工作表明这些 nano 金属氧化物的抗菌剂性质强烈依赖于他们的水晶的结构。nanooxides 的抗菌剂活动对通常引起医院的感染的细菌的四种类型被测试。sonochemical 方法在纺织品上为 nanooxides 而且到他们的涂层的合成被使用不仅。与商业、 sonochemically 准备的 nano 金属氧化物涂的纺织品的抗菌剂性质被评估并且比较。毒性在人的肺房间和两栖动物胚胎上被评估,作为为吸入和水的毒物学的代表性的模型。sonochemically 准备的金属 nanooxides 比有一样的粒子尺寸范围的商业地可得到的金属氧化物是更好的抗菌剂。有更多的缺点和更少的组织结构的雏晶是更多,这被发现有毒。ROS 的形成被电子纺纱学习为两个的回声(ESR ) 大小 sonochemically 准备了并且 ZnO/CuO nanoparticles 的商业样品。激进的种类的生产的重要增加在更有缺点的、 sonochemically 准备的样品被发现,作为与商业的相比。因为 nanoparticle 缺点的调整影响了他们的毒性,设计更安全的 nano 抗菌剂的可能性被显示。liana Perelshtein Anat Lipovsky Nina Perkas Aharon Gedanken Elisa Moschini Paride Mantecca 2015Nano Research2015,8,2:8
2纳米金属镍的制备与磁性研究显示文摘采用微波polyol还原法成功地制备了单分散5~10nm镍球颗粒,由高分辨率电子显微镜(HRTEM)观察证实,5nm镍的颗粒面间距为0.2033nm,与文献报道的镍的FCC结构(100)面的0.2034nm比较吻合[JCPDS:4-850]。通过在不同温度下测量零场冷(ZFC)和场冷(FC,1600kA·m-1)所获样品的磁滞回线,发现纳米镍从铁磁性过渡到超顺磁性的相变温度Tpt=100K,在Tpt温度以上,磁滞回线都发生偏置。刘先松 陈鲁国 黄凯 周圣强 Udi Meridor Aviad Frydman Aharon Gedanken 2008稀有金属材料与工程2008,37,3:6
3Selective Cytotoxic Effect of ZnO Nanoparticles on Glioma Cells显示文摘In this study we examined the cytotoxic effect of ZnO nanoparticles on various human cancer and normal cells.We found that the ZnO nanoparticles exerted a cytotoxic effect on the human glioma cell lines A172,U87,LNZ308,LN18,and LN229,whereas no cytotoxic effect was observed on normal human astrocytes.Similarly,the ZnO nanoparticles induced cell death in breast and prostate cancer cell lines while no major effect was observed in the respective normal breast and prostate cell lines.Using the fl uorescent dye 2,7-dichlorofl uorescein diacetate,we found that treatment of the glioma cells with ZnO nanoparticles induced a large increase in the generation of reactive oxygen species(ROS)and treatment of the cells with N-acetyl cysteine decreased the cytotoxic effect of the ZnO nanoparticles.In contrast,a smaller effect on ROS generation was observed in the normal astrocytes.These results suggest that ZnO nanoparticles may be employed as a selective cytotoxic agent for the eradication of cancer cells.Stella Ostrovsky Gila Kazimirsky Aharon Gedanken Chaya Brodie 2009Nano Research2009,2,11:5
4微波辅助polyol法制备的纳米镍颗粒显示文摘采用微波辅助polyol还原法制备了单分散的纳米Ni颗粒。分别用X射线衍射(XRD)和透射电镜(TEM)观测样品的相结构和微观形貌,用振动样品磁强计(VSM)测试Ni颗粒的磁性。XRD显示样品为面心立方结构,TEM观察显示金属镍颗粒的形貌是理想的球型。当把反应温度提高到400℃,并且在实验过程中加入适量的PVP时,发现镍颗粒呈现出一种毛茸茸的多毛形态,这种分散均匀的单一态形貌类似于纳米头发的结构。同时,VSM测试结果表明球型纳米Ni颗粒具有典型的铁磁性。徐小兵 刘先松 Udi Meridor Aviad Frydman Aharon Gedanken 2008磁性材料及器件2008,39,6:4
5Microbial community structure and nitrogenase gene diversity of sediment from a deep-sea hydrothermal vent field on the Southwest Indian Ridge显示文摘A sediment sample was collected from a deep-sea hydrothermal vent field located at a depth of 2 951 m on the Southwest Indian Ridge. Phylogenetic analyses were performed on the prokaryotic community using polymerase chain reaction(PCR) amplification of the 16 S rRNA and nifH genes. Within the Archaea, the dominant clones were from marine benthic group E(MBGE) and marine group I(MGI) belonging to the phyla Euryarchaeota and Thaumarchaeota, respectively. More than half of the bacterial clones belonged to the Proteobacteria, and most fell within the Gammaproteobacteria. No epsilonproteobacterial sequence was observed. Additional phyla were detected including the Actinobacteria, Bacteroidetes, Planctomycetes, Acidobacteria, Nitrospirae, Chloroflexi, Chlorobi, Chlamydiae, Verrucomicrobia, and candidate divisions OD1, OP11, WS3 and TM6, confirming their existence in hydrothermal vent environments. The detection of nifH gene suggests that biological nitrogen fixation may occur in the hydrothermal vent field of the Southwest Indian Ridge. Phylogenetic analysis indicated that only Clusters I and III NifH were present. This is consistent with the phylogenetic analysis of the microbial 16 S rRNA genes, indicating that Bacteria play the main role in nitrogen fixation in this hydrothermal vent environment.WU Yuehong CAO Yi WANG Chunsheng WU Min AHARON Oren XU Xuewei 2014Acta Oceanologica Sinica2014,33,10:3
6单分散Ni球制备及Ni/NiO的磁性研究显示文摘使用微波辅助Poly方法制备了直径范围在100nm~180nm单分散的Ni球,用磁力显微镜(MFM)测其磁结构。进一步对Ni球表面氧化获得了高度球化的NicoreNiOshell结构,采用XRD,TEM,XPS和EDAX对其进行了测量分析,并用VSM和SQUID进一步讨论了铁磁/反铁磁的界面耦合效应。同时,估算了磁性交换偏置耦合场与颗粒尺寸的关系。刘先松 周圣强 黄凯 Udi Meridor Aviad Frydman Aharon Gedanken 2006稀有金属材料与工程2006,35,9:2
