| 1 | 预变形结合人工时效对Al-Mg-Si合金力学性能的影响(英文)显示文摘研究预变形结合人工时效处理对AA6060铝合金强度和韧性的影响。对经过均匀化热处理和挤压加工的AA6060铝合金进行固溶处理,然后对材料实施0-10%的预变形并再进行时效处理或者在人工时效过程中进行同步变形。通过对不同时效处理后的合金的显微硬度和拉伸性能分析,发现预变形对材料的时效行为和力学性能有显著影响,它可以使合金的时效速度明显加快。比较预变形和同步变形对人工时效的影响发现,同步变形结合人工时效可以使该合金在更短的时间内得到更好的力学性能。对两种变形对时效行为的影响机理进行了探讨。 | Michal KOLAR Ketill Olav PEDERSEN Sverre GULBRANDSEN-DAHL Knut MARTHINSEN | 2012 | Transactions of Nonferrous Metals Society of China2012，22，8： | 10 |
| 2 | Al-Sc-Zr合金中析出相的形成及再结晶抑阻(英文)显示文摘通过冷硬铸造法制备Al-x%Sc-0.11%Zr合金(x=0,0.02,0.05,0.08,0.11,0.15),研究合金在475°C保温12h热处理条件下不同钪含量对Al3(Sc,Zr)析出的影响。研究发现,Al3(Sc,Zr)析出相的形核、析出和分布与钪含量密切相关。透射电子显微镜研究表明,随着钪含量的增加,析出相的平均半径减小,密度增大,分布变得越来越均匀。将90%冷轧样品在200-600°C的温度区间等温退火0.5h,再进行抗再结晶能力的研究。结果表明,未添加钪的合金的再结晶温度为250°C,而添加0.15%钪后形成的Al3(Sc,Zr)析出相使得再结晶温度升高到约600°C。 | 贾志宏 Jostein RφYSET Jan Ketil SOLBERG 刘庆 | 2012 | Transactions of Nonferrous Metals Society of China2012，22，8： | 9 |
| 3 | Methods for the extraction and RNA profiling of exosomes显示文摘AIM:To develop protocols for isolation of exosomes and characterization of their RNA content.METHODS:Exosomes were extracted from He La cell culture media and human blood serum using the Total exosome isolation(from cell culture media)reagent,and Total exosome isolation(from serum)reagent respectively.Identity and purity of the exosomes was confirmed by Nanosight?analysis,electron microscopy,and Western blots for CD63 marker.Exosomal RNA cargo was recovered with the Total exosome RNA and protein isolation kit.Finally,RNA was profiled using Bioanalyzer and quantitative reverse transcriptionpolymerase chain reaction(q RT-PCR)methodology.RESULTS:Here we describe a novel approach for robust and scalable isolation of exosomes from cell culture media and serum,with subsequent isolation and analysis of RNA residing within these vesicles.The isolation procedure is completed in a fraction of the time,compared to the current standard protocols utilizing ultracentrifugation,and allows to recover fully intact exosomes in higher yields.Exosomes were found tocontain a very diverse RNA cargo,primarily short sequences 20-200 nt(such as mi RNA and fragments of m RNA),however longer RNA species were detected as well,including full-length 18S and 28S r RNA.CONCLUSION:We have successfully developed a set of reagents and a workflow allowing fast and efficient extraction of exosomes,followed by isolation of RNA and its analysis by q RT-PCR and other techniques. | Emily Zeringer Mu Li Tim Barta Jeoffrey Schageman Ketil Winther Pedersen Axl Neurauter Susan Magdaleno Robert Setterquist Alexander V Vlassov | 2013 | World Journal of Methodology2013，3，1： | 5 |
| 4 | 快速凝固富钛Ti-V合金的微观组织和储氢性能(英文)显示文摘研究目的在于优化Ti0.8-0.9V0.2-0.1二元合金的相结构成分、微观组织和储氢性能。该合金主要用于从含有大量一氧化碳的高温气态混合物中吸收氢气。Ti0.8-0.9V0.2-0.1合金中的α-(HCP)和β-(BCC)相在纯氢气中基于氢化作用,形成单相FCC结构的氢化物,此过程与合金的化学成分无关。同步辐射X射线衍射的原位分析表明,在含有氢气和10%一氧化碳的混合气体中,只有β相转变成相应的氢化物。快速凝固(RS)处理细化了Ti0.8V0.2和Ti0.9V0.1合金的晶粒组织,而且,快速凝固处理增加了Ti0.9V0.1合金中的β相,其所占比例是普通熔铸条件下的两倍。扫描电子显微镜(SEM)分析表明,Ti0.9V0.1合金含有片状组织,层片的厚度约为300nm。热脱附谱(TDS)显示,微观组织的细化可以加快氢脱附的动力学过程。 | Suwarno SUWARNO Jan Ketil SOLBERG Jan Petter MAEHLEN Bente KROGH Bφrre Tore BφRRESEN Esther OCHOA-FERNANDEZ Erling RYTTER Mario WILLIAMS Roman DENYS Volodymyr A.YARTYS | 2012 | Transactions of Nonferrous Metals Society of China2012，22，8： | 2 |
