Biocompatible magnetic nanoparticles (MNPs) are of potential applications in biological separation,but the development of an appropriate technique including a production process for higher efficient separation and the subsequent immunoassay for lower level still represent a great challenge [1].Interestingly,even though carboxydextran-coated MNPs have been manufactured commercially (under the trade name of Rosovist [2]) as a MRI contrast agent,to the best of our knowledge,a thorough investigation on the amenability of carboxydextran-coated MNPs for facile and regenerable bioassay/bioseparation has not been conducted.

现代城市对高品质城市森林的景观效益需求愈加提升，而我国目前的城市森林大多仅作为城市基础绿化而出现。为营建符合时代需求的城市森林，本文从风景园林的视角，提出以塑造植物群落空间和构建功能设施体系两个层面对城市森林进行营建，并最终将这两层面耦合成为完整的景观体系，并以北京市十八里店地块作为案例进行实践检验，以期深化人们对城市森林营造的理解，进而创造更加自然美好的新时代中国风景园林。
刻槽管是一种性能卓越的吸能元件.本文提出一种新的理论模型以预测刻槽管在轴向冲击荷载下的动力响应.通过与实验结果的对比,验证了理论模型的可靠性,并得到以下结论:(1)刻槽管在冲击荷载下的响应由两个相构成;(2)第一相时间短暂,刻槽管的横向惯性占主导作用.在碰撞后的瞬间,系统的初始动能会随撞击物质量的减小而减小,表现出刻槽管的惯性敏感性;(3)在第二相中,刻槽管的横向惯性效应随角位移的增加而迅速降低,
为了考察边框刚度对屈曲约束钢板剪力墙抗震性能的影响,本文将带边框普通钢板剪力墙和屈曲约束钢板剪力墙作为研究对象,采用ABAQUS非线性有限元分析软件,计算边框刚度对构件受力性能的变化.计算结果表明,在水平往复荷载作用下,带边框屈曲约束钢板剪力墙的滞回曲线饱满,等效粘滞阻尼系数较大,边框柱与边框梁对侧向刚度、承载力与塑性耗能均有一定贡献.在1/50层间位移角时,屈曲约束钢板剪力墙边框柱与边框梁的内凹
