Scientists have been coaxing nano-s

Scientists have been coaxing nano-sized cubes of magnetite (Fe3O4) into larger, more complex structures like helices without using a template by exposing them to a magnetic field.
A team led by Rafal Klajn at the Weizmann Institute of Science in Israel found that by varying the density of the cubes and the size and direction of the magnetic field they can control the kind of structure the cubes self-assemble into, which depends on the interplay between intermolecular forces and magnetic interactions. Under an increasing magnetic field the nanocubes line up to make a ‘belt’, while under a constant magnetic field at high density they curl round and form a helix. Single helices tend to clump together to make double helices (like the rope-like structure shown above) or even triple helices.

Although at the moment there is no obvious use for the structures, the team say they could have interesting magnetic properties. They are now exploring the effects of using other magnetic nanomaterials, such as nickel or iron nanoparticles, and decorating the nanocube surfaces with functional ligands to see what other shapes can be made.

科学家们已经一直不让他们接触到磁场中使用模板哄着纳米级多维数据集中的磁铁矿 (Fe3O4) 成更大、 更复杂的结构,像螺旋.
由以色列魏茨曼科学研究所在佩服 Klajn 领导的小组发现通过改变密度与多维数据集的大小和方向的磁场他们可以控制的结构的多维数据集自组装成那种,这取决于分子间力和磁场的相互作用之间的相互作用。不断增加的磁场作用下微晶排队,使 '带',而在高密度恒定磁场下他们卷曲轮并形成一种螺旋结构。单螺旋倾向于簇集在一起,使双股螺旋 (就像上面所示的绳状结构) 或甚至三重

虽然此刻是没有明显的结构,用螺旋。团队说他们可能会有有趣的磁性质。他们目前正在探索使用其他磁性纳米材料,如镍或铁纳米颗粒和装饰 nanocube 表面与功能性的配体,看看能有什么其他形状的影响了。

科学家们一直在哄磁铁矿(Fe3O4的)的纳米立方体成更大,更复杂的结构,如螺旋,而不使用模板,通过他们接触到磁场。
为首的拉法尔Klajn在魏茨曼科学研究所的以色列研究小组发现,通过改变立方体的磁场的密度,大小和方向能控制的那种结构的立方体自组装成,这取决于分子间力和磁相互作用之间的相互作用。在越来越磁场的纳米立方体排队做'带',而一个恒定的磁场在高密度下,他们蜷缩轮,并形成螺旋。单螺旋倾向于聚集在一起,使双螺旋(如上面所示的绳状结构),甚至三螺旋。虽然目前存在的结构没有明显的用途,球队说他们能有有趣的磁特性。他们正在探索使用其它磁性纳米材料,如镍或铁纳米粒子,装潢的纳米立方体的表面功能性配体,看看有什么其他的形状可以做成的影响。

科学家们已经把纳米立方体的磁铁矿(Fe3O4)到更大的,更复杂的结构,如螺旋不使用模板通过将它们暴露于磁场。
在以色列魏茨曼科学研究所的拉法尔klajn LED的一个研究小组发现,通过不同的多维数据集的密度和磁场的大小和方向可以控制类结构的自组装成的立方体,这取决于分子间力和磁相互作用之间的相互作用。增加磁场下纳米线进行“带”,而在一个恒定的磁场在高密度它们卷圆,形成螺旋。单螺旋倾向于聚集在一起,使双螺旋结构(如绳状结构,如上图所示)甚至三重螺旋。

虽然目前的结构没有明显的使用,该小组说,他们可能有有趣的磁学性质。他们正在探索使用其他磁性纳米材料的影响,例如镍或铁纳米粒子,并与功能性配体装饰立方体表面看其他形状可。
