我们首次证明磁场可以作为独立参数来加速液体反应系统中的柯肯达尔效应。以硅基纳米球为模型，证明磁场可以在相对较低的反应温度下有效缩短柯肯达尔效应过程的时间。 1T磁场下5h后所得产品的中空结构与无磁场24h后所得产品相同。
We show for the first time that a magnetic field can act as an independent parameter to accelerate the Kirkendall effect in a liquid reaction system. By taking silicon-based nanospheres as a model, it was demonstrated that a magnetic field could efficiently reduce the time of the Kirkendall effect processes at relatively low reaction temperatures. The hollow structure of the product obtained after 5 h under a magnetic field of 1 T is the same as that obtained after 24 h without a magnetic field.
