The Front Cover shows the transformation of a Bi‐Ni core‐shell particle into a homogenous intermetallic BiNi particle. To understand the mechanism for the BiNi formation in the polyol process, various methods such as X‐ray and electron diffraction, HR‐TEM, mass spectrometry and FT‐IR spectroscopy were employed. In a microwave‐assisted one‐pot synthesis at first Bi‐particles emerge by reduction of a Bi‐salt. The reduction of the Ni‐salt most likely occurs on the surface of these particles, followed by a complete encasement of the Bi‐core (blue) with a shell of Ni‐particles (green). As the reaction continues, the Ni‐atoms diffuse into the Bi‐core until the homogeneous BiNi particle is attained. More information can be found in the Full Paper by Matthias Smuda et al.

封面：微波辅助多元醇工艺中Bi-Ni相形成的机理（ChemistryOpen 11/2020）

封面显示了Bi-Ni核-壳粒子转变为均质的金属间BiNi粒子。为了了解多元醇过程中BiNi形成的机理，采用了各种方法，例如X射线和电子衍射，HR-TEM，质谱和FT-IR光谱。在微波辅助的单锅合成中，首先通过还原双盐会出现双粒子。镍盐的还原很可能发生在这些颗粒的表面，然后用镍颗粒的壳（绿色）完全包裹双核（蓝色）。随着反应的继续，Ni原子扩散到Bi-core中，直到获得均匀的BiNi粒子。更多信息可以在Matthias Smuda等人的“全文”中找到。
