Abstract

Abstract: Invited for this month's cover is the group of Michael Ruck and Thomas Doert at the Technische Universität Dresden (Germany). The cover picture 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. Read the full text of their Full Paper at 10.1002/open.202000236 . Abstract : "… In comparison to solvothermal syntheses in steel autoclaves, the reaction progress in microwave‐assisted synthesis can be controlled in situ, and reaction parameters can be adjusted accordingly… Find out more about the story behind the front cover research at 10.1002/open.202000236 .
