Effect of Added Ni Nanoparticles on the Microstructure and Mechanical Properties of Sn58Bi/Cu Solder Joints under Thermal Shock Conditions

open access: yesAdvanced Electronic Materials, EarlyView.
This article concludes that the microstructure as well as grain coarsening is suppressed and the growth of IMC layer is promoted in Sn58Bi/Cu solder joints versus Sn58Bi‐0.6 Ni/Cu solder joints after 1200 thermal shock experiments, while the mechanical properties of the solder joints are improved.

A Universal Doping Strategy for Boosting Luminescence Efficiency of Blue‐Emitting Hybrid Zn Halides as Ultrastable and Underwater Scintillators

open access: yesAggregate, EarlyView.
A Pb2+‐doping method is demonstrated to be a universal strategy to realize near‐unity photoluminescence quantum yield and high water‐resistance stability for a family of blue‐emitting zero‐dimensional Zn2+‐based halides through increasing the exciton binding energy and carrier density.
