Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design
Advanced Materials Technologies, EarlyView.This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Atomic‐Scale Insights into Yttrium‐Induced Grain Boundary Structure Modification in Al2O3
Advanced Science, EarlyView.Using advanced STEM characterization combined with NNP‐based MCMD calculations, it is revealed that Y segregation at ∑13 Al2O3 GB involves not only simple substitution of Y for Al atoms but also structural adaptation with a change in GB atomic density, leading to minimized excess volume and lowest GB energy.
