Mini Abstract: To clarify the mechanism of coercive field change in Fe-Si-B-P-Cu nanocrystalline soft magnetic alloys, we observed the microstructure of heat-treated (Fe76Si9B10P5)99.5Cu0.5 alloy and investigated the correlation between the microstructure and magnetic properties. As a result, we observed the pinning of magnetic domain walls by Fe3B precipitates.

Correlative light and volume electron microscopy to study brain development

Shuichi Hayashi, Nobuhiko Ohno, Graham Knott and Zoltán Molnár

Mini Abstract: In this mini-review, we overview how volume EM and vCLEM have contributed to studying developmental processes of the brain. We also give examples for the combinatorial usage of genetic tools with vCLEM that will further enhance our understanding of regulatory mechanisms underlying brain development.
