Scientists probe ferroelectric domains in curved free-standing superlattices

By growing superlattices consisting of ferroelectric and non-ferroelectric transition metal oxides and releasing them from their underlying substrates, researchers explore polarization patterns in curved geometries. Complex transition-metal oxides are often sensitive to strain and may display very different properties if their lattice is compressed or extended. This is especially true of ferroelectric materials, such as

Correlative imaging of a single neuronal cell opens the door to profound multi-perspective sub-cellular examinations

Scientists combined two nano-imaging techniques that stand at opposite ends of the electromagnetic spectrum to demonstrate the benefits of correlative imaging to examine individual neurons from different perspectives. To showcase this, they studied the molecular structures of amyloid proteins and investigated the role metal ions may play in the development of Alzheimer’s Disease at a
