AbstractCryo-transmission electron microscopy (cryo-EM) of frozen hydrated specimens is an efficient method for the structural analysis of purified biological molecules. However, cryo-EM and cryo-electron tomography are limited by the low signal-to-noise ratio (SNR) of recorded images, making detection of smaller particles challenging.

AbstractAs high-quality single-crystal materials used in electronic devices approach the microscale and nanoscale, charge-transport phenomena in these devices result in inhomogeneous spatial signatures with strong implications for observable material properties. These signatures include spatially varying dissipation, which affects thermal management strategies in devices, and interface resistance between different materials, and are essential for the functional control of devices.
