Abstract: Systems and methods of detecting a vortex made by a travelling object is disclosed. In some configurations, a graphic recognition algorithm and vortex similarity engine are used to determine whether a visual media file captured by a media collector contains a vortex. The vortex similarity engine may be configured to determine or identify certain properties about the travelling object based on the travelling object vortex. In some configurations, a computer may trigger an alert if a travelling object vortex is not expected to be in the visual media file.

The thermoset may be degraded by treatment with a solution of a fluoride salt in an organic solvent.

Abstract: Heterostructures include a layer of a two-dimensional material placed on a multiferroic layer. An ordered array of differing polarization domains in the multiferroic layer produces corresponding domains having differing properties in the two-dimensional material. When the multiferroic layer is ferroelectric, the ferroelectric polarization domains in the layer produce local electric fields that penetrate the two-dimensional material. The local electric fields modulate the charge carriers and carrier density on a nanometer length scale, resulting in the formation of lateral p-n or p-i-n junctions, and variations thereof appropriate for device functions.
