Abstract: In some embodiments, a system for measuring magnetic fields produced within a microscope comprising an electromagnetic lens includes a sensor support element configured to be mounted to a distal end of an elongated support member that is configured to be inserted into the microscope, and a magnetic field sensor supported by the sensor support element, the magnetic field sensor being configured to sense magnetic fields at a position within the electron microscope at which specimens are imaged during operation of the microscope.

Abstract: A variety of nanostructures are provided having a metal nanowire having a plurality of faces extending along a length of the nanowire, and a plurality of semiconductor nanorods forming two or more nanorod arrays, wherein each of the nanorod arrays is attached to a different surface of the nanowire. For example, in some embodiments, the nanostructure is a silver nanowire having a pentagonal cross section and five faces extending along the length of the nanowire, and metal oxide nanorods forming five nanorod arrays extending along each of the five faces of the silver nanowire. The nanostructures can demonstrate high temperature coefficients of resistance, and can be used in a variety of bolometric materials. In some embodiments, bolometric materials are provided including a plurality of the nanostructures deposited onto a surface of a substrate. Methods of making the nanostructures and bolometers are also provided.
