Latest Patents

One of Angell's latest patents is titled "Multicomponent alloyed plasmonic photocatalysis." This invention provides improved photocatalysis for chemical reactions involving hydrogen in two-component plasmon-catalyst nanoparticles. The main idea of this work is to configure the optical illumination of the nano-articles to suppress the formation of an undesirable hydride phase in the nanoparticles. This concept is broadly applicable to any chemical reaction involving hydrogen, with specific examples including acetylene hydrogenation to produce ethylene, carbon dioxide reduction, and ammonia synthesis.

Another notable patent is "Sub-wavelength Raman imaging with combined optical and electron excitation." This invention enhances stimulated Raman spectroscopy by replacing the Stokes (or anti-Stokes) optical source with a localized electromagnetic emitter that is excited with a non-electromagnetic excitation. Such a localized emitter can serve as an efficient Stokes (or anti-Stokes) source for stimulated Raman spectroscopy, providing deep sub-wavelength spatial resolution. In a preferred embodiment, an electron beam from an electron microscope is used to excite the localized emitter, allowing for combined Raman imaging and electron microscopy that are inherently registered with each other.
