Augmented plasmonic damping of dipole-resonant gold (Au) nanoparticles (NP) physicochemically bonded onto edges of tungsten disulfide (WS2) nanosheets, ostensibly due to hot electron injection, is quantified using electron energy loss spectroscopy (E

Electron probes can resolve bright and dark optical modes at subwavelength scales to distinguish localized effects, e.g., those of composition and geometry, via energy loss measurements. In this work, electron energy loss spectra of a metal nanospher

Physiological stress responses have been associated with lesser pregnancy rates in beef cattle. Alternative cattle restraint methods have been developed to reduce this negative effect. The objective was to determine if there was a difference in pregn
