The present invention relates to a monochromator device. The monochromator device includes a first radiofrequency cavity positioned to receive an output beam from an electron source. A second radiofrequency cavity is positioned to receive the output beam from the first radiofrequency cavity. The first radiofrequency cavity and the second radiofrequency cavity are configured to, in combination, in combination, correct one or more energy deviations in time and space of the output beam.

Monochromator device and methods of use thereof

Embodiments provide a nanoparticle and a method for preparing the nanoparticle, as well as a membrane that includes the nanoparticle and a fuel cell that includes the membrane. The method comprises a thermal treatment method that provides from a nanoparticle comprising a structurally disordered material the nanoparticle comprising: (1) a structurally ordered core comprising a first material; and (2) a shell surrounding and further structurally aligned with the structurally ordered core and comprising a second material different from the first material. Particularly desirable is a nanoparticle comprising a PtCo@Pt/C structurally ordered core-shell composition supported upon a carbon support.
