Perpetual Atomics, QSA Global produce Am fuel for nuclear space power
U.K.-based Perpetual Atomics and U.S.-based QSA Global claim to have achieved a major step forward in processing americium dioxide to fuel radioisotope power systems used in space missions. Using an industrially scalable process, the companies said they have turned americium into stable, large-scale ceramic pellets that can be directly integrated into sealed sources for radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs).

Equivalence between a proposed Lorentz invariant and the standard Lorentz transformed description of the radiative scattering kernel is established for arbitrary distributions of moving electrons, contraindicating the suggestion that additional, or extraneous, terms appear in the invariant description.
