Composition formulas of solid-solution alloys derived from chemical-short-range orders

Scientific Reports, 2022
Solid solutions are the basis for most industrial alloys. However, the relationships between their characteristic short-range orders and chemical compositions have not been established.

Electron beam calibration constants

Japanese Journal of Radiological Technology, 1978
Electron treatment beam calibration constants are tabulated in a convenient form for mean incident electron energies, Eo, of 6 to 21 MeV; and practical reanges, Rp, of 2.75 to 10.53 cm of water. Values of mean electron energy at depth Ed, chamber radius correction factors (Kp), and CE factors may be readily obtained from this chart.

Escherichia coli Cells Exposed to Lethal Doses of Electron Beam Irradiation Retain Their Ability to Propagate Bacteriophages and Are Metabolically Active

Frontiers in Microbiology, 2018
Reports in the literature suggest that bacteria exposed to lethal doses of ionizing radiation, i.e., electron beams, are unable to replicate yet they remain metabolically active.
