Atomic engineering
Atomic engineering is an engineering discipline concerned with the scale of materials engineering at the atomic level, which is one order of magnitude lower than nanoengineering. Atom manipulation is a part of atomic engineering, but the main difference lies in the fact that atomic engineering focuses on creating atomic features usable at ambient conditions. Atomic engineering may be considered a superset of nuclear engineering, which is the branch of engineering that seeks "to harness the energy released from nuclear reactions" via "the application of nuclear energy in a variety of settings, including nuclear power plants, submarine propulsion systems, medical diagnostic equipment such as MRI machines, food production, nuclear weapons and radioactive-waste disposal facilities."
