The Progress of Cryogenics and Isotopes Separation is an annualy journal and reflects the scientific activity of the research staff from the National R&D Institute for Cryogenics and Isotopic Technologies. Researchers from outside the institute can also publish their papers within the available space. The main topic areas of the journal are: Stable Isotopes Physics, Technologies and Applications; Cryogenic Technologies and Equipments; Materials Science and Engineering; Nuclear Power – fission and fusion; Hydrogen and Fuel Cells; Environmental and Life Quality; Laboratory Analysis Methods; Agriculture and Food Safety. The papers published in Progress of Cryogenics and Isotopes Separation should present novel results and have either theoretical significance or practical utility or both. They may be presented in the form of full articles or short communications.
