21. He headed the group located at Columbia University that developed isotope separation using gaseous diffusion. 22. At Institute A, Thiessen became leader for developing techniques for manufacturing porous barriers for isotope separation . 23. Next, that undergoes isotope separation through the process of gaseous diffusion, or in a gas centrifuge. 24. He played an important role in delaying funding for a Special Isotope Separation project in Idaho. 25. A second method of laser separation is known as molecular laser isotope separation ( MLIS ). 26. In Institute A, Thiessen became leader for developing techniques for manufacturing porous barriers for isotope separation . 27. Oliphant inspired Lawrence to convert his old cyclotron into a giant mass spectrometer for isotope separation . 28. Fuchs and Peierls did some important work together, which included a fundamental paper about isotope separation . 29. While in England he discovered a means of isotope separation known as the Szilard Chalmers effect. 30. Research into how uranium isotope separation ( uranium enrichment ) could be achieved assumed enormous importance.
