The Separation of Isotopes [PDF]

open access: yesNature, 1920
IN view of recent work by Ashton, the practical aspect of this problem again becomes important. Considerable weight must be given to the conception of Lindemann and Ashton (Phil. Mag., May, 1919) that isotopes are capable of chemical as well as of physical separation.

Application of the Grey Wolf Optimization Algorithm to Separate Middle Components in Multicomponent Mixtures [PDF]

open access: yesJournal of Nuclear Research and Applications, 2023
In this paper, optimization of a system of square cascades for separation of middle isotopes is introduced, and the optimal square cascade for use in this system is presented. In this case, 130Xe which is a middle isotope, is presented as an example. The

Investigation the effect of M* and α0 on the separation of 4th and 8th isotopes of tellurium in a Q model cascade [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2022
One of the crucial parameters in designing the Q model cascade for the multi-component systems is the M* parameter. In this research, a code called MOTACAS has been developed to design a Q cascade, using the optimal value of the M* parameter.

Photoluminescence Induced in Mineral Oil by Ionizing Radiation

open access: yesLubricants, 2023
We have studied photoluminescence (PL) properties of vacuum pump mineral oil as a function of the type and intensity of ionizing radiation exposure. The mineral oil has a simple aliphatic structure, which possesses no chromophore in the traditional sense.

Centrifugal Separation of Boron Isotopes Using Boron Trichloride as Processing Gas

open access: yesJournal of Isotopes, 2018
Stable isotopes had been widely used in the industrial production, health care, fundamental physics research, and so on. Natural boron has two stable isotopes: 10B (19.9%) and 11B(80.1%).

Study on Specific Carbon Isotope Fractionation of n-Alkanes during Column Chromatography Separation-Molecular Sieve Complexation Adsorption

open access: yesYankuang ceshi, 2021
BACKGROUND Before analyzing the carbon isotopes of n-alkanes by gas chromatography-gas isotope mass spectrometry (GC-IRMS), it is necessary to pre-separate and enrich n-alkanes and isoparaffins in saturated hydrocarbon samples. Whether the carbon isotope
