Strontium isotope effect on Solid-Liquid extraction system using a polymer resin with 2.2.2-Cryptand anchor groups [PDF]
مجله علوم و فنون هستهای, 2020 The chemical isotope exchange with macrocyclic polyethers is one of the relatively new methods for isotope separation. These separations are based on the phenomenon of isotope effect, in which the kinetic and the stability of the complex formation ...

Isotope Effect in Thermal Conductivity of Polycrystalline CVD-Diamond: Experiment and Theory
Crystals, 2021 We measured the thermal conductivity κ(T) of polycrystalline diamond with natural (natC) and isotopically enriched (12C content up to 99.96 at.%) compositions over a broad temperature T range, from 5 to 410 K.

Anomalous isotope effect in BCS superconductors with two boson modes
New Journal of Physics, 2021 The isotope effect in the superconducting transition temperature is anomalous if the isotope coefficient α < 0 or α > 1/2. In this work, we show that such anomalous behaviors can naturally arise within the Bardeen–Cooper–Schrieffer framework if both ...

Solubility isotope effects in aqueous solutions of methane [PDF]
, 2002 The isotope effect on the Henry's law coefficients of methane in aqueous solution (H/D and C-12/C-13 substitution) are interpreted using the statistical mechanical theory of condensed phase isotope effects.

Analytical modelling of stable isotope fractionation of volatile organic compounds in the unsaturated zone [PDF]
, 2011 Analytical models were developed that simulate stable isotope ratios of volatile organic compounds (VOCs) near a point source contamination in the unsaturated zone. The models describe diffusive transport of VOCs, biodegradation and source ageing.

Inverse Iron Isotope Effect on the transition temperature of the (Ba,K)Fe2As2 superconductor [PDF]
, 2009 We report that (Ba,K)Fe2As2 superconductor (a transition temperature, Tc = 38 K) shows inverse Iron isotope effect (-0.18) (the sample including the larger atomic weight of Fe depicts higher Tc).

Iron isotope effect on the superconducting transition temperature and the crystal structure of FeSe_1-x [PDF]
, 2010 The Fe isotope effect (Fe-IE) on the transition temperature T_c and the crystal structure was studied in the Fe chalcogenide superconductor FeSe_1-x by means of magnetization and neutron powder diffraction (NPD).
