Isotope and Spin Effects Induced by Compression of Paramagnetic Molecules

Physchem, 2022
The zero-point energies (ZPEs) of paramagnetic molecules, free and compressed in a C59N paramagnetic cage, were computed. The excess of energy acquired by molecules under compression depended on the deuterium and tritium isotopes which ranged from 6–8 ...

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.

Isotope Effect of Host Material on Device Stability of Thermally Activated Delayed Fluorescence Organic Light‐Emitting Diodes

Small Science, 2021
Organic light‐emitting diodes (OLEDs) exhibiting thermally activated delayed fluorescence (TADF) have attracted great interest because of their excellent exciton harvesting ability in electroluminescence (EL).

The JET hybrid scenario in Deuterium, Tritium and Deuterium-Tritium

Nuclear Fusion, 2023
The JET hybrid scenario has been developed from low plasma current carbon wall discharges to the record-breaking Deuterium-Tritium plasmas obtained in 2021 with the ITER-like Be/W wall.

Equilibrium and kinetic isotope effects in heterogeneous catalysis: A density functional theory perspective

Catalysis Communications, 2023
Isotopes are indispensable tools for elucidating catalytic reaction mechanisms. Yet, computational isotopic studies in heterogeneous catalysis remain scarce, especially when compared with other subfields of chemistry.

The effects of diagenesis on lithium isotope ratios of shallow marine carbonates

American Journal of Science, 2020
In this study, we present new data on the δ7Li values and Li/(Ca+Mg) ratios of carbonate cores from the Great Bahama Bank (Clino, Unda), a deep water core off of the bank top (ODP Leg 166 Site 1007), and the coralline Key Largo Limestone.
