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.

Probing Ionic Liquid Aqueous Solutions Using Temperature of Maximum Density Isotope Effects
Molecules, 2013 This work is a new development of an extensive research program that is investigating for the first time shifts in the temperature of maximum density (TMD) of aqueous solutions caused by ionic liquid solutes.

A Spectroscopic Overview of Intramolecular Hydrogen Bonds of NH…O,S,N Type
Molecules, 2021 Intramolecular NH…O,S,N interactions in non-tautomeric systems are reviewed in a broad range of compounds covering a variety of NH donors and hydrogen bond acceptors. 1H chemical shifts of NH donors are good tools to study intramolecular hydrogen bonding.

Scientific Reports, 2021 Investigation of isotope effects on superconducting transition temperature (T c) is one of the useful methods to examine whether electron–phonon interaction is essential for pairing mechanisms. The layered BiCh2-based (Ch: S, Se) superconductor family is

Molecules, 2013 Much of our understanding of the mechanisms of enzyme-catalyzed reactions is based on steady-state kinetic studies. Experimentally, this approach depends solely on the measurement of rates of free product appearance (d[P]/dt), a mechanistically and ...

Isotope shift of the ferromagnetic transition temperature in itinerant ferromagnets [PDF]
Physics Letters A381, 737-741 (2017), 2016 We present a theory of the isotope effect of the Curie temperature $T_{\rm c}$ in itinerant ferromagnets. The isotope effect in ferromagnets occurs via the electron-phonon vertex correction and the effective attractive interaction mediated by the electron-phonon interaction.

Isotope effect on the Casimir force [PDF]
arXiv, 2022 Isotopic dependence of the Casimir force is key to probing new physics and pushing novel technologies at the micro and nanoscale, but is largely unexplored. In 2002, an isotope effect of 10^(-4) was estimated for metals -- orders of magnitude beyond the experimental resolution.
