Isotope Effect in the Superfluid Density of HTS Cuprates: Stripes, Pseudogap and Impurities

, 2005
Underdoped cuprates exhibit a normal-state pseudogap, and their spins and doped carriers tend to spatially separate into 1- or 2-D stripes. Some view these as central to superconductivity, others as peripheral and merely competing.

Heavy hydrogen in the stratosphere [PDF]

, 2003
We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40º N in October 2002. Strong deuterium enrichments of up to

Kinetic Isotope Effect

, 2014
Molecules with different isotopic compositions generally react with other molecules in the same manner, but their reaction rates show differences due to their mass differences and sometimes also due to the lower natural abundance of certain isotopes. For example, CO2 is heavier than CO2 by about 2.3 %, and the abundance ratio of CO2/ CO2 is about 1.1 %.

Role of APS reductase in biogeochemical sulfur isotope fractionation

Nature Communications, 2019
Changes in S-isotope ratios over time provide clues to understanding the co-evolution of Earth and its biosphere. Here the authors determine the isotope effect of the first reductive enzyme in the sulfate respiration pathway and reinterpret sedimentary S-

Density Functional Theory (DFT) and Quasi Harmonic Approximation (QHA) on Isotope effect of Methane Absorbed on Ag(111) Surface

Indonesian Journal of Applied Physics
We investigated the isotope effect of methane (CH4) on Ag(111) using van der Waals density functional and the quasi-harmonic approximation.In this study, we combined two methods to investigate the nuclear quantum effect in methane adsorption on an Ag(111)
