Solubility models of CH4, CO2, and noble gases and their geological applications
Solubility models for CH4, CO2, and noble gases are widely used in Earth Sciences, playing pivotal roles in the study of homogenization pressure of inclusions, paleoclimate variation, gas migration and accumulation, formation of helium-rich gas plays ...

New Experimental Tools to Use Noble Gases as Artificial Tracers for Groundwater Flow
Labeling groundwater by injecting an artificial tracer is a standard and widely used method to study groundwater flow systems. Noble gases dissolved in groundwater are potentially ideal artificial tracers, as they are not subject to biogeochemical ...

Pathway to cryogen free production of hyperpolarized Krypton-83 and Xenon-129. [PDF]
Hyperpolarized (hp) (129)Xe and hp (83)Kr for magnetic resonance imaging (MRI) are typically obtained through spin-exchange optical pumping (SEOP) in gas mixtures with dilute concentrations of the respective noble gas.

Computation-informed optimization of Ni(PyC)₂ functionalization for noble gas separations
Metal-organic frameworks (MOFs) are promising nanoporous materials for the adsorptive capture and separation of noble gases at room temperature. Among the numerous MOFs synthesized and tested for noble gas separations, Ni(PyC)₂ (PyC = pyridine-4 ...

A new Time-Of-Flight Mass Spectrometer (TOF-MS) for noble gas analysis [PDF]
Noble gas analysis in early solar system materials, which can provide valuable information about early solar system processes and timescales, are very challenging because of extremely low noble gas concentrations (ppt).

The Effect of Past Saturation Changes on Noble Gas Reconstructions of Mean Ocean Temperature
The ocean's immense ability to store and release heat on centennial to millennial time scales modulates the impacts of climate perturbations. To gain a better understanding of past variations in mean ocean temperature (MOT), a noble gas‐based proxy ...
