Tracer Applications of Noble Gas Radionuclides in the Geosciences
The noble gas radionuclides, including 81Kr (half-life = 229,000 yr), 85Kr (11 yr), and 39Ar (269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes.

A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Research Progress on CO Oxidation with Supported Noble Metal Catalysts
The excessive emission of carbon monoxide (CO) from steel sintering flue gas poses a significant threat to regional air quality and human health. This necessitates the development of effective CO treatment technologies for sintering flue gas. Among these,

Synthesis of Xenon and Iron/Nickel intermetallic compounds at Earth's core thermodynamic conditions
Although Xe is known to form stable compounds with strong electronegative elements, evidence on the formation of stable compounds with electropositive elements, such as Fe and Ni, was missing until very recently.

By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

Leading Interaction Components in the Structure and Reactivity of Noble Gases Compounds
The nature, strength, range and role of the bonds in adducts of noble gas atoms with both neutral and ionic partners have been investigated by exploiting a fine-tuned integrated phenomenological–theoretical approach.

Noble gases as tracers of the origin and evolution of the Martian atmosphere and the degassing history of the planet [PDF]
Noble gas analysis of Martian samples can provide answers to a number of crucial questions. Some of the most obvious benefits will be in Martian chronology, using techniques that have been applied to lunar samples. However, these are by no means the only

Accretion and Early History of Planetesimals and Planets: The Noble Gas Record [PDF]
Some of the distinct noble gas "components” in meteorites represent a record of processes during and even before solar system formation. This record is difficult to interpret.
