The Discovery of Argon [PDF]

open access: bronzeNature, 1904
IN your translation of Prof. Mendeleeff's interesting paper on the chemical elements (November 17, p. 94) I see that he attributes the discovery of argon and its congeners to Ramsay. Am I not right in believing that it was Lord Rayleigh who discovered argon, and that it was he who gave that impulse to chemistry which Sir William Ramsay has carried ...

Direct dating of overprinting fluid systems in the Martabe epithermal gold deposit using highly retentive alunite [PDF]

open access: yesGeochronology, 2023
The Martabe gold deposits in Sumatra formed in a shallow crustal epithermal environment associated with intermediate mafic intrusions adjacent to an active right-lateral wrench system. Gas/fluid temperatures reached 200–350 ∘C.

40Ar/39Ar geochronology of Burdigalian paleobotanical localities in the central Paratethys (south Slovakia)

open access: yesGeologica Acta, 2021
The Lipovany and Mučín paleobotanical localities contain important floral associations within the tuff horizons, which were used for determination of subtropical to tropical climatic conditions during the Early Miocene.

Discovery of argon in air-hydrate crystals in a deep ice core using scanning electron microscopy and energy-dispersive X-ray spectroscopy

open access: yesJournal of Glaciology, 2022
Tiny samples of ancient atmosphere in air bubbles within ice cores contain argon (Ar), which can be used to reconstruct past temperature changes. At a sufficient depth, the air bubbles are compressed by the overburden pressure under low temperature and ...

Analysis of argon isotope separation by low temperature adsorption [PDF]

open access: yesMATEC Web of Conferences, 2020
In this work, the estimated calculated values of the critical parameters of argon isotopes 36Ar, 38Ar, 40Ar and the corresponding values of the constants of the Van der Waals, Redlich-Kwong and Peng-Robinson equations of state are obtained.

Are Protein Cavities and Pockets Commonly Used by Redox Active Signalling Molecules?

open access: yesPlants, 2023
It has been well known for a long time that inert gases, such as xenon (Xe), have significant biological effects. As these atoms are extremely unlikely to partake in direct chemical reactions with biomolecules such as proteins, lipids, and nucleic acids,

Noble gas and neuroprotection: From bench to bedside

open access: yesFrontiers in Pharmacology, 2022
In recent years, inert gases such as helium, argon, and xenon have gained considerable attention for their medical value. Noble gases present an intriguing scientific paradox: although extremely chemically inert, they display a remarkable spectrum of ...

Ionization waves in nanosecond pulsed atmospheric pressure plasma jets in argon

open access: yesHigh Voltage, 2021
Typical ionization waves (IWs) are observed during the propagation of nanosecond pulsed atmospheric pressure plasma jets (APPJs) with argon flow, combining both the measurement of the axial electric field (Ez) and the temporal resolved optical imaging ...
