On the interference of Kr during carbon isotope analysis of methane using continuous-flow combustion–isotope ratio mass spectrometry [PDF]

open access: yesAtmospheric Measurement Techniques, 2013
Stable carbon isotope analysis of methane (δ13C of CH4) on atmospheric samples is one key method to constrain the current and past atmospheric CH4 budget.

Runaway electrons during subnanosecond breakdowns in high-pressure gases

open access: yesHigh Voltage, 2016
The parameters of runaway electrons produced in nanosecond high-voltage discharges in different gases (air, nitrogen, sulphur hexafluoride, krypton, argon, methane, neon, hydrogen, helium) at atmospheric and higher pressure were studied.

High-Pressure Reactivity of Kr and F2—Stabilization of Krypton in the +4 Oxidation State

open access: yesCrystals, 2017
Since the synthesis of the first krypton compound, several other Kr-bearing connections have been obtained. However, in all of them krypton adopts the +2 oxidation state, in contrast to xenon which forms numerous compounds with an oxidation state as high

The world of krypton revisited [PDF]

open access: yesNature Chemistry, 2016
Matic Lozinsek and Gary J. Schrobilgen consider krypton — namesake of Superman's home planet — its superoxidant compounds, and their roles in coaxing elements into their highest oxidation states.

The possibility for gamma and UV radiation detection based on electrical breakdown time delay measurement in krypton and xenon filled diodes [PDF]

open access: yesNuclear Technology and Radiation Protection, 2021
The paper presents results of electrical breakdown time delay mean value t¯d as a function of relaxation time τ (memory curve) for krypton and xenon-filled diodes at 270 Pa pressure.

Influence of the characteristics of the working fluids of an electric jet engine on the energy and design parameters of a space vehicle during launch into geostationary orbit [PDF]

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
This paper examines the use of electric propulsion engines using krypton as the propellant for launching payloads into geostationary orbit. Key aspects of using electric propulsion engines using xenon and krypton as propellants are presented.

Automated Sampling System for Monitoring 85Kr in Air

open access: yesAtmosphere, 2023
Radioactive krypton-85 (85Kr) gas, a chemically inert and non-proliferation indicator, is derived from fission products. Its detection relies on the Budesamt für Strahlenschutz–Institute of Atmospheric Radioactivity (BfS-IAR) method, which necessitated ...

Secondary scintillation yield in pure krypton

open access: yesPhysics Letters B, 2022
The absolute secondary scintillation yield is of paramount importance for modelling dual-phase or high-pressure gas detectors, to be used in contemporary and in future rare event detection experiments.

Technical Note: Calibration device for the krypton hygrometer KH20 [PDF]

open access: yesAtmospheric Measurement Techniques, 2012
A calibration device for krypton hygrometers (KH20, Campbell Scientific, Inc.) with variable path length is presented. This unit allows for in-situ calibrations of the krypton hygrometer, which is typically not very stable over time, during measuring ...
