Clathration of Volatiles in the Solar Nebula and Implications for the Origin of Titan's atmosphere [PDF]

open access: yes, 2008
We describe a scenario of Titan's formation matching the constraints imposed by its current atmospheric composition. Assuming that the abundances of all elements, including oxygen, are solar in the outer nebula, we show that the icy planetesimals were ...

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.

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 ...

Simulation and Optimization of Ultra-High Purity Krypton/Xenon Cryogenic Distillation System Based on HYSYS

open access: yesShanghai Jiaotong Daxue xuebao, 2021
To meet the requirements of the low background and high sensitivity of the large-scale dark-matter detector PandaX-4T, nKr/nXe≤1×10 -13 (n is the amount of substance) is required. The ultra-high purity krypton/xenon cryogenic distillation

A numerical study of the double-glazed solar air heater (DG-SAH) performance using optimized gas-filled interspaces

open access: yesCase Studies in Thermal Engineering, 2022
The reduction of energy losses and destroyed exergy requires the optimization of the double-glazing space. The poor thermophysical characteristics of the air are a limiting factor in the attenuation of heat loss through the double-glazing of the solar ...
