Observation of O+ 4P-4D0 lines in proton aurora over Svalbard [PDF]

open access: yes, 2004
Spectra of a proton aurora event show lines of O+ 4P-4D0 multiplet (4639–4696 Å) enhanced relative to the N2 +1N(0,2) compared to normal electron aurora. Conjugate satellite particle measurements are used as input to electron and proton transport models,

Energetic electron precipitation into the atmosphere

open access: yes, 2020
This chapter provides an overview of the impact of energetic electron precipitation from the aurora and the radiation belts on the composition, radiative balance, and dynamics of the Earth's atmosphere, from the lower thermosphere down to the surface. The primary processes related to atmospheric ionization and subsequent collision reactions that lead ...

Investigation of Thermo‐Chemical Processes in Commercial MgO‐C Refractory Bricks With and Without MgO‐C Recyclate at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...

A change of mesospheric ozone content under electron precipitation influence [PDF]

open access: yes
The simulation model of a change of O, O2 and O3 oxygen component content at the heights 50 to 140 km under electron precipitation influence is presented. Parameters of the air mass vertical transfer are introduced into the model.

Thermophysical Properties of the Desulphurization Slags With Various CaS and CaO/Al2O3 Ratio

open access: yesAdvanced Engineering Materials, EarlyView.
This article investigates how CaS content and the CaO/Al2O3 ratio influence the thermophysical properties of desulphurization slags. Using experimental measurements and thermodynamic simulations, this study reveals complex effects on viscosity, surface tension, and density, providing new insight into slag structure and phase behavior under ...

High temporal resolution observations of auroral electron density using superthermal electron enhancement of Langmuir waves

open access: yesGeophysical Research Letters, 2016
We report high temporal resolution auroral electron precipitation observations using the Sondrestrom incoherent scatter radar. The observations make use of the superthermal electron enhancement of Langmuir waves, which is shown to give accurate ...

Correlative electron microscopy of discontinuous precipitation

open access: yesArchives of Civil and Mechanical Engineering
AbstractThis paper presents a comprehensive study on discontinuous precipitation (DP) in Al-22 at.% Zn alloy, leveraging the correlative and synergic effects of advanced microscopy and modelling techniques. The study is structured into three pivotal steps: in-situ scanning electron microscopy combined with an energy backscattered diffraction analysis ...
