Estimating the absolute total electron content based on single-frequency satellite radio navigation GPS/GLONASS data

Solar-Terrestrial Physics, 2017
We present a new technique for estimating the absolute vertical and slant total electron content (TEC). The estimation is based on single-frequency joint phase and pseudorange GPS/GLONASS measurements at single stations.

Evaluation of geomagnetic storm effects on the GPS derived Total Electron Content (TEC)

Journal of Physics: Conference Series, 2015
The geomagnetic storm represents the most outstanding example of solar wind- magnetospheric interaction, which causes global disturbances in the geomagnetic field as well as triggers ionospheric disturbances. We study the behaviour of ionospheric Total Electron Content (TEC) during the geomagnetic storms.

Interfacial Electronic Restructuring in MAPbBr3/rGO Hybrids Enabling Improved Charge Extraction for Efficient Photodetection

Advanced Materials Interfaces, EarlyView.
MAPbBr3/rGO hybrids exhibit interfacial electronic restructuring that enhances charge extraction in photodetectors. The incorporation of rGO modifies the surface chemical environment, enhances electron‐dominated transport, and suppresses performance degradation, resulting in higher responsivity, detectivity, and photostability than in pristine MAPbBr3 ...

Can we detect X/M/C-class solar flares from global navigation satellite system data?

Results in Physics, 2019
Based on the total electron content (TEC) data from global navigation satellite system (GNSS), we analyzed 224 classified solar flares (SFs) occurred in 2014–2017. We suggest an algorithm for SF automatic detection.

Van der Waals Chromium Telluride Thin Films Prepared by Hybrid Pulsed Laser Deposition With Tunable Magnetism

Advanced Materials Interfaces, EarlyView.
Epitaxial Cr(1+δ)Te2 thin films were synthesized via hybrid Pulsed Laser Deposition (PLD) that combined Molecular Beam Epitaxy (MBE) techniques with PLD. Control of the Cr intercalation, δ, enabled modulation of magnetic anisotropy, Curie temperature, and transport properties.
