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.

Mapping the East African Ionosphere Using Ground-based GPS TEC Measurements [PDF]

Journal of Astronomy and Space Sciences, 2016
The East African ionosphere (3°S–18°N, 32°E–50°E) was mapped using Total Electron Content (TEC) measurements from ground-based GPS receivers situated at Asmara, Mekelle, Bahir Dar, Robe, Arbaminch, and Nairobi.

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

Advanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

The Error of Global Ionospheric Map‐TEC During Equatorial Plasma Bubble Event in the High Solar Activity Year

Space Weather
In this study, the error of total electron content (TEC) derived from the global ionospheric map (GIM) (GIM‐TEC) during equatorial plasma bubble (EPB) event is investigated for the first time.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Plasmaspheric effects on one way satellite timing signals [PDF]

The effects of the ionospheric retardation of satellite-emitted timing signals was presented. The retardation at the navigation frequencies, which is proportional to the total ionospheric electron content (TEC), was determined by Faraday polarization ...

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption

Advanced Materials, EarlyView.
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This

Automatic Data Downloading Program (DDP) in Determining Regional Ionosphere Model

Journal of New Results in Science, 2018
GNSS (Global Navigation Satellite System) signals passthrough various layers of the atmosphere until they reach the receiver on theEarth. One of these layers is the Ionosphere. Ionosphere may be defined as theatmospheric layer that consists of the gasses
