Anomali Total Electron Content (TEC) Di Ionosfer Sebagai Prekursor Gempa Bumi Di Sumatra

Jurnal Fisika Unand, 2020
Telah dilakukan penelitian anomali Total Electron Content melalui data sinyal radio frekuensi-ganda GPS. Penelitian 5 buah gempa bumi di barat Sumatera menggunakan data SuGAr dan IGS telah dilakukan untuk mengetahui adanya prekursor gempa bumi melalui analisis anomali TEC. Terdapat 5 gempa yang dianalisis dengan magnitudo 5 hingga 9 SR.

Study on the Three-Dimensional Evolution of Ionospheric Disturbances in China During the Geomagnetic Storm on December 1, 2023

Atmosphere
On 1 December 2023, a strong geomagnetic storm was triggered by an interplanetary shock caused by a coronal mass ejection (CME). This study used data from 193 Global Navigation Satellite System (GNSS) observation stations in China to study the three ...

GPS total electron content (TEC) for ionospheric observation

GPS total electron content (TEC) for ionospheric observation
[ABSTRACT]Total electron content (TEC) investigation is one of the powerful tools in ionsopheric study. Several case studies and statistical studies on storms, tsunami, earthquakes, and so on have been performed. To understand the mechanism, monitoring of three-dimensional distributions of ionospheric electron density is effective.

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

Advanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

Advanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Analysis of the altitudinal structure of Storm-enhanced density using Total Electron Content data of space-borne and ground-based GPS receivers

Antarctic Record, 2013
The altitudinal structure of Storm-enhanced density (SED) was studied using the Total Electron Content (TEC) data of the GPS receiver on the Gravity Recovery and Climate Experiment (GRACE) satellite and the ground-based GPS receivers.

GPS Total Electron Content (TEC) Prediction at Ionosphere Layer over the Equatorial Region [PDF]

, 2010
In this chapter we have presented methods for processing TEC which utilize different techniques. Two scenario of obtaining TEC were studied such as TEC dual frequency and TEC Map. First, for TEC Dual Frequency, GPS carrier phase derived TEC provides a smooth but relative measurement of ionospheric TEC, while code derived TEC provides a noisy but ...

Short‐Wavelength Infrared Imaging with Organic Photodetectors Based on Non‐Fullerene Acceptors with Detection above 1200 nm

Advanced Materials, EarlyView.
Solution‐processed organic photodetectors (OPDs) based on two novel low band gap non‐fullerene acceptors BZIC‐2F and BZIC‐2Cl, when blended with common polymer donor P3HT, extend detection range beyond 1200 nm with superior performance, rivaling costly inorganic sensors and past literature.

Freeform Fabrication of Layered Halide Perovskite Nanowire Heterojunctions

Advanced Materials, EarlyView.
‘All‐at‐once’ freeform fabrication of layered perovskite nanowire heterojunctions is realized by 3D printing employing meniscus‐guided crystallization. The integration of nanoscale additive manufacturing with layered halide perovskites will provide a versatile platform to freely design and realize highly stable perovskite‐based optoelectronic ...
