The investigation of quasi-separatrix layers in solar magnetic fields

, 2011
The structure of the magnetic field is often an important factor in many energetic processes in the solar corona. To determine the topology of the magnetic field features such as null points, separatrix surfaces, and separators must be found.

The influence of the magnetic field on running penumbral waves in the solar chromosphere

, 2013
We use images of high spatial and temporal resolution, obtained using both ground- and space-based instrumentation, to investigate the role magnetic field inclination angles play in the propagation characteristics of running penumbral waves in the solar ...

Surprisingly Large Doppler Shifts in Hinode EUV Imaging Spectrometer (EIS) Solar Spectra Resulting from an Inconspicuous Small-scale Jet in Extreme-ultraviolet Images

The Astrophysical Journal Letters
Strong EUV line shifts in solar spectra are generally indicative of highly dynamic and explosive events that are easily detected in comparable-wavelength EUV images, with the strongest such line shifts (several 100 km s ^−1 ) occurring in solar flares ...

Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

Advanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

Topological structure of the magnetic solar corona

, 2007
The solar corona is a highly complex and active plasma environment, containing many exotic phenomena such as solar flares, coronal mass ejections, prominences, coronal loops, and bright points.

The Evolution of Photospheric Magnetic Fields at the Footpoints of Reconnected Structures in the Solar Atmosphere

The Astrophysical Journal
Magnetic reconnection is believed to play an important role in the release and conversion of energy among magnetized plasma systems. So far, we have been unable to understand under what conditions magnetic reconnection can take place.

The Evolution of the Solar Magnetic Field [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractThe almost stately evolution of the global heliospheric magnetic field pattern during most of the solar cycle belies the intense dynamic interplay of photospheric and coronal flux concentrations on scales both large and small. The statistical characteristics of emerging bipoles and active regions lead to development of systematic magnetic ...

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 ...

Development and application of a global magnetic field evolution model for the solar corona

, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Preliminary Discussion on the Current Sheet

The Astrophysical Journal
The current sheet is a characteristic structure of magnetic energy dissipation during the magnetic reconnection process. So far, the width and depth of the current sheet are still indefinite.
