Numerical simulations of quiet Sun magnetic fields seeded by Biermann battery
, 2017 The magnetic fields of the quiet Sun cover at any time more than 90\% of its surface and their magnetic energy budget is crucial to explain the thermal structure of the solar atmosphere. One of the possible origins of these fields is due to the action of

Magnetic Flux Loss and Flux Transport in a Decaying Active Region [PDF]
, 2008 We estimate the temporal change of magnetic flux perpendicular to the solar surface in a decaying active region by using a time series of the spatial distribution of vector magnetic fields in the photosphere.

Advanced Functional Materials, EarlyView.Strong exciton‐photon coupling is achieved by integrating porphyrin ligand‐based MOF nanoparticles in optical cavities, as evidenced by pronounced polariton branch anticrossing. The porous nature of the resonator enables precise, reversible tuning via vapor pressure, unlocking unprecedented chemical‐environment controlled dynamic polaritonic platforms ...

Nonpotential Magnetic Fields with Emerging Magnetic Flux in a Solar-flare-productive Active Region
The Astrophysical JournalUsing a developing delta-class solar active region (NOAA 12673) as a case study, we analyzed the distribution of solar vector magnetic fields and derived the corresponding magnetic energy and helicity densities from vector magnetograms to characterize ...

Progress in the modeling of Earth and planetary internal magnetic fields
地球与行星物理论评A majority of the planets in the Solar System are characterized by intrinsic magnetic fields that co-rotate with these celestial bodies. With ongoing advances in human deep-space exploration, magnetic field models have been established for all known ...

Advanced Functional Materials, EarlyView.Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,
