Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

Advanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Evidence for globally coherent variability in solar magnetic flux emergence

The Astrophysical Journal, 1980
We examine the large-scale spatial and temporal variations in the emergence of X-ray bright points on the sun, in order to study the global properties of magnetic flux emergence. Major variations in the rate of flux emergence are observed at all solar latitudes, on a time scale of 3-5 months.

Radiation‐Matter Interaction in Chemical Vapor Deposition‐Grown Two‐Dimensional Tungsten Disulfide

Advanced Materials Interfaces, EarlyView.
Gamma irradiation tunes the magnetic properties of CVD‐grown WS2 material. Moderate irradiation doses induce low‐temperature ferromagnetic‐like behavior, whereas higher doses suppress the magnetic response because of increased defect formation. These findings provide insight into defect‐mediated magnetism in 2D TMDs and could be relevant to future ...

Evaluating the Σ-effect Model of the Solar Hemispherical Helicity Bias via Direct Numerical Simulations

The Astrophysical Journal
The solar hemispherical helicity rule(s) (SHHR) is a term used to represent a bias observed in proxies for the magnetic helicity in active regions (ARs) at the solar surface.

Statistical Analysis of Magnetic Patches in Solar Active Regions using the Complex Network Method [PDF]

Iranian Journal of Astronomy and Astrophysics
Identifying solar active regions (ARs), which consist of one or more pairs of magnetic patches with opposite polarities, is essential due to their significant role in dynamic solar atmospheric phenomena such as solar flares and coronal mass ejections. In

Three-dimensional magnetohydrodynamics of the emerging magnetic flux in the solar atmosphere

The Astrophysical Journal, 1993
The nonlinear evolution of an emerging magnetic flux tube or sheet in the solar atmosphere is studied through 3D MHD simulations. In the initial state, a horizontal magnetic flux sheet or tube is assumed to be embedded at the bottom of MHD two isothermal gas layers, which approximate the solar photosphere/chromosphere and the corona.

Response of the Solar Atmosphere to Magnetic Flux Emergence from Hinode Observations [PDF]

Publications of the Astronomical Society of Japan, 2007
Abstract In the present work, we used optical and X-ray data from the Hinode satellite to study the response of the solar chromosphere and the corona to the emerging flux in the photosphere. In total, twelve emerging flux regions (EFRs) were selected to conduct this study.
