Efficient Sunlight Degradation of Wide‐Spectrum Antibiotics Through Enhanced Charge Separation in SnTCPP NPs‐Nb2C Schottky Heterojunction: Ultrafast Carrier Dynamic Study

open access: yesAdvanced Materials Interfaces, EarlyView.
Due to enhanced charge transfer and carrier mobility on the surface, the SnTCPP NPs‐Nb2C Schottky heterojunctions demonstrate exceptional sunlight‐driven catalytic activity toward tetracycline antibiotics and ofloxacin degradation, achieving a removal efficiency of up to 99.9% within 60 min of irradiation, both in model wastewater and natural water ...

Spatial Relationship between CMEs and Prominence Eruptions during SC 24 and SC 25

open access: yesThe Astrophysical Journal
During their propagation, coronal mass ejections (CMEs) and prominences sometimes display a nonradial motion. During the years after the solar minimum, the CME central position angle tended to be offset closer to the equator compared to that of the ...

Inferring physical parameters of solar filaments from simultaneous longitudinal and transverse oscillations

open access: yesAstronomy & Astrophysics
Context. Different modes of oscillations are frequently observed in solar prominences, and prominence seismology helps estimate important physical parameters such as the magnetic field strength.

Initiation mechanisms of the erupting prominences

open access: yes, 2023
openSolar prominences are common features of the solar atmosphere and are often considered as precursor of large-scale dynamic events such as flares and coronal mass ejections (CMEs) which can disrupt the interplanetary medium and trigger geomagnetic ...

Sustainable Plant‐Based Water Repellent Coatings Using Hydrophobic Pine and Palm Pollen

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel formulation strategy for creating superhydrophobic coatings using plant‐derived waxes and chemically treated pine and palm pollen. By employing acid modification, the hydrophobicity of the pollen surface is enhanced, resulting in water contact angles exceeding 150°.

Cospatial Multiwavelength Observations of an Eruptive Prominence as the Bright Core of a Coronal Mass Ejection

open access: yesThe Astrophysical Journal Letters
Coronal mass ejections (CMEs), as seen in white-light (WL) coronagraphs, often exhibit a classic three-part structure consisting of a bright front, a dark cavity, and a bright core.

Halogen Surface Terminations in Ti3C2 MXenes for Interface Engineering in Perovskite Solar Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Controlled halogen surface terminations in Ti3C2${\rm Ti}_3{\rm C}_2$ MXenes enable the isolation of structure‐property relationships, revealing how –Cl and –Br terminations influence interlayer spacing, electronic behavior, and work function. When incorporated into IT‐4F‐based interfacial layers, these MXenes modulate interfacial processes and device ...
