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

What Causes the Asymmetry of Conjugate Hard X-Ray Footpoints in Solar Flares?
The Astrophysical Journal Supplement SeriesHard X-ray (HXR) emission in solar flares critically diagnoses nonthermal electron acceleration, transport, and precipitation. Observations commonly show asymmetric HXR photon fluxes between paired footpoints, whose physical origin remains debated, as ...

Advanced Materials Interfaces, EarlyView.Alkaline activation of halloysite clay nanotubes embedded in a chitosan matrix converts bionanocomposite films into porous geopolymeric materials with enhanced adsorption capacity toward hydrocarbons in both vapor and aqueous phases. The improved adsorption performance was demonstrated by the efficient capture of dodecane vapors and phenol from water ...

Statistical Overview of Long-lived Active Regions Observed across Multiple Carrington Rotations
The Astrophysical JournalThe study of solar active regions (ARs) is of central importance to a range of fundamental science, as well as the practical applications of space weather. AR emergence and life cycles are two areas of particular interest, yet the lack of consistent full-

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation
Advanced Materials Interfaces, EarlyView.Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

Advanced Optical Materials, EarlyView.Understanding exciton fine structure is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization‐sensitive photon‐echo spectroscopy in a magnetic field resolves exciton fine‐structure splittings hidden by inhomogeneous broadening, enabling direct determination of the bright‐dark ...

The Magnetic Fields at Different Levels in the Active Regions of the Solar Atmosphere [PDF]
Symposium - International Astronomical Union, 1971 The strengths of the longitudinal magnetic fields recorded at different depths of active regions with a double magnetograph of the Crimean Astrophysical Observatory are compared.The recordings of the magnetic fields were made in the lines Fe Iλ5250Å, Ca Iλ6103Å, Na I D1, BIIλ4554Å, Mg Iλ5184Å, Hα, Hγ, Hδ.It is shown, that there is a close correlation ...
