Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions
Advanced Functional Materials, EarlyView.Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

The relativistic solar particle event of 2005 January 20: origin of delayed particle acceleration
, 2014 The highest energies of solar energetic nucleons detected in space or through gamma-ray emission in the solar atmosphere are in the GeV range. Where and how the particles are accelerated is still controversial.

Advanced Functional Materials, EarlyView.Copper catalysts introduced with different non‐metallic elements regulating the coordination number of Cu are prepared by magnetron sputtering. Reducing the Cu coordination number enhances C─C coupling and boosts C2+ product selectivity, by lowering the energy barrier for the *CO → *CHO conversion step. The optimized Si‐doped Cu catalyst achieves a C2+

Advanced Functional Materials, EarlyView.A reproducible synthesis to control 3D/0D phase ratios via water‐tuned solvent–antisolvent methods is presented. Enhanced scintillation yield and ultrafast decay are achieved. Defect‐driven emission mechanisms are revealed through cathodoluminescence and radioluminescence, shedding light on the underexplored role of the 0D Cs4PbBr6 and mixed 0D/3D ...

High-harmonic Plasma Emission Induced by Electron Beams in Weakly Magnetized Plasmas
The Astrophysical JournalElectromagnetic radiation at higher harmonics of the plasma frequency ( ω ∼ n ω _pe , n > 2) has been occasionally observed in type II and type III solar radio bursts, yet the underlying mechanism remains undetermined.

Evidence for solar wind control of Saturn radio emission [PDF]
Using data collected by the Voyager 1 and 2 spacecraft in 1980 and 1981, strong evidence is presented for a direct correlation between variations in the solar wind at Saturn and the level of activity of Saturn's nonthermal radio emission.

Imaging Spectroscopy of Type U and J Solar Radio Bursts with LOFAR [PDF]
, 2017 Radio U-bursts and J-bursts are signatures of electron beams propagating along magnetic loops confined to the corona. The more commonly observed type III radio bursts are signatures of electron beams propagating along magnetic loops that extend into ...

Advanced Functional Materials, EarlyView.A scalable one‐step copolymerization strategy is developed to produce low‐cost microporous ion exchange membranes that boost both the efficiency and lifespan of flow batteries. When combined with organic electrolytes in aqueous systems, these membranes enable safe and cheap flow battery energy storage, supporting the widespread integration of renewable
