Modelling Thermal Halide Exchange of Perovskite Powders With and Without BMIMBF4 From an Interdiffusion Perspective

Advanced Functional Materials, EarlyView.
Halide diffusion limits the stability of hybrid halide perovskites for optoelectronic applications and thus needs to be quantified. This study presents an effective interdiffusion model to obtain time‐dependent diffusion coefficients for I− and Br− diffusion from in situ X‐ray diffraction data during the formation of a solid solution MAPbIxBr3‐x from ...

Dynamic Evolution of Magnetic Flux Ropes in Active Region 11429. II. Magnetic Characteristic of the Footpoints During the Preeruption and Eruption Phases

The Astrophysical Journal
Magnetic flux rope (MFRs) are the most probable core structure of coronal mass ejections (CMEs). Their footpoints on the photosphere are the only feature for which their magnetic properties can be accurately measured, and to some extent, determine the ...

Cryo‐EM of Rationally Designed Photosystem I Nanoassembly on Graphene Validates Orientation‐Driven Enhancement of Photocatalytic Performance

Advanced Functional Materials, EarlyView.
The first cryo‐EM visualization and quantification of oriented Photosystem I (PSI) on single‐layer graphene is reported. Domain‐specific covalent anchoring of PSI, with the reducing side of the biophotocatalyst toward graphene, promotes three‐fold higher anodic photocurrent generation compared to a randomly physisorbed counterpart. This approach allows

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Atmospheric Heating Events Associated with Fine-scale Flux Emergence in Ephemeral Regions

The Astrophysical Journal
Coronal heating has puzzled solar physicists for decades. The question of why the Sun’s upper atmosphere is significantly hotter than its lower atmosphere remains a key mystery.

Continuous‐Flow Photocatalytic Degradation of Glyphosate and Aminomethylphosphonic Acid Under Simulated Sunlight with TiO2‐Coated Poly(vinylidene fluoride) Membrane

Advanced Functional Materials, EarlyView.
Glyphosate (GLY) and its primary metabolite, aminomethylphosphonic acid (AMPA), are photodegraded using a poly(vinylidene fluoride) membrane with immobilized titanium dioxide (PVDF‐TiO2) in a continuous flow‐through operation under solar light. At optimized conditions, the PVDF‐TiO2 membrane achieved 95% GLY and 80% AMPA removal with •O2− as the ...
