X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Proceedings of the International Astronomical Union, 2005 The discovery of binaries in each of the major populations of minor bodies in the solar system is propelling a rapid growth of heretofore unattainable physical information. The availability of mass and density constraints for minor bodies opens the door to studies of internal structure, comparisons with meteorite samples, and correlations between bulk-

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots
Advanced Functional Materials, EarlyView.CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Correlated Metal LaNiO3 as a p‐Type Transparent Conductor
Advanced Functional Materials, EarlyView.p‐type transparent conducting oxides are needed to enable superstrate solar cell geometries with n‐type absorbers. The p‐type correlated metal LaNiO3 combines high optical transmission with low electrical resistivity and is compatible with a range of scalable deposition processes.

Diversity of the morphology of type II spicules in MURaM-ChE simulations
Astronomy & AstrophysicsContext. Spicules are ubiquitous, small-scale features in the solar atmosphere, exhibiting a jet-like appearance most clearly identified by their apparent motion in off-limb observations. While they are often interpreted as narrow, thread-like structures,
