Handed Magnon Propagation in Easy‐Axis Antiferromagnetic α‐Fe2O3

Advanced Materials, EarlyView.
Coherent excitation and detection of handed magnons are achieved in the easy‐axis antiferromagnet α‐Fe2O3. An external magnetic field lifts the degeneracy between left‐ and right‐handed magnons without affecting their propagation velocity. The Dzyaloshinskii–Moriya interaction and anisotropy modulate their amplitude and damping, enabling intrinsic ...

Performance Constraints of All‐Perovskite Tandem Solar Cells in Low‐Intensity, Low‐Temperature Environments

Advanced Materials, EarlyView.
All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

A test for the redshift dependence of $$\sigma _8$$ σ 8 using $$f\sigma _8$$ f σ 8 measurements

European Physical Journal C: Particles and Fields
We search for a redshift dependence of $$\sigma _8^0$$ σ 8 0 using 23 growth rate measurements from redshift space distortions and peculiar velocity measurements as a consistency check of $$\Lambda $$ Λ CDM.

Study on the Gamma-Ray Radiation Properties of High-Redshift Blazars at z > 2.5

Universe
The high-redshift blazars are important cosmological probes for exploring the early universe and unraveling the fundamental emission processes and the structure of the active galactic nuclei.

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

Advanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

A Quasi‐Solid Ionic Liquid‐Polymer Hybrid Electrolyte for Shuttle‐Free and Dendrite‐Free Aqueous Zinc─Bromine Batteries

Advanced Materials, EarlyView.
A quasi‐solid ionic liquid‐polymer hybrid electrolyte is proposed to achieve shuttle‐free and dendrite‐free aqueous Zn─Br batteries. Synergetic effects between Zn2+ selective conduction of polyanionic network and polybromide complexing additive suppress the shuttle effect and improve Zn reversibility.
