Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Advancing Energy Materials by In Situ Atomic Scale Methods
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

A unifying principle for global greenness patterns and trends
Vegetation cover regulates the exchanges of energy, water and carbon between land and atmosphere. Remotely-sensed fractional absorbed photosynthetically active radiation (fAPAR), a land-surface greenness measure, depends on carbon allocation to foliage ...

We report a Pt‐decorated Co‐doped BiFeO3 (Pt/BCFO) piezocatalyst achieving an H2 evolution rate of 1896.4 µmol g−1 h−1. Co‐doping induces lattice distortion, enhancing piezoelectric polarization, while Pt sites promote water dissociation. Embedded in a poly(vinylidene fluoride) matrix, Pt/BCFO enables efficient mechanical energy harvesting and catalyst

Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

This work presents an Os/FeP heterostructure catalyst with EMSI and successfully utilizes the BEF to further modulate electron transfer through Os‐P‐Fe channels, proving an effective approach of developing low‐cost electrocatalysts with remarkable HER activity in ampere‐level seawater electrolysis. ABSTRACT Developing cost‐effective and robust hydrogen

Redox evolutions of planetary mantle reservoirs constrained by titanium isotopes
The oxygen fugacity (hereafter referred as fO2) of terrestrial planets is key in defining the outcome of planetary-scale differentiation and the planets’ potential habitability.
