Built‐In Electric Field in 2D/2D LDH/Antimonene Heterostructure to Induce Stable β‐NiOOH at Ultralow Potential for Cost‐Effective Water Electrolysis

Advanced Functional Materials, EarlyView.
In this paper, a built‐in electric field (BEF) strategy is proposed to fabricate NiFe‐LDH/antimonene heterostructure as bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The formed BEF generates a local potential that reduces the potential for the formation of β‐NiOOH, thereby enabling ultra‐low ...

Low‐Temperature Exsolution of Cobalt From Perovskite Nanoparticles via Bead Milling for Enhanced Electrocatalytic Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
High‐temperature requirements and complex synthesis limit the practical use of perovskite‐based metal exsolution catalysts. This study addresses these limitations by employing bead milling, enabling efficient metal exsolution at a significantly lower temperature (300 °C) from La0.6Sr0.4CoO3‐δ nanoparticles. Consequently, the catalytic mass activity for

Properties of planets in binary systems. The role of binary separation [PDF]

, 2006
The statistical properties of planets in binaries were investigated. Any difference to planets orbiting single stars can shed light on the formation and evolution of planetary systems. As planets were found around components of binaries with very different separation and mass ratio, it is particularly important to study the characteristics of planets ...

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

Advanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

Implications of the TTV-Detection of Close-In Terrestrial Planets Around M Stars for Their Origin and Dynamical Evolution

, 2010
It has been shown that an Earth-size planet or a super-Earth, in resonance with a transiting Jupiter-like body in a short-period orbit around an M star, can create detectable TTV signals (Kirste \& Haghighipour, 2011). Given the low masses of M stars and

Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction

Advanced Functional Materials, EarlyView.
Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...
