A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Buried Interface Engineering via a Bifunctional Guanidino‐Carboxyl Molecular Bridge for Enhanced Performance and Stability in Perovskite Solar Cells

EcoEnergy, EarlyView.
A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...

Thermal niche breadth shapes regional elevational range sizes of tropical‐like mountain stream insects: evidence for Janzen's tropical mountain passes hypothesis

Ecography, EarlyView.
The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by
