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

open access: yesEcoEnergy, 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)

Controlled Nanoarchitecture of Aligned Electrospinning Fiber Composite Electrolyte Based on Plant and Animal Biopolymers for Safe Na‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aligned Electrospun Composite Electrolyte. The resurgence of solid‐state Na+ battery, sustained through lithium deficiency and mounting costs, offers an auspicious alternative to solid‐state Li+ battery. This study introduces a nanoarchitectural approach that integrates electrospinning with a simple solution casting technique to develop a mechanically ...

Switchable Dual Emission of Luminescent Metal–Organic Framework@Nanoparticle Composites of EuBDC and ZrO‐Containing Hybrid Materials

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Luminescent metal–organic framework@nanoparticle composites show dual emission of both components EuBDC and zirconyl‐containing nanoparticles, being reversible, excitation energy‐dependent and solvatochromic switches. The chromaticity changes are fast, as no chemical transformation is involved and required as source of the dual emission.
