Ultrathin Al2O3‐Coated Biomass Carbon for Sodium‐Ion Batteries via a Synergistic Storage Mechanism

Carbon Energy, EarlyView.
An ultrathin Al2O3 coating on biomass‐derived carbon effectively passivates surface defects, stabilizes the SEI, and enables a synergistic “adsorption–intercalation–filling” sodium storage mechanism. This strategy delivers outstanding cycling stability, fast Na+ kinetics, and broad temperature adaptability, demonstrating strong potential for practical ...

Regulating Interfacial Hydrogen‐Bonding Connectivity by Oxygen Vacancies‐Driven [Fe(CN)6]3− Coordination for Boosting Hydrogen Peroxide Electrosynthesis

Carbon Energy, EarlyView.
ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

The Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Manipulating the d‐Band Center of Ir by Metal‐Support Interaction to Optimize the Adsorption for Self‐Powered Hydrazine Oxidation‐Assisted Hydrogen Generation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The d‐band center of Ir in Ir@BNC is synergistically regulated by B and N elements with large electronegativity differences and thus Ir@BNC exhibits eminent performances for both HER and HzOR, requiring −25 and 18 mV to reach 10 mA cm−2 in alkaline conditions. The OHzS device can be powered by DHHPFC and realize hydrogen production at a stable rate (53.
