Modulating Electronic Structure of Atomic Iron Catalyst by Metallic Cobalt Cooperation for Boosting Oxygen Reduction/Evolution Reactions in Rechargeable and Flexible Zinc‐Air Battery

Carbon Energy, EarlyView.
Porous Co,Fe@NCNF‐900 catalyst has been innovatively synthesized as enhanced bifunctional catalysts by modulating the electronic structure of the atomic Fe catalyst through metallic Co cooperation. DFT analysis indicates that metallic Co as an electron donor can induce electron redistribution of the atomic Fe catalyst, thereby reducing the rate ...

Inhibitory Control Tells Only Part of the Story: Reward Sensitivity Moderates the Prospective Link Between the No‐Go P3 and Emerging Eating Pathology in Early Adolescents

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Early adolescence is characterized by the onset of mental health problems, including eating pathology (e.g., body image concerns, restrictive eating). Inhibitory control (IC) and reward sensitivity (RS) are two key traits that have been implicated in the development of eating problems.

Enhancing Anode‐Free Lithium Metal Batteries: A Lightweight MPTS‐MXene Current Collector for Superior Performance and Energy Density

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces an MPTS‐modified MXene current collector for anode‐free lithium metal batteries (AFLMBs). A key advantage of MPTS‐MXene is its ultralight weight, only 15% as heavy as standard copper per unit volume. Its special layered structure and Si‐O rich surface help lithium deposit smoothly and flat, while forming a protective layer that ...

Galvanic Esophageal Injury

Journal of Digestive Endoscopy, 2017
Foreign body ingestion is a common clinical problem met in paediatric practice. Though an expectant line of management is indicated in most instances, ingested button batteries warrant emergency endoscopy and retrieval.
