Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

open access: yesAdvanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

MoO2‐Mediated Ni─Fe Bond Contraction and Electronic Modulation in Ni3Fe Alloy for Efficient Water Electrolysis at High‐Current‐Densities

open access: yesAdvanced Materials, EarlyView.
MoO2 effectively modulates the electronic structure of Ni3Fe and optimizes the Ni─Fe bonding configuration, thereby enabling dual regulation of the Volmer‐Heyrovsky steps and the evolution pathways of reaction intermediates during the water electrolysis process, which collectively accelerates both the hydrogen evolution reaction and oxygen evolution ...

Covalent Organic Framework and Carbon Nitride Composite for Scalable Solar Reforming

open access: yesAdvanced Materials, EarlyView.
A modular composite, containing a covalent organic framework, indium tin oxide, carbon nitride and nickel based molecular catalyst, enables solar reforming under neutral aqueous conditions, converting polyols and sugars into formate while generating H2.

Heterogenized Copper(II) Phenanthroline Catalysts for Electroreduction of CO2 to C2 Compounds: Substitution on the Ligand Causes Structural Changes to the Molecular Framework and Stability Enhancement

open access: yesAdvanced Materials, EarlyView.
Based on a previously reported binuclear Cu(II) phenanthroline catalyst, a structurally modified version with enhanced stability for electrochemical reduction of CO2 is developed. The second‐generation system allows for stable operation in an MEA electrolyzer with a Faradaic efficiency of >70% for C2 products at elevated current densities.
