Enhanced Contribution of Biexciton‐Mediated Decay Kinetics in Perovskite Nanocrystals Via Sequential Ultrafast Excitation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sequential ultrafast excitation is shown to increase the relative kinetic weighting of biexciton‐mediated decay in CsPbBr3 nanocrystals without increasing the total excitation fluence. By temporally structuring excitation within the exciton lifetime, the early‐time fast decay contribution becomes more pronounced while the fitted fast decay constants ...

Lattice‐Strained Cu2O‐Ni/NiO Heterostructure Enables Selective Electrocatalytic C–C Coupling of Alcohols to Cinnamaldehyde in Aqueous Medium

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved the selective oxidation C–C coupling of PhCH2OH with EtOH to form cinnamaldehyde (CAL) on a designed Cu2O‐Ni/NiO heterojunction catalyst. By employing a salt precipitation strategy to balance the pH and cation concentration, an 86% conversion rate of PhCH2OH and a 67% high selectivity for CAL were realized.

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

Quantifying Efficiency Roll‐Off Factors in Quantum‐Dot Light‐Emitting Diodes

open access: yesAdvanced Science
The application of quantum‐dot light‐emitting diodes (QLEDs) is hindered by efficiency roll‐off at high current densities. Factors contributing to this roll‐off include Auger recombination, electric field‐induced quenching, Joule heating, and electron ...
