Heme/NADH Mimics Co‐Decorated Allosteric Capsules for Regulating Oxygen Activation and Upregulating Intracellular Methionine Depletion

open access: yesAdvanced Science, EarlyView.
Through modifying the switchable µ‐oxo bridged FeIII‐porphyrins moiety and NADH mimics into a metal‐organic capsule, multiple responsive manners for O2 activation, chemical oxygenation and metabolic transformation have been demonstrated for upregulating intracellular methionine depletion and accumulation of methionine sulfoxide to achieve effective ...

Advances in Stabilizing Spinel Cobalt Oxide‐Based Catalysts for Acidic Oxygen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
This review systematically summarizes recent advances in enhancing the stability of spinel Co3O4‐based catalysts for the oxygen evolution reaction (OER) in acidic electrolytes. It discusses rational design strategies for obtaining durable Co3O4‐based OER catalysts, which can be applied in sustainable energy conversion and storage technologies ...

Spin‐State Engineering of Iron Phthalocyanine D‐Orbitals via Atomic Fe‐N4 Coupling for Enhanced Oxygen Reduction Reaction

open access: yesAdvanced Science, EarlyView.
We propose a strategy of coupling FePc to atomically dispersed Fe‐N4 sites, and design a composite catalyst (FePc‐Fe‐NCNT) that can synergistically tune the 3d electronic configuration of Fe. This strategy triggers a low‐spin to intermediate‐spin transition at Fe centers, balancing the adsorption and dissociation of oxygen‐containing intermediates. The

Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,

Bias‐Dependent Quantum Efficiency Reveals Recombination Pathways in Thin Film Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Bias‐dependent external quantum‐efficiency spectra provide three characteristic “fingerprints” that reveal whether charge‐carrier loss in high‐efficiency graded CdSeTe solar cells is dominated by the front interface, the bulk absorber, or the back contact.
