Ionic Metal Poly(heptazine Imides) and Single‐Atoms Interplay: Engineered Stability and Performance for Photocatalysis, Photoelectrocatalysis and Organic Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
Poly(heptazine) imides (PHIs), a crystalline carbon nitride subclass, intercalate metals to deliver high stability, tunable electronics, and efficient charge separation. These features enable solar‐driven applications such as hydrogen evolution, CO₂ reduction, and organic synthesis.

The Hermeneutic Problem of Potency and Activity in Aristotle [PDF]

open access: yes, 2017
Of Aristotle’s core terms, potency (dunamis) and actuality (energeia) are among the most important. But when we attempt to understand what they mean, we face the following problem: their primary meaning is movement, as a source (dunamis) or as movement ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Engineering Active CeO2/Fe3C Interfacial Sites to Generate High‐Charge‐Density Fe for Enhanced Oxygen Reduction Reaction Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.
