Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

On the SPANNING k-TREE problem

open access: yesDiscrete Applied Mathematics, 1993
A \(k\)-tree \(T\) is defined recursively as being either a clique of size \(k\) or having a vertex \(x\) whose neighbourhood is a clique of size \(k\) and such that \(T-x\) is a \(k\)-tree. (Note that \(k\)-trees are not trees, if \(k>1\).) The following SPANNING \(k\)-TREE problem is known to be NP-complete: given a graph \(G\), does \(G\) possess a ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...
