Inversed Cation Size Effects on Methanol Formations From CO2 Electroreduction by Immobilized Cobalt Phthalocyanine

open access: yesAngewandte Chemie, EarlyView.
Multiscale simulations reveal an inversed cation size effect (Li+ > Na+ > K+ > Cs+) in immobilized cobalt phthalocyanine ‐catalyzed CO2 reduction to methanol. Smaller cations like Li+ effectively stabilize the rate‐limiting proton‐transfer transition state through intimate coordination, whereas their disruption of the local hydrogen‐bond network ...

Liquid‐Catalyst‐Activated Sparingly Solvating Electrolytes for Low‐Temperature Potassium‐Sulfur Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This study develops a novel sparingly solvating electrolyte for potassium–sulfur batteries, utilizing tetrahydrofuran (THF) to induce an anion‐dominated solvation structure that eases polysulfide shuttling and forms an inorganic‐rich solid–electrolyte interphases (SEI). Dimethyl diselenide (DMDSe) accelerates quasi‐solid‐state transformations, reducing

Bifurcation of *COOH Pathway Determines HCOOH Formation in CO2 Electroreduction on Bismuth

open access: yesAngewandte Chemie, EarlyView.
Driven by the mechanistic debate of Bi‐catalyzed CO2‐to‐HCOOH conversion, ambiguity remains regarding true reaction pathways. To resolve this, we combined constant‐potential AIMD simulations with spectroscopic evidence to analyze the competitive pathways.

Will the Semantic Web Change Education?

open access: yesJournal of Interactive Media in Education, 2004
: To say that the Web has affected many societies and cultures is to understate its impact along several dimensions. The Web is a technology which not only affects, but in some sense encompasses societies, cultures, and certainly institutions.

3D Interconnected Zn‐Ion Pathways Through Anionic Nanochannels Surrounding Bacterial Cellulose Nanofibers by Repetitive Interfacial Assembly for Aqueous Zn‐Ion Battery Separators

open access: yesAdvanced Energy Materials, EarlyView.
A repetitive interfacial assembly method is introduced to prepare a nanofibrillar separator with interconnected 3D anionic nanochannels for aqueous zinc‐ion batteries. The carboxylate‐rich nanochannels promote enhancements of Zn2+ ion transport and charge transfer at the electrode surface, and the 3D nanostructured hydrogels contribute to homogeneous ...
