In the energy conversion context, design and synthesis of high-performance metal-free carbon nanomaterials with topological defects for oxygen reduction reaction (ORR) are essential. Herein, we first report a template-assisted strategy to fabricate defect electrocatalysts rich vacancy coupling pentagons (VP) as active sites in two-dimensional (2D) nanosheets (VP/CNs). Experimental characterizations verify presence abundant VP VP/CNs electrocatalyst, ORR activity is linearly related amounts...
In situ and accurate measurement of the structure dynamics interfacial water in hydrogen evolution reaction (HER) is a well-known challenge because coupling among varied structures its dual role as reactants solvents. Further, interference bulk intricate interactions always hinders probing water. Surface-enhanced infrared absorption spectroscopy extremely sensitive for water; herein, we develop nanoconfinement strategy by introducing nonaqueous ionic liquids to decouple tailor electric...
Abstract Heterodimers of metal nanocrystals (NCs) with tailored elemental distribution have emerged as promising candidates in the field electrocatalysis, owing to their unique structures featuring heterogeneous interfaces distinct components. Despite this, rational synthesis heterodimer NCs similar composition remains a formidable challenge, and impact on electrocatalysis has remained largely elusive. In this study, Pd@Bi‐PdBi are synthesized through an underpotential deposition...

Abstract Molecular dynamics simulations were used to study the thermal conductivity of liquid argon ultra thin films confined between two plates spaced several nanometres apart. The research focused on dependence layer thickness and interaction solid. results show that depends distance existence solid-like layering at liquid–solid interface average migration frequency all molecules. Stronger interactions solid resulted in a larger number atoms along surface hence smaller resistance However,...
Chirality, also known as handedness, is one of the most widespread and intriguing properties in nature, touching upon various fields including physics, chemistry, biology, medicine beyond. Chiral interface place where chirality related process occurs. The development synthetic chiral not only deepens understanding mechanism, but provides basis for application phenomenon. In this review, we provide a summary types interfaces, their construction methods, recent recognition, separation,...
The preparation of high-quality highly oriented metal–organic framework (MOF) thin films is desirable for developing advanced functional devices. However, the pathways controlling growth MOFs are largely unknown, and determining their microcosmic evolution at complex solid–liquid interface remains a challenge.

In this study, two models were simulate thermal conduction across micro contact points the resistance using non-equilibrium consideration of near field radiation. When ratio length region is less than 0.125, influence radiation should be considered; but when larger 0.2, it can neglected. computational domain sizes are...
