Toward Understanding the Stability of Single‐Atom Catalysts in Oxygen Evolution Reactions

Advanced Energy Materials, EarlyView.
Enhancing the stability of single‐atom catalysts for the oxygen evolution reaction hinges on understanding support interactions, local geometry, and structural dynamics. Transitioning to OH‐modified surfaces offers a promising route to cap surface metals and prevent leaching, paving the way for the next generation of stable OER SACs.

Impeding Thermal Atomization Enables Synthesizing Fe2N Cluster Liganded Single Fe‐Atom Catalyst for Highly Efficient Oxygen Reduction Reaction

Angewandte Chemie, EarlyView.
Fe2N cluster liganded single‐atom Fe‐N‐C catalyst was made via impending the conventional thermal atomization process. The in situ generated Fe2N clusters can optimate the electronic structures of Fe‐N4 sites, thereby rendering Fe2Nnc/Fe1‐N‐C catalyst a record‐high oxygen reduction activity of 0.957 V versus RHE in alkali condition.

Self‐Standing Fluorine‐Free Anode Microporous Layers Enabling Improved Hot and Dry Operation of Fully Hydrocarbon Proton‐Exchange Membrane Fuel Cells

Advanced Energy and Sustainability Research, EarlyView.
Fluorine‐free self‐standing anode microporous layers are fabricated and optimized for hydrocarbon catalyst‐coated membranes. The effects of carbon black, graphite, and acrylic binder in the microporous layer composition, on wetting behavior, permeability, electrical resistance, and electrochemical performance are investigated.

Interplay Between Stereochemically Active Lone Pair Repulsions, Sigma Hole Interactions, and Delocalized Redox Processes in Topochemical Fluoride‐Ion Insertion

Angewandte Chemie, EarlyView.
Fluoride‐ion insertion and diffusion within Sn2TiO4 is mediated by the complex interplay between the formation of Sn─F dative interactions and redox processes delocalized across Ti─O─Sn hybrid states counterbalanced by repulsions between fluoride‐ions and stereochemically expressed Sn 5s2 electron lone pairs.

Multipartite graph decomposition: cycles and closed trails

Le Matematiche, 2004
This paper surveys results on cycle decompositions of complete multipartite graphs (where the parts are not all of size 1, so the graph is not K_n ), in the case that the cycle lengths are “small”.

Volatility analysis and forecasting of vegetable prices using an ARMA‐GARCH model: An application of the CF filter and seasonal adjustment method to Korean green onions

Agribusiness, EarlyView.
Abstract The vegetable market experiences significant price fluctuations due to the complex interplay of trend, cyclical, seasonal, and irregular factors. This study takes Korean green onions as an example and employs the Christiano–Fitzgerald filter and the CensusX‐13 seasonal adjustment methods to decompose its price into four components: trend ...

Multifunctional Framework Nucleic Acid Vehicle for Antibiotic Sensitization and Treatment of Methicillin‐Resistant Staphylococcus aureus

Aggregate, EarlyView.
A self‐assembling, aggregation‐enhanced tetrahedral DNA nanostructure (tFNA), termed TACs, enables localized accumulation and sustained release of ceftriaxone while co‐delivering antisense oligonucleotides that silence mecA, reduce PBP2a expression, and restore β‐lactam susceptibility in MRSA.

Enhancing Clinical Detection Accuracy of Large Structured Viral RNA via DNAzyme Cleavage and Antisense‐Assisted Rolling Circle Amplification

Angewandte Chemie, EarlyView.
We show that antisense oligonucleotides can be used to restructure secondary structural elements around the circular DNA template binding sites of the genomic RNA for subsequent rolling circle amplification. This strategy was employed to identify otherwise COVID “false negative” saliva samples by accurately detecting the presence of SARS‐CoV‐2 genomic ...
