Advanced Science, EarlyView.We report a general strategy for meta‐selective C–H arylation using aryl iodides and a Pd(II)/Pd(IV) catalytic system guided by a removable directing group. DFT and experimental studies reveal that counter anion tuning (acetate to trifluoroacetate) significantly enhances selectivity.

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications
Angewandte Chemie, EarlyView.In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Graceful labeling of triangular extension of complete bipartite graph
Electronic Journal of Graph Theory and Applications, 2019 For positive integers m, n, Km, n represents the complete bipartite graph. We name the graph G = Km, n ⊙ K2 as triangular extension of complete bipartite graph Km, n, since there is a triangle hanging from every vertex of Km, n.

High‐Conductivity Electrolytes Screened Using Fragment‐ and Composition‐Aware Deep Learning
Advanced Science, EarlyView.We present a new deep learning framework that hierarchically links molecular and functional unit attributions to predict electrolyte conductivity. By integrating molecular composition, ratios, and physicochemical descriptors, it achieves accurate, interpretable predictions and large‐scale virtual screening, offering chemically meaningful insights for ...

Angewandte Chemie, EarlyView.We introduced a new synthetic strategy for the preparation of high metal loading crystalline single‐atom catalysts based on covalent organic frameworks with atomically distributed Pd ions and metal contents of up to 22.2 wt%. Theoretical simulations reveal that the crystalline framework dynamically confines Pd atoms between different binding sites ...

Advanced Science, EarlyView.This study presents an interfacial method to fabricate POC@polymer core–shell nanostructures combining cage porosity with polymer robustness. Through chiral self‐assembly and non‐solvent‐induced surface polymerisation, uniform ∼20 nm polymer‐coated particles are produced.

On the Number of α-Labeled Graphs
Discussiones Mathematicae Graph Theory, 2018 When a graceful labeling of a bipartite graph places the smaller labels in one of the stable sets of the graph, it becomes an α-labeling. This is the most restrictive type of difference-vertex labeling and it is located at the very core of this research ...

ON k-GRACEFUL LABELING OF SOME GRAPHS
Journal of applied mathematics & informatics, 2016 Summary: In this paper, it has been shown that the hairy cycle \(C_{n}\odot rK_{1},\) \(n\equiv 3\pmod 4\), the graph obtained by adding pendant edge to each pendant vertex of hairy cycle \(C_{n}\odot 1K_{1}\), \(n\equiv 0\pmod 4\), double graph of path \(P_{n}\) and double graph of comb \(P_{n}\odot 1K_{1}\) are \(k\)-graceful.

Topology‐Aware Machine Learning for High‐Throughput Screening of MOFs in C8 Aromatic Separation
Advanced Intelligent Discovery, EarlyView.We screened 15,335 Computation‐Ready, Experimental Metal–Organic Frameworks (CoRE‐MOFs) using a topology‐aware machine learning (ML) model that integrates structural, chemical, pore‐size, and topological descriptors. Top‐performing MOFs exhibit aromatic‐enriched cavities and open metal sites that enable π–π and C–H···π interactions, serving as ...
