On the fourth atom-bond connectivity index of nanocones

Atom bond connectivity index is a topological index was defined as ABC(G) = Sigma(UV is an element of E(G)) root d(u)+d(v)-2/d(u)d(v) where d(v) denotes the degree of vertex v of G. Recently, M. Ghorbani et al.

All‐Amyloid Functional Coacervates

Advanced Materials, EarlyView.
This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

On the difference between atom-bond sum-connectivity index and Randić index of binary trees and chemical trees

Abstract Topological indices are numerical graph invariants generated from molecular graphs of chemicals to explain their structural properties. The atom-bond sum-connectivity (ABS) index and Randić (R) index are among the widespread graph invariants.

Extreme Bond Ionicity in Mg─Te Chalcogenides for Ultrathin Low Voltage Selector‐Only Memory beyond the Leakage Scaling Limit

Advanced Materials, EarlyView.
Mg─Te chalcogenides address the leakage scaling trade‐off in ultrathin selector‐only memory. Structural partitioning in multiphase Mg─Te, combined with highly ionic Mg─Te bonding and Hf interfacial engineering, supports reliable 5 nm thickness operation at low write voltage with suppressed leakage current, narrow threshold voltage distributions, 10 ns ...

The fifth version of atom bond connectivity index (ABC(5)) of an infinite class of dendrimers

, 2011
The atom-bond connectivity index-5(ABC(5)) is a new topological index defined as; ABC(5)(G) = Sigma(uv is an element of E(G)) root M-u + M-v - 2/MuMv where M-u denotes the product of the degrees of adjacent vertices of u.

Side‐Chain‐Induced Interlayer Slipping in Metalloporphyrin COFs Enables Microenvironment and Spin‐State Regulation for Photocatalytic CO2 Reduction

Advanced Materials, EarlyView.
Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.

On atom-bond connectivity index and its chemical applicability

, 2012
690-694A critical re-examination confirms that the atom-bond connectivity index (ABC) is well reproducing the heats of formation of alkanes (H°f). Moreover, the simple empirical formula H°f  = – (a+b·ABC), with a = 65.98, b = 20.37, reproduces ...
