Quantitative structure-properties relationship and molecular design of some anti-wear lubricant additives

open access: yesSouth African Journal of Chemical Engineering, 2020
In-silico QSPR and MD simulation methods were adopted to effectively design new lubricant anti-wear additive compounds as an alternative to zinc dialkyl dithiophosphate (ZDDP) which was reported to contribute to environmental pollution.

Assessing the effectiveness of Vertex‐ and Edge‐Degree‐Based Topological Indices for Modeling Physical Properties of Mononuclear Aromatic Hydrocarbons

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
There are many physical properties of mononuclear aromatic hydrocarbons (MAHs) are primarily governed by their environmental behavior, which affects their stability and activity with themselves or with other biological and environmental systems. This study revealed the predictive potential of topological indices (TIs) based on vertex and edge degrees ...

Exploring Graph Product Operations Through Eccentricity Connectivity Coindex: A Comprehensive QSPR Analysis of Octane Isomers

open access: yesJournal of Mathematics
In this article, the first eccentricity connectivity coindex is introduced as ECI¯G=∑uv∉EGε2u+ε2v, in which εu denotes the eccentricity of the vertex u in the simple connected graph G.

On Wiener Index for Generalised Subdivision Neighbourhood Corona of Graphs

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
Graph operations such as the corona product play a significant role in analysing and constructing complex networks. In this work, we examine the Wiener index within the framework of generalised subdivision graph operations. We establish precise bounds for the Wiener index of the generalised subdivision vertex neighbourhood corona for graphs with ...

Theoretical study on the structural effect of some organic compounds as corrosion nhibitors on mild steel in acid media

open access: yesBulletin of the Chemical Society of Ethiopia, 2009
A quantitative structure property relationship (QSPR) analysis of some organic compounds (imines or Schiff bases) is studied. The corrosion inhibition efficiencies of these imines have been studied by using AM1 (Austin model 1) Hamiltonian SCF-MO method ...

Eco‐Smart Ionic Liquids in the 21st Century: A Comprehensive Review on Molecular Innovation for Sustainable Environmental Solutions

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
Ionic liquids (ILs) have matured from laboratory curiosities to eco‐smart, molecularly tunable media underpinning sustainable chemical technologies. This review integrates a bibliometric mapping of the 2000–2025 literature with a critical synthesis of IL design principles, structure–property relationships, and application landscapes.

Some hypothesis on commonality in liquidity: New evidence from the Chinese stock market [PDF]

open access: yes
In this paper, we examine four specific hypotheses relating to commonality in liquidity on the Chinese stock markets. These hypotheses are: (a) that market-wide liquidity determines liquidity of individual stocks; (b) that liquidity varies with firm size;

QSPR analysis of air-to-blood distribution of volatile organic compounds

open access: yesEcotoxicology and Environmental Safety, 2008
Quantitative structure property relationship (QSPR) models for the prediction of human blood:air partition coefficient (log K(blood)) of volatile organic compounds (VOCs) has been developed based on the linear heuristic method (HM) and non-linear radial basis function neural networks (RBFNNs).
