Comparative study of Sombor index and its various versions using regression models for top priority polycyclic aromatic hydrocarbons.

The aromatic compounds having structural configurations with two or more fused benzene rings are the polycyclic aromatic hydrocarbons (PAHs). Topological indices are valuable tools for studying the structure property relationships of PAHs and also helps in predicting various properties and activities. They find applications widely in computational chemistry, drug design and QSPR studies.

A QSPR analysis and curvilinear regression models for various degree-based topological indices: Quinolone antibiotics.

Topological indices play an essential role in defining a chemical compound numerically and are widely used in QSPR/QSAR analysis. Using this analysis, physicochemical properties of the compounds and the topological indices are studied. Quinolones are synthetic antibiotics employed for treating the diseases caused by bacteria.

Evaluation of the Linear Relationship of the Inferior Alveolar Nerve Canal to the Lateral Cortex and the Alveolar Crest in the Posterior Mandible: A Computed Tomographic Study.

Background And Objective: A cross-sectional study was conducted to evaluate a clinically relevant position of the inferior alveolar nerve and canal with respect to the lateral cortex, alveolar crest, and first and second molar root apices in adult dentate patients.

Methods: The study was conducted in the patients who reported various oral and maxillofacial surgical procedures at the Department of Oral and Maxillofacial Surgery for whom preoperative computed tomography (CT) scan was taken for the required surgical procedures. CTs were selected based on the selection criteria, and a total of 50 CTs were evaluated.

Chemical applicability and computation of K-Banhatti indices for benzenoid hydrocarbons and triazine-based covalent organic frameworks.

The novel applications in chemistry include the mathematical models of molecular structure of the compounds which has numerous findings in this area that refers to mathematical chemistry. Topological descriptors play a major role in QSAR/QSPR studies that analyses the biological and physicochemical properties of the compounds. In the recent times, a new type of topological descriptors are proposed, called K-Banhatti indices.

Dual-Emissive Carbon Dots: Exploring Their Fluorescence Properties for Sensitive Turn-Off-On Recognition of Ferric and Pyrophosphate Ions and Its Application in Fluorometric Detection of the Loop-Mediated Isothermal Amplification Reaction.

In this study, dual-emissive carbon dots (CDs) were prepared using -phenylenediamine (PDA) and phytic acid (PA) precursors via a one-pot-hydrothermal method. The photophysical, morphological, and structural characterization of CDs was carried out using absorption, fluorescence, Fourier transform infrared (FT-IR) spectroscopy, nuclear magnetic resonance (NMR), and high-resolution transmission electron microscopy (HR-TEM) analysis. The as-prepared CDs displayed dual-fluorescence peaks at 525 and 620 nm upon excitation at 450 nm.
