Comparison of 11-Atom Armchair Graphene Nanoribbons and Zig-Zag Carbon Nanotubes in Polymer Composites Under Various Bias Voltages: A Study of Electronic and Transmission Properties
Abstract: In this research, 11-atom zig-zag carbon nanotubes (ZCNTs) and 11-atom armchair graphene nanoribbons (AGNRs) were studied under applied bias voltages at 50, 150, and 300 millivolt levels. The focus was on understanding their behaviour concerning transmission qualities, current-voltage (I-V) characteristics, and energy-momentum (E-K) diagrams. The Non-Equilibrium Green's Function (NEGF) approach was employed to analyse various electronic properties for ZCNTs and AGNRs, including transmission, E-K relationships, and I-V characteristics. The results …

DFT/Data Guided Predictive Modelling of Absorption Maxima in the OLED Rubrene Derivatives
Abstract: This study investigates the optical properties of rubrene derivatives to develop an accurate predictive model for absorption maxima using computational chemistry and chemoinformatic techniques. We benchmarked various quantum chemical methods, identifying that the M06-2X/aug-cc-pVDZ method in dichloromethane (DCM) provided the strongest correlation with experimental data. Key molecular descriptors such as band gap, ionization potential, and electrophilicity index were calculated and analyzed using principal component analysis (PCA) to identify significant factors …

The Molecular Structure of Chemical Compounds by using Quantitative Calculations in Chemistry
Abstract: Computational chemistry has its roots in the early attempts of theoretical physicists, beginning in 1928, to solve the Schrödinger equation using mechanical calculating machines. These calculations verified that the solutions of the Schrödinger equation quantitatively reproduced experimentally observed properties of simple systems such as the helium atom and the hydrogen molecule. These approximate solutions of larger systems and exact solutions of simple model problems allowed chemists and physicists to provide …

Nanostructure-Induced Thermoelectric Enhancement in Bi₂Te₃ Nanorods Design, Analysis, and Performance Evaluation
Abstract: Thermoelectric materials capable of efficient energy conversion near room temperature are critical for waste heat recovery applications. In this work, solution-grown Bi₂Te₃ nanorods were synthesized via a trioctylphosphine-assisted thermal decomposition route, and the influence of surfactant-induced nanostructuring on their thermoelectric properties was systematically investigated. Structural analysis using X-ray diffraction and Rietveld refinement confirmed the formation of rhombohedral Bi₂Te₃ with the emergence of Bi₂Te₃–BiTe nanocomposites at higher surfactant concentrations.
