Thermoelectric Response and Field‐Induced Figure of Merit in Fluorine–Doped Carbon Nanotube Using the Lorenz Number

open access: yesAdvanced Physics Research, EarlyView.
Thermoelectric conductivity decreases nonlinearly with increasing temperature for all investigated band‐gap values. Higher energy splitting yields lower conductivity, while smaller gaps maintain superior carrier transport. Peak response occurs at low temperature, followed by gradual saturation at elevated temperatures.

Exploration of Physical Properties of Sodium‐Based Perovskite Hydrides ANaH3 (A = Hf, Nb, Pd, Ru) for Hydrogen Storage Applications: First Principles Study

open access: yesAdvanced Physics Research, EarlyView.
First‐principles calculations reveal that ANaH3 (where A = Hf, Nb, Pd, Ru) perovskite hydrides combine structural stability, favorable electronic properties, and low hydrogen desorption temperatures (280–369 K). Strong metal–hydrogen interactions and reversible hydrogen storage characteristics identify these materials as promising candidates for ...
