Wood Sawdust as a Low‐Cost Filler in Whole‐Tire Reclaimed Rubber: Mechanical Characterization and Factory‐Scale Cost Analysis

Journal of Applied Polymer Science, EarlyView.
Whole‐tire reclaimed rubber is upgraded with wood sawdust, a carpentry by‐product available at no cost, across loadings from 0 to 20 wt%. At 5 wt%, tensile strength, elongation, hardness, viscosity, and water absorption all stay within commercial specification, and real factory data show an annual production saving near $62,000 with no capital ...

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

Advanced 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 ...
