Knots are known for boosting the strength of materials, from the tiniest twists of DNA to (potentially) the very fabric of the universe. Now, Caltech engineers have developed a new material consisting ...

Polymer matrix composites (PMCs) are made by reinforcing a polymer-based matrix with glass, carbon, or aramid fibers. PMCs are classified into thermosetting and thermoplastic resins based on the type ...

An introductory course focused on the new and existing materials that are crucial for mitigating worldwide anthropogenic CO2 emissions and associated greenhouse gases. Emphasis will be placed on how ...

Carbon steel is an iron-carbon alloy. Although pure iron is not intrinsically strong, adding carbon imparts great strength to this material. Crude iron, which is used in steel production, has a high ...

Wood, long admired for its natural beauty and strength, has now inspired a carbon material tough enough to rival steel. Researchers at the University of Toronto have discovered that biochar derived ...
