Comparative Evaluation of Structure–Processing–Property Relationships in Flax, Hemp, and Cattail Discontinuous fiber Thermoset Composites

Polymer Composites, Volume 47, Issue 15, Page 13910-13926, 10 August 2026.
Needle punching reorients fibers from in‐plane direction toward z‐direction of the web, resulting in mechanical interlocking of fibers and reduction in the nonwoven mat thickness. ABSTRACT Replacement of glass fiber mats, utilized in large and complex composite parts in the transportation industry, with natural fiber mats requires knowledge of natural ...

The Impact of Al and P Vacancy‐Complexes in Monolayer 2D SiC for Application in Electronic Devices: A Density Functional Theory Study

Advanced Theory and Simulations, Volume 9, Issue 8, August 2026.
Hybrid density functional theory reveals that Al‐ and P‐related vacancy complexes significantly modify the structural, electronic, and magnetic properties of a 2D SiC monolayer. The studied defects exhibit thermodynamic stability, induce notable magnetic moments and spin polarization, and demonstrate tunable charge‐transfer behavior, highlighting their
