Wire Arc Directed Energy Deposition of Aluminum–B4C Composites

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
ABSTRACT The scalable fabrication of structural‐grade aluminum metal matrix composites (A‐MMCs) remains constrained by inherent limitations of conventional processing routes and laser‐based additive manufacturing (AM) methods. In this work, we demonstrate the development of a hybrid wire arc directed energy deposition (WA‐DED) platform for the near‐net‐

Aging and longevity in decades‐old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays

American Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, Volume 14, Issue 2, March-April 2026.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.
