Laser‐Directed Energy Deposition of Ti2AlNb Alloy: As‐Deposited Ultrahigh Strength and Heat‐Treated Strength–Ductility Balance

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT An ultra‐high as‐deposited tensile strength of 1408 MPa—the highest reported value for laser‐directed energy deposition (L‐DED) fabricated Ti2AlNb alloy—is achieved in this study. The as‐deposited microstructure consists of coarse B2 grains with a high density of fine acicular O phase precipitates within the grains, along with a brittle α2 ...

Geometry‐Encoded Programmable Mechanics in Single‐Material Dual‐Phase Metamaterials

Small, Volume 22, Issue 50, 7 September 2026.
Inspired by the unique soft‐hard heterogeneous architecture of nacre, this study proposes a novel class of dual‐phase (DP) metamaterials. The DP metamaterials exhibit programmable nonlinear mechanical responses, tailored failure processes, and enhanced energy absorption by systematically varying the spatial coding patterns of soft‐hard unit cells ...

Transcriptional and Functional Insights Into the All‐Stage Resistance Gene GmRmd1‐Mediated Regulation of Resistance to Powdery Mildew in Soybean

Molecular Plant Pathology, Volume 27, Issue 9, September 2026.
GmRmd1 is a soybean all‐stage powdery mildew (PMD) resistance gene. Under normal conditions, GmWRKY27 and GmERF138 suppress the expression of GmRmd1. Upon Microsphaera diffusa infection, GmRmd1 interacts with GmRmd2, GmRmd3, GmRnl1 and GmPER1, forming functional protein complexes to regulate lignin biosynthesis and thereby modulate disease resistance ...
