Compositional design of strong and ductile (tensile) Ti-Zr-Nb-Ta medium entropy alloys (MEAs) using the atomic mismatch approach

, 2019
New non-equiatomic Ti(25+x)-Zr25-Nb25-Ta(25-x) (x = 0, 5, 10, 15, 20, in at%) medium entropy alloys (MEAs) have been designed using the atomic mismatch approach and fabricated through a conventional arc-melting process. These novel MEAs were derived from

From Source Waters to Rivers: Fe‐Rich Colloids Control Carbon and Metal Partitioning in Western Siberian Hydrological Continua

Hydrological Processes, Volume 40, Issue 10, October 2026.
Size fractionation across Western Siberian hydrological continua shows that colloidal partitioning reorganizes sharply from soil/fen waters to the first flowing waters. Major ions remain mostly low‐molecular‐weight, whereas Fe, P, REEs and hydrolyzing trace elements become associated with Fe/Al‐rich organo‐mineral colloids.

In Situ Formation of L12‐Al3Ti Precipitates Enabling High Strength and Toughness in Oscillating Laser‐Welded Aluminum Alloy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT A synergistic strategy combining a Ti interlayer and circular beam oscillation was proposed to improve the laser weldability of 6082‐T6 aluminum alloy. The Ti interlayer suppressed porosity, eliminated columnar grains, and significantly reduced grain size by 67.7% at the weld center. Mechanistically, fine L12‐Al3Ti precipitates clearly showing

Facet‐Regulated MOF Nanosheets Enable Ion‐Selective Separators for Stable Lithium Metal Batteries

SmartMat, Volume 7, Issue 5, October 2026.
Facet‐guided synthesis of ultrathin Zn(bim)(OAc) MOF nanosheets enables an ion‐selective separator coating for lithium metal batteries. Exposed metal sites and hydroxyl‐rich surfaces immobilize mobile anions, accelerate Li+ migration, and homogenize interfacial ion flux.
