Inverse Grading Emerges From Particle‐Scale Migration Under Seasonal Freeze‐Thaw Forcing: Evidence From Multi‐Year Monitoring and Physical Modeling

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Inverse grading, where coarse particles overlay finer materials, is common on talus slopes, yet its progressive formation under realistic conditions is rarely quantified. We integrate multi‐year field observations with controlled freeze‐thaw experiments to elucidate the processes driving particle migration that result in inverse grading and ...

On the Impact Energy Absorption of an Advanced High‐Strength Bilayer Steel Composite Consisting of Carbide‐Free Bainitic Steel and High‐Mn Twinning‐Induced Plasticity Steel

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

Characterization of the Carbonyl Metalates [Mn2(CO)8]2− and [W2(CO)8]4− Featuring M=M Double Bonds

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 5, 18 March 2026.
The novel homoleptic carbonyl metalate anions [Mn2(CO)8]2− and [W2(CO)8]4− featuring M=M double bonds are structurally characterized and investigated using quantum chemical calculations and QTAIM methods. The crystal structures of [Rb[2.2.2]crypt]2[Mn2(CO)8] ⋅ 4NH3 and [K[18]crown‐6]2K2[W2(CO)8] ⋅ 14NH3 are reported, containing the first homoleptic ...

Na4Ba9MnN3: A New Subnitridometalate with Trigonal Planar Anions [MnIIIN3]6−

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
The new subvalent nitridomanganate(III) Na4Ba9MnN3 contains structural elements known from ionic subnitridometalates as well as from intermetallic phases. In similarity to Ba3MnN3, isolated trigonal planar nitridomanganate(III) anions (MnN3)6−, coordinated by barium atoms represent the ionic region, while mixed barium‐sodium icosahedra known from ...
