Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels

Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

Advancing small‐angle X‐ray scattering for complex metallic systems: Ti2Cu precipitation in a martensitic near‐α Ti alloy

Journal of Applied Crystallography, Volume 58, Issue 6, Page 2006-2017, December 2025.
A novel small‐angle X‐ray scattering modelling approach is introduced for the analysis of precipitation behaviour in metallic systems exhibiting scattering signals with streaks originating from the embedding matrix. This approach enables in situ tracking of the microstructural evolution, such as the volume fraction and size of second phases, during ...

Steel Plates Subjected to Localised Blast Loading: Transient Measurements Using Ultra‐High‐Speed Camera Technology

Strain, Volume 61, Issue 6, December 2025.
ABSTRACT In this paper, we chart a path to a method that enables us to extract temporal and spatially varying pressure loading effects on the transient response of steel plates under near‐field blast loading, employing ultra‐high‐speed cameras and DIC to measure the transient deformation field. The study addresses the challenges of obtaining full‐field,

Artificial Intelligence and Nuclear Weapons Proliferation: The Technological Arms Race for (In)visibility

Risk Analysis, Volume 45, Issue 11, Page 3839-3859, November 2025.
ABSTRACT A robust nonproliferation regime has contained the spread of nuclear weapons to just nine states. Yet, emerging and disruptive technologies are reshaping the landscape of nuclear risks, presenting a critical juncture for decision makers. This article lays out the contours of an overlooked but intensifying technological arms race for nuclear ...

Robocasting of a Water‐Based Biopolymer/WO3 Nanopowder Paste as a Precursor to Tungsten Carbide Lattices

Advanced Engineering Materials, Volume 27, Issue 20, October 2025.
This study demonstrates a novel, additive manufacturing approach to produce complex, porous tungsten carbide structures using water‐based direct ink writing/robocasting. Leveraging a modified commercial printer and heat treatment, the process yields lightweight, electrically conductive 3D architectures capable of supporting a mechanical load.
