Ultrahigh Strength with Suppressed Flow Instability at Liquid Helium Temperature via Coherent Nanoprecipitation in a Medium‐Entropy Alloy

open access: yesAdvanced Functional Materials, EarlyView.
It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

Burials of martial character in the British Iron Age [PDF]

open access: yes
The significance of the decision to bury an individual with martial objects during the British Iron Age cannot be overstated. It is a rare subset of funerary practice, conferred upon select individuals.

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Transvaal and Natal Iron Age settlement revealed by aerial photography and excavation [PDF]

open access: yes, 1968
African Studies Seminar series. Paper presented 1968In 1820 John Campbell visited a thriving Iron Age settlement built by the Hurutse tribe at that time under the regent Liqueling, and known as Kurrichane or Kaditshwene (spelling uncertain), believed ...

Magnetic Unclonable Functions Leveraging Remanence and Anhysteretic States

open access: yesAdvanced Functional Materials, EarlyView.
A micrometric array of magnetic pillars provides a stable and unclonable hardware for generating cryptographic keys. From a single device, the ability is demonstrated to produce a 470‐bit key while also offering a reconfigurable mode of operation.

Interfacial Control of Degradation Pathways in 2D Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
The stability of two‐dimensional (2D) heterostructures is governed not only by their intrinsic chemistry but also by interfacial effects. This study reveals how metallic versus insulating substrates impact the oxidation of air‐sensitive 2H‐MoTe2. Metallic layers act as charge reservoirs, mitigating degradation, while insulating ones accelerate it ...
