Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

steel research international, EarlyView.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Inferring cumulative crack widths in reinforced concrete structures using Coda Wave Interferometry of ultrasound

Structural Concrete, EarlyView.
Abstract Whether concrete structures are cracked, how wide these cracks are, and whether they must be regarded as damaging, is a central issue in structural health monitoring. Ultrasonic measurements evaluated with the sensitive Coda Wave Interferometry (CWI) have the potential to detect cracks early—long before they become visible. This paper presents

Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

The Chemical Record, EarlyView.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...

Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, EarlyView.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

High Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...
