Oxide Formation at the Sulfide Film‐Copper Interface in Anoxic Sulfide Solution and On‐Line Sulfide Detection Via Linear Polarization Resistance

open access: yesMaterials and Corrosion, EarlyView.
A flow through cell arrangement was used to examine the oxide formation at copper–copper sulfide interface in an anoxic, sulfide environment. Oxide formation on surface occurs because of exposure to aerated water during sample preparation. On‐line sulfide detection based on the linear polarization resistance of copper is also presented.

Alloy Solutions for Ammonia Cracking: A Review

open access: yesMaterials and Corrosion, EarlyView.
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

open access: yessteel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Control of welding residual stress for dissimilar laser welded materials [PDF]

open access: yes, 2008
The most common problem of welding dissimilar metals (DMWs) with respect to residual stresses is the differences in the coefficient of thermal expansion and heat conductivity of the two welded metals.

A Portable Multi‐Parameter Fluid Monitoring Unit for Real‐Time Measurements During Well Development and Geothermal Operations

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Monitoring of fluid parameters during well development, groundwater production, or geothermal operation is essential for the understanding of subsurface and well processes. We developed FluMoMax, a portable fluid monitoring unit, that can measure several physicochemical parameters in real‐time, to monitor fluid characteristics and to enable ...

DFT‐Based Insights Into Elastic, Thermophysical, Electronic, and Optical Properties of Topological Insulators XTe5 (X = Zr, Hf)

open access: yesAdvanced Physics Research, Volume 5, Issue 1, January 2026.
In this work, we present the first in‐depth investigation of elasto‐mechanical, thermophysical, and optical properties of these compounds. In particular, we analyzed the directional dependence of the elastic properties, explored the optical response for different photon polarization directions, and examined potential industrial applications of these ...
