A multiscale study on the microstructure and hardening models of the irradiation defects on reactor pressure vessel steels: Modelling and experiment

Journal of Materials Research and Technology
Irradiation defects are known to impede the dislocation motion in irradiated reactor pressure vessel (RPV) steels. However, consistent experimental studies of the respective irradiation defects and relevant theoretical studies of the interaction ...

Hydrogen‐Based Reduction of Hematitic Iron Ore in a Fluidized Bed Kinetic Reactor at Elevated Pressures

steel research international, EarlyView.
This study investigates the reduction behavior of two international iron ores, including a synthetic hematite produced by oxidation of magnetite, in a novel fluidized‐bed kinetic reactor at elevated pressures. The reduction takes place at various temperatures (650°C, 700°C, and 750°C), and various hydrogen partial pressures (30, 55, and 80 vol% H2 ...

Improving the safety and reliability of reactor pressure vessel steels

, 2019
The mechanical properties of reactor pressure vessel (RPV) steels are known to degrade during operation. Hardening embrittlement, due to solute cluster/precipitate formation, and non-hardening embrittlement, as a result of solute segregation to internal interfaces, are a major concern.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Sustainability Assessment of Alternative Methods for Destruction of Per‐ and Polyfluoroalkyl Substances (PFAS) in Water

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely recognized for their resistance to degradation and potential adverse health effects. The treatment of PFAS‐contaminated aqueous media (e.g., drinking water, wastewater, and leachate) has been extensively studied in the published literature; however, the

Investigation of the Phase‐Separation Point During CO2 Absorption in the DETA–Sulfolane–Water System

Carbon and Hydrogen, Volume 28, Issue 3, Page 406-417, September 2026.
Optical scattering diagnostics combined with generalized solubility product modeling enables quantitative prediction of phase separation in DETA–sulfolane–water biphasic CO2 absorbents. ABSTRACT The phase‐separation behavior of liquid–liquid biphasic amine absorbents is typically identified using bubbling reactors, where visual observation is employed ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4787-4808, September 2026.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Modelling of solutes in ferritic reactor pressure vessel steels

, 2020
The lifetime of a steel reactor pressure vessel (RPV) is dictated by its toughness which is gradually reduced during operation due to the elevated temperature and high energy neutron flux leading to the formation of nanoscale defects in the form of matrix damage and solute-vacancy clusters composed primarily of Cu, Mn, Ni and Si. However, the mechanics
