Monte Carlo evaluation of neutron irradiation damage to the VVER-1000 RPV
Nuclear Energy and Technology, 2017 Neutron irradiation damage is of the most critical damage mechanisms in nuclear power plant's pressure vessel. Neutrons transfer their kinetic energy to target atoms of RPV that start to jump creating vacancies and interstitials known as Frenkel Pair (FP)

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 ...

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.

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.Disk openings regulate devolatilization during horizontal melt polycondensation. In polyethylene naphthalate, a four‐opening disk maximizes the apparent EG volumetric mass‐transfer coefficient and aligns EG removal with its generation, shifting equilibrium forward.

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
