Neutron/Gamma Mixed Spectrum Radiolysis-based Aqueous Dosimetry [PDF]
, 2007 This work develops a method to use an aqueous dosimeter in a mixed radiation field to determine separate measurements of neutron and gamma dose. Based on radiolysis of both Fricke and Methyl Viologen (MV) solutions, activation analysis and reactor ...

High resolution position sensitive neutron detection
, 2022 The fast neutron flux from a 14 MeV neutron generator has been measured time-, position- and energy-dependent. In this paper we report especially on a method for determination of the spatial flux distribution.

Concepts, Instrumentation and Techniques of Neutron Activation Analysis
, 2013 Following the discovery of neutron by J. Chadwick in 1932 (Nobel prize, 1935) and the re‐ sults of F. Joliot and I. Curie in 1934, neutron activation analysis was first developed by G. Hevesy and H. Levi in 1936.

A Neutron Activation Analysis Technique for Determination of the Precious Metals and its Application to a Study of their Geochemistry [PDF]
, 1968 A neutron activation analysis procedure for the simultaneous determination of Ru, Pd, Os, Ir, Pt and Au has been developed. It consists principally of distillation, anion exchange, solvent extraction and precipitation steps and was used to determine all

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes
Advanced Materials, EarlyView.This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells
Advanced Materials Interfaces, EarlyView.Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.
