Deep Underground Science and Engineering, EarlyView.The graphical abstract illustrates the real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection. Under in‐situ hydrostatic pressure, the water invasion front advances progressively along the axial direction as the injection pressure increases stepwise, tracked in real time by nuclear magnetic ...

Unveiling Bubble Dynamics of Proton Exchange Membrane Water Electrolysis at Elevated Temperatures
EcoEnergy, EarlyView.This work directly visualizes bubble dynamics in a proton‐exchange membrane water electrolyzer operated at temperatures up to 120°C and pressures up to 100 bar. Elevated‐temperature operation beyond the atmospheric boiling point markedly reduces bubble coverage, leading to lower bubble‐related voltage losses and enhancing cell performance.

Hydride Materials for Advanced Electrochemical Energy Storage: Progress and Perspectives
EcoEnergy, EarlyView.Hydrides are emerging as functional materials for low‐carbon electrochemical energy storage. Complex hydrides provide polyanionic electrolyte frameworks for all‐solid‐state, Li–S, and multivalent batteries; hydride ion conductors enable H− transport for emerging hydride‐based cells; and metal hydrides offer established electrode chemistries for Ni–MH ...

IEEE Symposium Conference Record Nuclear Science 2004., 2005
Since GEM was introduced, it has been developed in many application areas. We have developed the neutron detector with GEM coated with the converting foil. The neutron efficiency of a foil was calculated with MCNP and TRIM. The neutron efficiency of multi GEM foils was also calculated.

The Detection of Slow Neutrons
2021This chapter introduces the physical concepts that underline the making and characterization of plastic-scintillator-based, slow neutron detectors. For this purpose, we shall introduce the physical concepts behind neutron emission, scattering, and absorption, as well as the interaction of reaction products inside the detection medium.

Since neutrons do not interact appreciably with electrons, they are always detected through effects caused by their collision with nuclei. Almost every type of nuclear interaction of neutrons results in a directly observable effect which has been used for the detection of neutrons. In the first part of the present article these various types of neutron-
