Advantages of Pulsed Laser Ion Source (LIS) at an Intensity of About 1010 W/cm2 for Heavy‐Ion Injection Into High‐Energy Accelerators

Contributions to Plasma Physics, EarlyView.
ABSTRACT At the Laser Plasma Physics laboratories of the University of Messina, an experimental platform for generating and accelerating low‐energy ions (keV) using pulsed lasers and for their potential applications has been put into operation. A Q‐switched Nd:YAG laser produces the beam for the system, operating at 1064 nm.

Perceived importance and didactic difficulty of chemistry education: Insights from Czech teachers

The Curriculum Journal, EarlyView.
Abstract This empirical study examines how chemistry teachers in lower and upper secondary schools in the Czech Republic evaluate the content of the chemistry curriculum, focussing on its perceived importance and didactic difficulty. Based on a quantitative survey (N = 146), the study provides insight into the pedagogical content knowledge of ...

Real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection: Combined low‐field nuclear magnetic resonance and multifractal approach

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 ...
