Aspects of Ammonia as Green Fuel for Propulsion Systems of Inland Water Vessels

Energy Technology, Volume 13, Issue 2, February 2025.
Within the CAMPFIRE project, an ammonia‐powered propulsion concept is being developed for use in inland water vessels. The core of the system is an ammonia‐fueled high‐speed engine that drives a generator. A cracker splits some of the ammonia into hydrogen and nitrogen to ensure better ignition and efficient combustion.

The Raman Spectra of α$$ \alpha $$‐ and β$$ \beta $$‐Si3N4 and Si2N2O Determined Experimentally and by Density Functional Theory

Journal of Raman Spectroscopy, Volume 56, Issue 2, Page 155-164, February 2025.
Silicon nitride and silicon oxynitride are significant phases in ceramic materials with diverse applications. To accurately identify these phases in Raman images, high‐quality reference spectra are essential. These are presented here in comparison with spectra calculated using different DFT functionals.
