ChemSusChem, Volume 18, Issue 9, May 5, 2025.Extensive physico‐chemical characterizations of electrolytes obtained by dissolution of LiTFSI in sulphone‐based solvents and their mixtures are presented. Their conductive properties are discussed in connection with the structural description provided by Raman spectral evidence. Abstract This work illustrates a physico‐chemical study of the structural,

Digest of Middle East Studies, Volume 34, Issue 3, Summer 2025.ABSTRACT The Arab Spring resulted in an expansion of social and individual freedoms in Tunisian society, but it also brought political instability, negatively impacting what had long been the country's primary source of employment—tourism. This economic crisis forced many to improvise their own sources of income, and it was in this context that a new ...

Global Fossil Methane Emissions Constrained by Multi‐Isotopic Atmospheric Methane Histories
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.Abstract The global CH4 budget of sources and sinks is highly uncertain, particularly the emissions from specific sources such as fossil fuels (FF) or agriculture. Here, we estimate plausible global CH4 source and sink scenarios using historical observations and simulations of atmospheric CH4 mole fraction and its stable isotopic (δ13C‐CH4, δD‐CH4) and

Distributed multi‐layer control of hybrid AC/DC grids: Design and experimental validation
IET Renewable Power Generation, Volume 18, Issue S1, Page 4414-4425, 18 December 2024.The decentralisation of the electrical system requires the development of new control algorithms to compensate for the intermittent and non‐deterministic nature of renewable energy sources and emerging electrical loads. This paper proposes a distributed multilayer control scheme based on model predictive control, applied across various portions of the ...
