Dry Reforming of Biogas Over Li–Ni–Al Catalysts: Influence of Li Incorporation Method
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Hydrogen is a promising source of energy, given the current context of depletion of fossil fuels and increased emissions of greenhouse gases. The technological route for obtaining this fuel from the dry reforming of biogas has received considerable attention from researchers, as it converts the polluting gases CH4 and CO2 into synthesis gas ...

Journal of Applied Toxicology, EarlyView.ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Tourism, Democracy and Economic Growth in Africa
Journal of International Development, EarlyView.ABSTRACT While numerous studies have explored the determinants of economic growth, research on the impact of tourism and democracy on economic growth remains debated in both developed and developing countries. Furthermore, studies examining the moderating role of democracy in the tourism–economic growth relationship are particularly scarce.
