Green Refrontierisation: Critical Cartographies of the Hydrogen Rush in Africa
Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.Short Abstract This article provides a critical cartographic analysis of the green hydrogen (GH2) maps present within the reports of European states, lobby groups and investment bodies to examine the role of geographical knowledge in the production of low‐carbon energy frontiers. It identifies three spatio‐political strategies present within these maps

Pyrite–Coal Depressants Interactions During Coal Reverse Flotation
This work investigates coal desulfurization by using reverse flotation. In this method, pyrite (the only source of sulfur in the studied coal) was separated from the meta-bituminous coal by using three different coal depressants (starch, dextrin and ...
