Improving the Economics of Sustainable Aviation Fuels: System‐Level Analyses and Perspective

open access: yesChemSusChem, EarlyView.
A coproduction strategy is developed to address the economic and environmental limitations of sustainable aviation fuel (SAF) production. Using lignocellulosic biomass, the integrated process coproduces SAF, adipic acid, and furfural. Techno‐economic and life‐cycle analyses reveal improved profitability and a substantial reduction in carbon emissions ...

Petrogenetic and geochemical characteristics of some auriferous granitoids in the Kumasi Basin, Ghana: Implications for geodynamic settings and controls of orogenic gold mineralization in the Edikan Gold Mine

open access: yesDeep Underground Science and Engineering, EarlyView.
The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.
