Summary: In this study, a combined in silico and experimental approach was used to investigate the extraction of furfural and HMF in aqueous-organic biphasic systems. The experimental data were found to be in good agreement with the predictions from the COSMO-RS model, and a selective extraction of furfural was demonstrated using an additional extraction step. The molecular nature of preferential furfural extraction was rationalized using COSMO-RS sigma-profile analysis.

Summary: Compression ignition (CI) engines using fossil diesel are major contributors to air pollution. Previous studies have attempted to replace fossil diesel with biofuels to reduce carbon dioxide emissions, but the performance has been sub-standard. Researchers have introduced hydrogen with biofuels in an attempt to improve engine performance. This study examines the effects of hydrogen addition with biodiesel/vegetable oil from various sources in CI engines.

Summary: Supercritical water gasification is a process for converting wet biomass into syngas without the need for energy-intensive pre-drying, aiming to obtain syngas rich in hydrogen. Studies have shifted from using model compounds to real biomass feedstock, investigating factors influencing hydrogen yields and the relationship between biomass components and hydrogen yields.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
