A Comparative Biochemical Study of Oleate Hydratases

open access: yesChemBioChem, Volume 27, Issue 15, 14 August 2026.
Four oleate hydratases (Ohys) from diverse homologous families (HFams) were characterized side‐by‐side in terms of expression levels, oligomeric state, flavin adenine dinucleotide (FAD) affinity, thermostability, and activity. A general favorable effect of the reduction of FAD to FADH2 for Ohy activity was demonstrated, with (R)‐10‐hydroxystearic acid (

Efficient Solketal Synthesis via Acetalization Using Sulfonated Carbon From Lavender Leaf Waste After Essential Oil Extraction

open access: yesChemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Sulfonated carbon catalysts were synthesized from lavender leaf waste after essential oil extraction via hydrothermal carbonization (HTC). Under mild, low‐energy conditions, the catalyst achieved 97% glycerol conversion and 98% solketal selectivity. This approach valorizes agricultural residues and crude glycerol from biodiesel production, contributing

Coherence Between Climate and Land Use Policies of the European Union, Brazil, and Indonesia: A Primer to Analyze Potential GHG Leakage

open access: yesEnvironmental Policy and Governance, Volume 36, Issue 4, Page 871-886, August 2026.
ABSTRACT Incoherence between national land use policies may weaken climate mitigation efforts by creating conditions under which agricultural and forestry production and GHG emissions are displaced across borders (leakage). Coherence depends on constellations and prioritization of national policy aims in land use (production) and climate (conservation).
