Emerging Heterogeneous Catalysis for Valorization of Biomass‐Derived Platform Molecules: The Systematic Review Toward Sustainable Biorefinery Applications

Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
Recent advances in heterogeneous catalysis for biomass valorization are highlighted, focusing on furfural, hydroxymethylfurfural (HMF), levulinic acid and glycerol conversion into fuels and chemicals. Metal oxides, zeolites, metal–organic frameworks (MOFs), porous organic polymers (POPs), carbons, and supported metals are compared, emphasizing acid ...

Capture of Saprolegnia parasitica Spores in Flow‐Through Aquaculture: First Observations

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Saprolegniosis, typically induced by oomycete Saprolegnia parasitica, is one of the most difficult pathogens in fish and other aquatic animals in freshwater systems. It is especially harmful for the endangered species landlocked salmon (Salmo salar m. sebago).

Depolymerisation of γ‐Valerolactone Organosolv Lignins with Unsupported Molybdenum‐Based Catalysts

ChemSusChem, Volume 19, Issue 3, February 2026.
Lignins from γ‐valerolactone organosolv fractionation were depolymerised in ethanol using unsupported molybdenum catalysts. Over 90% yields of low‐molecular‐weight lignin oil were obtained with minimal char formation, yields of the aromatic monomers being 7–16 wt%.

Valorization of Green Coconut Husk Powder for the Sustainable Production of Levulinic Acid

ChemistrySelect, Volume 11, Issue 6, 12 February 2026.
Green coconut husk powder, an abundant agroindustrial waste, is valorized into levulinic acid through aluminum sulfate catalysis. The sustainable process achieves 42.9% yield under mild conditions, contributing to circular bioeconomy principles and waste‐to‐chemical strategies.

DOC trail: soil organic matter quality and soil aggregate stability in organic and conventional soils [PDF]

, 2000
Conclusion Soil organic matter quality is affected by the agricultural systems of the DOC trial. System effects on the chemical composition, however, were smaller than those on the living organisms in soil and their functions.

Uncoupling human and climate drivers of late Holocene vegetation change in southern Brazil [PDF]

, 2018
In the highlands of southern Brazil an anthropogenitcally driven expansion of forest occurred at the expense of grasslands between 1410 and 900cal BP, coincident with a period of demographic and cultural change in the region.

Asymmetric Catalytic Hydrogenation toward a Value‐Added Chiral Building Block: Optically Active γ‐Butyrolactone Scaffold from Renewable and Synthetic Derived Feedstocks

European Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
This brief compendium summarizes the most successful asymmetric hydrogenation strategies for the preparation of chiral monocyclic γ‐lactone derivatives from keto acids and keto esters, with emphasis on their relevance for large‐scale production and high enatioselectivities. This article provides a brief compendium on the production of chiral monocyclic
