Sustainable levulinic acid production from inulin via hydrothermal conversion

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study investigates the hydrothermal conversion of inulin using potassium pyrosulfate to levulinic acid (LA). The Box–Behnken design approach was applied to optimize the conversion parameters and analyze the interactions influencing LA yield.

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Methods for the Assessment of Humic Substances Quality in Forest Soils

Soil and Water Research, 2006
This paper is focused on soil organic matter quality assessment in acid forest soils. Soil samples were collected in the Jizera Mountains region. Vegetation cover of sampling sites was formed by spruce or beech monocultures. Humus quality was assessed by

Selective Transfer Hydrogenation of Furfural to Isopropyl Levulinate: An In Situ One‐Pot Cascade Approach [PDF]

ChemSusChem
In this article, we applied a combination of metal (0.5 mol%) and acid (1 mol%) that functioned harmoniously to selectively convert a bio‐based starting material, furfural, into small oxygenates. We used a transfer hydrogenation reaction with isopropanol acting as both the reducing agent and the reaction medium. Isopropyl levulinate, a key intermediate

Phosphate‐Terminated Nb2C MXene as Efficient Catalyst for the Transformation of Glucose Into 5‐Hydroxymethylfurfural With 3077 h−1 Turnover Frequency

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
A new phosphate‐terminated Nb2C MXene has been developed as an efficient heterogeneous catalyst to convert glucose into 5‐hydroximethylfurfural. Characterization of the Nb2C‐PO4 catalyst has proven the presence of phosphate and the integrity of the MXene laminar structure.

Humic Acids and EDTA Added to Marine Sediments Improve eDNA Detectability

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Environmental DNA detectability in sediments increased with the addition of humic acid sodium salts prior to lysis. The addition of EDTA before lysis yielded a similar improvement, suggesting that various chelating agents can enhance eDNA recovery and detection. ABSTRACT Sediments are complex and challenging matrices for DNA detections.

Harnessing Acoustic Cavitation Energy for the Selective Degradation of Impurities in Glucose Syrup

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
The energy released during the implosion of acoustic cavitation bubbles can be harnessed and selectively transferred to a target solute, enabling its specific decomposition without degrading other solutes present in the solution. This proof of concept was demonstrated in the degradation of impurities present in trace amount in glucose syrup.

Carbon Sequestration in Soil Humic Substances Under Long-Term Fertilization in a Wheat-Maize System from North China

Journal of Integrative Agriculture, 2014
The changes in humic substances (HS) is fundamental in detecting soil carbon sequestration mechanisms in natural and cultivated environments. Based on a long-term trial, the amounts of water dissolved substances (WSS), humic acid (HA), fulvic acid (FA ...
