Etude par chromatographie en phase gazeuse de substances volatiles issues du bois de chêne

OENO One, 1987
Une méthode de dosage par chromatographie en phase gazeuse de substances cédées par le bois de chêne (furfural, méthyl-5 furfural, alcool furfurylique, cis et trans β-méthyl γ-octalactone) est mise au point. On suit l'évolution de ces substances dans les

Microwave‐Assisted Recycling of Lithium‐Ion Batteries: Linking Process Optimization to Volatile Organic Compounds and Fluorinated Gases Emission Mitigation

Battery Energy, Volume 5, Issue 2, March 2026.
Microwave‐assisted recycling of black mass from spent lithium‐ion batteries was optimized through a Design of Experiments approach, linking heating parameters to lithium recovery efficiency and volatile emissions. Combining GC–MS and multinuclear NMR analyses, the study identifies key conditions minimizing hazardous fluorinated and organic gas ...

Assessment of Metabolites in Noni Fruit Slurry Fermented With Four Non‐Saccharomyces Yeasts

Food Frontiers, Volume 7, Issue 2, March 2026.
Dried noni fruit slurry (DNFS) was fermented for 14 days with selected non‐Saccharomyces yeasts. GCMS, HPLC and amino acid analysis showed that Pichia kluyveri Frootzen and Williopsis saturnus NCYC22 grew well, reduced off‐flavor fatty acids, generated fruity aroma compounds and preserved total phenolic content. ABSTRACT Noni products often suffer from

Chemical Characterization of Postindustrial Recycled Polyethylene Terephthalate Obtained From Multilayer PET/PE Sheets: A Baseline Study on Safety Aspects

Packaging Technology and Science, Volume 39, Issue 3, Page 257-270, March 2026.
PET trays pose recycling challenges due to multilayer structures with polyethylene (PE) tie‐layers and barrier materials. In this study, a delamination process using a hot alkaline solution was applied to postindustrial multilayer PET/PE thermoforming waste to recover PET flakes and produce sheets.

Progress in Surface‐Enhanced Raman Scattering‐Based Volatile Organic Compounds Detection: Materials, Application, and Prospects

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.

Indanone Building Blocks From Lignin Related C9‐Platform Molecules

ChemistrySelect, Volume 11, Issue 10, 11 March 2026.
ABSTRACT Lignin‐based aryl 3‐hydroxypropanones were converted into indanones via a domino dehydration/Nazarov cyclization in the presence of a superacid. The cyclization was studied in detail, and the resulting indanones were engaged in two postfunctionalizations: a reduction/elimination domino sequence and a ring expansion. Lastly, the method has been

Electrocatalytic Reduction and Oxidation Conversion of Plant Biomass

Small Structures, Volume 7, Issue 3, March 2026.
This review therefore establishes a unified “compound–catalyst–conversion” paradigm, systematically categorizing and analyzing electrocatalytic oxidation and reduction pathways for the three major classes of plant‐derived components—aromatics, aliphatics, and terpenoids—to provide a clear navigational map for the field.
