Electrochemical Chlorination of Levulinic Acid

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Levulinic acid is a cellulose‐derived, sustainable feedstock with significant potential for use in renewable, carbon‐based polymer and chemical synthesis. In this work, electrochemical chlorination has been investigated as a method for preparing chlorinated levulinic acid derivatives, which can serve as valuable intermediates for the synthesis

Interaction Among Microbiota, Chemical Composition, and Quality Variations in Coffea arabica Across Altitudinal Gradients During Wet Processing

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Fermentation significantly altered the dominant bacterial genera from Sphingomonas and Pleomorphomonas (before fermentation) to Weissella and Lactobacillus (after fermentation), while Cladosporium and Fusarium remained the dominant fungal genera. Notably, non‐volatile compounds in de‐pulping coffee beans and volatile compounds of roasted coffee beans ...

Evaluating Stabilizers Effects on Aroma Release Dynamics in Ice Cream: A PTR‐ToF‐MS Analysis

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Capturing the dynamic volatilome of frozen matrices during phase transitions remains an analytical challenge, typically requiring invasive sampling. This study employs proton transfer reaction time‐of‐flight mass spectrometry (PTR‐ToF‐MS) as a rapid, noninvasive technique that directly samples headspace volatiles without preconcentration to ...

Heterogeneous Organocatalytic Synthesis of Propargylic Esters Using a Polymer‐Supported N‐Heterocyclic Carbene

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
A vinyl addition polynorbornene (VA‐PNB)‐supported N‐Heterocyclic carbene precatalyst is successfully used in the metal‐free coupling of terminal alkynes, carbon dioxide, and chlorides toward propargylic esters. The conversion of carbon dioxide into high‐value chemical scaffolds is a central challenge in modern green chemistry. In this study, we report

Exploration of Antifungal and Immunomodulatory Potentials of a Furanone Derivative to Rescue Disseminated Cryptococosis in Mice [PDF]

Scientific Reports, 2017
AbstractCryptococcus neoformans infection is quite complex with both host-pathogen interaction and host immune profile determining disease progress and therapeutic outcome. Hence in the present study, the potential utility of (E)-5-benzylidenedihydrofuran-2(3 H)-one (compound-6) was explored as an effective anticryptococcal compound with ...
