Enantioselective Determination of Chiral Fungicides in Food Samples Using Automated Dispersive Microextraction Coupled With UHPLC–MS/MS

Food Frontiers, Volume 7, Issue 2, March 2026.
The use of fatty acids and bio‐derived solvents eliminates the need for toxic solvents and, when combined with automated workstations, enables parallel sample processing, thereby improving extraction efficiency and reducing human error. ABSTRACT An enantioselective analytical method based on automated dispersive liquid–liquid microextraction (DLLME ...

Effects of Probiotic Supplementation on Symptoms and Microbiome Characteristics in Patients With Non‐Celiac Gluten/Wheat Sensitivity: A Randomized Controlled Double‐Blind Trial

Food Frontiers, Volume 7, Issue 2, March 2026.
This randomized, double‐blind, placebo‐controlled trial demonstrated that probiotic supplementation in individuals with non‐celiac gluten/wheat sensitivity improved tolerance to gluten reintroduction in nearly half of participants. The effect was associated with beneficial shifts in gut microbiome composition and function, including enhanced microbial ...

Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 193-217, March/April 2026.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...

Towards controlled liquid–liquid microextraction [PDF]

Journal of Fluid Mechanics, 2016
In a recent paper, Chu & Prosperetti (J. Fluid Mech., vol. 798, 2016, pp. 787–811) calculate the dissolution of a two-component droplet in an immiscible liquid. Here we discuss in what sense their results go much beyond the Epstein–Plesset solution of a dissolving single-component droplet and hitherto used approximations for dissolving ...
