Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, Volume 45, Issue 3, Page 548-582, May/June 2026.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Boosting Photocatalytic H2O2 Generation via Interfacial Engineering in a 2D S‐Scheme Hydroxyethyl Cellulose‐Modified Graphitic Carbon Nitride/Bismuth Oxybromide Heterojunction

open access: yesSmall Structures, Volume 7, Issue 5, May 2026.
An S‐scheme heterojunction of hydroxyethyl cellulose‐modified g‐C3N4 and BiOBr drives efficient photocatalytic H2O2 generation. Interfacial engineering creates a built‐in electric field, facilitating charge separation while preserving stron\g redox potentials. This 2D architecture delivers a remarkable 5897 μM g−¹ h−¹ H2O2 production rate under visible

Protective Effect of Intracellular Compounds of Lactobacillus plantarum on Goat Sperm Quality During Cryopreservation

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Intracellular compounds from Lactobacillus plantarum were added to a goat sperm cryopreservation extender. A concentration of 20 µL/mL improved post‐thaw sperm quality, whereas higher concentrations (80–100 µL/mL) had detrimental effects. ABSTRACT Background Cryopreservation of sperm is a key strategy for preserving and transmitting the genetic traits ...

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

Identifying Food Packaging Migrants: Current Analytical Capabilities, Challenges, and Future Prospects

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The migration of intentionally and non‐intentionally added substances (IAS/NIAS) from food packaging into foodstuffs presents a significant challenge to consumer health and food safety. Accurate and comprehensive identification of these chemical migrants is therefore paramount.
