Sorbent-Based Microextraction Combined with GC-MS: A Valuable Tool in Bioanalysis

open access: yesChemosensors
Sample preparation is broadly recognized as the most critical, time-consuming, and error-prone step of a bioanalytical workflow. Over the years, the development of pretreatment methods aimed at the isolation and preconcentration of the target analytes ...

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

open access: yesJournal 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 ...

Effect of carcass storage condition on searcher efficiency trials for conservation detection dogs

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
We investigated the influence of storage condition on bat carcass odor through chemical analysis. Additionally, we tested the detectability of 3 carcass storage conditions through searcher efficiency trials with conservation detection dogs. Only 20% of the chemicals observed were shared across all 4 carcass storage conditions.

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5689-5702, August 2026.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

Attraction of nocturnal scarab beetles by unusual floral volatiles in a Banksia (Proteaceae) with functionally diverse pollinators

open access: yesPlant Biology, Volume 28, Issue 5, Page 1454-1466, August 2026.
Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...

Sustainable Ball Milling‐Assisted Synthesis of Bread Waste‐Derived Highly Porous Carbons for Adsorption‐Based Applications

open access: yesChemPhysChem, Volume 27, Issue 13, 14 July 2026.
A simple strategy is proposed to convert food waste such as dry bread into highly porous carbons that can be used for catalysis and adsorption‐related applications. Namely, a fast ball milling of dry bread and a mild activation agent, followed by carbonization at 800°C, is used to obtain porous carbons with surface areas up to 2400 m2/g.

In Situ Formed Organic Ion-Associate Liquid-Phase Microextraction without Centrifugation from Aqueous Solutions Using Thymol Blue and Estrogens

open access: yesSeparations
In this study, we present a method for ion-associated liquid phase (IALP) separation and concentration of analytes from an aqueous matrix into an IALP formed in situ by the charge neutralization reaction of organic cations and anions, without ...

Microextraction methods

open access: yes, 2012
Accurate, rapid and economic qualitative and quantitative analysis of trace amount substances in biological, environmental and food products is an important issue. Mostly, such substances must be taken from the matrix (separation) and concentrated (enrichment) before determining with analytical equipment. For these processes liquid-liquid, solid-liquid
