A Plant‐Based Platform for the Production of Bark Beetle Pheromones

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2442-2456, April 2026.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

Applications of Solid-Phase Microextraction and Gas Chromatography/Mass Spectrometry (SPME-GC/MS) in the Study of Grape and Wine Volatile Compounds

open access: yesMolecules, 2014
Volatile compounds are responsible for the wine “bouquet”, which is perceived by sniffing the headspace of a glass, and of the aroma component (palate-aroma) of the overall flavor, which is perceived on drinking.

Advances in Automated Sample Preparation for Gas Chromatography: Solid-Phase Microextraction, Headspace-Analysis, Solid-Phase Extraction

open access: yes, 2016
Despite the widespread use of more and more effective detection technologies such as tandem-mass spectrometry, it is becoming increasingly clear that proper sample preparation is still the key to a successful analysis. The most important demands are thereby complete automation, sensitivity, reliability, economic efficiency and also implementation of ...
