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.

From freshness to preservation: insights into processing and storage impacts on purple passion fruit volatilome

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2139-2153, 15 March 2026.
Abstract BACKGROUND Purple passion fruit is highly appreciated for its distinctive sweet flavour, low acidity, and aromatic profile, making it a desirable choice for fresh consumption and juice production. To ensure microbiological safety and extend shelf life, juice products typically undergo thermal pasteurization, which can alter their ...

Towards controlled liquid–liquid microextraction [PDF]

open access: yesJournal 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 ...
