The grapevine microbiota: A review on the possible impacts of plant protection programs on phyllosphere microorganisms

open access: yesAnnals of Applied Biology, EarlyView.
This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

open access: yesAdvanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

Bentonite clays as aflatoxin B1 adsorbents [PDF]

open access: yes, 2023
In this study three bentonite clays (bentonite from deposit Beretnica in Republic of Serbia, commercial bentonite and gray clay from Šipovo deposit in Bosnia and Herzegovina) were investigated as adsorbents of aflatoxin B1 (AFB1). In a single in vitro AFB1 adsorption experiment, all three bentonites showed high adsorption efficiency for AFB1 at pH 5 ...
