Combined Foaming and Surface Structuring of Polymers With Supercritical Carbon Dioxide (scCO2) Applying an Incomplete Saturation Strategy

Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.
Combined foaming and structuring of polymer samples by processing with supercritical CO2 leads to nano‐ and microstructured surfaces on top of perfectly white polymer sheets. ABSTRACT Supercritical carbon dioxide (scCO2) is a widely applied solvent utilized in many physical–chemical processes, including the foaming or structuring of polymers.

Comparative 1H NMR Metabolomics Between Scandinavian Propolis and Australian Propolis: The Quest to Identify Radical Scavenging Compounds

Magnetic Resonance in Chemistry, Volume 64, Issue 4, Page 438-450, April 2026.
Propolis from Scandinavia and Australia was chemically characterized using 1H NMR spectroscopy and multivariate modeling. Recursive partial least squares revealed spectral features associated with radical scavenging activity, and STOCSY enabled identification of the key phenolic compounds underlying these bioactive features. ABSTRACT Propolis from Apis

Biomodification of dentin collagen with hydroalcoholic propolis extract: Impact on resin–dentin adhesion

European Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract This in vitro study evaluated the effect of hydroalcoholic propolis extract (HPE) as a collagen cross‐linking agent for preserving the dentin–adhesive interface. Dentin beams from human third molars were demineralized with 10% phosphoric acid and assigned to five treatments: distilled water (control), 6.5% grape seed extract (GSE), and HPE at ...

Detecting a Small Hive Beetle's eDNA in Honeybee Colonies

Journal of Applied Entomology, Volume 150, Issue 3, Page 277-284, April 2026.
ABSTRACT Early detection is important to limit the spread of invasive species. Molecular diagnosis using eDNA can be useful in this regard, but the sensitivity is often unknown. This holds true for small hive beetles (SHB), which are parasites of honeybee (HB) colonies and continue to spread globally.

Potential for Natural Antimicrobials, Including Mushroom Chitosan, to Control Shiga‐Toxigenic Escherichia coli in Ground Beef

Journal of Food Safety, Volume 46, Issue 2, April 2026.
This study evaluated the antimicrobial activity of 11 natural agents against eight STEC serotypes by determining their MIC and MBC at different pH and temperature conditions. Five agents demonstrating the strongest inhibitory activity in vitro were then tested at various concentrations in beef burgers inoculated with Escherichia coli O157 and stored ...

Propolis‐Based Hybrid Nanoflowers as Multifunctional Nanozymes: Structural Integration of Polyphenols for Enhanced Catalytic and Antioxidant Activity

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT Propolis is a polyphenol‐rich natural resin with well‐documented antioxidant activity; however, its practical application is restricted by poor aqueous solubility and limited stability. Herein, propolis‐based organic–inorganic hybrid nanoflowers (Prp‐Nfs) were synthesized by integrating a propolis extract into a Cu3(PO4)2·3H2O matrix under ...
