Ecological characteristics of ?-cyclodextrin-bearing spherical PVA hydrogels as supports for microbial immobilization
Published on 2026-05-27 by Hirohito Yamasaki, Yui Iwamoto, Taiji Ito, Kimitoshi Fukunaga @NATURE
Abstract: Polymer Journal, Published online: 27 May 2026; doi:10.1038/s41428-026-01203-3We prepared a mixed-type PVA spherical hydrogel (PVA-mix-βCyD/HDI) was prepared, in which βCyD/HDI was accumulated and distributed at contents of 18–55 μmol g−1. The internetwork distance on the hydrogel surface increased from ~20 to 30 μm as the amount of β-CyD increased, as confirmed by SEM cross-sectional images. This trend is opposite to that observed for the homogeneously dispersed PVA-co-βCyD hydrog[...]
Our summary: The study investigates the ecological characteristics of β-cyclodextrin-bearing PVA hydrogels for microbial immobilization. A mixed-type PVA hydrogel was prepared, showing increased internetwork distance with higher β-CyD content. PhOH-degrading bacteria were effectively immobilized, enhancing degradation rates as β-CyD concentration increased.

Functional ice formation process
Patent published on the 2026-05-27 in EP under Ref EP4748802 by TERMINTER S R L [IT] (Interdonato Orazio [it])
Abstract: A functional ice formation process is provided comprising conveying water, defining its own concentration of calcium and/or magnesium carbonates, from a water network to a machine for making ice; freezing the water so as to obtain ice; refining the water, before or during the conveying, by reducing the concentration of the carbonates; and activating the water, following the refinement, by imparting antimicrobial capacity to the water by means of treatment with ozone and/or cold plasma; wherein t[...]
Our summary: The process involves conveying water with controlled carbonate concentrations to an ice-making machine. It includes refining the water to reduce carbonates and activating it with antimicrobial treatment. Additionally, the refinement process filters out particles and enriches the water with an inert gas to promote bicarbonate ion formation.

Microplastic contamination and the benefits of blue flag beach status
Published on 2026-05-06 by @OXFORD
Abstract: AbstractThis study aimed to determine the effect of “Blue Flag” status, an award that reflects a strong dedication to the sustainable management and protection of coastal resources, on the level of microplastic (MP) in beach samples. Quantitative determination of MPs was carried out at two beach locations in Greece, a Blue Flag beach in Glyfada, Attica, and beaches of the remote island of Leros without Blue Flag status. Samples of surface sand sampled at a maximum depth of 3 cm were taken a[...]
Our summary: This study evaluates the impact of Blue Flag status on microplastic levels at beaches in Greece. Samples from a Blue Flag beach showed significantly lower microplastic contamination compared to non-Blue Flag beaches. The findings suggest that Blue Flag designation contributes to better beach management and environmental protection.
