Messages for ultraviolet‐radiation protection to fair‐skinned populations

open access: yesJournal of the European Academy of Dermatology and Venereology, Volume 40, Issue 4, Page 576-582, April 2026.
This expert consensus summarizes messages for UV protection in fair‐skinned populations. Key messages include no sunbathing or tanning, no sunbeds. UV protection measures are to be used from UV index 3. Priority is given to shade and physical protection. Sunscreen with a strong SPF is to be used on uncovered areas.

On the Mean‐Field Limit of Consensus‐Based Methods

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4214-4240, 30 March 2026.
ABSTRACT Consensus‐based optimization (CBO) employs a swarm of particles evolving as a system of stochastic differential equations (SDEs). Recently, it has been adapted to yield a derivative free sampling method referred to as consensus‐based sampling (CBS). In this paper, we investigate the “mean‐field limit” of a class of consensus methods, including

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

PAMPS PolyHIPEs: The Role of Shape, Porosity, and Sulfonate Group Density on Metal‐Ion Adsorption From Water

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
This study demonstrates how pore architecture, shape, and sulfonate group density influence the adsorption of Zn2+, Fe3+, and Al3+ by PAMPS polyHIPEs. Beads and monoliths exhibit distinct transport behavior compared to commercial 77H resin. The results offer design guidelines for optimizing ion‐exchange polymers to improve performance in water ...
