Photogenerated fluphenazine radical cations for antiviral functionalization of polypropylene masks
Fluphenazine impregnated into nonwoven polypropylene masks is photoexcited to a radical cation, which inactivates viruses on the polymer surface without causing damage to the masks. Abstract The incorporation of photoactive molecules into polymeric substrates offers a compelling route to introduce advanced functionality while preserving the host ...

Improving Welding Behavior of ETPU Bead Foams by Surface Modification with Plasticizers
Tributyl citrate (TBC) and stearic acid (SA) modify ETPU beads through different diffusion mechanisms. TBC diffuses the bead structure directly after coating, whereas SA remains on the surface until melting and subsequent diffusion during heating. The resulting plasticization improves bead fusion, allowing RF processing at reduced temperature and ...

Soil health assessment using buried cotton underpants with the help of 1000 citizen scientists
Soil is a vital resource for life on Earth. Although many soils are degraded, societal awareness of soil‐related issues is limited. To highlight soil as a key resource and fascinating study system, we initiated a citizen science project together with 1000 participants investigating soil health across Switzerland using buried cotton underpants.

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

Roll‐to‐Roll Processing of Biodegradable Multilayer Barrier Packaging Structures
This work demonstrates that novel packaging materials built using biobased and biodegradable materials can be produced in pilot‐scale and converted into functional barrier packaging. The proposed structures are anticipated to make a strong impact in use‐cases where the risk of environmental littering is elevated, such as snacks and take away meals ...

Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

Topological Structuring of Adhesive Layers to Enhance Resistance against Interfacial Fracture
A hybrid bonding method that combines chemical affinity with mechanical interlocking is demonstrated. This approach uses a solution‐based technique to create a porous layer that strongly adheres to one substrate and templates a robust mechanical interlock with the other adherend. By tuning the pore geometry, crack propagation is effectively suppressed,
