Tracking the chemical life histories of spruce resin-beeswax mixtures through degradation experiments using reflectance-mode FTIR

open access: yesFrontiers in Materials
Within residue analysis, experimental degradation studies provide a critical bridge between pristine, modern-day reference materials and the altered residues encountered archaeologically. Here we report on outcomes of a 3-year burial experiment involving

Sustained Livestock Grazing Enhances Soil Organic Carbon Storage in Sub‐Arctic Grassland

open access: yesGlobal Change Biology Communications, Volume 1, Issue 4, December 2026.
We studied long‐term effects of grazing cessation on 34 grassland and heathland sites in Iceland. Grazing cessation was associated with lower SOC, nitrogen and root carbon in the top 10 cm of soil providing evidence for enhanced SOC in grazed land, showing that grazing is a climate change mitigation strategy.

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

open access: yesAdvanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an
