• Antimicrobial properties of copper-based shape-memory alloy wires coupled to hydrogen peroxide solutions for endodontic treatments · 2026

  Résumé de la publication : Copper-rich shape memory alloys (Cu-SMAs) combine unique mechanical properties and catalytic redox activity, supporting the development of advanced endodontic files to improve patient treatments. This study evaluated the bactericidal activity of CuAlBe and CuAlNi wires combined with H2O2-containing solutions against Enterococcus faecalis,…

• Knickpoint Morphology in Homogenous Substrates Controlled by Sediment Cover and Base‐Level Fall Rate · 2026

  Résumé de la publication : Knickpoints are prominent geomorphic features (the most well-known being waterfalls) defined as the transition between upstream relict topography and downstream topography adjusted to boundary conditions. Despite being localised within rivers (10s of m), knickpoints profoundly control landscape evolution in the basin where…

• Modelling and understanding knickpoint dynamics in homogenous substrates. · 2026

  Résumé de la publication : In fluvial environments, knickpoints are key geomorphological landscapes exerting a disproportionate control on landscape evolution. Their influence extends both along the fluvial network and into adjacent hillslopes through coupled channel–hillslope processes. Despite this, previous studies focus on individual elements of knickpoint retreat…

• Tracing Plastic Degradation in Soils Using Copper Isotopes: Novel Insights from Laboratory Experiments · 2026

  Résumé de la publication : Global plastic production now exceeds 400 million tons per year and continues to increase, despite plastics being ubiquitous and pervasive in every environmental compartment. Soils are increasingly recognized as major sinks for macro-, micro- and nanoplastics. The presence of plastic in soils…

• Application of a coupled model of channel width evolution and multi-grain size sediment transport to predict the full signal (all grain sizes) of sediment cascades preserved in stratigraphy · 2026

  Résumé de la publication : Catastrophic sediment release in fluvial systems is largely driven by landsliding that occurs naturally in mountain belts during extreme events, such as earthquakes or storms. Sediments are routed through the river system until they are stored either permanently in alluvial fans and…
