Evaluation of a modified sequential P extraction protocol: Quantification of Fe(II)‐P as a separate phase in seven different freshwater sediments

Limnology and Oceanography: Methods, EarlyView.
Abstract Sequential phosphorus (P) extraction (SPE) is a well‐established and widely applied method for quantitatively and qualitatively determining the critical nutrient P in freshwater sediments. It allows the estimation of P bioavailability and facilitates the evaluation of the long‐term effects of eutrophication mitigation measures.

Modelling Wetting Collapse, Failure and Deposition of an Unsaturated Slope With Material Point Method

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The paper presents the modelling of unsaturated soils with the material point method (MPM), including the effect of wetting leading to the loss of strength and the volumetric collapse. The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an ...

Flexible Polyurethane Foams Reinforced With Recycled Waste Tire Material

Polymer Engineering &Science, EarlyView.
Ground tire rubber powder obtained through water jet pulverization mixed with PU foam possesses tunable mechanical and acoustic properties suitable for automotive, construction, and aerospace applications. ABSTRACT We explore the use of ground tire rubber (GTR) powder obtained through water jet pulverization (WJP), referred to as WJP‐GTR, and reveal ...

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

PLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...
