Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

Plant Availability of Phosphorus From Sewage Sludge Ash‐Based Fertilizers and Its Relationship to Phosphorus Extractability

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Sewage sludge ash (SSA) is a potential phosphorus (P) source for fertilizers, but untreated SSA (USSA) often shows low plant availability of P. To increase P availability, sodium additives can be applied before sewage sludge incineration or during thermochemical SSA posttreatment, as this leads to the formation of CaNaPO4.
