Abstract Pyrogenic carbon is widely regarded as a component of soil organic carbon, yet how small amounts of vertically redistributed pyrogenic carbon influence organo mineral interfaces in subsoils remains unresolved. Here we combine a ten year field ageing experiment along a 200 cm calcareous soil profile in China with electrochemical assays, spectroscopy and nanoscale microscopy to link pyrogenic carbon electron transfer capacity to mineral association.

Abstract Background: The hospital-wide “One Bed” model poses potential risks in cross-departmental patient care, affecting nursing quality and patient safety. However, systematic evaluation and improvement strategies for these risks remain limited. Objective: This study aimed to apply Failure Mode and Effects Analysis (FMEA) to identify and improve nursing quality risks under the “One Bed” model, providing actionable strategies for proactive risk management in cross-departmental patient care.

Reduction of hexavalent chromium by compost-derived dissolved organic matter† Compost-derived dissolved organic matter (DOMC) is a heterogeneous assemblage of different redox-active organic molecules. We hypothesize that DOMC can interact with Cr(VI) and reduce it to Cr(III), thereby influencing the dynamics of Cr(VI) in soil and aquatic environments.
