A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Biochar-enhanced anaerobic digestion of sewage sludge: Comparative performance and mechanistic insights

Water Research X
Anaerobic digestion (AD) is a sustainable approach for sewage sludge stabilization and energy recovery, but its efficiency is often limited by microbial imbalance and intermediate accumulation.

High‐Entropy Engineering and External Magnetic Field Modulation Synergistically Enhance the H2S Sensing Performance of Rare‐Earth Perovskite Ferrites

Advanced Science, EarlyView.
A novel high‐entropy perovskite oxide, (Gd0.2Tb0.2Dy0.2Ho0.2Er0.2)FeO3, was successfully synthesized for advanced hydrogen sulfide gas detection. By synergistically coupling high‐entropy‐induced local lattice distortion with weak magnetic field modulation, the tailored material generates abundant active sites. This innovative dual strategy dramatically

The bioavailability of cadmium from sewage sludge-amended soils. [PDF]

, 1999
PhDCadmium is a potentially toxic trace element present, at low concentrations, in a variety of environmental media. The processing of waste-waters produces sewage sludge, in which cadmium may be present at high concentrations.

Ammonification Process Is Limited by Transformation of Medium Molecular Weight Nitrogenous Organics but Not Hydrolysis of Proteins

Advanced Science, EarlyView.
A multi‐level analytical framework, integrating protein‐level persistence analysis, nontargeted HRMS formula tracking, peptide‐level proteomics, and targeted monomer quantification under varying redox conditions, together with FMO calculations reveal that ammonification is limited by medium molecular weight nitrogenous multimers.

Study of helminth eggs (Ascaris suum) inactivation by anaerobic digestion and electrochemical treatment [version 2; peer review: 1 approved, 2 approved with reservations]

Gates Open Research
Background The use of insufficiently treated wastewater or Faecal sludge in agriculture raises concerns because of the pathogen content. Helminth eggs (HE) are one of the most crucial pathogens for ensuring public health and safety.
