Summary: The study assessed the recovery of phosphorus, nitrogen, methane, and extracellular polymeric substances (EPS) from aerobic granular sludge (AGS) wastewater treatment plants. About 30% of sludge organics are recovered as EPS and 25-30% as methane via alkaline anaerobic digestion (AD). It was found that a significant portion of phosphorus and nitrogen are present in EPS and can be recovered through chemical precipitation. Ammonium recovery is feasible from the AD centrate due to its high concentration.

Summary: In this study, a rapid and simple method for preparing porous carbon (PC) using microwave irradiation was proposed. Oxygen-rich PC was synthesized by irradiating potassium citrate and ZnCl2 in air. The use of ZnCl2 allowed for microwave absorption through dipole rotation, converting heat energy in the reaction system. Potassium salt etching was found to enhance the porosity of the PC. The resulting PC had a large specific surface area (902 m2/g) and exhibited significant specific capacitance (380 F/g) in the three-electrode system at 1 A/g. The assembled supercapacitor device based on PC-375W-0.4 showed energy and power densities of 32.7 W·h·kg-1 and 0.65 kW·kg-1, respectively, at a current density of 1 A/g. Even after 5000 cycles at a current density of 5 A/g, the PC retained 94% of its initial capacitance, demonstrating excellent cycle life.

Summary: Peatland open-water pools in different regions show coherent patterns of CO2, CH4, and DOM concentrations and compositions, which are driven by geographical and climatic factors such as temperature, precipitation, and vegetation cover. The concentrations of CO2 and CH4 are influenced by morphometry, vegetation cover, and the composition of DOM. In addition, the temporal variations of CO2 and CH4 are further influenced by seasonal changes in DOM composition, dissolved organic carbon and nutrient concentrations, as well as pH and oxygen levels. Geophysical constraints associated with local peat and pool characteristics play a significant role in determining DOM and greenhouse gases concentrations in peatland pools.

Summary: Peatland pools are dynamic aquatic ecosystems that contribute to biogeochemical cycles, but their response to environmental change is poorly understood. This study analyzed pool biogeochemical data from multiple locations to determine the drivers of carbon, nitrogen, and phosphorus dynamics in peatland pools. Climate and terrain were found to explain variations in pool biogeochemistry, with climate driving spatial differences in dissolved organic carbon concentration. The study also demonstrated the reactivity of peatland pools to local and global environmental change. These findings highlight the importance of understanding and monitoring peatland pool dynamics as potential climate sentinels.

Summary: As global warming increases the availability of permafrost organic carbon, methane-cycling becomes increasingly important in high-latitude ecosystems. This study examined samples from three high-latitude regions and found that physicochemical properties, especially pH, played a significant role in shaping the microbial communities involved in methane production and consumption. Geographic distance also influenced the diversity of these microorganisms, with dispersal limitation playing a role. Indicator species were identified to characterize different ecological niches. This research provides insight into the distribution of methane-cycling microbes in high latitudes under climate change predictions.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
