A sustainable and chemical-free strategy for superoxide generation based on rechargeable carbonaceous supercapacitors can enable effective pollutant abatement.
Demonstrating the complete defluorination of PFAS confirms PFAS mineralization and mitigated risk. The design of a UV/sulfite–electrochemical oxidation process achieved complete defluorination of various PFAS and removal of organics in aqueous film-forming foam.
Electricity trade between Ethiopia, Sudan and Egypt is proposed as a mechanism for alleviating Nile water disputes. Simulations show potential benefits, including reduced water deficits, lowered emissions and increased financial returns.
There is a pressing need to develop effective treatment technologies for 6PPD-quinone, a newly discovered micropollutant, given its prevalent presence in water. The proposed advanced oxidation of IO4− activation under solar light irradiation achieves efficient degradation of 6PPD-quinone at environmental concentration levels.
Chloramine is one of the most widely used disinfection methods for drinking water, and monitoring the complex reactions is still challenging. The proton transfer time-of-flight mass spectrometry developed here offers great sensitivity in measuring the kinetics of disinfectant decay in water.
Arsenic water contamination may affect spring water as well as water reservoirs around the world and requires the development of efficient and sustainable remediation technologies. A bioinspired porous membrane allows obtaining filtrated water with an As concentration below the recommendation from the World Health Organization.
The development of direct in situ disinfection methods in bottles is of vital importance for providing safe drinking water, especially in rural and disaster-stricken areas. Harvesting the electrostatic charges induced by walking can stimulate electroporation disinfection and provide readily available portable water for point-of-use applications.
This study demonstrates the evaluation of groundwater-dependent vegetation responses to changes in the depth to groundwater based on satellite-derived normalized difference vegetation index, a simple and practical approach that supports water and conservation management.
This work reveals that international agricultural trade eases water scarcity yet exacerbates inequity, disproportionately favouring more affluent populations, thus emphasizing the necessity for pro-poor policies for inclusive sustainable development.
Solar power desalination is a promising technology for clean water production in off-grid locations. Now a time-variant version of this technology overcomes the solar power intermittency that such desalination plants suffer from, hence reducing the need for costly batteries
Coagulation plays a crucial role in ensuring the safety of drinking water by removing natural organic matter. A comprehensive investigation of existing coagulation theories at the molecular functional group scale highlights the importance of the properties of natural organic matter on coagulation efficiency and provides valuable insights for predicting and achieving the efficient removal of pollutants by coagulation.
Coastal megacities, such as Shanghai and New York City, exhibit marked disparities in flood evacuation patterns for elderly residents. Risk-informed, strategic storm flood evacuation planning can significantly improve the overall performance of evacuee transfer for large coastal cities.
Half of irrigation expansion in the twenty-first century has taken place in water-stressed areas, offering a mixed picture for simultaneously achieving future food security, water sustainability and climate resilience in global agriculture.
Exceptional streamflow and soil moisture conditions now occur on a substantial share of global land area and are much more frequent than in pre-industrial times. This marks a notable transgression of the new planetary boundary for freshwater change.
This study introduces a self-supervised data assimilation model with a specifically designed loss function to generate a global total water storage anomalies (TWSA) product at a 0.5° spatial resolution, combining hydrological simulations with Gravity Recovery and Climate Experiment (GRACE) satellite measurements.
A robust and sustainable membrane anti-biofouling approach is needed to ensure long-term continuous and efficient water treatment. A dynamic membrane with sufficient and reliable active sites to load anti-biofouling agents in the membraneʼs internal structure and reload them after the release process is proposed with the goal of sustainable membrane biofouling control.
Although the contribution of microplastic fibres to pollution is well documented, less is known about the chemical composition of nanoplastics. The observation of plastic residues from textile washing shows the important contribution of water-insoluble oligomer particles to plastic pollution.
This study presents the probability of drought occurrence in various regions globally and demonstrates the pivotal role of moisture transport deficit. Assessing the contribution deficit of the dominant global moisture source to regional precipitation enhances drought predictability.
