Groundwater is essential to urban water supplies throughout the world, but we do not understand how quantity and quality issues may jeopardize the ability of cities to meet their water needs. Here, we present a national analysis of both quantity and quality challenges facing China's urban groundwater supply security, using high-resolution groundwater depletion modeling and a recently compiled dataset detailing quality violations in drinking groundwater sources. We estimate that 180 cities (about half of the prefecture-level-and-above cities), accounting for 311 million urban residents, face at least one groundwater pressure between 2016 and 2021.

Architecture Knowledge Distillation for Evolutionary Generative Adversarial Network.

Int J Neural Syst

April 2025

NICE Research Group, School of Computer Science and Electronic Engineering, University of Surrey, Guildford, GU2 7XS, UK.

Generative Adversarial Networks (GANs) are effective for image generation, but their unstable training limits broader applications. Additionally, neural architecture search (NAS) for GANs with one-shot models often leads to insufficient subnet training, where subnets inherit weights from a supernet without proper optimization, further degrading performance. To address both issues, we propose Architecture Knowledge Distillation for Evolutionary GAN (AKD-EGAN).

Carbon quantum dots as efficient cocatalysts in Fenton-like processes: Preparation optimization and mechanistic insights.

J Hazard Mater

June 2025

Collaborative Innovation Center of Atmospheric Environment and Equipment Technology, Jiangsu Key Laboratory of Atmospheric Environment Monitoring and Pollution Control, School of Environmental Science and Engineering, Nanjing University of Information Science and Technology, 219 Ningliu Road, Nanjin

Carbon quantum dots (CQDs) are promising cocatalysts in Fenton-like technologies, leveraging hydrogen peroxide and boosting Fe generation and thereby expediting the advanced oxidation process. Although several studies have shown that the preparation affects the cocatalytic performance of the resulting CQDs, the precise correlation between the preparation and the cocatalytic efficiency is unclear. Here, we combine the batch experiments with the theoretical calculations to systematically explore how the parameters in electrochemical exfoliation preparation affect the cocatalytic performance of the as-prepared CQDs.

Advances in the Catalytic Mechanism of Metal Oxides for Lithium-Sulfur Batteries.

Small

March 2025

UNIST-NUIST Energy and Environment Jointed Lab, School of Environmental Science and Technology, Nanjing University of Information Science and Technology, Nanjing, 210044, China.

Lithium-sulfur (Li-S) batteries are one of the promising next-generation energy storage/conversion devices, considering their high energy density and low cost. However, the shuttle of polysulfides hinders the practical application of Li-S batteries, which leads to reduced cycling stability. Although chemical adsorption strategies have made significant progress in improving the cycling stability of Li-S batteries, the poor catalytic conversion ability of the polysulfide host results in an imbalance between chemical adsorption and catalytic conversion.

The Madden-Julian Oscillation (MJO) is the dominant mode of intraseasonal tropical atmospheric variability with far-reaching influences on global weather systems. During boreal winter, the MJO typically exhibits regular eastward propagation, whereas in summer, it displays more complex propagation characteristics, such as frequent stalling over the Indian Ocean. Here we show a threefold increase in the MJO residence time over the Indian Ocean during the Asian summer monsoon in recent four decades.

Key Laboratory of Ecosystem Carbon Source and Sink, China Meteorological Administration (ECSS-CMA), Nanjing University of Information Science and Technology, Nanjing, 210044, PR China; School of Ecology and Applied Meteorology, Nanjing University of Information Science and Technology, Nanjing, 21004

There is growing evidence for hormetic stimulation of Microcystis aeruginosa, a harmful algal bloom (HAB)-forming cyanobacterium, by subtoxic contaminant concentrations. Hence, the first meta-analysis of approximately 4000 dose responses was conducted to evaluate the underlying biological mechanisms, identify variation determinants, and reveal potential implications for algaecides effectiveness. Approximately 30 chemical contaminants caused significant stimulation (95% CI: 72-153%), which persisted in mixtures, regardless the level of mixture complexity.

Most of studies have mainly paid attention to the removal efficiency of a water treatment technology, while often overlooking the environmental and ecological toxicity. However, are water treatment technologies really environmental-/eco-friendly? If the as-generated chemicals are more toxic, it may lead to more severe secondary pollution. In this work, two novel integrated systems of Vis/CuO/HO (visible light-excited HO activation) and Vis/CuO/PS (visible light-excited persulfate (PS, NaSO activation) were designed and investigated fully, in which rhodamine B (RhB) was selected as the representative organic wastewater pollutant to assure the technology feasibility, although it has been studied widely.
