Water scarcity has become one of the serious global challenges threatening urban water security. To systematically understand the utilization of water resources in cities, this study established a novel comprehensive accounting framework of urban water resources based on three dimensions: "the entire city, sectoral level, and intersectoral interactions". To make this accounting framework that can be applied to the majority of cities, a method for compiling input-output (IO) tables at the general prefecture-level city scale was proposed to obtain the needed core data.

As the most popular liquid metal (LM), gallium (Ga) and its alloys are emerging as functional materials due to their unique combination of fluidic and metallic properties near room temperature. As an important branch of utilizing LMs, micro- and submicron-particles of Ga-based LM are widely employed in wearable electronics, catalysis, energy, and biomedicine. Meanwhile, the phase transition is crucial not only for the applications based on this reversible transformation process, but also for the solidification temperature at which fluid properties are lost.

The recent discovery of non-classical crystal nucleation pathways has revealed the role of fluctuations in the liquid structural order, not considered in classical nucleation theory. On the other hand, classical crystal growth theory states that crystal growth is independent of interfacial energy, but this is questionable. Here we elucidate the role of liquid structural ordering in crystal nucleation and growth using computer simulations of supercooled liquids.

Long-term storage of aerobic granular sludge (AGS) may lead to granule inactivation and disintegration. Granule recovery in both structure and activity is important for scale-up and stability of AGS, but information about the structure recovery of stored AGS is limited. In addition, whether short-term exogenous N-acyl-homoserine lactones (AHLs) regulations could accelerate the granule recovery and sustain positive effects on AGS is unknown.

Urban agglomerations are a primary spatial focus of socioeconomic activity and inherently include large volumes of embodied water. We have applied the concept of water metabolism health to comprehensively evaluate the overall operation of water systems in urban agglomerations and propose an innovative assessment framework. In particular, we constructed a water metabolism network (WMN) model to simulate a water system in which different cities and sectors are integrated, combining a newly compiled multiregional input-output (MRIO) table of water flow with ecological network analysis (ENA).

Meeting increasing food demands in an environmentally sustainable manner is a worldwide challenge. Applying life cycle analysis to different scenarios, we show that a 47-99% reduction in phosphorus emissions, nitrogen emissions, greenhouse gas emissions, bluewater consumption and cropland use is needed for China's food production in 2030 to be within national and provincial environmental boundaries. Basic strategies like improving food production efficiency, optimizing fertilizer application, reducing food loss and waste and shifting diets are currently insufficient to keep environmental impacts within national boundaries-particularly those concerning nitrogen.
