“…Network diffusivity, combined with offering sorption sites for pollutants, are key for the use of nanocellulosic absorbent filters in environmental engineering applications , and oil and gas production . Secondary surface modification, cross-linking, or hybridization with other natural or synthetic polymers enables pollutant-specific membrane designs, with enhanced sorption capacities and rates, as well as mechanical and structural integrity, e.g., to withstand water flow for an extended time. ,,− The sorption of organic contaminants from water has also been demonstrated with modified nanocellulose matrices. The inherent hydrophilicity of nanocelluloses should be reduced to improve the affinity of the material for hydrophobic compounds.…”

Modern technology has enabled the isolation of nanocellulose from plant-based fibers, and the current trend focuses on utilizing nanocellulose in a broad range of sustainable materials applications. Water is generally seen as a detrimental component when in contact with nanocellulose-based materials, just like it is harmful for traditional cellulosic materials such as paper or cardboard. However, water is an integral component in plants, and many applications of nanocellulose already accept the presence of water or make use of it. This review gives a comprehensive account of nanocellulose–water interactions and their repercussions in all key areas of contemporary research: fundamental physical chemistry, chemical modification of nanocellulose, materials applications, and analytical methods to map the water interactions and the effect of water on a nanocellulose matrix.

Liquid‐phase exfoliation of bulk crystals of layered materials, held together by weak interlayer van der Waals forces, is an ideal platform for scalable synthesis of nanosheets. However, it is mandatory to substitute existing solvents, regrettably displaying severe limitations due to toxicity. Here, dimethyl 2‐methylglutarate (Rhodiasolv Iris) is validated for efficient liquid‐phase exfoliation of selected van der Waals materials, namely, MoS2, WS2, GeSe, and graphite. Here, we show that Iris‐assisted liquid phase exfoliation provides high yield (up to 52%) of flakes of 2D materials with aspect ratio as high as 500. Considering the various advantages of Iris over the state‐of‐the‐art solvents, including the absence of toxicity and its biodegradability, this work opens new possibilities for the ecofriendly production of 2D materials and for their extensive usage in industrial processes hitherto semi‐unexplored, owing to the toxicity of state‐of‐the‐art solvents (including the production of drinkable water or fruit juice concentration). Accordingly, the validation of Iris for sustainable liquid‐phase exfoliation of van der Waals crystals has intrinsic outstanding potential commercial impact. Moreover, here the values of the surface tension, Hansen solubility parameter, and viscosity of Rhodiasolv Iris are reported for the first time, which will be relevant also for any other sustainable process based on this new green solvent.

With rapid urbanization and industrialization in China, the demand for mineral products and subsequent water consumption have significantly increased, posing challenges to sustainable economic growth due to escalating water scarcity. Few studies have explored the nexus between water use and economic output from the enterprise perspective. This study focuses on the metallic and non‐metallic mineral products sector, quantifying the nexus between water consumption and economic output at the enterprise level, analyzing the heterogeneity of water consumption elasticity of economic output across different regions and sub‐sectors, and identifying key sub‐sectors within each region that are highly dependent on water consumption. The results indicate that for the metallic and non‐metallic mineral products sector, a 1% increase or decrease in water consumption leads to a corresponding increase or decrease in economic output by 0.096%. Water consumption elasticity of economic output varies from 0.056 to 0.131 according to the regions. And it ranges from 0.048 to 0.104 for different sub‐sectors. This study identifies regions and sub‐sectors where economic output is highly dependent on water resources. The findings may help tailor policies to measure the value of water, especially in the context of potential water shortages.
