“…The mobile phase for LC-MS consisted of water with 0.1% acetic acid (solvent A) and acetonitrile with 0.1% acetic acid (solvent B). 1 H nuclear magnetic resonance (NMR) spectra were acquired using a Bruker AV III 500 MHz spectrometer, and the data were analyzed using MestReNova software (version 8.1.1). The chemical shifts in the 1 H NMR spectra are expressed in units of parts per million relative to tetramethyl silane (TMS).…”

Selective sensing and removal of toxic heavy metals from water are highly essential since their presence poses significant health and environmental hazards. Herein, we designed and synthesized a novel fluorescent nonconjugated organic polymer by strategically incorporating two key functional groups, namely, a dansyl fluorophore and dithiocarbamate (DTC). Different characterization techniques, including 1 H nuclear magnetic resonance (NMR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDAX), Fourier transform infrared (FTIR), and fluorescence spectroscopy, were performed to understand its structure and material properties. The quantum yield of 4.72% and its solid-state fluorescence indicate that it has potential for various applications in several technological and scientific domains. In this study, we investigated a specific application involving the detection and elimination of heavy metals from water. Interestingly, the presence of dansyl and DTC moieties demonstrated remarkable selectivity toward Cu 2+ , Co 2+ , Ni 2+ , Fe 3+ , and Fe 2+ sensing, displaying distinct color changes specific to each metal. Cu 2+ resulted in a yellow color, Co 2+ showed a green color, Ni 2+ displayed a pale yellowish-green color, and Fe 2+ /Fe 3+ exhibited a brown color. The LOD (limit of detection) for each metal was obtained in the nanomolar range by using a fluorescence spectrometer and the micromolar range from UV−visible spectra: 13.27 nM and 0.518 μM for Cu 2+ , 8.27 nM and 0.581 μM for Co 2+ , 14.36 nM and 0.140 μM for Ni 2+ , 14.95 nM and 0.174 μM for Fe 2+ , and 15.54 nM and 0.33 μM for Fe 3+ . Moreover, the DTC functionality on its backbone facilitates effective interaction with the aforementioned heavy metals, subsequently removing them from water (except Fe 2+ and Fe 3+ ), validating its dual functionality as both an indicator and a purifier for heavy metals in water. The polymer exhibited a maximum adsorption capacity of 192.30 mg/g for Cu 2+ , 159.74 mg/g for Co 2+ , and 181.81 mg/g for Ni 2+ . Furthermore, this approach exhibits versatility in crafting fluorescent polymers with adjustable attributes that are suitable for a wide range of applications.

The water–energy–food (WEF) nexus is drawing much attention in scholarly literature as a novel alternative to address complex resources and achieve resource security. The aim of this study is to analyze and review existing nexus studies to investigate the current status of nexus research worldwide. This study used a narrative review approach to provide a comprehensive overview on the WEF nexus using a variety of databases. It is indicated that the majority of studies in Asia and Africa focused on the water–energy–food (WEF) nexus. China and Brazil had the largest nexus research. Based on the existing literature, most of attention has been paid to food production. However, food consumption patterns and dietary change are rarely evaluated, and there is a lack of study on impacts of dietary change on the WEF nexus. Moreover, there is a lack of frameworks for the evaluation of the WEF nexus under dietary change scenarios. The major challenge of the nexus approach is data availability in crop production, which can be solved by using remote sensing data. There is a lack of standard and conceptual frameworks for nexus assessment and, then, an essential need to provide a new holistic and standard approach that be applicable worldwide to increase connections between researchers and decision makers, as well as the applicability of nexus approaches. Future research must couple the development of a holistic standard approach with experimental tests in different areas, involving interdisciplinary research groups able to carry out all the experimental activities, the numerical simulations, and the statistical analyses of climatic time series (in a climate change perspective) indispensable to demonstrate the real benefits of using a WEF-derived nexus approach.

The interplay of water resources with economic and social spheres involves a reciprocal feedback mechanism. Investigating the adaptation status of the composite system consisting of the two is crucial for promoting sustainable and coordinated development. Based on the current situation in water resources and economic-social development in Hunan Province, China, a evaluation system with 22 indicators was established. The quantitative analyses were conducted using improved coupling coordination models, harmonious development models, and OECD models to assess the adaptability of 14 cities (prefectures) in Hunan Province. The results indicated the following: 1) Recently, water resources subsystems (WRS) development index in various cities (prefectures) in Hunan Province has shown signs of improvement, while the economic-social subsystems (SES) development index has exhibited a palpable upward trend. 2) Currently, the coupling coordinative degree between the two subsystems has reached a state of coupling coordination, but spatial differences between north and south regions still existed. 3) The lagging development trend in Hunan Province indicates that the growth rate of WRS has surpassed that of SES. However, the harmonious development capacity of the composite "Water-Economy-Society" system remains relatively low, whilst the contradiction between economic-social development and water resource scarcity has not been effectively alleviated.
