“…Secondly, from the perspective of the coordination degree, the results for the static coordination degree of the YREB in this paper are consistent with the research conclusions of Han et al and Lv et al [70,71]. The reason for this may be that, on the one hand, with the YREB beginning to carry out NU construction, good progress has been made in all aspects of the ecological environment, which is conducive to the promotion of the sustainable development strategy.…”

For sustainable development of the world, it is crucial to solve the problems related to water environment pollution, water shortage, and the inefficient utilization of water resources during the process of urbanization in developing countries. At present, scholars mainly focus on the measurement of new urbanization (NU) and the water ecological civilization (WEC) level and the coordination relationship between NU and ecological civilization. However, there have been few studies on the coordination relationship between NU and WEC and its driving factors. We take the Yangtze River Economic Belt (YREB) in China as a case study, construct the indicator system of NU and WEC, analyze the current situation of NU and WEC in the YREB, and study the coordination state of NU and WEC in the YREB from 2011 to 2020 by using a state coordination function. We further examine the factors driving the coordination of NU and WEC by employing a two-way fixed-effects model. The results show the following: (1) The growth rate of NU and WEC in the YREB shows a fluctuating upward trend, where there is significant heterogeneity between the upper reaches, the middle reaches, and the lower reaches of the YREB. (2) The static coordination degree of NU and WEC in the YREB shows a trend of fluctuating upwards and then falling, and the dynamic coordination degree deviated from the coordinated development trajectory from 2018 to 2020. The classification of the static coordination degree of various regions in the YREB gradually becomes obvious with significant spatial aggregation characteristics, and the dynamic coordination degree of various regions has significant heterogeneity. (3) The opening-up degree, foreign direct investment, population growth, and urban–rural income gap are not advantageous to the coordination degree, while the marketization level, industrial structure, and human capital are advantageous to the coordination degree, but the regression coefficients of the latter two are not significant. The regional regression results show that the impacts of driving factors on the coordination degree have obvious heterogeneity. The research results provide a new idea and method that can be used by developing countries similar to the YERB to control water pollution, improve the ecological environment, alleviate water shortages, and improve the level of WEC in the process of NU.

The relationship and obstacles between sustainable development (SD) and ecosystem services (ESs) are crucial factors for SD decision-making and ecological conservation strategies. The production-living-ecological (PLE) functional perspective provides a new research entry point to analyze the interrelationship between the SD of human society and ESs. In view of this, based on the Sustainable Development Goals (SDGs), this study established an SD localization evaluation framework from the perspective of the PLE functions and subsequently evaluated the SD levels of 16 cities in Yunnan Province from 2005 to 2020. Furthermore, changes in the ecosystem service value (ESV) were explored by combining the PLE land classification and dynamic equivalence methods. The relationship between SD and ESV was then analyzed using the modified coupling coordination degree (CCD) model. Finally, the obstacle degree model was introduced to identify the main factors affecting the CCD level of the two systems. The results revealed the SD level in Yunnan Province to be high in the central region and low in other areas. From 2005 to 2020, the province’s SD level increased from 0.146 to 0.341. Furthermore, the main contribution of ESV originated from ecological land (over 90%). The ESV was higher in the southwest of Yunnan Province compared to that in the northeast. From 2005 to 2020, the ESV decreased by 2.231 billion CNY and was dominated by the regulation services. The CCD level increased significantly from 2005 to 2020. The CCD subcategory changed from SD lag to ESV lag and ESV-SD balanced type. Moreover, the dominant obstacle factors did not change significantly during the study period. The ESV and SD systems were dominated by regulation services and sustainable production subsystems, respectively. The research results have important guiding significance for further optimization of regional development strategies and ecological protection measures.

“…The escalating severity of environmental pollution, resulting from population growth, rapid economic development, and ecological destruction, has rendered the protection of the environment against pollution an exceedingly critical issue. − Harmful pollutants encompass a diverse range of organic molecules. For example, explosives include trinitrotoluene (TNT), 4-nitrophenol (4-NP), and 2,4,6-trinitrophenol (TNP) etc. − Due to its higher explosive potency compared with TNT, TNP was extensively utilized during World War I 2 and gained recognition for its widespread application in antiseptic treatments for burns, malaria, and smallpox, as well as in chemistry laboratories …”

Novel Covalent Bonds and Hydrogen Bonds Linked Porous Organic Frameworks as Chemosensor for Detecting 2,4,6-Trinitrophenol in Water and Soil Samples

A novel and unconventional structural porous organic framework combined through the synergistic effect of covalent bonds and hydrogen bonds was prepared with the combination of 4,4′,4″,4‴-(pyrene-1,3,6,8-tetrayl)tetraaniline (Py) and 5-hydroxyisophthalaldehyde (HP). It was the second example of CHOF until now and had been designated as Py−HP CHOF. The suspension of Py−HP CHOF in various solvents, such as ethanol, CH 3 CN, and methanol, exhibited a remarkably selective and sensitive "on−off" fluorescence response toward 2,4,6trinitrophenol (TNP) compared with other explosives, with exceptionally low detection limits. The X-ray diffraction (XRD) spectra confirmed that the framework of Py−HP CHOF collapsed after interaction with TNP and acid, further indicating the existence of hydrogen bonds in the framework of Py−HP CHOF. The fluorescence quenching can be ascribed to the photoinduced electron transfer and the absorption competition quenching, as supported by XRD, X-ray photoelectron spectroscopy results, UV−vis absorption spectra, and density functional theory calculations. Fluorescence channels can be utilized by Py−HP CHOF to function as chemosensor, enabling the identification and detection of TNP in water and soil, and Py−HP CHOF is also the second CHOF example of sensing TNP reported to date. The application of this technique exhibits considerable potential in the analysis and detection of environmental pollutants, thereby presenting substantial practical implications.
