Nineteen percent of the global population may face a high probability subsidence
In this work, a novel heterojunction catalyst was constructed by introducing Ti3C2 MXene quantum dots (QDs) into SiC. The QDs/SiC composite showed 74.6% efficiency in NO pollutant removal under visible light irradiation, which is 3.1 and 3.7 times higher than those of the bare SiC, respectively. existing SiC can function as channel for electron hole transfer. enhanced absorption, increased superoxide radical, strong oxidization ability endow with superior photocatalytic performance NOx...
A new microporous MIL-100(Fe)/Ti3C2 MXene composite was constructed as a non-noble metal-based Schottky junction photocatalyst with improved nitrogen fixation ability. Ti3C2 nanosheets exhibited excellent metal conductivity and were employed two-dimensional support to optimize the composite's energy band structure. MIL-100(Fe) large specific surface area used an adsorbent photocatalytic oxidation center. The not only higher thermal stability but also showed significantly increased activity...
In this work, we investigate the temporal evolution of ground deformation affecting ocean-reclaimed lands Shanghai (China) megacity, from 2007 to 2016, by applying Differential Synthetic Aperture Radar Interferometry (DInSAR) technique known as Small BAseline Subset (SBAS) algorithm. For analysis, exploited two sets non-time-overlapped synthetic aperture radar (SAR) data, acquired 2010, ASAR/ENVISAT (C-band) instrument, and 2014 2016 X-band COSMO-SkyMed (CSK) sensors. The long time gap (of...
Many coastal cities have undertaken reclamation projects to satisfy the land demands of rapid urbanization. However, foundations reclaimed are susceptible settlement and can undesirable environmental impacts that could adversely affect these dense, populated areas. In case international airports built on areas especially, regional-scale deformation must be monitored ensure operational security for public safety. Persistent Scatterer SAR Interferometry (PSI) technology has proven an effective...
This paper is aimed at studying the temporal evolution of surface displacements occurred over past few years in ocean-reclaimed platforms Shanghai megacity (China), which are mainly ascribable to consolidation processes large dredger fills and alluvial deposits. With respect previous analyses carried out same area, this work provides a joint multi-platform differential interferometry synthetic aperture radar (DInSAR) analysis, based on application advanced Small BAseline Subset (SBAS)...
Land subsidence resulting from over-exploited groundwater has become a leading factor restricting the sustainable development of resources, environment, and economy in Shanghai. To design management plans to control environment geology calamity problems arisen by land effectively, this research constructed risk index system on basis source identification then established assessment model. The is composed hazardous conditions vulnerability subsidence. Results comprehensive consideration model...
In this study, finite‐time passivity of switched non‐linear systems is developed. First, a concept proposed using multiple storage functions. Second, switching law designed to make system passive. Third, on the basis concept, properties are investigated. On one hand, can induce stability. other preserved under feedback interconnection and parallel interconnection. Furthermore, merging signal technique employed an interconnected Finally, example provided demonstrate effectiveness obtained results.
Focusing on the Yangtze River economic zone, previous geological researches are systematically summarized, resources and environment conditions major problems which needing to be concerned in land planning construction studied. The results show that resource of cultivated land, shale gas, geotherm, lithium so superior conducive develop modern agriculture, clean energy industry strategic emerging industries. 3×10<sup>13</sup> m<sup>2</sup> farmlands without heavy metal pollution concentrated;...
In this work, a new composite photocatalyst was synthesized by flower-like Bi2O3 and two-dimensional multilayer V2C using facile hydrothermal method. Compared with the pristine sample, specific surface area of Bi2O3/V2C MXene is significantly increased, which favourable to improve photocatalytic efficiency. The analysis UV-vis absorption spectrum band gap energy shows that construction heterojunction broadens light response range, improves capacity, obtains narrower than any single...
Abstract Urban cover-collapse sinkholes pose a significant global challenge due to their destructive impacts. Previous studies have identified groundwater fluctuations, subsurface soil conditions, pipeline leakage, precipitation, and subterranean construction activities as key contributors these phenomena. However, unique geological settings across different urban environments lead variations in the primary factors influencing sinkhole formation. This study focuses on Shanghai, city notable...
Major function-oriented zoning, a key spatial planning strategy in China, aims to coordinate resource endowments, socio-economic development, and subsequent initiatives. However, the existing framework for major zoning relies predominantly on statistical indicators at regional level, often neglecting critical role of carrying capacity. To address this limitation, we assessed both current state dynamic trends capacity identify risk advantageous zones functions, with objective optimizing...
