Achieving the dual goals of improving water quality and reducing carbon emissions requires a systematic study of the combined effects of economic and environmental policies on industrial systems. A CGE-IWCR model is developed to examine the long-term evolution of industrial economic and environmental responses in the Yangtze River Economic Belt (YREB) under varying levels of carbon and water pollution taxes. The CGE-IWCE model offers several advantages: i) under the dual tax (carbon and water pollution tax) interventions, it can effectively forecast industrial CO2 and water pollution emissions driven by both macro and local factors from 2025 to 2060;ii) it quantitatively captures the interactions between various policy interventions, thereby providing guidance for comprehensive regional policy formulation. It is discovered that in the double-tax scenario, various combinations of carbon and water pollution taxes significantly impact direct carbon emissions and direct water pollution emissions, and from local consumption, imports, and exports in industrial sectors. Among them, the dual pressure of high carbon and water pollution taxes, which significantly raise production costs. In addition, increasing the carbon tax from 10 ¥/tonne to 50 ¥/tonne, the water pollution equivalent (WPE) reduction rate rises from 20.79% to 52.67% with the increase in the carbon tax from 2050 to 2060, when the water pollution tax is low. Between 2025 and 2060, the carbon tax plays a significant role in influencing the total industrial output change rate in YREB. from 2025 to 2060, the water pollution tax will play a more significant role in CO2 reduction in YREB’s industrial sector. The results will offer decision-making support for water pollution reduction and carbon mitigation in the YREB’s industrial sector, quantitatively identify the interactions between the dual taxes, and provide new insights for analyzing the impacts of pollution reduction and carbon mitigation policies.

This study investigates the effectiveness of the Cu-doped Bi2O3 method for removing antibiotics. Cu at varying concentrations of 0%, 2%, 4%, 6%, and 8% was used to synthesize Bi2O3 material successfully. The optimal results were obtained by adding 4% Cu to the Bi2O3 matrix. Cu-doped Bi2O3 was characterized by an energy band gap of 2.32 eV, a crystal size of 37.04 nm, and α-Bi2O3 and Rouaite phases. Material containing Cu-doped Bi2O3 was used to degrade antibiotics such as amoxicillin (AMX), ciprofloxacin (CIP), and tetracycline (TC). The various removal techniques investigated include adsorption, photolysis, and photocatalysis. The photocatalytic procedure yielded the highest results in terms of degradation efficiency. The removal efficiency of each antibiotic using the photocatalytic method varies, with AMX at 52.06%, CIP at 61.72%, and TC at 69.44%. Cu-doped Bi2O3 degraded TC-type antibiotics more rapidly, with a reaction rate constant of 0.0065 minutes-1, according to the results of the reaction rate constants. The high removal efficiency and rapid reaction rate indicate that Cu-doped Bi2O3 is an effective antibiotic removal agent, especially for tetracycline-type antibiotics. © 2023, The Authors.

Integrated photodetectors are crucial for their high speed, sensitivity, and efficient power consumption. In these devices, photocurrent generation is primarily attributed to the photovoltaic (PV) effect, driven by electron-hole separations, and the photothermoelectric (PTE) effect, which results from temperature gradients via the Seebeck effect. As devices shrink, the overlap of these mechanisms—both dependent on the Fermi level and band structure—complicates their separate evaluation at the nanoscale. This study introduces a novel 3D photocurrent nano-imaging technique specifically designed to distinctly map these mechanisms in a Schottky barrier photodiode featuring a molybdenum disulfide and gold (MoS2-Au) interface. We uncover a significant PTE-dominated region extending several hundred nanometers from the electrode edge, a characteristic facilitated by the weak electrostatic forces typical in 2D materials. Unexpectedly, we find that incorporating hexagonal boron nitride (h-BN), known for its high thermal conductivity, markedly enhances the PTE response. This counterintuitive enhancement stems from an optimal overlap between thermal and Seebeck profiles, presenting a new pathway to boost device performance. Our findings highlight the capability of this imaging technique to not only advance optoelectronic applications but also to deepen our understanding of light-matter interactions within low-dimensional systems. © 2024, CC BY.

Journal of Geoscience and Environment Protection 2021年第4期9卷 147-165页

The chemical and physical properties of soil are critical factors that affect human health. The current geochemical study is designed to evaluate the concentrations of heavy metals (Cr, Pb, and Zn) in the soil in Iowa (IA), Kansas (KS), and Nebraska (NE). The basic descriptive statistical results suggest that there are some limited levels of the heavy metals in the soils that come from anthropogenic inputs. The results of three environmental metrics, the enrichment factor (EF), geoaccumulation (Igeo), and potential ecological risk (PERI), have been calculated, evaluated, and compared. EF values show that soils contain minimal enrichment of Cr, Pb, and Zn in the study area. In addition, PERI values presented low risk with Cr, Pb, and Zn. However, Igeo values showed no contamination of Cr, Pb, and Zn in the study area. These results suggest that the elevated levels of these heavy metals are dominated by the historic agricultural inputs derived from long-term anthropogenic applications, especially in the regions with extensive human activities, which means that soil is the sink for heavy metals released into the environment.

Mangrove ecosystem in Pekalongan city provides significant ecological functions, biodiversity hot spots, economic and social benefits, ecosystem services, coastal protection, and sources of livelihood for local people in Central Java. Currently, this mangrove ecosystem is undergoing significant degradation, primarily due to anthropogenic activities such as waste from the batik industry, textile production, and residential areas., Mangroves, which are a fence between land and sea, are very likely to be exposed to microplastic waste. Waters and sediment samples were analyzed to find the microplastics at mangrove area. The analyzed of shape, size and colors using Microscope Motic SMZ-161 equipped with camera and the functional group of the polymers were analyzed using ATR-FTIR. From this research the microplastics abundance were 109 particles/l from total of all research stations in the water column and 153 particles/kg from total of all research stations in the sediment. The functional group polymer identified the polyamide, polystyrene, rayon, polyethylene terephthalate, polyethylene, and polyester at this research area. The anthropogenic activities in this area will increase waste in the form of microplastics and other chemicals, which will end up in marine waters and can have an impact on the mangrove growth and health. © 2025, The Authors.

The effects of hematite and brucite additions on fresh- and hardened-state properties of metakaolin-based geopolymer were investigated. Metakaolin-based geopolymer was produced with three Si/Al molar ratios and supplemented with hematite or brucite using three Fe/Al and Mg/Al molar ratios. Rheology, setting time, permeable porosity, compressive strength, and resistance to sulfuric acid of metakaolin-based geopolymer were measured. Experimental results show that, at Si/Al = 1.75 and 2.0, the hematite addition reduced the setting time whereas the brucite addition prolonged setting times, indicating an accelerated and delayed alkali-activation process of metakaolin-based geopolymers, respectively. At Si/Al = 1.5, both additions accelerated the setting time but increased the permeable porosity. Both additions reduced the bulk mechanical properties but improved sulfuric acid resistance. Pastes with brucite exhibited better sulfuric acid resistance than the counterpart with hematite. The paste immediately surrounding the agglomerates of hematite and brucite particles exhibited lower and higher micromechanical properties, respectively. © 2024, The Authors. All rights reserved.

The past COVID-19 pandemic has led to a surge in the use of disposable masks, posing a significant environmental challenge due to the swift accumulation of waste. This study explores the potential of pyrolysis to transform this waste into valuable pyrolysis oil with characteristics akin to gasoline, addressing both waste management and energy derivation concerns. Pyrolysis, a thermal decomposition process, was applied to mask materials, producing an oil with a high calorific value of 45.93 MJ/kg. The chemical makeup of this pyrolytic oil was meticulously characterized using Pyrolysis-Gas Chromatography-Mass Spectrometry (PY-GC/MS) and Fourier-transform Infrared Spectroscopy (FTIR), confirming the presence of hydrocarbons similar to those found in gasoline. Achieving an efficiency of 41.865 %, the pyrolytic approach demonstrated a promising potential for not only managing mask waste but also creating an alternative energy carrier. However, the study advises that before considering this pyrolytic oil for engine use, a thorough evaluation of its combustion quality, engine compatibility, and environmental impact is essential. This investigation advances the discussion on sustainable waste management, offering insights into the generation of alternative fuels from daily waste streams, while also highlighting the necessity for comprehensive analyses to ensure the practicality and efficiency of such novel energy solutions. © 2023 The Author(s)
