Comparison of the Photodegradation of Pharmaceuticals and Personal Care Products (PPCPs) in Water and Ice

Abstract Photochemical reactions are prevalent in natural aquatic environments and play a crucial role in aquatic ecosystems. Sunlight-induced photodegradation is particularly effective in degrading various pharmaceuticals and personal care products (PPCPs). However, the photoche...

Explainable Machine Learning Combined with Feature Selection and Bayesian Optimization for Predicting Rare Earth Elements and Yttrium in Coal: A Case Study of China’s Five Major Coal-Bearing Regions

Abstract Determining the concentrations of rare earth elements and yttrium (REY) in coal is essential for evaluating coal-hosted critical metal resources and understanding their geochemical controls. However, conventional laboratory analyses are costly, time-consuming, and spatia...

TiO2/Saponite composite catalyst for ultraviolet photocatalytic ozonation of coal chemical wastewater

In ultraviolet photocatalytic ozonation (UV-PCO 3 ) systems, the limited ozone adsorption capability of conventional catalysts restricts the synergistic coupling between catalytic ozonation and photocatalysis. In this study, a TiO 2 /saponite (TiO 2 /Sap) composite catalyst was s...

Divergent behavior of leachate pollutants in China: Insights from a national database and long-term monitoring

Despite the significant spatial heterogeneity of leachate quality across municipal solid waste (MSW) landfills in China, the underlying mechanisms and potential divergent behavior among different pollutants remain poorly understood. To address this gap, a national leachate qualit...

Progress And Challenges in Supercritical CO2 Corrosion and Protection: A Review

Abstract Internal corrosion during dense-phase CO2 and SC–CO2 transport and injection is jointly governed by interfacial aqueous phases, impurity reactions, and the evolution of the corrosion product films. This review systematically examines phase behavior, water content, impuri...

Promoting Effects of CuSO4 Modification on N2 Selectivity of 1Ru/5Ce-TiO2 Catalyst for Selective Catalytic Oxidation of NH3

Abstract xCu+1Ru/5Ce-TiO2 catalysts were prepared by a grinding method to improve the NH3–SCO performance of 1Ru/5Ce-TiO2. The results revealed a marked promotion of N2 selectivity over 1Ru/5Ce-TiO2 upon CuSO4 incorporation. In particular, the 5Cu+1Ru/5Ce-TiO2 catalyst exhibited...

Mechanisms of operational parameters influencing aeration performance in inverted umbrella aerators: an experimental study supported by CFD analysis

ABSTRACT The graphical abstract presents a comprehensive overview of the inverted umbrella aerator study. The top left illustrates a schematic of the aerator in a 5m multiplication sign 4m multiplication sign 1.2m tank, with its variable immersion depth spanning -60 to +80mm. Adj...

Performance and Resilience of Oxidation Ditch and Step-Feeding Anoxic–Oxic Processes during Extreme Rainfall Events: Evaluation and Optimization Strategies for Wastewater Treatment Plants

Abstract Extreme rainfall poses significant challenges to the operational stability of wastewater treatment plants (WWTPs). This study used full-scale plant data to evaluate the robustness and nutrient removal performance of oxidation ditch (OD) and step-feeding anoxic–oxic (AO)...

A Bacterial–Microalgal–Manure Co-Application Ameliorates Saline-Alkali Soil and Promotes Wheat Growth

Severely saline–alkaline land degradation poses a considerable challenge to sustainable agriculture, owing to high salinity, elevated pH, and nutrient deficiency. To address this, a salt-tolerant nitrogen-fixing bacterium (Bacillus sp.) and a microalga (Chlorella pyrenoidosa) wer...

Waterborne polyurethane modified CFBFA cementitious materials properties and mechanism

This study addresses the challenge of directly and efficiently utilising circulating fluidised bed fly ash (CFBFA), which is difficult to employ due to its high calcium, high sulfur, and low reactivity, by introducing environmentally friendly waterborne polyurethane (WPU) as a mo...

Advancing Energy Efficiency in Smart Windows via Dual‐Responsive Electro‐Thermochromism

ABSTRACT Implementing dynamic smart windows is imperative toward the construction of net‐zero buildings. However, the prevailing ion (de‐)embedding‐based electrochromic (EC) or thermosensitive hydrogel‐based thermochromic (TC) windows fail to achieve large optical modulation acro...
