Biomass from agro-industrial waste is a vital renewable resource for addressing energy and environmental challenges. Hydrothermal carbonization (HTC) is utilized to produce hydrochar from various materials, including the...

Abstract Zinc oxide (ZnO) nanoparticles are widely explored for photocatalytic degradation of organic pollutants due to their high stability, low cost, and environmental compatibility. In this study, ZnO nanoparticles we...

Abstract Long-root Eichhornia crassipes, an aquatic plant with extensive root systems, has demonstrated potential in remediating eutrophicated water bodies. However, improper disposal of large quantities of discarded pla...

Abstract Within the KONATES project, a pilot system was set up in the Science Park in Leipzig to investigate the feasibility of combining Aquifer Thermal Energy Storage (ATES) with groundwater remediation. Along with the...

Abstract Antibiotic residues in aquatic systems accelerate antimicrobial resistance and require efficient solar-driven advanced oxidation strategies. Herein, we engineer an oxygen-vacancy-rich La-doped NiFe₂O₄ spinel...

Water pollution by coexisting multiple contaminants presents escalating challenges to environmental remediation and public health protection. In advanced oxidation processes, contaminant interactions are invariably regar...

In recent decades, alternative propulsion systems have been investigated and have attracted great interest in the space community. Most of these alternative propulsion systems need propellants. One alternative propulsion...

Mathematics readiness at entry remains critical for success in first-year engineering programs, yet many institutions lack transparent, reusable tools to diagnose risk and design levelling policies. This study develops a...

Mathematics in the Modern World (MMW) is a core general education course that develops quantitative reasoning and applied problem solving, yet many first-year students struggle with its concepts and applications. Such ch...

Abstract Microorganisms play key roles in nutrient cycling and soil remediation in saline-alkaline ecosystems. However, how their assembly rules and interaction networks change during natural succession remains unclear. ...

The co-production of bio-char and upgraded bio-oil by fast pyrolysis of raw and sulfuric-acid pretreated agro-industrial wastes (corn cob, sugarcane bagasse and sunfower seed hull) was investigated to valorize wastes as ...

The mechanistic understanding of toxic metals reactive transport in complex porous media is essential for pollution prediction and remediation in soil-groundwater systems. This study aims to experimentally and numericall...

Abstract Rising atmospheric carbon dioxide is projected to exceed 800 ppm by 2100, yet its impact on acid mine drainage (AMD), which is currently contaminating 480,000 km of rivers, remains unclear. Here we combine a g...

The Batanghari River is increasingly contaminated by organic and inorganic pollutants resulting from intensive human activities, posing significant risks to both ecosystems and public health. This study evaluates the pot...

The study explores an eco-efficient synthesis method for hydroxyapatite (HAP) from mineral residues rich in calcium carbonate (CaCO3) and monopotassium phosphate (KH2PO4). The process is based on a chemical reaction in a...

Bismuthoxide-based catalysts gained attention for photocatalytic remediation of environmental pollutants owing to their low cost, feasibility, stability, small, and tunable band gap. In the present work, bismuth molybdat...

Zeolite-based catalysts, owing to their adjustable acidity, high thermal stability, and well-defined microporous frameworks, play a crucial role in thermocatalytic processes such as hydrocarbon conversion and environment...

"The water pollution due to emerging organic pollutants, such as agrochemicals, has become a topic of growing interest worldwide. The increase of pollutants in aquatic systems stimulated the development of new strategies...

En las últimas décadas y con la finalidad de disminuir el problema de la contaminación acuática, sobre todo aquella causada por la presencia de metales pesados, se han buscado técnicas fisicoquímicas y biológicas ...
