Biosensors play a very important role in pollutant monitoring, but there are still some problems such as stability, repeatability and low detection limits. Therefore, it is necessary to explore ways to increase the performance of biosensors. In this study, biochar-MFC sensors were constructed for heavy metals monitoring in constructed wetlands (CWs), and the correlation, repeatability […]

Hydrothermal carbonization (HTC) is a promising and powerful technology for manufacturing magnetic biochar with abundant functional groups at relatively low temperature. Herein, K2FeO4-accelerated HTC of kelp was studied to manufacture high-performance magnetic biochar for eliminating tetracycline (TC) in aqueous solution. Nanoscale magnetic iron oxides were generated with abundant oxygen containing groups and porous structures as […]

Biochar addition is recognized as a promising way to increase the potential of anaerobic digestion. However, few studies have investigated the interaction between biochar leaching in complex, practical anaerobic digestion systems and the negative effects that biochar leachate may have on the anaerobic digestion process. The traditional measurement methods are relatively simple, but may underestimate […]

Abstract The continuous development of the economy and the constant improvement of living standards have stimulated the development of animal husbandry. This development has been accompanied by the massive production of animal manure with various bad odors and high heavy metal content, constituting severe damage to ecological security and human health. Traditional disposal methods, including composting and anaerobic […]

Abstract Decarbonisation will see mass installation of wind turbines and solar panels to replace conventional energy systems. However, these renewables face two challenges: renewable energy production is intermittent, and land requirements are considerable. We propose a solution to both problems: production of green ammonia, a carbon-free fuel, in the ocean. Green ammonia can be produced […]
