Abstract:
... Biochar aging affects the stability of soil carbon. Analyzing the effect of biochar on soil organic carbon (SOC) forms and their relations with microbial community assembly and carbon metabolism with time is helpful for soil carbon sequestration (by adapting the farm management approach). Four treatments with no, low, medium, and high biochar application rates (0 %, 1 %, 2 %, and 4 % of the total ...

Abstract:
... The rather high energy penalty of CO₂ capture is the critical gap deterring the deployment of Carbon capture and storage technologies. A deeper understanding of the mechanism of CO₂ capture will lay a foundation for reducing energy consumption. Accordingly, this paper introduced a thermodynamic analysis method with a new criterion to reveal the mechanism of energy consumption in a power system int ...

Rivers play a critical role in the global carbon cycle, but the processes can be affected by widespread microplastic (MP) pollution and the increasing frequency of heat waves (HWs) in a warming climate. However, little is known about the role of river microbes in regulating the carbon cycle under the combined action of MP pollution and HWs. Here, through seven-day MP exposure and three cycles of H ...
