这种相互作用在一定程度上控制BCNPs和IMNPs之间异质聚集,并且在不利于纳米颗粒稳定的条件下(酸性pH、HA和IS)更为明显。因此,BCNPs-FHNPs异质聚集的增强作用大于BCNPs-MTNPs。而在BCNPs-GTNPs系统中,虽然BCNPs-GTNPs相互作用能大小居中,GTNPs的高浓度和棒状结构促进异质聚集和沉降。我们的结果阐明了pH、IS、H...
chemicaloxidationrely on various climatic conditions such asfeedstocktype, pyrolysis temperature, soil pH, biochar pH, soil CEC andsoil texture.29,30Biochar prepared at low temperature posses less C:N ratio and has been observed to be mineralized early and help ameliorate soil microbial structure. ...
It is also observed that the volatile matter content decreases from 21.3% to 6.7% when the pyrolysis temperature increases from 300 °C to 600 °C (Table1) as the thermal degradation of biochar is gradually complete with the increase of pyrolysis temperature. In addition, ash content in ...
Drastic changes in biochar structure occurred throughout the reaction, especially for low degrees of conversion. The BET surface area of the biochar increased significantly until the conversion reached 0.49, and there was a steep decrease at high degrees of conversion. The biochar showed a high ...
4e). Organic fertilizers improved SOC and soil structure (Fig. 2g), and enhanced the performance of microorganisms related to soil aggregate structure, thus promoting the production of aggregates and reducing the amount of NH4+ converted to NO3− (Luan et al. 2019). However, the alteration ...
At the molecular scale, the main component of nanobiochar carbon was mainly the aromatic structure (Ma et al. 2019). At higher pyrolysis temperatures (800–900 °C), smaller aromatic rings form larger and more stable aromatic ring structures that were more difficult to depolymerize (Feng et ...
At the same time, the interconnected pore structure of well-structured biochar facilitates efficient diffusion and transfer of adsorbate molecules through its pores, thereby augmenting adsorption performance29. This information can help researchers, agricultural scientists, and biochar producers optimize ...
Biochar, a solid material with high carbon (C) content, is produced during high-temperature pyrolysis of biomass such as crop straw, wood, manure, and solid waste (Schmidt and Noack2000; Lehmann2007). It has a very porous structure with a large specific surface area covered with active funct...
structure, whereas alginate–phenol bonds are the primary linkage governing the rigidity of seaweed cell walls (Deniaud-Bouet et al.2014; Tiwari and Troy2015). The association between protein in brown seaweed and phenols and sulphated fucans was observed (Deniaud-Bouet et al.2014)....
