Montmorillonite facilitated Pb(II) biomineralization by Chlorella sorokiniana FK in soil

Jiaqi Tan et al.

Summary: This study found that adding montmorillonite in soil can facilitate Chlorella sorokiniana FK's biomineralization of lead, increasing the algae's tolerance to lead poisoning. The montmorillonite promotes photosynthesis and urea hydrolysis in Chlorella, enhancing the biomineralization process of lead.

Bio-mediated soil improvement: An introspection into processes, materials, characterization and applications

Ning-Jun Jiang et al.

Summary: Soil is not just made up of inorganic phases, as microorganisms such as bacteria, archaea, and eukaryotes have the ability to alter the properties of soil in geotechnical engineering practices. Among these, microbial-induced calcium carbonate precipitation (MICP) has gained significant attention for improving soil engineering performance. Recent developments in bio-mediated geotechnics focus on popular and alternative MICP processes, innovative raw materials and additives, testing methodologies for characterizing MICP at multi-scale, and applications in emerging and unconventional geotechnical fields.

Influences of water and salt contents on the thermal conductivity of loess

Xusheng Yan et al.

Summary: This study used the transient plane heat source method to measure thermal conductivity and explored the effects of water and salt content on heat transfer within soil. The formation of liquid bridges and the heat transfer behavior of NaCl brine were observed, with the model by Usowicz et al. found to best describe soil thermal conductivity with salt contents ranging from 0% to 6%. The research provides valuable insights for geothermal resource development in the Guanzhong area and engineering projects in loess regions.

Revealing the Enhancement and Degradation Mechanisms Affecting the Performance of Carbonate Precipitation in EICP Process

Wenle Hu et al.

Summary: This study compares the ordinary EICP process with the modified EICP process, finding that the modified EICP process subjected to higher MgCl2 concentrations performs the best, with the mechanism of carbonate precipitation enhancement interpreted through elevating urease enzyme activity by introducing magnesium ions. Different degradation phenomena of carbonate precipitation occur when subjected to higher NH4Cl and CaCl2 concentrations, highlighting the potential use of EICP technology for the protection of heritage buildings in NW China.

Effects of water content and salt content on electrical resistivity of loess

Zhao Duan et al.

Summary: The electrical resistivity of loess is significantly influenced by water content and salt content, exhibiting an exponential relationship with water content and reaching its maximum conductivity when NaCl content reaches a certain level. The relationship between loess electrical resistivity and test frequency is nonlinear, with an increase in frequency leading to a decrease in resistivity. The three paths model and double-layer structure can explain the phenomena observed in the study.

Summary: The study found that temperature and Darcy velocity have negligible effects on the individual transport of heavy metals, with a higher recovery ratio for Cd2+ over Pb2+. The presence of SiO2 suspended particles can enhance the transport of heavy metals due to strong adsorption, but this effect decreases with the size of the SiO2 particles.
