The crucial role of protein corona in mediating the colloid stability and co-transport behaviors in saturated quartz columns.

Clarifying the stability and co-transport of environmental colloids and radionuclides in porous media is crucial, as they pose potential risks to nuclear environmental safety. However, there is limited knowledge of the significant role of protein corona in Eu(III) transport carried by bentonite colloids (BC) in the presence of bovine serum albumin (BSA). The protein corona mediated the stability and co-transport behaviors of BC and Eu(III) in saturated quartz columns were investigated, and a ripening adsorption co-transport model (RACM) was established to qualitatively describe the Eu(III) transport by composited colloids.

Predicting anion diffusion in bentonite using hybrid machine learning model and correlation of physical quantities.

Radionuclide diffusion will be influenced by numerous factors. Establishing a model that can elucidate the internal correlation between mesoscopic diffusion and the microscopic structure of bentonite can enhance the comprehension of radionuclide diffusion mechanisms. In this study, a light gradient boosting machine (LightGBM) was employed to predict the effective diffusion coefficients of HCrO, I, and CoEDTA in bentonite.
