Comprehension of NP transport and\ninterac tions with hydrophobic surfaces and interfaces -given their\nubiquity in p orous aquifers- is essential for groundwater remediation\nfrom organic con taminants\, toxic engineered NPs\, and nanoplastics.\n\nThis research inve stigates the transport and attachment of hydrophobic\nNPs under varying ph ysicochemical conditions in saturated and\nunsaturated porous media by int egrating experimental observations\nacross multiple scales\, theoretical e xtended-DLVO predictions\, and\nnumerical modeling. A non-toxic\, negative ly-charged\, hydrophobic model\nNP system synthesized from ethyl cellulose (EC)\, and exhaustively\ncharacterized for colloidal stability and interf acial interactions\,\nwas employed to systematically explore NP interactio ns with\nfluid-fluid and solid-fluid interfaces.\n\nThe upscaling capabili ty of an advection-dispersion-retention\ncontinuum model was compared vis- à-vis a pore network model of\nirreversible NP attachment onto fluid inte rfaces in 3D columns packed\nwith spherical glass beads\, showing that the latter captures key\npore-scale dynamics such as bypassed interfaces\, sl ow-moving corner\nflows\, and diffusion-dominated retention.\n\nTransport experiments in 2D microfluidic pore networks confirm that\nthe dynamics of NP retention in unsaturated porous media depend not\nonly on the saturati on of the non-wetting phase\, but also on its\nconnectivity and the access ibility of immobile fluid-fluid interfaces.

Scaling from lab t o\nindustry is limited by gradients from poor mixing\, reducing yields\nth rough cell stress and adaptation. This work quantified dissolved\noxygen\, pH\, and kLa gradients in a 20 L bioreactor. While cell density\nand meta bolite gradients were inconclusive\, metabolic responses were\nmodeled wit h modified Monod kinetics\, which adapted well to differing\nconditions.

The results\nof this work demonstrate that REVs can be identified from relati vely\nsmall fractions of the total image volume given that certain\ncondit ions are met\, offering a balance between accuracy and\ncomputational effi ciency.
