Abstract: Methods and systems are disclosed to determine a permeability value and a permeability image of a rock. The process can include determining labeling of a 3D segment of a rock. The labeled segments can be determined using, for example, computer vision and machine learning and can be used to determine a grain size of a 3D rock segments. The grain size value can be used to determine a permeability value for the 3D rock segment. The permeability value of the 3D rock segment can be used to determine the heterogeneous permeability of the rock.

Abstract: A method of printing a hydrogel-based device includes contacting a monomer, a crosslinker, a photoinitiator, and a precursor salt with a solvent to form an ink solution, printing the ink solution onto a substrate, exposing the ink solution to light, sufficient to form a hydrogel, and contacting the hydrogel with a reducing agent sufficient to precipitate nanoparticles from the precursor salt in the hydrogel.
