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.

Aspects of the disclosure include a multilayer surface-covering assembly adapted to convert solar radiation to heat. The multilayer surface-covering assembly may include a first composite layer comprising a first amorphous refractory material and first metal nanoparticles, wherein the first amorphous refractor material encapsulates the first metal nanoparticles, and wherein the first composite layer is thermally coupled with a surface of a structure for conduction of heat from the first composite layer to the structure. The multilayer surface-covering assembly may also include an antireflective layer, wherein the first composite layer is disposed between the antireflective layer and the surface of the structure.

Methods of preparing a mineral-coated rock micromodel can include 3D-printing a transparent porous micromodel with photo-curable polymer, seeding a thin layer of mineral nanoparticles in the network of pores inside the micromodel, and subsequently growing a mineral layer on the thin layer of mineral nanoparticles. The thin layer of mineral nanoparticles can be introduced by injecting a suspension containing the mineral nanoparticles through the microporous polymer micromodel, and the mineral layer can be grown in-situ on the thin layer of mineral nanoparticles in the network of pores by injecting an ion-rich solution configured to crystallize from solution in response to contacting the mineral nanoparticles.

Three-dimensional printing on a membrane of a filtration device is described herein. Forming the filtration device involves receiving a membrane comprising a porous material, depositing an ink into pores of the porous material, causing the ink to solidify, and continuously building three-dimensional printed structures via micro-stereolithographic three-dimensional printing. Solidifying the ink causes the ink to bond with the membrane.
