An example method includes receiving saline water at a desalination tank, the desalination tank including a porous substrate impregnated with metal particles in a fixed position within the desalination tank, contacting the saline water with the porous substrate to remove impurities from the water, thereby forming treated water, and outputting the treated water.

A method for producing adsorption materials coated with polytetrafluoroethylene (PTFE) includes providing a suspension of PTFE in water (1 to 20 wt % PTFE based on the suspension weight), providing zeolite, mixing the PTFE suspension with the zeolite to form a dispersion, and drying the dispersion to obtain a PTFE-coated adsorption material. The present disclosure also relates to a PTFE-coated adsorption material, its use for adsorbing carbon dioxide from gas mixtures, and a method for extracting carbon dioxide using the PTFE-coated adsorption material. The PTFE coating enhances CO.sub.2:H.sub.2O selectivity, reducing water adsorption while maintaining CO.sub.2 adsorption capacity, enabling efficient carbon dioxide capture, particularly in direct air capture applications.

The present disclosure is directed to stationary phase materials for performing size exclusion chromatography. Embodiments of the present disclosure feature hydroxy-terminated polyethylene glycol surface modified silica particle stationary phase materials, which are optionally also methoxy-terminated polyethylene glycol surface modified.

The present disclosure is directed to surface modified materials such as stationary phase materials for performing size exclusion chromatography. Aspects of the present disclosure feature materials surface modified with a moiety including a polyethylene glycol (PEG) functionality and a moiety comprising a diol functionality. Such surface modified materials exhibit a reduced propensity for ionic and hydrophobic secondary interactions.
