In this section, some fundamental concepts of the NMM are firstly recalled. Porous Materials Mistaken for Nonporous Materials. The most common semi porous material is brass. Mold has no way of growing below the surface of non-porous materials. As an alternative, recent studies have found that MOFs can serve as precursors for porous semiconductor materials, including porous metal oxides, carbon materials, and metal sulfides, and their heterostructures, through the facile thermal treatment or sulfidation process [54,55,56,57,58,59,60]. Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.
