membranie

Membranie is a term used in Polish-language scientific writing to denote membranes, thin semi-permeable barriers that separate two compartments and regulate material exchange.

In biology: Biological membranes—plasma membranes and organelle membranes—are mainly composed of a phospholipid bilayer with embedded proteins. They exhibit selective permeability and fluidity, and they participate in signaling, energy transduction, and compartmentalization of cellular processes.

In technology: Synthetic membranes are engineered barriers used in filtration and separation, including polymeric, ceramic, and graphene-based systems. They enable processes such as reverse osmosis, microfiltration, nanofiltration, gas separation, and dialysis, depending on pore size and membrane chemistry.

Structure and principles: Membranes are characterized by selective permeability, transport mechanisms (diffusion, facilitated diffusion, active transport), and the fluid mosaic model. Performance is described by properties such as permeability, selectivity, fouling resistance, and mechanical stability.

Etymology and usage: The Polish noun membranie refers to membranes; the English counterpart is membrane. In English literature, membranie is uncommon; contexts often specify biological membranes or synthetic membranes. The term highlights the common concept of a boundary layer that governs the exchange of substances between adjoining environments.
