Its main purpose is to resist hydrostatic pressure exerted by moisture in the liquid state. Waterproofing membranes consist of waterproof plastic, rubber, or coated-fabric materials. The materials are ...

Nanoporous membranes with atomic-scale holes smaller than one-billionth of a meter have powerful potential for decontaminating polluted water, pulling valuable metal ions from the water, or for ...

The Visking tubing is the selectively permeable membrane. Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated ...

The net movement of water from a region of high water concentration to a region of low water concentration through a selectively permeable membrane. This means osmosis is a special case of ...
