Thin film over thin porous layer influenced by lens permeability / Nur Fauzana Mahadhir

A thin film is a continuous layer of material that is applied to or interacts with porous substrates. Porous layers act as porous membranes to allow certain substances to pass through affecting the behaviour of thin films on top of them. A thin film is applied over thin porous layers to examine the...
