WebSpin Coating Process Theory. Spin coating has been used for several decades for the appli- cation of thin films. A typical process involves depositing a small puddle of a fluid resin onto the center of a substrate and then spinning the substrate at high speed (typically around 3000 rpm). Centripetal acceleration will cause the resin to spread ... WebThin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, either enhancing or reducing the reflected light.When the thickness of the film is an odd multiple of one quarter-wavelength of the light on it, the reflected waves from both surfaces interfere to cancel …

A mass balance on acetylene leads to Eq. (5) and by considering only the flux due to molecular diffusion, Eq. (6) is obtained. At the boundary in contact with the gas phase, …
WebOn the basis of the film model proposed by Nernst in 1904, Whitman [2] proposed in 1923 the two- film theory of gas absorption. Although this is a very useful concept, it is impossible to predict the individual (film) coefficient of mass transfer, unless the thickness of the laminar sublayer is known. According to this theory, the mass transfer ...
