Stacking Collodion Layers When Making Films

Protein Films on Collodion Membranes

1. Collodion membranes of high permeability were found to adsorb weighable amounts of gelatin and egg albumin from solution at 37 degrees C. 2. The effect of protein concentration could be expressed fairly well by a hyperbolic equation proposed by Langmuir for the adsorption of gases by a plane surface, while the usual parabolic adsorption equation of Freundlich did not fit the results. 3. In c...

Sensor based registration and stacking of electronic substrate layers

Substrates for most of today's electronic products contain many wiring layers which are individually fabricated, mechanically registered with one another, and laminated together. Alignment tolerances of 0.05 mm to 0.1 mm are su cient to register the vertical connection pads or vias on each layer. More aggressive designs of the future will, however, require manufacturing accuracies of at least a...

Experimental determination of layers films thicknesses

The determination of particle induced x-ray emission (PIXE) cross sections and the concentration of elements in a material require the knowledge of the target sample thickness. In this aim, measurements of the thickness by three different methods have been performed. These are absorption of X-rays by a 55 Fe source, transmission of alpha particles by a 241 Am source and Rutherford backscatterin...
