Film remover

Because the corrosion resistance of lead and lead alloys is associated with the formation of the protective corrosion film, removal of the film in any way causes rapid attack. Thus the velocity of a solution passing over a surface can lead to significantly increased attack, particularly if the solution contains suspended particulate material. Lead is also attacked rapidly in the presence of high velocity deionised water. The lack of dissolved minerals in such water prevents the formation of an insoluble protective film. In most solutions, lead and lead alloys are resistant to galvanic corrosion because of the formation of a nonconductive corrosion film. In contact with more noble metals, however, lead can undergo galvanic attack which is accelerated by stray electrical currents. 

Film is locally removed by dissolution, surface shear stress or particle/bubble impact but it can repassivate. Erosion corrosion rate is a function of the frequency of film removal, bare metal dissolution rate and subsequent repassivation rate. 

Raw throughput improvement can be achieved by reducing the amount of material that must be polished away, increasing film removal rates, and increasing the wafer-handling efficiency. Wafer-handling efficiency is addressed in the following sections. 

Identify the protein spots as usual, i.e., by staining, autoradiography, gel overlay, or Western blot. In the latter case the gel must be separated from the GelBond foil prior to electrotransfer. For this purpose a film remover (Gorg 2003, Fig. 19) is used The gel is placed on the cylindrical remover with foil down, clamped on an edge, and a thin stainless steel or nylon wire is pulled between foil and gel towards to your body. Cover the gel with the wetted blotting membrane (cf Protocol 2.4.3) and transfer membrane as well as gel to the blotting apparatus. 

A 3/8 inch diameter aluminum or titanium-tungsten dot pattern WLs fabricated on top of the cured polyimide film to make electrical leakage to substrate measurements for pinhole density estimation. An etch decoration technique was used to visually determine pinhole densities in polyimide films. The polyimide film was cast on substrates comprised of a layer of 200 nm thick alumimmi on blue colored field oxide with a grid pattern for area computation. Replicate holes were etched in the aluminum by a hot phosphoric acid solution. With the polyimide film removed, a good visual contrast was achieved for pinhole density counting.

With idealized assumptions inherent losses due to interconnection are between about 5 and 8% depending on the front TCO conductivity and the width of the interconnection structure. Additional losses to consider in module production compared to laboratory type small area test cells appear due to production type processes, nonuniformity, and peripheral film removal [8,70]. 

We have not yet explored the mechanism of the irreversible bleaching in any detail. Some film removal is visually evident.

Figure 2 is the same type of film removed after 14 days of intramuscular implantation. Here the collagen is fragmented and infiltrated with infiammatory cells. After 21 days, all control films disappeared except for the ones prepared from a mixture of insoluble collagen fiber and enzyme-solubilized collagen. Some of these remained for 30 days.
