Gel-formed collagens are sprayable, and the plastic films so formed possess, after drying, an unusually high resistance to chemical attack by non-polar chemicals. In addition, collagens are biodegradable in the presence of certain enzymes. By varying the extent and nature of cross-linking, in some cases using additives, the elasticity and tear-resistance of such films can be modified and their resistance to chemical attack by polar species increased. This technology offers attractive possibilities, for example for temporary protection of vehicles, moving from one workshop to another or for delivery to the end-user.

In an ecological procedure fountain pen nibs are polished in a bed of walnut-shell granulates. However, residues of polishing paste and nuts remain in the ink feeder groove; a manual post processing is required. Therefore an expensively cleaning procedure was developed. For this purpose, the effectivity of different enzymes in clearing residues, as well as pure and in a mixed solution, were examined. A lipase in combination with a surfactant and an ultrasonic bath showed very good results in the solvation of polish residuals. © 2013 Springer-Verlag Berlin Heidelberg. Literatur:.
