The preparation of the substrate comprises cleaning, development of a rough surface and sometimes preheating to guarantee mechanical anchorage at microwelding sites.
This comprises cleaning the body, fingerboard, back of the neck, and headstock.
This comprised data cleaning, data validation, and sorting.
Applying the previously defined criteria, we prioritized ingredients among the large number of ingredient comprising cleaning mixtures.
The PVD technology of the pilot line comprises different plasma cleaning processes, thermal evaporation by means of radiation heating as well as electron beam evaporation.
Exemplarily, coating or adhesive bonding processes rely on a sequence of layer-oriented procedures comprising substrate cleaning, pre-treatment and, finally, the application of a fluid system which during the manufacture wets the substrate surface, hardens and forms a coating or an adhesive layer [1-4].
At the GMI, sample pre-treatment comprised extensive mechanical cleaning of the surface of the bones and teeth with UV-irradiated sandpaper and/or sterile scalpel blades, followed by a 20 min soak in sodium hypochlorite solution (≥4% active chlorine), and one washing step each in sterile water and absolute ethanol.
Regular database cleaning comprised checks for inconsistencies relative to source documents when necessary, and all patient files were maintained securely throughout the program for this purpose.
To prepare the MWCNTs covered with continual Ni P layers, a pre-treatment procedure comprised of acid-cleaning, sensitization and activation has been developed.
The syringe cleaning procedure comprised a washing step before and after sample injection, using methanol as washing solution.
