Generally, as these vehicles contain dedicated sensors,<br />
controllers, actuators and remote control systems they are<br />
expensive enough to be used by large companies that afford<br />
them. The authors succeeded in devising a configuration based<br />
on off-the-shelf components, thus drastically reducing the<br />
building costs for similar performances.<br />
The developed ROV is meant to be used mainly for inspection of<br />
the vessel’s hull and for emergency applications in shallow<br />
waters, port basins or lakes) replacing in these situations the need<br />
of divers.<br />

New formulations using a combination of enzymes (three<br />
different proteases) and ionic liquids are proposed for the<br />
removal of proteinaceous varnish layers (egg white, animal<br />
glue, isinglass and casein). The treatment was applied on<br />
documented reconstruction of painted surfaces and gold leaf<br />
gilding. The use of ionic liquids (ILs) defined as “green<br />
Description solvents” as an alternative solvent to enzymes is an area in<br />
conservation science with a large number of possibilities: the<br />
ionic liquid is a material that can be designed (cation-anion<br />
combinations) to adjust to different requirements such as<br />
improvement of enzyme cleaning effectiveness, surface<br />
compatibility, and safety for the user.<br />
To monitor and analyze the effectiveness of each<br />
formulation, a novel multi-scale non-invasive approach based<br />
