Nowadays, to properly design and develop advanced materials capable to preserve for long times their performance under aggressive environments such as power generation plants, renewables, nuclear reactors and electronics of new generation, transport on ground and on space, aeronautics, catalysis, biomedical implants, the optimization of metallurgical processes involved is crucial.

The invention consists of a method and apparatus for the delivery at low pressure (equal to or less than 10^-7 Torr) of monoatomic fluorine for reaction with surfaces in an ultra-clean environment. Thanks to the low pressure values involved in the proposed method, the risks associated with the use of fluorine are reduced to a minimum.

The proposed technology offers a novel and versatile method for detecting cracks in insulating materials of electrically polarized metal devices, i.e. dielectric coatings on metals, especially in low-pressure gas environments. It uses an ionized plasma that interacts uniformly with the insulating surface, allowing to detect defects invisible to the naked eye. The detection occurs in a single test without changing the environmental conditions and without risking harmful electrical discharges.

The proposed device is a semi-transparent screen that allows simultaneous viewing of what is beyond the screen and the images projected onto its surface. It consists of two thin glass plates with reflective elements arranged as microlenses, embedded in a resin. The projector's light is reflected by the elements towards the user's eye, while external light passes through the transparent layers without distortion. The transparency and brightness of the screen can be adjusted by modifying the reflective elements.
