The invention relates to a process for preparing an active element for gas sensors. According to the invention, the process consists in the physical immobilization of AchE enzyme in and on the surface of a polymeric film of polyethylenimine, using the laser evaporation technique, resulting in a layer with an increased number of enzymes bound per adsorbent unit, with sizes in the micron range, of controlled characteristics and enhanced chemical stability.

The invention relates to a method for determining the energy distribution of a proton beam, said method being used as a diagnostic means for the protons produced in plasma inertial confinement or Z-pinch plants, which result from the interaction between plasma and high intensity laser beams, existing in cosmic radiation, generated by medical equipments for proton therapy, as well as the monitoring of environments subjected to ionizing radiation, such as space stations, spaceships and spacecrafts.

The invention relates to a hernia-repair mesh, coated with thin layers of nanocomposite materials consisting of polyethylene oxide polymer PEO and carbon nanotubes CNT and to a process for making the same. According to the invention, the mesh consists of a commercial macroporous monofilament net made of polypropylene or polyester, with the pore size > 1 mm, coated, at the exterior, with a continuous homogenous thin adherent nanocomposite film based on polyethylene oxide and carbon nanotubes. The claimed process has the following stages: a.
