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 material for topical treatment preventing sepsis and osteomyelitis following open bone lesions. According to the invention, the material consists of 10 antimicrobial therapeutical metal particles of Ag and Cu, respectively, having a diameter of 50 μ m or other therapeutical metal particles with a diameter of 1...4 mm with sphere shape or rounded edges, having antiseptic and nutritive effect on the bone due to the metallic ions released by the metal particles into the biological environment.
