He announced the results of his works in Polish, German and French scientific journals. This was followed by rapid adaptation of Mościcki’s discoveries and inventions regarding the dielectric properties, the construction of technical high voltage capacitors, the construction of fuses protecting the electrical transmission lines against lightning, production of nitric acid from the air, the construction of devices used for absorption of gaseous substances, etc. His experience Mościcki transferred to Lvov.
