Latest Patents

Vinogradov’s listed patent, “Material for Electrodes of Low Temperature Plasma Generators,” describes a porous metal matrix impregnated with an electron-emitting material. The matrix combines copper and iron powders, while a Group IIIB metal component, such as yttrium oxide (Y₂O₃), serves as the electron-emitting material. One example composition contains 3–30% iron, 0.05–1% Y₂O₃, and copper as the remainder by mass.

The patent describes complementary roles for these ingredients. Copper supports heat and electrical conduction, iron reduces copper evaporation during plasma generation and helps improve electrode strength and service life, and Y₂O₃ lowers the electron work function and supports stable arc operation. The material is intended for electrodes in low-temperature AC plasma generators, with potential applications in treating liquid organic, medical, and municipal waste; decontaminating low-level radioactive waste; and destroying chemical weapons and toxic agents.
