Latest Patents

Shiryaev is credited with 1 patent, titled “Material for Electrodes of Low Temperature Plasma Generators.” The invention describes a porous metal matrix impregnated with an electron-emitting material. The matrix uses copper and iron powders, while a Group IIIB metal component, such as yttrium oxide (YO), serves as the electron-emitting material. One example composition contains 3–30% iron, 0.05–1% YO, and copper as the remainder.

In the described material, copper supports heat and electrical conduction, iron helps reduce copper evaporation during plasma generation and improves strength and service life, and YO lowers the electronic work function and helps stabilize arc burning. The material is intended for electrodes in low-temperature alternating-current plasma generators. Potential applications include treating liquid organic, medical, and municipal waste; decontaminating low-level radioactive waste; and destroying chemical weapons and toxic agents.
