1. Electromagnetic wave barrier paint:

• One-component, two-component, weather-resistant carbon nanocoating that shields 99.99% of incoming electromagnetic waves in the RF (100 - 3000 MHz) and X-band (8-12 GHz) frequency bands).

• Intended use: Safely protect equipment and people from the effects of electromagnetic waves in the RF bands (100 MHz - 3000 MHz) and X-band (8-12 GHz)

2. Zero valence metal nanoparticles (trace elements):

• Fe⁰, Cu⁰, Co⁰ nanoparticles have average size 30-70 nm, purity over 99.6%

• Purpose of use: Treat seeds/seedlings, stimulate plant growth and development, increase disease resistance, increase yield by 20-30%.

3. Catalytic treatment of harmful emissions:

• The K/MnxOy, KMnFexOy, Au/Co3O4 catalyst complex impregnated on a high-aluminum ceramic base.

• Purpose of use: Application in medical waste incinerators, capable of converting and removing harmful emissions (NO, Nox, CO...)
