I started working in research and development of magnetic nanoparticles mostly magnetite Fe3
O4 in 1980. The process of making the extremely small magnetic particles required to block the interference with the electromagnetic fields ( EMF ) around the working places.
The nanoparticles magnetite are used to make magnetic liquids. One of the magnetic liquids applications was to make Faraday enclosure or materials like paint, plastic all used to block and shield EMF in houses buildings and many other applications.
Nanoparticles are part of advanced material which are totally different in chemical and physical properties. A nano magnetite particle has a huge surface to volume ratio. One cubic centimeter of nano particles can cover a surface of over 7000 square meters ( a football stadium is about 4000 square meters.
I am a chemical engineer specializing in electrochemistry bringing more than 40 years experience in research development including , materials to absorb, reflective or block and shield EMR/EMF.
My wife Nicole is also a chemical engineer specialized in environmental testing of contaminated land, water and air with very toxic chemicals. We had our own Company serving the area of New England, New-York, Pennsylvania and California for more than 30 years
