Peak Nanosystems makes Northeast Ohio home for cutting-edge nanotechnology Contributed photo Peak Nanosystems uses extremely thin layers of polymers to manipulate materials in new ways. The company has two locations with 37 employees in Ohio. Peak Nanosystems LLC is using small-scale technology to make a big impact. The company uses extremely thin layers of polymers to manipulate materials in new ways, allowing it to create products that can be lighter, smaller, more exact. It's "engineering at the virus level," CEO Jim Welsh said. And it's doing that work in Northeast Ohio. Welsh said he wants Peak Nano to be the "world's leading commercialization engine for nanotechnology." It's getting its start in optics, but he sees opportunities in a variety of other industries, like electric vehicles or food packaging.
