Quantum dots are nanosized semiconductor regions with properties that act partly like large scale semiconductors and partly as though they were molecules. Quantum dots are key nanotechnology components and find use in light emitting diodes (LEDs), diode lasers, quantum computing and imaging, particularly for medical applications.
The .co has found wide use around the globe as an alternative to .com. You can see some companies using the extension in these case studies.
In the past year over 500 domains sales in this extension have been sold with an average price of about $1700.
The domain name is currently registered until July 4, 2020 (that transfers to the new owner with the domain name). After that the domain name renews at standard .co rates of $22 to $30 per year at various registrars.
Why not make an offer to start the acquisition process?
