Robert M. Dickson, an assistant professor of chemistry and biochemistry at Georgia Tech, says that silver could increase the amount of storage in optical devices. "One could potentially store more than 1 bit/data point by using color to store the information," says Dickson. For example, red and green mix to make yellow in computer displays for producing different shades of yellow. Dickson showed that clusters of silver atoms produced fluorescent emissions. Using the correct distribution of particle sizes, the multi-color emissions allow storage of more than one bit in each data point. "The different shades could be used to store more information per point. The storage density would then be related to the number of distinguishable colors," he says. He successfully demonstrated binary optical storage with the new system by writing and reading images recorded on thin films made of silver oxide.

Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Weaned on the relatively effortless connectivity of today’s massive variety of consumer electronic products, automation users in the IIoT will likely not tolerate too many competing, piecemeal standards for long. And the Industrial Internet Consortium is trying to preempt history.
