The researchers discussed this distinction, saying the the lithium carbonate shapes the graphene sheete, isolating them from each other and thereby preventing the formation of graphite. Then after the lithium carbonate is washed out with acid, only the 3-D graphene remains.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
