Embedding Invisible Codes in Objects for Augmented Reality

See how objects can be fabricated with embedded codes visible only to infrared cameras to provide metadata or interact with mobile phones or augmented reality devices in this video about InfraredTags from the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL).

Americium, a metal that can visualize radiation

Americium is a manufactured radioactive metal that is solid under normal conditions. Americium is produced when plutonium absorbs neutrons in nuclear reactors or during nuclear weapons tests.

One Minute Mentor: Carbonitriding

Carbonitriding is a modified form of gas carburizing that uses additions of up to 10% ammonia into the gas carburizing atmosphere resulting in adding nitrogen to the carburized case. It produces a more consistent surface hardness profile, which improves wear resistance and toughness of the PM steel.
