Self-repairing materials
When a person suffers a minor wound, the human body reacts to close the opening, sending the blood platelets needed to the affected area -- and with no need in many cases for any external coagulant substance to be employed. This reaction of nature to damage suffered was the starting point for the development of self-repairing polymer materials with the capacity of recovering a good part of the properties lost and with no or with minimal external help. (2008-04-17)

Printing with sound
Harvard University researchers have developed a new printing technology that uses sound waves to control the size of liquid droplets independent of fluid viscosity. This approach could greatly broaden the types of liquids, including biopharmaceuticals, that can be printed drop-on-demand. The researchers used sound waves to generate a highly confined force at the tip of the printer nozzle, which pulls the droplet. The higher the amplitude of the sound waves, the smaller the droplet size. (2018-08-31)
