A. A Nanoengineered Heat Source Creates Metallic Bonds Without Thermal Damage

Narrator: This is Science Today. The development of a heat source material called NanoFoil®, which permits large and small components to metallically bond without thermal damage, was based on materials science research initiated and performed by Troy Barbee, a senior scientist at the Lawrence Livermore National Laboratory. Barbee explains that when this man-made, nanoengineered foil is ignited, all the energy goes into heating the foil and none is lost in the surrounding environment.

Barbee: And what that does is that allows you to have a very localized heat source with which you can control the amount of energy. This will enable you to put it between two pieces of materials in which to join with a solder or a braising alloy, produce the heat locally and join things which you couldn't join before because of the sensitivity to the overall heat.

Narrator: From computers to airplanes, nearly every product requires a number of joining steps during manufacturing to create durable metallic bonds that do not damage the materials being bonded. NanoFoil® is sold by Reactive NanoTechnologies for different commercial applications. For Science Today, I'm Larissa Branin.
