Computer-generated database of diffusion values is shared online

July 19, 2016

University of Wisconsin–Madison engineers recently used powerful computers to quickly and accurately develop the world’s largest computed database of information about an important materials-mixing process called diffusion.

In static friction, chemistry is key to stronger bonds

November 6, 2012

Inspired by phenomena common to both earthquakes and atomic force microscopy, University of Wisconsin–Madison materials engineers have learned that chemical reactions between two silicon dioxide surfaces cause the bonds at that interface to "age," or strengthen gradually over time.

Curiosities: What is the flattest thing in the world?

March 21, 2011

The answer depends on many factors, including how the measurement is made and the scale of interest. “A mountain can look very rough, but if …

Silicon superlattices: New waves in thermoelectricity

April 1, 2009

A University of Wisconsin–Madison research team has developed a new method for using nanoscale silicon that could improve devices that convert thermal energy into electrical energy.

Mother-of-pearl: Classic beauty and remarkable strength

July 2, 2007

While the shiny material of pearls and abalone shells has long been prized for its iridescence and aesthetic value in jewelry and decorations, scientists admire mother-of-pearl for other physical properties as well.
