LEDs go ultraviolet with nanocrystal core

February 27, 2012 3:49 am | News | Comments

A multinational team of scientists has developed a process for creating glass-based, inorganic light-emitting diodes (LEDs) that produce light in the ultraviolet range. If successfully integrated into biomedical devices, these would be the first robust, cheap to produce, and chemically stable LEDs to operate in the medically-useful UV spectrum.

Lead-free solder becomes top earner for Ames, ISU

January 5, 2012 11:41 am | News | Comments

Fifteen years ago, an environmentally-friendly solder developed by Ames Laboratory became the first viable, cost-effective alternative to tin-lead solder. The successful tin-silver-copper alloy has now replaced an advanced mass spectrometer as the top royalty generator for both Ames and Iowa State University.
