Charles M. Lieber, Hyman professor of chemistry in the Faculty of Arts and Sciences, and Donhee Ham, assistant professor of electronic engineering in the Division of Engineering and Applied Sciences, led a interdisciplinary team of chemists and engineers on the project, which was described in the journal Nature last week...
Although scientists have been working with nanowires and nanotubes for years, Lieber and Ham were able to make use of recent research into the physics of nanowire performance. Ham noted that this breakthrough was only possible because of the collaboration between chemists and engineers. Lieber developed high-yield nanowires with unique organizational structures while Ham provided circuit design expertise and assembly techniques...
According to Ham, this technology can be applied to almost any communications device and “can be considered a complimentary alternative,” to parts of current cell phone technology, allowing manufacturers to decease cell phone size...
...first word to the outside world came from Armero's mayor, Ramn Antonio Rodrguez, 34. A ham operator, he was on the radio to a fellow ham in Ibagu, 60 miles to the south, when Nevado del Ruiz erupted, scattering rock and ashes across the Lagunilla Canyon. The mayor was calmly describing the event when suddenly he shouted, "Wait a minute. I think the town is getting flooded." Those words were his last...
...immigrants. Within hours after news of the disaster reached the city, the local Colombian consul general, Roberto Garca Archila, was swamped with aid offers. Less than 24 hours after the eruption, an Avianca Boeing 727 left Miami International Airport laden with privately donated medical supplies. Meanwhile, Spanish-speaking ham-radio operators in Miami were relaying messages from Colombia to the Florida consulate, where hundreds of anxious Colombians kept a vigil, hoping for news of relatives and other loved ones in the danger zone...
