Shay and Shannon's graduation is a family reunion of sorts, since the two were undergraduates together at Tech some 20 years ago.
By using an electrochemical etching process on a common stainless steel alloy, researchers have created a nanotextured surface that kills bacteria while not harming mammalian cells. If additional research supports early test results, the process might be used to attack microbial contamination on implantable medical devices and on food processing equipment made with the metal.
When Emma Siegfried graduates this weekend, she’ll be the latest in a line of family members who have been attending Georgia Tech for more than 100 years.
A molecular-sized brush that looks like a shoe brush has properties with great potential for the materials industry and medicine, but polyelectrolyte brushes can be sensitive, and getting them to work right tricky. New research shows what can make them break down, but also what can get them to systematically recover.
