Biosensing platform simultaneously detects vitamin C and SARS-CoV-2
By Mariah Lucas
UNIVERSITY PARK, Pa. — In the COVID-19 pandemic era, at-home, portable tests were crucial for knowing when to wear a mask or isolate at home. Now, Penn State engineering researchers have developed a portable and wireless device to simultaneously detect SARS-CoV-2, the virus that causes COVID-19, and vitamin C, a critical nutrient that helps bolster infection resistance, by integrating commercial transistors with printed laser-induced graphene.
Getting over the hump to improve fuel cell manufacturing
By Sarah Small
UNIVERSITY PARK, Pa. — Fuel cells offer a form of clean energy across many sectors and are of particular interest in vehicles, where they produce no emissions. The production of fuel cells requires the use of a rapid laser welding process; however, welding at too high a speed results in humping, marked by surface irregularities on the weld seam.
