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.

UNIVERSITY PARK, Pa. — A team led by researchers at Penn State recently received a $2,491,443 grant from the Department of Energy’s (DOE) Industrial Efficiency and Decarbonization Office (IEDO) to reduce emissions and increase thermal efficiency in industrial systems. The team, which includes researchers at Saint-Gobain Ceramics & Plastics Inc., plans to achieve these goals by developing a new ceramic heat exchanger.

UNIVERSITY PARK, Pa. — Ferroelectrics are special materials with polarized positive and negative charges — like a magnet has north and south poles — that can be reversed when external electricity is applied. The materials will remain in these reversed states until more power is applied, making them useful for data storage and wireless communication applications.

Continuously monitoring a person’s pulse can provide meaningful medical information, such as heart rate and, indirectly, blood pressure. However, pulse waves can vary dramatically from person to person and even within the same person at different times of day and during different activities. These variations make it difficult for current wearable pulse sensors to accurately record useful data, which is especially problematic for those with cardiovascular disease or high-risk factors for those diseases.
