Researchers from North Carolina State University have developed a new technique for creating stronger, lightweight magnesium alloys that have potential structural applications in the automobile and aerospace industries.
Engineers constantly seek strong, lightweight materials for use in cars and planes to improve fuel efficiency. Their goal is to develop structural materials with a high “specific strength,” which is defined as a material’s strength divided by its density. In other words, specific strength measures how much load it can carry per unit of weight. (more…)
Shark migrations studied with underwater robot along Delmarva Peninsula
University of Delaware researchers are using an underwater robot to find and follow sand tiger sharks that they previously tagged with transmitters. The innovative project is part of a multi-year partnership with Delaware State University to better understand the behavior and migration patterns of the sharks in real time.
“In the past week our new, specially equipped glider OTIS – which stands for Oceanographic Telemetry Identification Sensor – detected multiple sand tiger sharks off the coast of Maryland that were tagged over the past several years,” said Matthew Oliver, assistant professor of oceanography in UD’s College of Earth, Ocean, and Environment. “This is the first time that a glider has found tagged sharks and reported their location in real time.” (more…)
