Paul Ohodnicki Receives $1 Million Grant to Innervate Pipelines | Pittwire

Thursday, February 4, 2021 Share Research led by Paul Ohodnicki, associate professor of mechanical engineering and materials science at the University of Pittsburgh Swanson School of Engineering, recently received $1 million in funding to utilize Pitt-developed optical fiber sensor technology as the “nerves” of critical infrastructure, such as natural gas pipelines, to mimic the principle of a nervous system. Ohodnicki also teaches in the electrical and computer engineering department. The research will embed optical fiber sensors internal to the pipeline to create an “innervated” pipeline system that enables monitoring the integrity of the pipes through acoustic and vibrational signatures of defects. By combining the embedded sensors with artificial intelligence and machine learning and integrating into an overarching digital twin of the pipeline system, an “intelligent” pipeline can be realized that allows for targeted in-situ repairs of defects.

Research shows immediate phase of blood vessel restructuring after aneurysm

Research shows immediate phase of blood vessel restructuring after aneurysm Hitting a pothole on the road in just the wrong way might create a bulge on the tire, a weakened spot that will almost certainly lead to an eventual flat tire. But what if that tire could immediately begin reknitting its rubber, reinforcing the bulge and preventing it from bursting? That s exactly what blood vessels can do after an aneurysm forms, according to new research led by the University of Pittsburgh s Swanson School of Engineering and in partnership with the Mayo Clinic. Aneurysms are abnormal bulges in artery walls that can form in brain arteries. Ruptured brain aneurysms are fatal in almost 50% of cases.

Shifting gears toward chemical machines

The gear is one of the oldest mechanical tools in human history1 and led to machines ranging from early irrigation systems and clocks, to modern engines and robotics. For the first time, researchers at the University of Pittsburgh Swanson School of Engineering have utilized a catalytic reaction that causes a two-dimensional, chemically-coated sheet to spontaneously morph into a three-dimensional gear that performs sustained work.
