The COVID-19 pandemic has cast a harsh light on the urgent need for quick and easy techniques to sanitize and disinfect everyday high-touch objects such as doorknobs, pens, pencils, and personal protective gear worn to keep infections from spreading. Now scientists at the U.S.
An invention to apply plasma to frequently touched items for continuous disinfection could provide a safe, effective, non-chemical way to reduce pathogens on various surfaces such as keypads, escalator handrails, and other high-touch surfaces, inventors at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) say.
Princeton Plasma Physics Laboratory (PPPL) physicist Erik Gilson won third place at the Princeton University Keller Center’s 15th Annual Innovation Forum for his invention with a team of PPPL researchers of an advanced liquid centrifuge. The centrifuge can separate the components of a liquid for applications such as treating waste water from oil sands processing, fruit juice production, processing ink pigments and for other industrial applications.
Alex Nagy, an engineer who for four decades has been working on ways to heat and fuel plasmas in experiments aimed at harnessing the process that powers the sun and stars, was named a Distinguished Engineering Fellow by the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) at the State of the Lab address on Dec. 20.
Nagy was honored for “creative designs of plasma heating and fueling systems employed in fusion devices worldwide.” The fellowship is part of PPPL’s Distinguished Research and Engineering Fellow Program and comes with a cash award.
When it comes to car and truck engines, not much has changed since Nikolaus Otto invented the modern internal combustion engine in 1876. But the internal combustion engine could, at least theoretically, be in for a big change.
As a first-generation college student, Barbara Garcia had to figure out a lot of things on her own when applying for college. Her parents were Mexican immigrants who didn’t go to college and couldn’t help her navigate the application process, couldn’t help her study for the SATs or look over her application essays.
“Being a first-generation college student has influenced me by teaching me independence and helping me to carve my own path,” Garcia said. “I didn’t have my parents to guide me toward STEM – I just sort of found it on my own and discovered physics on my own.”
Scientists seeking to capture and control on Earth fusion energy, the process that powers the sun and stars, face the risk of disruptions — sudden events that can halt fusion reactions and damage facilities called tokamaks that house them. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), and the University of Washington have developed a novel prototype for rapidly controlling disruptions before they can take full effect.
A day-long Technology Showcase spotlighting the unique research, technical expertise, and inventions that the U.S. Department of Energy’s Princeton Plasma Physics Laboratory offers to collaborators and funders attracted a wide range of potential partners.
The Dec. 18 event highlighted several PPPL inventions and cutting-edge technologies. These included low-temperature plasma research and applications such as plasma nanosynthesis, the production of nanoparticles with plasma, as well as PPPL’s engineering capabilities in areas such as machine learning and computer simulations.
