Hydrogen-powered aviation is gaining momentum as a sustainable alternative to fossil-fueled flight, yet the field faces complex technological and operational challenges. To better understand commercial innovation pathways, this study analyzes the claims sections of 166 hydrogen aviation patents issued between 2018 and 2024. Unlike prior studies that focused on patent titles or abstracts, this approach reveals the protected technical content driving commercialization.
Suicide is a leading cause of death among workingage adults in the United States. It deeply impacts workers, families, and communities. Fortunately, like other workplace fatalities, suicides can be prevented.
Recent research conducted at South Dakota State University shows that E. coli contamination of stormwater runoff was reduced by an average of more than 44%, and phosphate levels were also significantly reduced in a pilot stormwater filtration that used steel chips and steel slag as a filtration media.
Research at South Dakota State University to better understand stream flows will lead to improved designs for bridges, culverts, and other infrastructure elements that are subject to erosion and scour.
