Jeff Shield and colleagues have been investigating how to improve the heat transfer of copper used in pool boiling. In a new study, the team increased the surface area of copper by firing 4-picosecond-long laser pulses at it. However, this also coated the surface with oxides that curbed the otherwise improved heat transfer. So the team tried cleaning the surface with different acids, and found that citric acid worked best, but only when the number of laser pulses remained below a certain threshold. (11/15/21)
Markvicka team's design could curb overheating, up performance of soft electronics Blurb: A new study from a team led by Eric Markvicka has shown that embedding a silicone material with gallium-based droplets — and, crucially, embedding those droplets with microscopic spheres of hollow glass — can mostly retain the boost in heat dissipation without sacrificing the material’s lightweight pliability. This design could greatly impact things like the computing power of microelectronics and thermoregulatory garments. Markvicka's team included NCMN members Sangjin Ryu and Jeff Shield. (11/15/21)
A feature story in the 2020-2021 Nebraska Research Report described the Emergent Quantum Materials and Technologies (EQUATE) collaboration, made possible by a five-year, $20 million award from the National Science Foundation. The EQUATE project is a key component to achieving the goals of Nebraska's Quantum Science and Engineering Grand Challenge. (11/9/21)
The Nebraska Nanoscale Facility was the star of a feature story in the 2020-2021 Nebraska Research Report. The story highlights the importance of the facility for advancing academic and industry nanoscience research in the Midwest, the success the facility saw in it's first five years, and the education and outreach activities that are key to the facility's mission.
