WQI News

The first-ever WQI seminar took place on September 21!

We kicked off our first-ever WQI seminar last week hosting Lincoln Carr from the Colorado School of Mines!

The seminar series shares new ideas in QISE with an audience that is looking to advance their understanding of these concepts.

We look forward to welcoming our guests every month and the continued engagement of our faculty and students!

Prof. Soley receives ACS Kavli Emerging Leader Award

Congratulations to Micheline Soley for receiving the American Chemical Society Kavli Emerging Leader Award!

The Kavli Foundation Lecture Series recognizes groundbreaking discoveries by scientists tackling many of the world’s mounting challenges; and in particular, the Emerging Leader Award is for distinguished younger scientist who is highly regarded by their peers for significant contributions to an area of chemistry and multidisciplinary areas of chemistry.  The award is a keynote lecture and the only Kavli young investigator talk at the American Chemical Society meeting.

Smooth sailing for electrons in graphene

two panels in heat-map style. both panels have circles in the middle. The panel on the left has more yellow and red to the left of the circle and a bright yellow ring around the circle; the right panel has a less sharp transition of colors from left to right and no bright ring around the circles.

Physicists at the University of Wisconsin–Madison directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results, which will appear in the journal Science on Feb. 17, have applications in developing new, low-resistance materials, where electrical transport would be more efficient.

Graphene, an atom-thick sheet of carbon arranged in a honeycomb pattern, is an especially pure electrical conductor, making it an ideal material to study electron flow with very low resistance. Here, researchers intentionally added impurities at known distances and found that electron flow changes from gas-like to fluid-like as temperatures rise.

“All conductive materials contain impurities and imperfections that block electron flow, which causes resistance. Historically, people have taken a low-resolution approach to identifying where resistance comes from,” says Zach Krebs, a physics graduate student at UW–Madison and co-lead author of the study. “In this study, we image how charge flows around an impurity and actually see how that impurity blocks current and causes resistance, which is something that hasn’t been done before to distinguish gas-like and fluid-like electron flow.”
