January 1, 2025
Author(s)
Marija Dubackic, Veronica Lattanzi, Yun Liu, Michael Haertlein, Juliette Devos, Emma Sparr, Sara Linse, Ulf Olsson
We have investigated the interactions between α-Synuclein (aSyn) and small unilamellar vesicles composed of a mixture of zwitterionic POPC and anionic POPS lipids. aSyn monomers spontaneously adsorb onto the anionic lipid vesicles where they adopt an α

Linking Chemical Degradation and Physical Instability of Lipid Vesicles

January 1, 2025
Author(s)
Sharareh Rezaei, Emily Blick, Kenneth Mineart, Elizabeth Kelley
Lipid vesicles are applicable in a wide variety of uses including both academic and commercial avenues. In all of these cases, it is crucial to understand and connect the chemical degradation of constituent molecules – i.e., lipids – with the physical

Methods to evaluate 3D lidars used for automated driving

January 1, 2025
Author(s)
Prem Rachakonda, Abhilash Mane, Craig I. Schlenoff, Kamel S. Saidi
Evaluating perception sensor systems for on-road autonomous vehicles is still fraught with ambiguity due to the varying and dynamic environmental factors that these vehicles encounter. The critical safety of on-road AV operations is heavily dependent on

Optimizing Electric Traction Motor Design: Analyzing the Benefits of a Circular Economy

January 1, 2025
Author(s)
Jesus Perez-Cardona, Neha Shakelly, Matthew Triebe, John Sutherland
The circular economy (CE) shifts from a linear economy (LE) to prioritize preserving value improving resource efficiency through closed loops. This shift demands product designs that facilitate repurposing and recycling, reducing waste and new material use

Time evolution of a pumped molecular magnet - a time resolved inelastic neutron scattering study
