Concerted Electron-Ion Transport by Polyacrylonitrile Elucidated with Reactive Deep Learning Potentials
Rajni Chahal-Crockett, Michael D. Toomey, Logan T. Kearney +4
Charge transport in polymers, such as polyacrylonitrile (PAN), is crucial for electronics and energy storage. For instance, PAN can transport cations e.g., Li+, by facilitating dyn…
Probing Boron Vacancy Defects in hBN via Single Spin Relaxometry
Alex L. Melendez, Ruotian Gong, Guanghui He +14
Spin defects in solids offer promising platforms for quantum sensing and memory due to their long coherence times and optical addressability. Here, we integrate a single nitrogen-v…
Detecting half-quantum superconducting vortices by spin-qubit relaxometry
Gábor B. Halász, Nirjhar Sarkar, Yueh-Chun Wu +3
Half-quantum vortices in spin-triplet superconductors are predicted to harbor Majorana zero modes and may provide a viable avenue to topological quantum computation. Here, we intro…
Cross-scale Modeling of Polymer Topology Impact on Extrudability through Molecular Dynamics and Computational Fluid Dynamics
Yawei Gao, Jan Michael Carrillo, Logan T. Kearney +7
Understanding how polymer topology influences melt extrudability is critical for advancing material design in extrusion-based additive manufacturing. In this work, we develop a bot…
Chemically resolved nuclear magnetic resonance spectroscopy by longitudinal magnetization detection with a diamond magnetometer
Janis Smits, Yaser Silani, Zaili Peng +7
Non-inductive magnetometers based on solid-state spins offer a promising solution for small-volume nuclear magnetic resonance (NMR) detection. A remaining challenge is to operate a…
Time-resolved diamond magnetic microscopy of superparamagnetic iron-oxide nanoparticles
B. A. Richards, N. Ristoff, J. Smits +19
Superparamagnetic iron-oxide nanoparticles (SPIONs) are promising probes for biomedical imaging, but the heterogeneity of their magnetic properties is difficult to characterize wit…
