Polyoxovanadates as Precursors for the Synthesis of Colloidal Multi-Metal Oxide Nanocrystals

March 31, 2022
Author(s)
Adam Biacchi, Lucas Johnson, Ashley Sweet, Eric Cal, Angela R. Hight Walker, Matthew Buck, Luke Barrante
Colloidal multi-metal oxide nanocrystals that contain the element vanadium are attractive materials for enabling diverse technologies. Few nanocrystal systems are synthetically well-developed, however, which is attributable to a scarcity of molecular

Synthesis, crystal structure, and physical properties of BaSnS2

February 11, 2022
Author(s)
Wilarachchige Gunatilleke, Andrew May, Angela R. Hight Walker, Adam Biacchi, George Nolas
Phase-pure BaSnS2, with space group Pn21/c, was synthesized and the structural and physical properties were investigated. The thermal properties and optical measurements are reported for the first time. The Debye temperature and Sommerfeld coefficient were

Dependence of Single-Wall Carbon Nanotubes Alignment on the Filter Membrane Interface in Slow Vacuum Filtration

January 22, 2022
Author(s)
Jeffrey Fagan, Angela R. Hight Walker, Adam Biacchi, Andrei Kolmakov, Zia Macdermid, William D. Rice, Joshua Walker, Thomas Searles
The recent development of slow vacuum filtration (SVF) technology has shown great promise for reproducibly producing high-quality, large-area aligned films of single-wall carbon nanotubes (SWCNTs) from solution-based nanotube dispersions. In contrast to

Advanced characterization of magnetization dynamics in iron oxide magnetic nanoparticle tracers

January 5, 2022
Author(s)
Thinh Bui, Adam Biacchi, Brianna Bosch Correa, Cindi L. Dennis, Weston L. Tew, Angela R. Hight Walker, Solomon I. Woods
Characterization of the magnetization dynamics of single-domain magnetic nanoparticles (MNPs) is important for magnetic particle imaging (MPI), magnetic resonance imaging (MRI), and emerging medical diagnostic/therapeutic technologies. Depending on

Synthesis of Mixed-Valent Lanthanide Sulfide Nanoparticles

August 23, 2021
Author(s)
Pricilla Glaser, Orlando Stewart, Rida Atif, Dane Asuigui, Joel Swanson, Adam Biacchi, Angela R. Hight Walker, Gregory Morrison, Hans-Conrad zur Loye, Sarah Stoll
In targeting reduced valence lanthanides, we report the first nanoparticle synthesis of the mixed-valent ferromagnets Eu3S4 and EuSm2S4. Using divalent lanthanide halides with bis(trimethylsilyl)sulfide and oleylamine, we prepared nanoparticles of EuS

The joint automated repository for various integrated simulations (JARVIS) for data-driven materials design

November 12, 2020
Author(s)
Kamal Choudhary, Kevin Garrity, Andrew C. Reid, Brian DeCost, Adam Biacchi, Angela R. Hight Walker, Zachary Trautt, Jason Hattrick-Simpers, Aaron Kusne, Andrea Centrone, Albert Davydov, Francesca Tavazza, Jie Jiang, Ruth Pachter, Gowoon Cheon, Evan Reed, Ankit Agrawal, Xiaofeng Qian, Vinit Sharma, Houlong Zhuang, Sergei Kalinin, Ghanshyam Pilania, Pinar Acar, Subhasish Mandal, David Vanderbilt, Karin Rabe
The Joint Automated Repository for Various Integrated Simulations (JARVIS) is an integrated infrastructure to accelerate materials discovery and design using density functional theory (DFT), classical force-fields (FF), and machine learning (ML) techniques

Design and Engineering Colloidal Magnetic Particles for Nanoscale Thermometry

September 2, 2020
Author(s)
Adam J. Biacchi, Thinh Q. Bui, Cindi L. Dennis, Solomon I. Woods, Angela R. Hight Walker
Thermometry based on magnetic nanoparticles (MNPs) is an emerging technology that allows for remote temperature measurements throughout a volume that are impossible to achieve using conventional probe-based or optical methods. This metrology is based on

High-throughput Density Functional Perturbation Theory and Machine Learning Predictions of Infrared, Piezoelectric and Dielectric Responses

May 27, 2020
Author(s)
Kamal Choudhary, Kevin F. Garrity, Vinit Sharma, Adam J. Biacchi, Francesca M. Tavazza, Angela R. Hight Walker
In this work, combining high-throughput (HT) density functional perturbation theory and supervised machine learning approaches, we explored the territory of compounds with interesting infrared, piezoelectric and dielectric properties. We have computed Γ

Global alignment of solution-based single-wall carbon nanotube films via machine-vision controlled filtration

September 11, 2019
Author(s)
Jeffrey A. Fagan, Angela R. Hight Walker, Adam J. Biacchi, Joshua S. Walker, William D. Rice, Thomas Searles, Valerie A. Kuehl
Over the past decade, substantial progress has been made in the chemical processing (chiral enrichment, length sorting, handedness selectivity, and filling substance) of single- wall carbon nanotubes (SWCNTs). Recently, it was shown that large

Correlating anisotropic mobility and intermolecular phonons in organic semiconductors to investigate transient localization

March 19, 2019
Author(s)
Emily G. Bittle, Adam J. Biacchi, Lisa A. Fredin, Andrew A. Herzing, Thomas C. Allison, Angela R. Hight Walker, David J. Gundlach
Charge transport in organic semiconductors is governed by a mix of polaron hopping and band- like transport mechanisms. The energy of polaron hopping and formation are similar in magnitude to the energies of inter- and intra- molecular modes, which points
