Spatially Resolved Potential and Li-Ion Distributions Reveal Performance-Limiting Regions in Solid-State Batteries

October 19, 2021
Author(s)
Elliot Fuller, Evgheni Strelcov, Jamie Weaver, Michael Swift, Joshua Sugar, Andrei Kolmakov, Nikolai Zhitenev, Jabez J. McClelland, Yue Qi, Joseph Dura, Alec Talin
The performance of solid-state electrochemical systems is intimately tied to the potential and lithium distributions across electrolyte–electrode junctions that give rise to interface impedance. Here, we combine two operando methods, Kelvin probe force

Microbial interactions with silicate glasses

July 17, 2021
Author(s)
Jamie Weaver, Carolyn Pearce, Robert Koestler, Bruce Arey, Albert Kruger, Paula DePriest, Andrew Plymale
Glass alteration in the presence of microorganisms has been a topic of research for over 150 years. Researchers from a variety of disciplines, including material science, biology, chemistry, geology, physics, and cultural heritage materials preservation

Hydration of Hydrophilic Cloth Facial Coverings Greatly Increases the Filtration Properties for Nanometer and Micrometer-sized Particles

March 8, 2021
Author(s)
Christopher D. Zangmeister, James Radney, Matthew E. Staymates, Edward P. Vicenzi, Jamie Weaver
Filtration efficiencies (FE) of natural, synthetic, and blended fabrics were measured as a function of relative humidity (RH) for particles with mobility diameters between 50 nm and 825 nm. Fabrics were equilibrated at 99 % RH, mimicking conditions

Tailoring electrode-electrolyte-interfaces in lithium-ion batteries using molecularly engineered functional polymers

February 22, 2021
Author(s)
Laisuo Su, Jamie Weaver, Mitchell C. Groenenboom, Nathan Nakamura, Eric Rus, Priyanka Anand, Shikhar Krishn Jha, Joseph Okasinski, Joseph Dura, B Reeja-Jayan
Electrode−electrolyte interfaces (EEIs) affect the rate capability, cycling stability, and thermal safety of lithium-ion batteries (LIBs). Designing stable EEIs with fast Li+ transport is crucial for developing advanced LIBs. Here, we study Li+ kinetics at

Niche partitioning of microbial communities at an ancient vitrified hillfort: implications for vitrified radioactive waste disposal

August 30, 2020
Author(s)
Andrew Plymale, Jacqueline Wells, Carolyn Pearce, Colin Brislawn, Emily Graham, Tanya Cheeke, Jessica Allen, Sarah Fansler, Bruce Arey, Mark Bowden, Danielle Saunders, Vincent Danna, Kimberly Tyrrell, Jamie Weaver, Rolf Sjoblom, Rick L. Paul, John McCloy, Eva Hjarthner-Holdar, Mia Englund, Erik Ogenhall, David Peeler, Albert Kruger
A pre-Viking era vitrified hillfort, Broborg, provides a habitat analogue for disposed radioactive waste glass and shows strong niche partitioning among the organisms involved in glass alteration. Microbes cannot be eliminated from radioactive waste

Low energy cross section measurement of the 10B(a;n)13N reaction and its impact on neutron production in 1st generation stars

February 26, 2020
Author(s)
Q Liu, M Febbraro, R.J. deBoer, S. Aguilar, A Boeltzig, Y Chen, M Couder, J Gorres, Jamie Weaver, K. T. Macon, M. Wiescher, K. Manukyan, L. Morales, S Pain, W. A. Peters, C. Seymour, G. Seymour, R. Toomey, B. Vande Kolk
Nucleosynthesis in the fi rst generation of massive stars offer a unique setting to explore the creation of the fi rst heavier nuclei in an environment free of impurities from earlier stellar generations. In later generations of massive stars, hydrogen

High-Throughput Exploration of Lithium-Alloy Protection Layers for High-Performance Lithium-Metal Batteries

February 13, 2020

Jamie L. Weaver, Kedar Manandhar, Yaoyu Ren, Drew Stasak, Huilong Hou, Dylan Kirsch, Suchismita Sarker, Apurva Mehta, Saydul Sardar, Muye Xiao, Carlos Le?n, Gus Hart, Takeshi Sunaoshi, John Lemmon, Ichiro Takeuchi
To realize high specific capacity Li-metal batteries, a protection layer for the Li-metal anode is needed. We are carrying out combinatorial screening of Li-alloy thin films as the protection layer which can undergo significant lithiation with minimum

Measurement of the 10B(?,n0)13N cross section at E? ? 3.6 MeV and its application as a diagnostic at the National Ignition Facilit

September 3, 2019

Q Liu, M Febbraro, R.J. deBoer, A Boeltzig, Y Chen, C Cerjan, M Couder, B Frentz, G Gilardy, J. Gorres, E. A. Henry, E. Lamere, K. T. Macon, K. Manukyan, L. Morales, P. D. O'Malley, S Pain, W. A. Peters, D. Schneider, C. Seymour, R. Toomey, B. Vande Kolk, Jamie Weaver, M. Wiescher
The National Ignition Facility provides the opportunity to study nuclear reactions under controlled conditions at high temperatures and pressures at a level never before achieved. However, the time scale of the DT implosion is only a few nanoseconds

Near-Surface Elemental Analysis of Solids by Neutron Depth Profiling

December 31, 2018
Author(s)
Jamie Weaver, Robert Gregory Downing
Neutron Depth Profiling (NDP) is an analytical nuclear technique for the determination of elemental mass as a function of depth into a sample's surface. It is suitable for characterizing a few select elements in most solid materials to depths of
