Effect of network connectivity on behavior of synthetic Broborg Hillfort glasses

September 2, 2022
Author(s)
Jose Marcial, Maria Cicconi, Carolyn Pearce, Jaroslav Klouzek, James Neeway, Richard Pokorny, Miroslava Vernerova, John McCloy, Emily Nienhuis, Rolf Sjoblom, Jamie Weaver, Russell Hand, Pavel Hrma, Albert Kruger
There is wide industrial interest in developing robust models of long-term (>100years) glass durability. Archeological glass analogs, glasses of similar composition, and alteration conditions to those being tested for durability can be used to evaluate and

ALD deposited amorphous alumina coatings can slow glass alteration

August 31, 2022
Author(s)
Miriam Hiebert, Jamie Weaver, Thomas Lam, Nicole Little, Ethan Hyde, Edward Vicenzi, Ray A. Phaneuf
Atomic layer deposited (ALD) amorphous aluminum oxide and titanium oxide coatings have been investigated for use in reducing the rate of silicate glass alteration. Mass spectrometric analysis of leachate from elevated temperature aqueous immersion

Why big data and compute are not necessarily the path to big materials science

August 30, 2022
Author(s)
Naohiro Fujinuma, Brian DeCost, Jason Hattrick-Simpers, Sam Lofland
Applied machine learning has rapidly spread throughout the physical sciences. In fact, machine learning-based data analysis and experimental decision-making have become commonplace. Here, we reflect on the ongoing shift in the conversation from proving

Effects of local processing parameters on microstructure, texture, and mechanical properties of electron beam powder bed fusion manufactured Ti-6Al-4V

August 27, 2022
Author(s)
Edwin Schwalbach, Jake Benzing, Vikas Sinha, Todd Butler, Adam Pilchak, Kevin Chaput, Norman Schehl, Reji John, Nik Hrabe
Electron beam powder bed fusion scan strategies for parts or part groupings of various sizes and scan line lengths have been found to inadvertently lead to significant variations in crystallographic texture and mechanical properties for Ti–6Al–4V. This

Relative effects of polymer composition and sample preparation on glass dynamics

August 17, 2022
Author(s)
Christopher Soles, Amanda L. Forster, Katherine Evans, Madhusudan (Madhu) Tyagi, Robert M. Elder, Timothy Sirk, Joseph Dennis, Kanae Ito, Osama Yamamuro, Hiroshi Akiba
Modern design of common adhesives, composites and polymeric parts makes use of polymer glasses that are stiff enough to maintain their shape under a high stress while still maintaining a ductile behavior after the yield point. Typically, material

Atomically Dispersed CuNx Sites from Thermal Activation of Boron Imidazolate Cages for Electrocatalytic Methane Generation

August 12, 2022
Author(s)
Soumyodip Banerjee, Justin Gorham, Maxime Siegler, Natalia Drichko, Joshua Wright, Nicholas Bedford, Sara Thoi
Atomically dispersed heteroatom coordinated metal sites (ADMS) have been recognized as promising candidates for electrochemical conversion. Among a diverse range of molecular precursors for ADMS synthesis, framework materials are particularly interesting

The Effect of Organic Coatings in the Magnetization of CoFe 2 O 4 Nanoparticles

August 4, 2022
Author(s)
Priscyla L. Andrade, Valdeene Silva, Kathryn L. Krycka, Juscelino Leao, I-Lin Liu, Maria P. Silva, J. Albino Aguiar
Cobalt ferrite has attracted considerable attention in recent years due to the unique physical properties such as high Curie temperature, large magnetocrystalline anisotropy, high coercivity, moderate saturation magnetization, large magnetostrictive
