A formal Fe(III)/(V) redox couple in an intercalation electrode

October 15, 2025
Author(s)
Hari Ramachandran, Edward Mu, Eder Lomeli, Augustin Braun, Masato Goto, Kuan Hsu, Jue Liu, Zhelong Jiang, Kipil Lim, Grace Busse, Brian Moritz, Joshua Kas, John Vinson, John Rehr, Jungjin Park, Iwnetim Abate, Yuichi Shimakawa, Edward Solomon, Wanli Yang, William Gent, Thomas Devereaux, William Chueh
Iron redox cycling between low-valent oxidation states of FeII and FeIII drives crucial processes in nature. The FeII/III redox couple charge compensates the cycling of lithium iron phosphate, a positive electrode (cathode) for lithium-ion batteries. High

February 6, 2025
Author(s)
Unay Dorken Gallastegi, Hoover Rueda-Chacon, Martin Stevens, Vivek Goyal
Passive hyperspectral long-wave infrared measurements are remarkably informative about the surroundings, such as remote object material composition, temperature, and range; and air temperature and gas concentrations. Remote object material and temperature

The Influence of Reorientational and Vibrational Dynamics on the Mg2+ Conductivity in Mg(BH4)2:CH3NH2

October 8, 2024
Author(s)
Mads Amdisen, Yongqiang Cheng, Niina Jalarvo, Daniel Pajerowski, Craig Brown, Torben R. Jensen, Mikael S. Andersson
Reorientational dynamics in solid electrolytes can significantly enhance the ionic conductivity, and understanding these dynamics can facilitate the rational design of improved solid electrolytes. Additionally, recent investigations on metal hydridoborate

Air-Stable Cu(I) Metal-Organic Framework for Hydrogen Storage

Debabrata Sengupta, Patrick Melix, Saptasree Bose, Joshua Duncan, Xingjie Wang, Mohammad Mian, Kent Kirlikovali, Faramarz Joodaki, Timur Islamoglu, Taner N. Yildirim, Randall Snurr, Omar Farha
Metal−organic frameworks (MOFs) that contain open metal sites have the potential for storing hydrogen (H2) at ambient temperatures. In particular, Cu(I)-based MOFs demonstrate very high isosteric heats of adsorption for hydrogen relative to other reported

High-Throughput Nanopore Fabrication and Classification Using Xe-Ion Irradiation and Automated Pore-Edge Analysis

September 26, 2022

Nicholas Derimow, Alejandro Romero, Aldo Rubio, Cesar Terrazas, Newell Moser, Orion Kafka, Jake Benzing, Francisco Medina, Ryan Wicker, Nik Hrabe
In this work, rectangular blocks of electron beam powder-bed fusion (PBF-EB) additively manufactured (AM) Ti-6Al-4V were built, such that a total of 68 mini-tensile test coupons could be extracted for mechanical testing over a range of build height and

Stable Nitride Precipitation in Additively Manufactured Nickel Superalloys

April 6, 2022
Author(s)
James Zuback, Fan Zhang, Andrew Iams, Lucille Giannuzzi, Todd Palmer
With negligible quantities of nitrogen, wrought and welded solid solution strengthened nickel superalloys usually contain carbides and topologically close-packed phases, such as Laves phase. However, appreciable nitrogen levels on the order of 0.1 mass %

Justin Whiting, Edward Garboczi, Vipin Tondare, John Henry J. Scott, Alkan Donmez, Shawn P. Moylan
The particle size distribution (PSD) and particlemorphology ofmetal powders undoubtedly affects the quality of parts produced by additivemanufacturing (AM). It is, therefore, crucial to accurately knowthe PSD and morphology of these powders. There exist

Amino Acid Exchangeability from Experimental Data

October 12, 2021
Author(s)
L Y. Yampolsky, Arlin Stoltzfus
Amino acid sequence differences between proteins are often interpreted by reference to a pairwise measure of amino acid similarity, based either on observed evolutionary transition probabilities, or on some physicochemical model of effects. However
