Autor: Ran Gu, Yevgeny Rakita, Ling Lan, Zach Thatcher, Gabrielle E. Kamm, Daniel O’Nolan, Brennan Mcbride, Allison Wustrow, James R. Neilson, Karena W. Chapman, Qiang Du, Simon J. L. Billinge

Publikováno v: npj Computational Materials, Vol 10, Iss 1, Pp 1-15 (2024)

Abstract A novel algorithm, stretchedNMF, is introduced for non-negative matrix factorization (NMF), accounting for signal stretching along the independent variable’s axis. It addresses signal variability caused by stretching, proving beneficial fo

A stable cathode-solid electrolyte composite for high-voltage, long-cycle-life solid-state sodium-ion batteries

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-11 (2021)

Rechargeable solid-state sodium-ion batteries hold great promise for safer and more energy-dense energy storage. Here, the authors show a new sodium-based halide, Na3-xY1-xZrxCl6, for sodium-all-solid-state batteries with enhanced ionic conductivity

Synthetic Access to a Framework-Stabilized and Fully Sulfided Analogue of an Anderson Polyoxometalate that is Catalytically Competent for Reduction Reactions

Autor: Jiaxin Duan, Hafeera Shabbir, Zhihengyu Chen, Wentuan Bi, Qin Liu, Jingyi Sui, Luka Đorđević, Samuel I. Stupp, Karena W. Chapman, Alex B. F. Martinson, Alice Li, Richard D. Schaller, Subhadip Goswami, Rachel B. Getman, Joseph T. Hupp

Publikováno v: Journal of the American Chemical Society. 145:7268-7277

Polyoxometalates (POMs) featuring 7, 12, 18, or more, redox-accessible transition-metal ions are ubiquitous as selective catalysts, electrocatalysts, and sensitized photocatalysts, especially for oxidation reactions. The corresponding synthetic and c

Pair distribution function analysis of discrete nanomaterials in PDFgui

Autor: Zhihengyu Chen, Michelle L. Beauvais, Karena W. Chapman

Publikováno v: Journal of Applied Crystallography. 56:328-337

Pair distribution functions (PDFs) are a leading tool for atomic structure analysis of nanomaterials. However, the most widely used programs for refining atomic structure against PDF data are based on extended crystallographic models, which cannot be
