Unraveling the Stable Cathode Electrolyte Interface in all Solid-State Thin-Film Battery Operating at 5 V

July 4, 2022
Author(s)
Ryosuke Shimizu, Diyi Cheng, Jamie Weaver, Minghao Zhang, Bingyu Lu, Thomas Wynn, Randall Burger, Min-cheol Kim, Guomin Zhu, Ying Shirley Meng
Spinel-type LiNi0.5Mn1.5O4 (LNMO) is one of the most promising 5 V-class cathode materials for Li-ion batteries that can achieve high energy density and low production costs. However, in liquid electrolyte cells, the high voltage causes continuous cell

Results from neutron imaging phase change experiments with LH2 and LCH4

Yuki Watanabe, Kim Hyeon-Deuk, Takafumi Yamamoto, Masayoshi Yabuuchi, Olesia M. Karakulina, Yasuto Noda, Takuya Kurihara, I-Ya Chang, Masanobu Higashi, Osamu Tomita, Cedric Tassel, Daichi Kato, Jingxin Xia, Tatsuhiko Goto, Craig Brown, Yuto Shimoyama, Naoki Ogiwara, Joke Hadermann, Artem M. Abakumov, Sayaka Uchida, Ryu Abe, Hiroshi Kageyama
The success and continued expansion of research in polyoxometalates (POMs) owe largely to their structural richness and wide range of functions. However, while most POM clusters known to date are negatively charged, there is only a handful of cationic POMs

Fabrication of black body grids by thick film printing for quantitative neutron imaging

June 8, 2022
Author(s)
Martin Wissink, Kirk Goldenberger, Luke Ferguson, Yuxuan Zhang, Hassina Bilheux, Jacob LaManna, David Jacobson, Michael Kass, Charles Finney, Jonathan Willocks
Neutron imaging offers deep penetration through many high-Z materials while also having high sensitivity to certain low-Z isotopes such as 1H, 6Li, and 10B. This unique combination of properties has made neutron imaging an attractive tool for a wide range

Probing the Link between Pancratistatin and Mitochondrial Apoptosis through Changes in the Membrane Dynamics on the Nanoscale

June 6, 2022
Author(s)
Stuart R. Castillo, Brett W. Rickeard, Mitchell DiPasquale, Michael H. Nguyen, Aislyn Lewis-Laurent, Milka Doktorova, Batuhan Kav, Markus S. Miettinen, Michihiro Nagao, Elizabeth Kelley, Drew Marquardt
Pancratistatin (PST) is a natural antiviral alkaloid that has demonstrated specificity towards cancerous cells and explicitly targets the mitochondria. PST initiates apoptosis while leaving healthy, noncancerous cells unscathed. However, the manner by

Phase retrieval based on deep learning in grating interferometer

April 25, 2022
Author(s)
Ohsung Oh, Youngju Kim, Daeseung Kim, Daniel Hussey, Seung Wook Lee
Grating interferometry is a promising technique to obtain differential phase contrast images with illumination source of low intrinsic transverse coherence. However, retrieving the phase contrast image from the differential phase contrast image is

Structures and Dynamics of Anionic Lipoprotein Nanodiscs

April 21, 2022
Author(s)
D. Sweeney, Susan T. Krueger, Kakali Sen, John Hackett
Nanolipoprotein particles known as nanodiscs (NDs) have emerged as versatile and powerful tools for the stabilization of mem-brane proteins permitting a plethora of structural and biophysical studies. Part of their allure is their flexibility to

Q-Dependent Collective Relaxation Dynamics of Glass-Forming Liquid Ca 0.4 K 0.6 (NO 3 ) 1.4 Investigated by Wide-Angle Neutron Spin-Echo

April 19, 2022

Peng Luo, Yanqin Zhai, Peter Falus, Victoria Garcia Sakai, Monika Hartl, Maiko Kofu, Kenji Nakajima, Antonio Faraone, Y. Z
Employing high-intensity wide-angle neutron spin-echo spectroscopy, we measured the coherent intermediate scattering function of the prototypical ionic glass former Ca 0.4K 0.6(NO 3) 1.4 in the equilibrium and supercooled liquid state from 383 to 519 K

Transformation of Lipid Vesicles into Micelles by Adding Nonionic Surfactants: Elucidating the Structural Pathway and the Intermediate Structures
