Multiphase Magnetism in Yb 2 Ti 2 O 7

November 3, 2020
Author(s)
Allen Scheie, Jonas Kindervater, Shu Zhang, Hitesh Changlani, G. Sala, Georg Ehlers, Andre Heinemann, Gregory Tucker, Seyed Koohpayeh, Collin L. Broholm

Materials Research & Measurement Needs for Ceramics Additive Manufacturing

November 1, 2020
Author(s)
Andrew J. Allen, Igor Levin, Suzanne E. Witt
We report on a recent workshop dedicated to additive manufacturing (AM) of ceramics that was held at the National Institute of Standards and Technology (NIST) in November 2019. This two- day all-invited meeting brought together experts from industry

Correlation of Nano-morphology with Structural and Spectroscopic Studies in Organic Solar Cells

October 27, 2020
Author(s)
Eliot Gann, Christopher McNeill, Wenchao Huang, Dinesh Kabra, Urvashi Bothra, Nakul Jain, Amelia C. Liu
The nano-morphology of bulk heterojunction blends based on poly[[4,8-bis[(2- ethylhexyl)oxy]benzo[1,2-b:4,5- b']dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]] (PTB7) blended with [6,6]- phenyl-C71-butyric acid methyl

Reduction of charge offset drift using plasma oxidized aluminum in SETs

October 26, 2020
Author(s)
Yanxue Hong, Ryan Stein, Michael Stewart, Neil M. Zimmerman, Joshua M. Pomeroy
Aluminum oxide (AlOx)-based single-electron transistors (SETs) fabricated in ultra-high vacuum (UHV) chambers using in situ plasma oxidation show excellent stabilities over more than a week, enabling applications as tunnel barriers, capacitor dielectrics

Semiconducting to Metallic Electronic Landscapes in Defects Controlled Two-Dimensional ?-d Conjugated Coordination Polymer Thin Films

October 16, 2020
Author(s)
Cherno Jaye, Daniel A. Fischer, Jonathan Ogle, Nabajit Lahiri, Christopher Tassone, Janis Louie, Luisa Whittaker-Brooks
Two-dimensional coordination polymers (2D CPs) are of significant interest due to their intriguing structural, optical, and electrical properties which can be tuned through the selective coordination of different metals and organic linkers. Although, 2D

Structural Properties of Kerogens with Different Maturities

October 15, 2020
Author(s)
Wei-Shan Chiang, Jin-hong Chen, David Jacobi, Taner N. Yildirim
The thermogenic transformation of kerogen into hydrocarbons accompanies the development of a pore network within the kerogen that serves as gas storage locations both in pore space and surface area for adsorbed gas within the source rock. Therefore, the

Dynamics of Hydroxyl Anions Promotes Lithium Ion Conduction in Antiperovskite Li 2 OHCl

October 13, 2020
Author(s)
Fei Wang, Hayden Evans, Kwangnam Kim, Liang Yin, Yiliang Li, Ping-Chun Tsai, Jue Liu, Saul H. Lapidus, Craig Brown, Donald J. Siegel, Yet-Ming Chiang
Li 2OHCl is an exemplar of the anti-perovskite family of ionic conductors, for which high ionic conductivities have been reported, but in which the atomic-level mechanism of ion migration is unclear. The stable phase is highly defective, having 1/3 of the

Position-Dependent Diffusion Dynamics of Entangled Polymer Melts Nanoconfined by Parallel Immiscible Polymer Films

October 9, 2020
Author(s)
Kyong-Il Jo, Yonghoon Oh, Tae-Ho Kim, Joona Bang, Guangcui Yuan, Sushil K. Satija, Bong J. Sung, Jaseung Koo
The morphological structure and dynamics of confined polymers adjacent to the polymer–polymer interface have a profound effect on determining the overall physical properties of polymer blends. We measured the diffusion dynamics of polymethylmethacrylate

Porous Organic Cages as Synthetic Water Channels

September 30, 2020
Author(s)
Yi D. Yuan, Jinqiao Dong, Jie Liu, Daohui Zhao, Hui Wu, Wei Zhou, Hui X. Gan, Yen W. Tong, Jianwen Jiang, Dan Zhao
Nature has protein channels (e.g., aquaporins) that preferentially transport water molecules while rejecting even the smallest hydrated ions. Aspirations to create robust synthetic counterparts have led to the development of a few one-dimensional (1D)

Pushing the Limits of Bottom-Up Gold Filling for X-Ray Grating Interferometry

September 30, 2020
Author(s)
Daniel Josell, Thomas P. Moffat, Z Shi, K Jefimovs, L Romano, J. Vila-Comamala
The application of superconformal Bi-catalyzed Au electrodeposition for void-free filling of recessed trenches in X-ray gratings used in phase contrast imaging is detailed. Filling of trenches with aspect ratio (height divided by its width) up to 55 is
