Control of Micro-and Nanostructure of Layered Double Hydroxides by Hydrothermal Treatment

February 23, 2023
Author(s)
Keiichiro Maegawa, Fan Zhang, Qiaxian Johnson, Mihaela Jitianu, Tan Wai Kian, Go Kawamura, Atsunori Matsuda, Andrei Jitianu
Layered double hydroxides (LDHs) are mixed M(II) and M(III) hydroxides with positively charged lamellar brucite layers and interlayered anions. LDHs attracted significant attention due to their anion and cation-exchange ability, adsorption capacity, and

Unified graph neural network force-field for the periodic table: solid state applications

February 23, 2023
Author(s)
Kamal Choudhary, Brian DeCost, Lily Major, Keith Butler, Jeyan Thiyagalingam, Francesca Tavazza
Classical force fields (FFs) based on machine learning (ML) methods show great potential for large scale simulations of solids. MLFFs have hitherto largely been designed and fitted for specific systems and are not usually transferable to chemistries beyond

Solvent Transport Model for Polyamide Nanofilm Membranes Based on Accurate Hansen Solubility Parameters

February 21, 2023
Author(s)
Min Gyu Shin, Wansuk Choi, June Huh, William Mulhearn, Jung Sun Hwang, Christopher Stafford, Jeong F Kim, Jung Hyun Lee
Polyamide (PA) nanofilm membranes for solvent filtration are widely used in various industries. However, reliable models that can describe solvent transport in PA membranes have yet to be developed owing to measurement challenges associated with the highly

Thermal and Electronic Properties of Ba2MnSe3

February 15, 2023
Author(s)
Adam Biacchi, Oluwagbemiga Ojo, Wilarachchige Gunatilleke, George Nolas
The structural, thermal, and electronic properties of Ba2MnSe3 were investigated. Analysis of the low-temperature heat capacity revealed a low Debye temperature and a low average speed of sound that, together with the bonding in this material, result in a

Nondestructive quantification of single crystal elasticity for additively manufactured SB-CoNi-10C, IN625, and Ti64

February 2, 2023
Author(s)
Jeff Rossin, Patrick Leser, Jake Benzing, Chris Torbet, Peter Dillon, Stephen Smith, Samantha Daly, Tresa Pollock
Resonant ultrasound spectroscopy (RUS) is capable of determining the single crystal elastic constants from polycrystalline specimens with known crystallographic texture. However, the calculated single crystal elastic constants vary with the measured

A Non-Intrusive Fluorescent Pattern for Internal Microscale Strain Measurements Using Digital Image Correlation

February 1, 2023
Author(s)
Ami Ahure Powell, William Mulhearn, Shawn Chen, Stephan J. Stranick, Jeffrey Gilman, Mark Iadicola, Jeremiah Woodcock
A non-intrusive and non-disruptive internal fluorescent pattern is designed, developed, and tested using digital image correlation (DIC), an effective non-contact optical method, to measure deformation at internal planes of a polymer matrix material. The

Dynamic structural and microstructural responses of a metal organic framework type material to carbon dioxide under dual gas flow and supercritical conditions

February 1, 2023
Author(s)
Andrew J. Allen, Eric J. Cockayne, Winnie Wong-Ng, Jeffrey Culp, Ivan Kuzmenko
The structural and microstructural responses of a model metal-organic framework (MOF) material, Ni(3-Methy-4,4'-bipyridine)[Ni(CN)4] (Ni-BpyMe or PICNIC 21), to CO2 adsorption and desorption are reported for in situ small-angle X-ray scattering (SAXS) and

Facile Polymerization in a Bicellar Template to Produce Polymer Nano-Rings

January 15, 2023
Author(s)
Chung-Hao Liu, Catherine Cheu, John Barker, Lin Yang, Mu-Ping Nieh
Hypothesis: A well-defined discoidal bicelle composed of three lipids, specifically zwitterionic long-chain 1,2-dipalmitoyl phosphocholine (DPPC) and short-chain 1,2-dihexanoyl phosphocholine (DHPC) doped with anionic 1,2-dipalmitoyl phosphoglycerol (DPPG)

3D Asymmetric Bilayer Garnet-Hybridized High-Energy-Density Lithium-Sulfur Batteries

January 11, 2023
Author(s)
Changmin Shi, Tanner Hamann, Saya Takeuchi, George Alexander, Adelaide M. Nolan, Matthew Limpert, Zhezhen Fu, Jonathan O'Neill, Griffin Godbey, Joseph A. Dura, Eric Wachsman
Lithium garnet Li 7La 3Zr 2O 12 (LLZO) with high ionic conductivity and chemical stability against a Li metal anode is considered one of the most promising solid electrolytes for lithium-sulfur batteries. However, an infinite charge time resulting in low

Hydration of a side-chain-free n-type ladder semiconducting polymer driven by electrochemical doping

January 11, 2023
Author(s)
Jiajie Guo, Lucas Flagg, Duyen Tran, Shinya Chen, Ruipeng Li, Nagesh Kolhe, Rajiv Giridharagopal, Samson A. Jenekhe, Lee J. Richter, David Ginger
We study the organic electrochemical transistor (OECTs) performance of the ladder polymer, poly(benzimidazobenzophenanthroline) (BBL) in an attempt to better understand how an apparently insoluble side-chain free polymer is able to operate as an OECT with
