All-Temperature Zinc Batteries with High-Entropy Aqueous Electrolyte

January 9, 2023
Author(s)
Chongyin Yang, Jiale Xia, Chunyu Cui, Travis P. Pollard, Jenel Vatamanu, Antonio Faraone, Joseph Dura, Madhu Sudan N. Tyagi, Alex Kattan, Elijah Thimsen, Jijian Xu, Wentao Song, Enyuan Hu, Xiao Ji, Singyuk Hou, Xiyue Zhang, Michael S. Ding, Sooyeon Hwang, Dong Su, Yang Ren, Xiao-Qing Yang, Howard Wang, Oleg Borodin, Chunsheng Wang
Solvent-in-salt electrolytes have revolutionized both aqueous and non-aqueous batteries by extending the electrochemical stability window 1,2,3 and enabling new battery chemisties 4-6. However, the presence of both anions and solvent in the cation

Entropy Scaling of Viscosity for Molecular Models of Molten Salts

January 9, 2023
Author(s)
Jeffrey Young, Ian Bell, Allan H. Harvey
Entropy scaling relates dynamic and thermodynamic properties by reducing the viscosity to be a function of only the residual entropy. Molecular simulations are used to investigate the entropy scaling of the viscosity of three models of sodium chloride and

Nanoscale Bending Dynamics in Mixed-Chain Lipid Membranes

January 9, 2023
Author(s)
Elizabeth Kelley, Moritz Frewein, Orsolya Czakkel, Michihiro Nagao
Lipids that have two tails of different lengths are found throughout biomembranes in nature, yet the effects of this asymmetry on the membrane properties, are not well understood, especially when it comes to the membrane dynamics. Here we study the

Photonic Online Learning: A Perspective

January 9, 2023
Author(s)
Sonia Buckley, Alexander Tait, Adam McCaughan, Bhavin Shastri
Neuromorphic systems promise to solve certain problems faster and with higher energy efficiency than traditional computing, by using the physics of the devices themselves for information processing. While initial results in photonic neuromorphic hardware

Formalizing and Reasoning about Supply Chain Contracts between Agents

January 8, 2023
Author(s)
Dylan Flynn, Chasity Nadeau, Jeannine Shantz, Marcello Balduccini, Tran Son, Edward Griffor
Inspired by the recent problems in supply chains, we propose an approach to declarative modeling of contracts between agents that will eventually support reasoning about resilience of and about ways to improve supply chains. Specifically, we present a high

Does friction contribute to formability improvement using servo press?

January 6, 2023
Author(s)
Dilip K. Banerjee, Kali Prasad, Aishwary Gupta, Hariharan Krishnaswamy, Uday Chakkingal, Myoung-Gyu Lee
Servo press forming machines are advanced forming systems that are capable of imparting interrupted punch motion, resulting in enhanced room temperature formability. The exact mechanism of the formability improvement is not yet established. The

Interface formation and Schottky barrier height for Y, Nb, Au, and Pt on Ge as determined by hard x-ray photoelectron spectroscopy

January 6, 2023
Author(s)
Abdul Rumaiz, Ian Harding, Conan Weiland, Neha Nooman, Thomas Krings, Ethan Hull, Gabriele Giacomini, Wei Chen, Eric J. Cockayne, D. Peter Simmons, Joseph Woicik
Development of a robust, thin, hole-blocking (n+) contact on high purity germanium (HPGe) has been the main challenge in the development of Ge-based radiation sensors. Yttrium has been reported to be a viable hole-blocking contact on HPGe, and detectors

Orthogonal and complementary measurements of properties of drug products containing nanomaterials

January 6, 2023
Author(s)
Bryant C. Nelson, Elijah Petersen, Carl Simon Jr., Sven-Even Borgos, Luigi Calzolai, Jeremie Parot, Matthias Roesslein, Fanny Caputo, Xiaoming Xu
Quality control of pharmaceutical and biopharmaceutical products, and verification of their safety and efficacy, depends on reliable measurements of critical quality attributes (CQAs). The task becomes particularly challenging for drug products and

Value Assignment of Standard Reference Material(R) 1849b Infant/Adult Nutritional Formula I

January 6, 2023
Author(s)
Melissa M. Phillips, Laura Wood, Charles Barber, Bruce Scruggs, John Sieber, James H. Yen, Lee L. Yu
The National Institute of Standards and Technology (NIST) Standard Reference Material® (SRM®) 1849b Infant/Adult Nutritional Formula I delivers certified or non-certified values for over 100 analytes. This material is intended to be used for the evaluation

Microfabricated strontium atomic vapor cells

January 5, 2023
Author(s)
Jacob Pate, John Kitching, Matthew Hummon
We demonstrate strontium (Sr) atomic vapor cells having a total external volume of 0.63 cm3 that can operate above 300 °C for times exceeding 380 h. The cells are fabricated using micromachined silicon frames anodically bonded to glass windows that have a
