Regulators, policy makers, and consumers are interested in proactively identifying services with acceptable or compliant data use policies, privacy policies, and terms of service. Academic requirements engineering researchers and legal scholars have

Solar Cell Performance Measurements Under Artificial Lighting Sources

January 5, 2021
Author(s)
Behrang Hamadani
In recent years, there has been a growing interest in measurements of photovoltaic solar cells under ambient artificial lighting such as light emitting diode (LED) or fluorescent light sources. Certain classes of solar cells are considered very good

Coherent optical processes with an all-optical atomic simulator

January 4, 2021
Author(s)
Ivan Burenkov, Sergey Polyakov, Olga Tikhonova, Irina Novikova
We show how novel photonic devices such as broadband quantum memory and efficient quantum frequency transduction can be implemented using three-wave mixing processes in a 1D array of nonlinear waveguides evanescently coupled to nearest neighbors. We do

January 4, 2021
Author(s)
Allison Domhoff, Tyler Martin, Liyanage M. Silva, Mansour Saberi, Stephen Creager, Eric Davis
Perfluorosulfonic acid (PFSA) ionomers are ubiquitous as proton-exchange membranes (PEMs) in vanadium redox flow batteries (VRFBs), as they provide high proton conductivity and robust chemical stability. However, traditional PFSA ionomers suffer from high

Quantifying Uncertainties in Solvation Procedures for Modeling Aqueous Phase Reaction Mechanisms

January 4, 2021
Author(s)
Kathleen Schwarz, Alex Maldonado, Tae Hoon Choi, Frank Eckert, Satoshi Hagiwara, Minoru Otani, Ravishankar Sundararaman, John Keith
Computational quantum chemistry provides fundamental chemical and physical insights into solvated reaction mechanisms across many areas of chemistry, especially in homogeneous and heterogeneous renewable energy catalysis. Such reactions may depend on

Structural Characterization and Modeling of a Respiratory Syncytial Virus Fusion Glycoprotein Nanoparticle Vaccine in Solution

January 4, 2021
Author(s)
Susan T. Krueger, Joseph E. Curtis, Daniel R. Scott, Alexander Grishaev, Greg Glenn, Gale Smith, Larry Ellingsworth, Oleg Borisov, Ernest Maynard
Globally, respiratory syncytial virus (RSV)is a major cause of sever lower respiratory tract infection in young children, older adults, and immune compromised populations, for which there are no licensed vaccines. The RSV fusion (F)/polysorbate 80 (PS80)

Biomonitoring of emerging DINCH metabolites in pregnant women in Charleston, SC: 2011-2014

January 1, 2021
Author(s)
Abby G. Wenzel, Jessica L. Reiner, Satomi Kohno, Bethany J. Wolf, John W. Brock, Lori Cruze, Roger B. Newman
Due to the mounting evidence that phthalates produce adverse endocrine effects in humans and wildlife, the use of other chemicals as replacements has increased. One of the most commonly encountered phthalate replacement is di(isononyl)cyclohexane-1,2

Complete collision data set for electrons scattering on molecular hydrogen and itsisotopologues: I. Fully vibrationally-resolved electronic excitation of H 2 (X 1 ? g + ).

January 1, 2021
Author(s)
Liam H. Scarlett, D Fursa, Mark C. Zammit, I Bray, Yuri Ralchenko, Kayla D. Davie
We present a comprehensive set of vibrationally-resolved cross sections for electron-impact electronic excitation of molecular hydrogen suitable for implementation in collisional-radiative models. The adiabatic-nuclei molecular convergent close-coupling

Complex by Design: Hydrotrope-Induced Micellar Growth in Deep Eutectic Solvents

January 1, 2021
Author(s)
Adrian Sanchez-Fernandez, Anna E. Leung, Elizabeth Kelley, Andrew J. Jackson
Here the microstructure of hydrotrope-surfactant assemblies in 1:2 choline chloride:glycerol (ChCl:Glyc) is presented. The effect of choline salicylate (ChSal) on the micellization of hexadecyltrimethylammonium chloride (C 16TAC) was investigated by

In situ characterization of ceramic cold sintering by small-angle scattering

January 1, 2021
Author(s)
Andrew Allen, Igor Levin, Russell Maier, Suzanne E. Witt, Fan Zhang, Ivan Kuzmenko
The first in situ characterization of the pore morphology evolution during the cold sintering process (CSP) is presented using small-angle X-ray scattering methods. For practical reasons, measurements have been made on a model system, KH2PO4 (KDP). The
