Yang Yu, Pinar Karayaylali, Stanislaw Nowak, Livia Giordano, Magali Gauthier, Wesley Hong, Ronghui Kuo, John Vinson, Dimosthenis Sokaras, Cheng-Jun Sun, Nenian Charles, Filippo Maglia, Roland Jung, Yang Shao-Horn
Anion redox in lithium transition metal oxides such as Li2RuO3 and Li2MnO3, has catalyzed intensive research efforts on the seek of first-row transition metal oxides that may boost up the energy density for lithium-ion batteries. The physical origin for

Low-Power Wide Area Networks (LPWAN) for Communications of Mobile Sensor Data

September 10, 2019
Author(s)
Sebastian Barillaro, Sokwoo Rhee, Raghu N. Kacker, Mark L. Badger, David R. Kuhn, Gustavo Escudero
There are multiple options for communication of data to and from mobile sensors. For tracking systems, Global Navigation Satellite System (GNSS) is often used for localization and mobile- phone technologies are used for transmission of data. Low-power wide

A Multi-Laboratory Investigation of Drug Background Levels

September 9, 2019
Author(s)
Edward R. Sisco, Marcela N. Najarro
Identifying, quantifying, and analyzing the drug background in operational environments such as forensic laboratories is an emerging body of research. Understanding these levels can provide critical information to address issues like occupational exposure

Crystal Orientation Drives the Interface Physics at 2/3-Dimensional Hybrid Perovskites

Lee J. Richter, Ahmad R. Kirmani, Marine E. Bouduban, Valentine I. Queloz, Valentina M. Caselli, Kyung T. Cho, Sanghyun Paek, Cristina Roldan-Carmona, Jacques E. Moser, Tom J. Savenije, Mohammad K. Nazeeruddin, Giulia Grancini
Combining halide perovskites with tailored dimensionality into two/three-dimensional (2D/3D) systems has revealed a powerful strategy to boost the performances of perovskite photovoltaics (PVs). Despite recent advances, a clear understanding of the

Pumping and decay rates of cold atoms dark states

September 9, 2019
Author(s)
Moshe Shuker, Juniper Pollock, V. I. Yudin, John Kitching, Elizabeth Donley
Coherent dark states in atoms, created by simultaneous interaction of two coherent light fields with an atom, are of prime importance in quantum state manipulation. They are used extensively in quantum sensing and quantum information applications to build

Tailoring Biomimetic Phosphorylcholine-Containing Block Copolymers as Membrane-Targeting Cellular Rescue Agents

September 9, 2019
