Synthesis, Structure, and Ion Conduction of Potassium Carbazolides for Potassium Ion Solid-State Electrolytes

September 20, 2024
Author(s)
Jiaquan Guo, Yang Yu, Khai Chen Tan, Qijun Pei, Zhao Li, Yuting Wang, Alexis Munyentwali, Hui Wu, Teng He, Ping Chen
Potassium ion batteries gradually have aroused worldwide interest due to the limited lithium resource. However, the research on the solid-state potassium-ion batteries is at its very early stage. The lack of electrolytes with high ionic conductivity and in

Crystallographic Polarity Measurements in Two-Terminal GaN Nanowire Devices by Lateral Piezoresponse Force Microscopy

July 23, 2020
Author(s)
Matthew Brubaker, Alexana Roshko, Samuel Berweger, Paul T. Blanchard, Todd E. Harvey, Norman A. Sanford, Kristine Bertness
Lateral piezoresponse force microscopy (L-PFM) is demonstrated as a reliable method for determining the crystallographic polarity of individual, dispersed GaN nanowires that were functional components in electrical test structures. In contrast to PFM

Milliwatt-threshold visible-telecom optical parametric oscillation using silicon nanophotonics

December 20, 2019
Author(s)
Xiyuan Lu, Gregory Moille, Anshuman Singh, Qing Li, Daron Westly, Ashutosh Rao, Su P. Yu, Travis Briles, Scott Papp, Kartik Srinivasan
The on-chip creation of coherent light at visible wavelengths is of interest to many applications in spectroscopy, sensing, and metrology. Towards that goal, here we propose and demonstrate the first on-chip visible-telecom optical parameteric oscillator

Reliability Issues of SiC MOSFETs: A Technology for High Temperature Environments

September 20, 2010
Author(s)
Liangchun (. Yu, Greg Dunne, Kevin Matocha, Kin P. Cheung, John S. Suehle, Kuang Sheng
The wide-bandgap nature of silicon carbide (SiC) makes it an excellent candidate for applications where high temperature is required. The MOS-controlled power devices are the most favorable structure, however, it is widely believed that silicon oxide on

… binding to AuNPs, the maximum surface density of TNF is (0.09 ± 0.02) nm-2 with a binding constant of 3×106 L/mol. …

Rapid Melting of Nb - 47 Mass % Ti: Effect of Heating Rate and Grain Size

September 8, 1999
Author(s)
William J. Boettinger, Daniel Josell, Sam R. Coriell, D Basak
The effect of heating rate and grain size on the melting behavior of Nb - 47 mass % Ti is measured. The experimental method uses rapid resistive self-heating of wire specimens at rates between 10(2 superscript) and 104 superscript) K/s and simultaneous

Effect of Heating Rate and Grain Size on the Melting Behavior of the Alloy Nb-47 Mass% Ti in Pulse-Heating Experiments

September 1, 1998
Author(s)
D Basak, William J. Boettinger, Daniel Josell, Sam R. Coriell, J L. McClure, Sitaraman Krishnan, A Cezairliyan
The effect of heating rate and grain size on the melting behavior of Nb-47 mass % Ti is measured and modeled. The experimental method uses rapid resistive self-heating of wire specimens at rates between -10 2 and -10 4 K/s and simultaneous measurement of

Unintended consequences: Assessing thermo-mechanical changes in vinyl nitrile foam due to micro-computed X-ray tomographic imaging

October 5, 2023
Author(s)
Alexander Landauer, Zois Tsinas, Orion Kafka, Newell Moser, Jack Leigh Glover, Aaron M. Forster
Micro-computed X-ray tomography (μCT) is a volumetric imaging tool used to quantify the internal structure of materials. μCT imaging with mechanical testing (in situ μCT) helps visualize strain-induced structural changes and develop structure-property

Toward improved quantum simulations and sensing with trapped two-dimensional ion crystals via parametric amplification

March 29, 2023
Author(s)
Matthew Affolter, Wenchao Ge, Bryce Bullock, Shaun Burd, Kevin Gilmore, Jennifer Lilieholm, Allison Carter, John J. Bollinger
Improving coherence is a fundamental challenge in quantum simulation and sensing experiments with trapped ions. Here we discuss, experimentally demonstrate, and estimate the potential impacts of two different protocols that enhance, through motional

Results from the Baksan Experiment on Sterile Transitions (BEST)

Sub-picoliter Traceability of Microdroplet Gravimetry and Microscopy

December 20, 2021
Author(s)
Lindsay C. C. Elliott, Adam L. Pintar, Craig R. Copeland, Thomas Brian Renegar, Ronald G. Dixson, Robert Ilic, R. Michael Verkouteren, Samuel M. Stavis
Volumetric analysis of single microdroplets is difficult to perform by ensemble gravimetry, whereas optical microscopy is often inaccurate beyond the resolution limit. To address the latter issue, we advance and integrate these complementary methods
