Sarkar Anwar, William Vandenberghe, Gennadi Bersuker, Dmitry Veksler, Giovanni Verzellesi, Creighton Buie, Eric Vogel, Christopher Hinkle
High-mobility alternative channel materials to silicon are critical to the continued scaling of metal-oxidesemiconductor (MOS) devices. The analysis of capacitancevoltage (C-V) measurements on these new materials with highk gate dielectrics is a critical

Coulomb drag and counterflow Seebeck coefficient in bilayer-graphene double layers

July 21, 2017

Jiuning Hu, David B. Newell, Jifa Tian, Nikolai N. Klimov, Tailung Wu, Yong Chen
We have fabricated bilayer-graphene double layers separated by a thin (~20 nm) boron nitride layer and performed Coulomb drag and counterflow thermoelectric transport measurements. The measured Coulomb drag resistivity is nearly three orders smaller in

Crystallographic Studies of Ba12Nb8-xTaxCo4O36 (x=1,3,4,5,7)

July 21, 2017
Author(s)
Winnie K. Wong-Ng, Guangyao Liu, Igor Levin, Izaak Williamson, James A. Kaduk, Lan Li, Andres C. Hernandez
Crystal structures and X-ray reference powder diffraction patterns have been determined for the Ba12Nb8-xTaxCo4O36 (x = 1, 3, 4, 5, 7) series. Ba12Nb8-xTaxCo4O36 crystallize in the cubic perovskite structure with a space group Pm3m (No. 221) and the

Effect of Interlamellar Interactions on Shear Induced Multilamellar Vesicles Formation

July 21, 2017
Author(s)
Youhei Kawabata, Robert David Bradbury, S. Kugizaki, Kathleen Weigandt, Y. B. Melnichenko, K. Sadakane, N. L. Yamada, H. Endo, Michihiro Nagao, H. Seto
Shear-induced multilamellar vesicle (MLV) formation has been studied by means of small-angle neutron scattering (SANS) technique coupled with neutron spin echo (NSE) spectroscopy. A mass fraction of 10% of nonionic surfactant pentaethylene glycol dodecyl

Relative range error evaluation of terrestrial laser scanners using a plate, a sphere, and a novel dual-sphere-plate target

July 21, 2017
Author(s)
Balasubramanian Muralikrishnan, Prem K. Rachakonda, Vincent D. Lee, Katharine M. Shilling, Daniel S. Sawyer, Geraldine S. Cheok
Terrestrial laser scanners (TLS) are a class of 3D imaging systems that produce a 3D point cloud by measuring the range and two angles at different sampling locations. The ranging unit of a TLS realizes the SI unit of length. Relative range error is one

Successive Field-Induced Transitions in BiFeO 3 Around Room Temperature

July 21, 2017
Author(s)
Shiro Kawachi, Atsushi Miyake, Toshimitsu Ito, Sachith E. Dissanayake, Masaaki Matsuda, William D. Ratcliff, Yang Zhao, Shin Miyahara, Masashi Tokunaga
The Effects of high magnetic fields applied perpendicular to the spontaneous ferroelectric polarization on single crystals of BiFeO 3 were investigated through magnetization, magnetostriction, and neutron diffraction measurements. The magnetostriction

Transition and Alkali Metal Complex Ternary Amides for Ammonia Synthesis and Decomposition

July 21, 2017
Author(s)
Hujun Cao, Jianping Guo, Fei Chang, Claudio Pistidda, Wei Zhou, Xilun Zhang, Antonio Santoru, Hui Wu, Norbert Schell, Rainer Niewa, Ping Chen, Thomas Klassen, Martin Dornheim
A new complex ternary amide Rb 2[Mn(NHd2) 4], which simultaneously contains both transition and alkali metal catalytic sites, is developed. This is in line with the recently reported TM-LiH composite catalysts, which has been shown to effectively break the

Ultrahigh and Selective SO 2 Uptake in Inorganic Anion-Pillared Hybrid Porous Materials

July 21, 2017
Author(s)
Xili Cui, Qiwei Yang, Lifeng Yang, Rajamani Krishna, Zhiguo Zhang, Zongbi Bao, Hui Wu, Zongbi Ren, Wei Zhou, Banglin Chen, Huabin Xing
The efficient capture of SO 2 is of great significance in gas purification processes including the flue gas desulfurization (FGD) and natural gas purification, but the design of porous materials with high adsorption capacity and selectivity of SO 2 remains

Analysis, Comparison, and Assessment of Latent Fingerprint Preprocessing

July 20, 2017
Author(s)
Haiying Guan, Paul Y. Lee, Curtis L. Lamp, Andrew Dienstfrey, Mary Frances Theofanos, Brian Stanton, Matthew Schwarz
Latent fingerprints obtained from crime scenes are rarely immediately suitable for identification purposes. Instead, most latent fingerprint images must be preprocessed to enhance the fingerprint information held within the digital image, while suppressing

Autonomous Relocation Strategies for Cells on Wheels in Public Safety Networks

July 20, 2017
Author(s)
Kamran Sayrafian, Ladan Rabieekenari
Lack of network availability or limited access to communication services are among the challenges that public safety officials and first responders could face during disasters or emergency scenarios. Networking infrastructure can partially (or sometimes

Open-path dual-comb spectroscopy to an airborne retroreflector

Kevin C. Cossel, Eleanor M. Waxman, Fabrizio R. Giorgetta, Michael A. Cermak, Dan Hesselius, Shalom Ruben, William C. Swann, Gregory B. Rieker, Nathan R. Newbury
We demonstrate a new technique for spatial mapping of multiple atmospheric gas species. This system is based on high-precision dual-comb spectroscopy to a retroreflector mounted on a flying multicopter. We measure the atmospheric absorption over long open

Smart Sensors and Standard-based Interoperability in Smart Grids
