The interactive effect of heat and mass transport on water condensation in the gas diffusion layer of a proton exchange membrane fuel cell

December 31, 2020
Author(s)
Po-Ya A. Chuang, Md A. Rahman, Felipe Mojica, Daniel S. Hussey, David L. Jacobson, Jacob LaManna
Despite recent advancement in fuel cell technology, significant challenges remain in achieving high power density operation to meet the stringent targets of performance, durability and cost. This is due to the lack of fundamental understanding in

A system for probing Casimir energy corrections to the condensation energy

December 28, 2020
Author(s)
Diego J. Perez, Alexander Stange, Richard Lally, Lawrence Barrett, Matthias Imboden, Abhishek Som, David Campbell, Vladimir Aksyuk, David Bishop
In this article, we present a nano-electromechanical system (NEMS) designed to detect changes in the Casimir Energy. The Casimir effect is a result of the appearance of quantum fluctuations in the electromagnetic vacuum. Previous experiments have used nano

December 28, 2020
Author(s)
Mark A. Anders, Patrick M. Lenahan, Nicholas J. Harmon, Michael E. Flatte
We discuss a new technique to measure spin dependent trapping events at the MOSFET interface named near zero field spin dependent charge pumping (NZF SDCP) which is based on the powerful MOSFET interface trap characterization measurement called charge

Developing Single Layer MOS Quantum Dots for Diagnostic Qubits

December 28, 2020
Author(s)
Yanxue Hong, Aruna Ramanayaka, Ryan Stein, Joshua M. Pomeroy
The design, fabrication and characterization of single metal gate layer, metal-oxide- semiconductor (MOS) quantum dot devices robust against dielectric breakdown are presented as prototypes for future diagnostic qubits. These devices were developed as a

Author(s)
Qingbin Fan, Mingze Liu, Cheng Zhang, Wenqi Zhu, Yilin Wang, Peicheng Lin, Feng Yan, Lu Chen, Henri Lezec, Yanqing Lu, Amit Agrawal, Ting Xu
Exquisite polarization control using optical metasurfaces has attracted considerable attention thanks to their ability to manipulate multichannel independent wavefronts with subwavelength resolution. Here we present a new class of metasurface polarization

Confinement and Processing Can Alter the Morphology and Periodicity of Bottlebrush Block Copolymers in Thin Films

December 22, 2020
Author(s)
Daniel Sunday, Moshe Dolejsi, Alice B. Chang, Lee Richter, Ruipeng Li, Paul Nealey, Robert H. Grubbs
Bottlebrush block copolymers (BBCPs) are intriguing architectural variations on linear BCPs with highly tunable structure. Confinement can have a significant impact on polymer assembly, giving rise to changes in morphology, assembly kinetics, and properties

Microscopic Origin of Inhomogeneous Transport in Four-Terminal Tellurene Devices

December 22, 2020
Author(s)
Benjamin Kupp, Gang Qiu, Yixiu Wang, Clayton Caspeer, Thomas Mitchell (Mitch) Wallis, Joanna Atkin, Wenzhuo Wu, Peide Ye, Pavel Kabos, Samuel Berweger
Tellurene—the 2D form of elemental tellurium—provides an attractive alternative to conventional 2D semiconductors due to its high bipolar mobilities, facile solution processing, and the possibility of dopant intercalation into its 1D van der Waals lattice
