Charge Carrier Dynamics and Mobility Determined by Time-Resolved Terahertz Spectroscopy on Films of Nano-to-Micrometer-Sized Colloidal Tin(II) Monosulfide

August 1, 2016
Author(s)
Brian Alberding, Adam Biacchi, Angela R. Hight Walker, Edwin J. Heilweil
Tin(II) monosulfide (SnS) is a semiconductor material with an intermediate band gap, high absorption coefficient is the visible range, and consists of earth abundant, non-toxic elements. For these reasons, SnS has generated much interest for incorporation

New Technologies and Standards Enabling Grid Modernization

August 1, 2016
Author(s)
David A. Wollman, Clark Gellings
"The smart grid, or grid modernization, integrates new interoperable and secure sensing,control, communications, information technologies and power technologies to increase the system efficiency, reliability, resilience, and sustainability of our electric

Transient Optical and Terahertz Spectroscopy of Nanoscale RuO2

August 1, 2016
Author(s)
Edwin J. Heilweil, Brian G. Alberding, Paul D. Cunningham, Joseph S. Melinger, Jeffrey C. Owrutsky, Adam D. Dunkelberger
Solution-deposited nanoscale films of RuO2, “nanoskins,” are effective transparent conductors because after calcining to 523 K they exhibit flat optical extinction across the visible and infrared combined with relatively high electrical conductivity. Upon

FREE-STANDING SELF-ASSEMBLIES OF GALLIUM NITRIDE NANOPARTICLES: A REVIEW

July 19, 2016
Author(s)
Winnie K. Wong-Ng, Yucheng Lan, Jianye Li, Rola M. Derbeshi, Abdellah Lisfi
Gallium nitride (GaN) is an III-V semiconductor with a direct band-gap of 3.4 eV. GaN has important potentials in white light-emitting diodes, blue lasers, and field effect transistors because of its super thermal stability and excellent optical properties

Thermoelectric properties of monolayer armchair MoS2 nanoribbons

June 16, 2016
Author(s)
Abbas Arab, Albert Davydov, Dimitrios A. Papaconstantopoulos, Qiliang Li
First-principle calculations have been performed to study thermoelectric properties of monolayer armchair nanoribbons. Structures have been relaxed to minimize force and stress before any calculation. Density functional theory using non-equilibrium Green’s

Preface (Semiconductor Materials for Solar Photovoltaic Cells)

May 18, 2016
Author(s)
Winnie Wong-Ng, Mariappan Paranthaman, Raghu Bhattacharya
This introductory chapter briefly describes the book "Semiconductor Materials for Solar Photovoltaic Cells", coedited by M. Parans Paranthaman, Winnie Wong-Ng, and Raghu N. Bhattacharya (Springer US, 2015). This essential reference provides the most

Optical Spintronics in Organic-Inorganic Perovskites Photovoltaics

April 25, 2016
Author(s)
Junwen Li, Paul M. Haney
Organic-inorganic halide CH 3NH 3PbI 3 solar cells have attracted enormous attention in recent years due to their remarkable power conversion efficiency. These materials should exhibit interesting spin-dependent properties as well, owing to the strong spin

Flame Retardant Emissions from Spray Polyurethane Foam Insulation

April 20, 2016
Author(s)
Dustin G. Poppendieck, Adam P. Blickley, Matthew Schlegel, Angelica Connor
The desire to build more energy efficient homes in the United States has led to the expansion of the residential spray polyurethane foam (SPF) insulation industry. Upon application of SPF, reacting chemicals form expanding polyurethane foam that fills

Validation and Verification of Automated Road Vehicles

April 2, 2016
Author(s)
Edward Griffor, Agaram Venkatesh, Frank Barickman, Felix Felix Fahrenkrog
Ubiquitous, commercial deployment of automated road vehicles is desirable in order to realize their potential benefits such as crash avoidance, congestion mitigation, reduced environment impact, reduced driver stress, and increased driver productivity. A

Predicting Structures of Ru-Centered Dyes: A Computational Screening Tool

March 16, 2016
Author(s)
Lisa A. Fredin, Thomas C. Allison
Dye-sensitized solar cells (DSCs) represent a viable means for harvesting solar energy to produce electrical power. Though a number of light harvesting dyes are in use, the search continues for more efficient and effective compounds to make commercially

Through-the-Glass Spectroscopic Ellipsometry for Analysis of CdTe Thin-Film Solar Cells in the Superstrate Configuration

February 25, 2016
Author(s)
Prakash Koirala, Jian Li, Heayoung Yoon, Puruswottam Aryal, Sylvain Marsillac, Angus R. Rockett, Nikolas Podraza, Robert W. Collins
Polycrystalline CdS/CdTe thin-film solar cells in the superstrate configuration have been studied by spectroscopic ellipsometry (SE) using glass side illumination. In this measurement method, the first reflection from the ambient/glass interface is

Improved thermoelectric performance of (Fe,Co)Sb3-type skutterudites from first-principles

February 3, 2016
Author(s)
Winnie K. Wong-Ng, Izaak Williamson, Logan J. Her, Xianli Su, Yonggao Yan, Lan Li
Skutterudite materials have been considered as promising thermoelectric candidates due to intrinsically good electrical conductivity and tailorable thermal conductivity. Options for improving thermal-to-electrical conversion efficiency include identifying

Density measurements of compressed-liquid dimethyl ether + pentane mixtures

January 1, 2016
Author(s)
Stephanie L. Outcalt, Eric W. Lemmon
Compressed-liquid densities of three compositions of the binary mixture dimethyl ether (CAS No. 115-10-6) + pentane (CAS No. 109-66-0) have been measured with a vibrating U-tube densimeter. Measurements were made at temperatures from 270 K to 390 K with

New perspective on glycoside hydrolase binding to lignin from pretreated corn stover

December 18, 2015
Author(s)
John M. Yarbrough, Ashutosh Mittal, Elisabeth Mansfield, Larry Taylor, Sarah Hobdey, Deanne W. Sammond, Yannick J. Bomble, Michael F. Crowley, Stephen R. Decker, Michael E. Himmel, Todd B. Vinzant
Non-specific binding of cellulases to lignin has been implicated as a major factor in the loss of cellulase activity during biomass conversion to sugars. It is believed that this binding may strongly impact process economics through loss of enzyme
