1. Substitutional Doping in Nanocrystal Superlattices
Published: 8/27/2015
Authors: Aaron C Johnston-Peck, Matteo Cargnello, Benjamin T. Diroll, Eric Wong, Bianca Datta, Divij Damodar, Vicky V. T. Doan-Nguyen, Andrew A Herzing, Cherie R. Kagan, Christopher B. Murray

2. Microscopic investigation of Single-Wall Carbon Nanotube Uptake by Daphnia magna
Published: 12/18/2013
Authors: Aaron Edgington, Elijah J Petersen, Andrew A Herzing, Apparao Rao, Stephen Klaine
Abstract: The objectives of this study were to determine the absorption of single-wall carbon nanotubes (SWCNTs) across the gut epithelial cells in Daphnia magna and to determine if absorption was influenced by their surface functionalization. This project ut ...

3. Visualization of phase evolution in model organic photovoltaic structures via energy-filtered transmission electron microscopy
Published: 8/9/2013
Authors: Andrew A Herzing, Hyun Wook Ro, Christopher L Soles, Dean M DeLongchamp
Abstract: The morphology of the active layer in an organic photovoltaic bulk-heterojunction device is controlled by the extent and nature of phase separation during processing. Herein, we have examined the effects of fullerene crystallinity in the most wi ...

4. Robust Elemental Mapping of Nanostructures at Ultrahigh Resolution using Event-Streamed Spectrum Imaging in an Aberration-Corrected Analytical Electron Microscope
Published: 4/1/2013
Authors: Andrew A Herzing, Ian M. Anderson
Abstract: We detail the application of X-ray energy dispersive spectroscopy (XEDS) event-streamed spectral imaging (ESSI) in an aberration-corrected analytical electron microscope (AEM) as a reliable method for the acquisition of ultra-high spatial resolution ...

5. Size-Dependent Structural Distortions
Published: 1/7/2013
Authors: Michael D. Anderson, Colby L. Heideman, Qiyin Lin, Mary Smeller, Robert S. Kokenyesi, Andrew A Herzing, Ian M. Anderson, Douglas A. Keszler, Paul Zschack, David C. Johnson
Abstract: Recently we reported that intergrowth compounds [(MSe)1+y]m(TSe2)n, with M = {Pb, Bi Ce} and T = {W, Nb, Ta} self assemble from designed precursors. The values of m and n represent, respectively, the number of MSe and TSe2 structural units of the uni ...

6. Effect of Tin Doping on alpha-Fe2O3 Photoanodes for Water Splitting
Published: 6/28/2012
Authors: Christopher Bohn, Amit Kumar Agrawal, Erich C. Walter, Mark D Vaudin, Andrew A Herzing, Paul M Haney, Albert A. Talin, Veronika A Szalai
Abstract: Sputtered-deposited films of α-Fe2O3 of thickness 600 nm were investigated as photoanodes for solar water splitting and found to have photocurrents as high as 0.8 mA/cm2 at 1.23 V vs. the reversible hydrogen electrode (RHE). The incorporati ...

7. Nanoscale structure measurements for polymer-fullerene photovoltaics
Published: 2/3/2012
Authors: Dean M DeLongchamp, Regis J Kline, Andrew A Herzing
Abstract: This review covers methods to measure key aspects of nanoscale structure in organic photovoltaic devices based on polymer-fullerene bulk heterojunctions. The importance of nanoscale structure to the power conversion efficiency and stability of these ...

8. Imaging and Micronaylsis of Supported Metal Catalysts in the Analytical Electron Microscope
Published: 12/1/2011
Authors: Christopher J. Kiely, Andrew A Herzing
Abstract: The modern analytical electron microscope (AEM) is a powerful and versatile tool for the characterization of supported metal catalysts. The combination of atomic resolution images with chemical sensitivity at comparable length scales via X-ray energ ...

9. Molecular Order in High-Efficiency Polymer/Fullerene Bulk Heterojunction Solar Cells
Published: 9/22/2011
Authors: Matthew R. Hammond, Regis J Kline, Andrew A Herzing, Lee J Richter, David Germack, Hyun Wook Ro, Christopher L Soles, Daniel A Fischer, Tao Xu, Luping Yu, Michael F. Toney, Dean M DeLongchamp
Abstract: We report quantitative measurements of ordering, molecular orientation, and nanoscale morphology in the active layer of bulk heterojunction organic photovoltaic cells based on a thieno[3,4-b]thiophene-alt-benzodithiophene copolymer (PTB7), which has ...

10. Selective Oxidation of Glycerol by Highly Active Bimetallic Catalysts at Ambient Temperature under Base Free Conditions
Published: 8/24/2011
Authors: Andrew A Herzing, Gemma L. Brett, Peter Miedziak, Nikolaos Dimitratos, Meenakshisundaram Sankar, Marco Conte, Jose Antonio Lopez-Sanchez, David W Knight, Stuart H Taylor, Graham J Hutchings, Qian He, Christopher J Kiely
Abstract: AuPt or AuPd nanoparticles when supported on Mg(OH)2 are highly active for the selective oxidation of glycerol under base-free conditions at ambient temperatures. When bimetallic particles with the appropriate composition are prepared, catalysts wit ...
