1. High-Resolution Photocurrent Microscopy Using Near-Field Cathodoluminescence of Quantum Dots
Topic: Energy Conversion, Storage, and Transport
Published: 6/10/2013
Authors: Heayoung Yoon, Youngmin Lee, Christopher Bohn, Seung Hyeon Ko, Anthony G Gianfrancesco, Jonathan S. Steckel, Seth Coe-Sullivan, Albert A. Talin, Nikolai B Zhitenev
Abstract: We report a fast, versatile photocurrent imaging technique to visualize the local photo response of solar energy devices and optoelectronics using near-field cathodoluminescence (CL) from a homogeneous quantum dot layer. This approach is quantitative ...

2. Computational Seebeck Coefficient Measurement Simulations
Series: Journal of Research (NIST JRES)
Report Number: 117.009
Topic: Energy Conversion, Storage, and Transport
Published: 5/2/2012
Author: Joshua Brooks Martin
Abstract: We have employed finite element analysis to develop computational Seebeck coefficient metrology simulations. This approach enables a unique exploration of multiple probe arrangements and measurement techniques within the same temporal domain. T ...

3. Direct Observation of Hydrogen Spillover in Ni-Loaded Pr-Doped Ceria
Topic: Energy Conversion, Storage, and Transport
Published: 1/17/2012
Authors: Vaneet Sharma, Peter A. Crozier, Renu Sharma, James B. Adams
Abstract: Hydrogen-spillover in Ni-loaded Pr-doped ceria (PDC) was directly observed using an environmental transmission electron microscope (ETEM). Localized reduction of ceria in a H2 atmosphere was observed and attributed to gas-Ni-ceria interactions at the ...

4. Electrolyte stability determines scaling limits for solid-state 3D Li-ion batteries
Topic: Energy Conversion, Storage, and Transport
Published: 12/20/2011
Authors: Dmitry Alexandrovich Ruzmetov, Vladimir Pavlovich Oleshko, Paul M Haney, Henri J Lezec, K Karki, K Baloch, Amit K Agrawal, Albert Davydov, Sergiy Krylyuk, Y Liu, JY Huang, Mihaela Tanase, John Cumings, Albert A. Talin
Abstract: Rechargeable, all-solid state Li-ion batteries (LIBs) with high specific capacity and small footprint are highly desirable to power an emerging class of miniature, autonomous microsystems that operate without a hardwire for power or communications. A ...

6. Improved activation and hydrogen storage properties of an amorphous Mg85Ni15 melt-spun alloy via surface treatment with NH4+ solution
Topic: Energy Conversion, Storage, and Transport
Published: 10/13/2011
Author: Eric Lass
Abstract: An amorphous Mg85Ni15 melt-spun hydrogen storage alloy, processed by submersion in an aqueous solution of NH4+, is able to absorb >5 wt. % hydrogen at 473 K during the first hydrogenation cycle. The nanocrystalline microstructure formed during devit ...

7. Compressed-Liquid Density Measurements of Methyl Oleate and Methyl Linoleate
Topic: Energy Conversion, Storage, and Transport
Published: 9/30/2011
Author: Stephanie L Outcalt
Abstract: Compressed liquid densities of the fatty acid methyl esters methyl linoleate and methyl oleate have been measured with a vibrating-tube densimeter. The temperature and pressure range of the measured data is from 270 K to 470 K, and 0.5 MPa to 50 MPa. ...

10. Neutron Depth Profiling Technique for Studying Aging in Li-ion Batteries
Topic: Energy Conversion, Storage, and Transport
Published: 2/15/2011
Author: Robert G Downing
Abstract: During operation of a Li-ion cell, lithium diffuses in and out of the solid phase anode and cathode. Measuring the lithium transport within the cell over its operational life could provide key information for understanding the loss of active lithiu ...
