A Combinatorial Investigation of Fe-Si-Zn Thin Film Negative Electrodes for Li-ion 1 Batteries (Preprint)
(IOP Publishing, 2014-12-04)
Thin-film Fe-Si-Zn libraries were investigated as negative electrode materials for Li-ion batteries using combinatorial and high-throughput techniques. X-ray diffraction and electron microprobe measurements were used to ...
Mixed Transition Metal Titanate and Vanadate Negative Electrode Materials for Na-Ion Batteries (Preprint)
(IOP Publishing, 2014-11-07)
Sodium-ion batteries have the potential to be a low cost, sustainable replacement for lithium-ion batteries in large scale energy storage. The lack of practical negative electrode materials limit the development of Na-ion ...

Thin-film Fe-Zn libraries were investigated as negative electrode materials for Li-ion batteries using combinatorial and high-throughput techniques. X-ray diffraction, Mössbauer effect spectroscopy and electron microprobe ...
Mössbauer and Electrochemical Investigations of Carbon-Rich Fe1-xCx Films (Preprint)
(2015 Elsevier Ltd., 2015-07-10)
A thin film binary library of carbon-rich Fe1-xCx (0.47 ≤ x ≤ 0.97) alloys was prepared by combinatorial sputtering of carbon and iron. The sputtered library was characterized by X-ray diffraction and room temperature 57Fe ...
Investigation of the NaNixMn1-xO2 (0 ≤ x ≤ 1) System for Na-ion Battery Cathode Materials (Preprint)
(IOP Publishing, 2015-01-06)
Layered NaNixMn1-xO2 (0 ≤ x ≤ 1) oxides were prepared via solid state reactions. Different reaction conditions were required to obtain phase pure samples, depending on the value of x. The 0 ≤ x ≤ 0.1 compositions were ...
The Reversible Magnesiation of Pb (Preprint)
(Elsevier Ltd, 2015-03-04)
Sputtered Pb films have been found to reversibly alloy electrochemically with magnesium in Grignard based electrolytes. The voltage curve shows a single plateau at about 125 mV vs. Mg, corresponding to the formation of ...
Lab-scale chemical vapor deposition onto powders
(AIP Publishing, 2022-07-06)
In this paper, a laboratory chemical vapor deposition (CVD) reactor is described, which features an opposing screw rotating fluidized bed. The reactor efficiently concentrates powdered reactants in the reaction zone while ...
Quantitative Measurement of Compositional Inhomogeneity in NMC Cathodes by X-ray Diffraction Postprint
