Density-operator theory of orbital magnetic susceptibility in periodic insulators
(2011-08)The theoretical treatment of homogeneous static magnetic fields in periodic systems is challenging, as the corresponding vector potential breaks the translational invariance of the Hamiltonian. Based on density operators ... -
Designing glass with non-dispersive stress-optic response
(Elsevier, 2016-02-01)The dispersion of the stress-optic response of a series of barium and lead phosphate glasses is measured using an ellipsometric method. It is found that the barium glasses display consistently positive dispersion with ... -
Deuteration and Tautomeric Reactivity of the 1-Methyl Functionality of Free-base Dipyrrins
(Organic and Biomolecular Chemistry, 2017)Regioselective reactivity of the 1-methyl group of free-base dipyrrins is explored, including discussion of tautomerism to provide exocyclic alkenyl reactivity. Deuterium is installed such as to generate dipyrrins substituted ... -

Electrochemical Activity of Nano-NiSi2 in Li Cells
(The Electrochemical Society, 2016-09-09)Crystalline and nanocrystalline NiSi2 were studied as negative electrode materials in Li cells. Crystalline NiSi2 was found to be inactive toward lithiation/delithiation. However, it was found that NiSi2 becomes active ... -
The Electrochemical Behavior of Polyimide Binders in Li and Na Cells
(The Electrochemical Society, 2015-12-09)The electrochemistry of aromatic and aliphatic polyimide binders was characterized in composite coatings for Li-ion and Na-ion battery negative electrodes. Aromatic polyimide was found to have a large first lithiation ... -
The Electrochemical Reaction Mechanism of Tin Phosphide with Sodium
(The Electrochemical Society, 2016-04-08)The sodiation mechanism of Sn4P3 was studied by ex-situ X-ray diffraction and Mössbauer effect spectroscopy. These results show that Sn4P3 is initially amorphized during sodiation, and suggest that upon further sodiation ... -
