Sintered polymeric binders for Li-ion battery alloy anodes
(www.nrcresearchpress.com/cjc, 2018-11-28)The cycling performance in lithium half cells of Si alloy electrodes with polyvinylidene fluoride or polyimide binders were evaluated after the electrodes were cured at temperatures below and above the binder carbonization ... -
Sodium distribution in sodium tellurite glasses probed with spin-echo NMR
(1997-09)We present results on the spatial distribution of sodium cations in sodium tellurite glasses as a function of sodium oxide content, obtained using a spin-echo NMR experiment. Glasses were studied with sodium oxide content ... -

Spherically Smooth Cathode Particles by Mechanofusion Processing
(The Electrochemical Society, 2019-08-27)Surface modification has been shown to be useful for improving the cycling performance of cathode materials. Typically hetero-compositional coatings are applied on cathode particle surfaces using methods, such as aqueous ... -
Spin waves and quantum criticality in the frustrated XY pyrochlore antiferromagnet Er2Ti2O7
(2008-10)We report detailed measurements of the low temperature magnetic phase diagram of Er2Ti2O7. Heat capacity and time- of- flight neutron scattering studies of single crystals reveal unconventional low- energy states. Er3+ ... -
Stabilizing NaCrO2 by Sodium Site Doping with Calcium
(The Electrochemical Society, 2019-06-14)Layered cathode materials based on abundant, low cost raw materials have garnered interest in recent years. O3-type NaCrO2 is a promising cathode material as it offers decent energy density and is easy to synthesize. In ... -
Step-wise synthetic approach is necessary to access g-conjugates of folate: folate-conjugated prodigiosenes
(2019)Despite the vast literature that describes reacting folic acid with a pharmacophore, this route is ineffective in providing the correct regioisomer of the resulting conjugate. We herein present a step-wise route to the ... -
Structural and Electrochemical Investigation of FexSi1-x Thin Films in Li Cells
(The Electrochemical Society, 2016-07-20)FexSi1-x thin films with 0 ≤ x ≤ 0.46 have been prepared by combinatorial sputtering and their electrochemical properties have been studied in Li half-cells. X-ray diffraction showed that all of the films had an amorphous ... -
Structural principles and amorphouslike thermal conductivity of Na-doped Si clathrates
(2000-07)The postulated low thermal conductivity and the possibility of altering the electronic conductivity of metal-doped clathrates with semiconducting host elements have stimulated great interest in exploring these compounds ... -

Structure and Disorder of Phosphates in Ag2o-Agi-P2o5 Glasses
(1993-06)We directly probe the microstructure of the different phosphates in several glasses in the Ag2O-AgI-P2O5 system, by means of variable angle correlation NMR spectroscopy. This two-dimensional experiment separates the ... -
Structure, thermal, and transport properties of the clathrates Sr8Zn8Ge38, Sr8Ga16Ge30, and Ba8Ga16Si30
(2004-07)The structural parameters, thermal properties, and transport properties of three type I clathrates, namely Sr8Zn8Ge38, Sr8Ga16Ge30, and Ba8Ga16Si30, have been determined at or below room temperature. The structural ... -
A study of phase transitions in cadmium perchlorate hexahydrate (Cd(ClO4)2.6H2O) by adiabatic calorimetry and infrared spectroscopy.
(1985)A calorimetric study of Cd(ClO4)2.6H2O from 20 to 345 K shows 3 phase transformations, at 124.8, 238.45, and 271.62 K. IR spectra indicate that the low-temp. structure (below 124.8 K) contains 1 type of [Cd(OH2)6]2+, of ... -
