TL;DR: The aim of this study was to understand the relationship between the redox state of iron-based nanoparticles and their cytotoxicity toward a Gram-negative bacterium, Escherichia coli.
Journal ArticleDOI
A Ferroelectric Oxide Made Directly on Silicon
Maitri Warusawithana,Cheng Cen,Charles R. Sleasman,Joseph C. Woicik,Yulan Li,Lena F. Kourkoutis,Jeffrey A. Klug,Hao Li,Philip Ryan,Li Peng Wang,Michael J. Bedzyk,David A. Muller,Long Qing Chen,Jeremy Levy,Darrell G. Schlom +14 more
TL;DR: Ferroelectric functionality in intimate contact with silicon is achieved by growing coherently strained strontium titanate (SrTiO3) films via oxide molecular beam epitaxy in direct contact with Silicon, with no interfacial silicon dioxide.
Journal ArticleDOI
Diffraction anomalous fine structure: A new x-ray structural technique.
Hans Stragier,Julie O. Cross,John J. Rehr,Larry B. Sorensen,Charles E. Bouldin,Joseph C. Woicik +5 more
TL;DR: It is demonstrated that synchrotron DAFS measurements for the Cu(111) and Cu(222) Bragg reflections provide the same local atomic structural information as x-ray absorption fine structure and how DAFs can be used to provide enhanced site and spatial sensitivities for polyatomic and/or spatially modulated structures is described.
Journal ArticleDOI
Effect of Vinylene Carbonate and Fluoroethylene Carbonate on SEI Formation on Graphitic Anodes in Li-Ion Batteries
Mengyun Nie,Julien Demeaux,Benjamin Young,David R. Heskett,Yanjing Chen,Arijit Bose,Joseph C. Woicik,Brett L. Lucht +7 more
TL;DR: In this paper, the effect of electrolyte additives fluoroethylene carbonate (FEC) and vinylene carbonates (VC) on the structure of the solid electrolyte interface (SEI) was investigated via ex-situ surface analysis including X-ray Photoelectron spectroscopy (XPS), Hard XPS (HAXPES), Infrared spectrograms (IR), and transmission electron microscopy (TEM).
Journal ArticleDOI
Structural changes underlying the diffuse dielectric response in AgNbO 3
Igor Levin,Victor Krayzman,Joseph C. Woicik,Jenia Karapetrova,Thomas Proffen,Matthew G. Tucker,Ian M. Reaney +6 more
TL;DR: In this article, structural differences in the so-called M polymorphs of the AgNbO were analyzed using combined high-resolution x-ray diffraction, neutron total scattering, and electron diffraction measurements.
