Stern Layers on Surfaces of RuO2(100), RuO2(110), and Pt(111): Surface X-ray Scattering Studies
Tomoya Kawaguchi, Reshma R. Rao, Jaclyn R. Lunger +6
Surface X-ray scattering studies of electrochemical Stern layer are reported. The Stern layers formed at the interfaces of RuO2 (110) and (100) in 0.1 M CsF electrolyte are compare…
Studying Internal Compositions of Binary Alloy Pd-Rh Nanoparticles Using Bragg Coherent Diffraction Imaging
Tomoya Kawaguchi, Wonsuk Cha, Vitalii Latyshev +3
Bragg coherent diffraction imaging (BCDI), the well-established technique for imaging internal strain of nanoparticles, was used to image the internal compositional distribution of…
Gas-induced segregation in Pt-Rh alloy nanoparticles observed by in-situ Bragg coherent diffraction imaging
Tomoya Kawaguchi, Thomas F. Keller, Henning Runge +11
Bimetallic catalysts can undergo segregation or redistribution of the metals driven by oxidizing and reducing environments. Bragg coherent diffraction imaging (BCDI) was used to re…
Dynamics of the photoinduced insulator-to-metal transition in a nickelate film
Vincent Esposito, Laurenz Rettig, Elisabeth M. Bothschafter +24
The control of materials properties with light is a promising approach towards the realization of faster and smaller electronic devices. With phases that can be controlled via stra…
In situ and non situ surface x-ray scattering studies of in plane Cs+ ordering in Helmholtz planes of Pt(111) surface
Yihua Liu, Anthony Reiter, Christian Cammarota +4
In-plane ordering of Cs+ layers in Helmhotlz planes was studied on Pt(111) surface in 0.1 M CsF electrolyte solutions with synchtrotron surface x-ray scattering techniques. The ord…
Direct determination of one-dimensional interphase structures using normalized crystal truncation rod analysis
Tomoya Kawaguchi, Yihua Liu, Anthony Reiter +3
A one-dimensional non-iterative direct method was employed for normalized crystal truncation rod. The non-iterative approach, utilizing Kramers-Kronig relation, avoids the ambiguit…
