TL;DR: In this article, the effect of pore size on electrocatalytic performance of carbon-based catalysts for hydrogen peroxide (H2O2) has been explored.
Journal ArticleDOI
Systematic Structure–Property Relationship Studies in Palladium-Catalyzed Methane Complete Combustion
Joshua J. Willis,Alessandro Gallo,Alessandro Gallo,Dimosthenis Sokaras,Hassan Aljama,S. Nowak,Emmett D. Goodman,Liheng Wu,Liheng Wu,Christopher J. Tassone,Thomas F. Jaramillo,Frank Abild-Pedersen,Matteo Cargnello +12 more
TL;DR: In this article, the effect of three important variables (particle size, support, and reaction conditions including water) on the activity of supported Pd catalysts was investigated using uniform palladium nanocrystals as catalyst precursors to systematically describe structure-property relationships with the help from theory and in-situ X-ray absorption spectroscopy.
Journal ArticleDOI
Revealing Electronic Signature of Lattice Oxygen Redox in Lithium Ruthenates and Implications for High-Energy Li-ion Battery Material Designs.
Yang Yu,Pinar Karayaylali,S. Nowak,Livia Giordano,Magali Gauthier,Wesley T. Hong,Ronghui Kou,Qinghao Li,John Vinson,Thomas Kroll,Dimosthenis Sokaras,Cheng-Jun Sun,Nenian Charles,Filippo Maglia,Roland Jung,Yang Shao-Horn +15 more
TL;DR: This study has pinpointed the key spectral fingerprints related to lattice oxygen redox from a molecular level and constructed a transferrable framework to rationally interpret the spectroscopic features by combining advanced experiments and theoretical calculations to design materials for Li-ion batteries and electrocatalysis applications.
Journal ArticleDOI

S. Nowak,Rebecca Armenta,Craig P. Schwartz,Alessandro Gallo,Baxter Abraham,Angel T. Garcia-Esparza,Elisa Biasin,A. Prado,A. Maciel,D. Zhang,David V. Day,Steven T. Christensen,Thomas Kroll,Roberto Alonso-Mori,Dennis Nordlund,Tsu-Chien Weng,Dimosthenis Sokaras +16 more
TL;DR: A high energy resolution x-ray spectrometer for the tender x-rays regime (1.6-5.0 keV) that was designed and operated at Stanford Synchrotron Radiation Lightsource is presented and performance is discussed.
Journal ArticleDOI
Separate measurement of the 5f5/2 and 5f7/2 unoccupied density of states of UO2
James G. Tobin,S. Nowak,Corwin H. Booth,Eve Bauer,S-W Yu,Roberto Alonso-Mori,Thomas Kroll,Dennis Nordlund,Tsu-Chien Weng,Dimosthenis Sokaras +9 more
TL;DR: Coupling High Energy Resolution Fluorescence Detection (HERFD) with electric dipole selection rules, the uranium 5f5/2 and 5f7/2 Unoccupied Densities of States (UDOS) have been determined in UF4, UO2 and UCd11.
