Autor: Julia E. Parker, Miguel Gomez-Gonzalez, Yolanda Van Lishout, Husn Islam, Desiree Duran Martin, Dogan Ozkaya, Paul D. Quinn, Manfred E. Schuster

Publikováno v: Journal of Synchrotron Radiation, Vol 29, Iss 2, Pp 431-438 (2022)

To improve the understanding of catalysts, and ultimately the ability to design better materials, it is crucial to study them during their catalytic active states. Using in situ or operando conditions allows insights into structure–property relatio

Combining State of the Art Open Source and Proprietary Machine Learning Technologies to Build a Data Analysis Pipeline for Gasoline Particulate Filters using X-Ray Microscopy, Focused Ion Beam-Scanning Electron Microscopy and Transmission Electron Microscopy

Autor: Aakash Varambhia, Angela E. Goode, Ryutaro Sato, Trung Tran, Alissa Stratulat, Markus Boese, Gareth Hatton, Dogan Ozkaya

Publikováno v: Johnson Matthey Technology Review. 66:355-371

The performance of a particulate filter is determined by properties that span the macro, meso and atomic scales. Traditionally, the primary role of a gasoline particulate filter (GPF) is to reduce solid particles and liquid droplets. At the macro sca

Anisotropic elastic strain in Pt-Co catalyst nanoparticles measured by correlated atomic resolution imaging and spectroscopy

Autor: Xiaonan Luo, Aakash Varambhia, Weixin Song, Zhao Shen, Alex Sheader, Dogan Ozkaya, Sergio Lozano Perez, Peter Nellist

Catalysts for the oxygen reduction reaction are crucial to the performance of fuel cell applications. Pt-based alloys have been shown to exhibit superior catalytic activities compared to pure Pt catalysts. Ligand and strain are two fundamental effect

Visualization and Chemical Characterization of the Cathode Electrolyte Interphase Using He-Ion Microscopy and In Situ Time-of-Flight Secondary Ion Mass Spectrometry

Autor: René Heller, Gregor Hlawacek, James Cookson, Dogan Ozkaya, Nico Klingner, Beverley J. Inkson, Laura Wheatcroft

Publikováno v: ACS Applied Energy Materials

Unstable cathode electrolyte interphase (CEI) formation increases degradation in high voltage Li-ion battery materials. Few techniques couple characterization of nano-scale CEI layers on the macroscale with in situ chemical characterization, and thus

Understanding the mechanochemical synthesis of the perovskite LaMnO3 and its catalytic behaviour

Autor: Rachel H. Blackmore, Dogan Ozkaya, Maria Elena Rivas, Martha Briceno de Gutierrez, Trung Dung Tran, Paul Collier, Alison Mary Wagland, Huw R Marchbank, Tugce Eralp Erden, Peter P. Wells

Publikováno v: Dalton Transactions. 49:232-240

Mechanochemistry offers a solventless, ‘waste free’ route to preparing metal oxide catalysts, however, there is limited information on the chemical steps involved. In this work, the perovskite LaMnO3 has been successfully synthesized via mechanoc

Although Pt is extensively used as a catalyst to purify automotive exhaust gas, it is desirable to reduce Pt consumption through size reduction because Pt is a rare element and an expensive noble metal. In this study, we successfully loaded a Pt17 cl
