Atomistic simulation of bio-relevant ionic and organic species interacting with rutile - Towards the understanding of apatite formation

Azade Yazdan Yar

Atomistic simulation methods, namely molecular dynamics and well-tempered metadynamics, are used in this thesis to investigate apatite formation from different aspects. First, ions which are more abundant in SBFs under physiological conditions were identif ...

Deactivation Aspects of Methane Oxidation Catalysts Based on Palladium and ZSM-5

Davide Ferri

Catalytic methane oxidation is used in exhaust gas after treatment to reduce methane emissions in stationary combustion processes as well as in natural gas vehicles. Pd/zeolite catalysts provide higher activity than the commonly used Pd/Al2O3, but suffer f ...

Membrane electrode assembly fabricated with the combination of Pt/C and hollow shell structured-Pt-SiO2@ZrO2 sphere for self-humidifying proton exchange membrane fuel cell

Andreas Züttel, Heena Yang, Youngdon Ko

The Pt-supported hollow structured Pt-HZrO2 with the shell thickness of 27 nm is successfully synthesized. The water retention ability of Pt-HZrO2 is significantly enhanced compared with that of SiO2@ZrO2 due to the hydrophilic hollow structured HZrO2 with ...

Hydrogen Storage in the Expanded Pore Metal-Organic Frameworks M-2(dobpdc) (M = Mg, Mn, Fe, Co, Ni, Zn)

Wendy Lee Queen

The hydrogen storage properties of a new family of isostructural metal organic frameworks are reported. The frameworks M-2(dobpdc) (M = Mg, Mn, Fe, Co, Ni, Zn; dobpdc(4-) = 4,4'-dioxidobiphenyl-3,3'-dicarboxylate) are analogous to the widely studied M-2(do ...
