Mechanism of Molecular Oxygen Reduction at the Cathode of a PEM Fuel Cell : Non-Electrochemical Reactions on Catalytic Pt Particles
TL;DR: In this paper, the effects of different steps, parallel pathways, and side reactions for the oxygen reduction reaction (ORR) mechanism were analyzed for the prominent pathway of ORR in proton exchange membrane (PEM) fuel cells.

Shinjita Acharya,Jan Torgersen,Yongmin Kim,Joonsuk Park,Peter Schindler,Anup L. Dadlani,Martin M. Winterkorn,Shicheng Xu,Stephen Walch,Takane Usui,Christian Schildknecht,Fritz B. Prinz +11 more
TL;DR: In this paper, the first temperature and dose independent thermal BaO deposition using a novel pyrrole-based Ba precursor (py-Ba) and water (H2O) as the co-reactant was reported.
Plasma-Enhanced Atomic Layer Deposition of SiN-AlN Composites for Ultra Low Wet Etch Rates in Hydrofluoric Acid.
Yongmin Kim,J. Provine,Stephen Walch,Joonsuk Park,Witchukorn Phuthong,Anup L. Dadlani,Hyojin Kim,Peter Schindler,Ki-Hyun Kim,Fritz B. Prinz +9 more
TL;DR: This work reports on the development of plasma-enhanced atomic layer deposition (PEALD) composites of SiN and AlN to minimize WER and leakage current density and the role of aluminum and the optimum amount of Al contained in the composite structures have been explored.

- 03 Oct 2008
TL;DR: In this article, a study of the deposition of lead sulfide (PbS) thin films by atomic layer deposition (ALD) was presented, where PbS films were deposited from Pb(tmhd)2 and H2S precursors at precursor sublimation temperatures of 165-175 C.
