Effects of modeling strategies for a slab track on predicted ground vibrations [Elektronisk resurs]
, 2020 In the paper, the effect of modeling strategies regarding the dynamic behavior of a railway slab track on a layered half-space is studied. The track is modeled with various degrees of accuracy through the use of either beam theory, shell finite elements ...

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts
Advanced Functional Materials, EarlyView.The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...
