Cathode thickness-dependent tolerance to Cr-poisoning in solid oxide fuel cells

Christos Comninellis, Jan Van Herle, Josef Andreas Schuler, Pietro Tanasini

This work aimed to set new guidelines for the quantification of Cr accumulation in solid oxide fuel cell cathodes after operation, and enabled to pinpoint a diffusion-controlled tolerance to Cr-poisoning for increased cathode thickness; the additional cath ...

Parallel fabrication of polymer-protected nanogaps

Francesco Stellacci, Hua Zhang

A method to create an array of sub-5 nm nanogaps with self-aligned holes in a protective polymer overlayer is presented. The parallel formation of the nanogaps, intended for electrical sensing of biomolecules in an aqueous environment, is achieved by elect ...

Two-Phase Pressure Drops in Adiabatic Horizontal Circular Smooth U-Bends and Contiguous Straight Pipes (RP-1444)

John Richard Thome, Ricardo Lima

Curved channels in the form of bends are encountered in many industrial two-phase flow applications, such as U-bends in air-conditioning and refrigeration evaporators and condensers. For engineering design purposes, the evaluation of the pressure loss in t ...

Microfluidic Protein Preconcentrator Using a Microchannel-Integrated Nafion Strip: Experiment and Modeling

Martinus Gijs, Venkataragavalu Sivagnanam, Meng Shen

We propose a simple microfluidic device for protein preconcentration based on the electrokinetic trapping principle. It comprises a narrow Nafion strip that is simply cut from a commercial membrane and is integrated into a molded poly(dimethylsiloxane) (PD ...

Ray tracing study for non-imaging daylight collectors

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Friedrich Linhart, Stephen Wittkopf, Raphaël Compagnon, Lars Oliver Grobe

This paper presents a novel method to study how well non-imaging daylight collectors pipe diffuse daylight into long horizontal funnels for illuminating deep buildings. Forward ray tracing is used to derive luminous intensity distributions curves (LIDC) of ...
