The particle proximity effect: from model to high surface area fuel cell catalysts

Speder, Jozsef; Altmann, Lena; Bäumer, Marcus; Kirkensgaard, Jacob J. K.; Mortensen, Kell; Arenz, Matthias

In this work, Pt nanoparticles prepared by a colloidal method are supported on high surface area carbons. The electrocatalysts synthesized by this method have well-separated, size-controlled nanoparticles with tunable interparticle distance, and thus enable the examination of the particle proximity effect on the oxygen reduction reaction (ORR). The particle proximity…

Pt based PEMFC catalysts prepared from colloidal particle suspensions – a toolbox for model studies

Speder, Jozsef; Altmann, Lena; Roefzaad, Melanie; Bäumer, Marcus; Kirkensgaard, Jacob J. K.; Mortensen, Kell; Arenz, Matthias

A colloidal synthesis approach is presented that allows systematic studies of the properties of supported proton exchange membrane fuel cell (PEMFC) catalysts. The applied synthesis route is based on the preparation of monodisperse nanoparticles in the absence of strong binding organic stabilizing agents. No temperature post-treatment of the catalyst is…

The Effect of Capacity, Rotational Speed and Storage on Crystallization and Rheological Properties of Puff Pastry Butter

Rønholt, S.; Kirkensgaard, J. J. K.; Høyer, K. F.; Mortensen, K.; Knudsen, J. C.

In the margarine and butter industry, sustainable and more efficient refrigerants, such as CO2, are introduced to industrial scraped surface heat exchangers, allowing an increased capacity compared to conventional use of NH3. The effect of such changes in capacity and a varied rotational speed was studied in relation to the…

Shear and Rapeseed Oil Addition Affect the Crystal Polymorphic Behavior of Milk Fat

Kaufmann, Niels; Kirkensgaard, Jacob J. K.; Andersen, Ulf; Wiking, Lars

The effect of shear on the crystallization kinetics of anhydrous milk fat (AMF) and blends with 20 and 30 % w/w added rapeseed oil (RO) was studied. Pulse 1H NMR was used to follow the α to β′ polymorphic transition. The NMR method was confirmed and supported by SAXS/WAXS experiments.…
Surface Chemistry of “Unprotected” Nanoparticles: A Spectroscopic Investigation on Colloidal Particles

Surface Chemistry of “Unprotected” Nanoparticles: A Spectroscopic Investigation on Colloidal Particles

Schrader, Imke; Warneke, Jonas; Neumann, Sarah; Grotheer, Sarah; Swane, Andreas Abildgaard; Kirkensgaard, Jacob J. K.; Arenz, Matthias; Kunz, Sebastian

The preparation of colloidal nanoparticles in alkaline ethylene glycol is a powerful approach for the preparation of model catalysts and ligand-functionalized nanoparticles. For these systems the term ?unprotected? nanoparticles has been established because no strongly binding stabilizers are required to achieve stable colloids. Irrespective of this fact, the particles must…
