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…

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 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…

Encapsulation of Functional Organic Compounds in Nanoglass for Optically Anisotropic Coatings

Stöter, Matthias; Biersack, Bernhard; Rosenfeldt, Sabine; Leitl, Markus J.; Kalo, Hussein; Schobert, Rainer; Yersin, Hartmut; Ozin, Geoffrey A.; Förster, Stephan; Breu, Josef

A novel approach is presented for the encapsulation of organic functional molecules between two sheets of 1 nm thin silicate layers, which like glass are transparent and chemically stable. An ordered heterostructure with organic interlayers strictly alternating with osmotically swelling sodium interlayers can be spontaneously delaminated into double stacks with the…
