Chemie Ingenieur Technik, EarlyView.In einer konzentrischen Messzelle wurde die Abhängigkeit des Durchgangswiderstandes von Partikelschüttungen von den Produkteigenschaften Partikelgröße und Dispersität in Luft untersucht. Grundsätzlich ist festzustellen, dass mit steigender Partikelgröße der Durchgangswiderstand signifikant ansteigt.

Einstein's 1912-1913 struggles with Gravitation Theory: Importance of Static Gravitational Fields Theory [PDF]
arXiv, 2012 In December 1911, Max Abraham published a paper on gravitation at the basis of which was Albert Einstein's 1911 June conclusion about a relationship between the velocity of light and the gravitational potential. In February 1912, Einstein published his work on static gravitational fields, which was based on his 1911 June theory. In March 1912, Einstein

Gradient‐Free Measurements of Catalyst Plates Using a Berty Reactor
Chemie Ingenieur Technik, EarlyView.A proof‐of‐concept for the adaption of a μ‐Berty reactor for wash‐coated catalyst plates and films is presented on the example of methanol synthesis from CO2. Such a configuration can be used to derive the kinetic parameters and optimize wash‐coat properties under very controlled and idealized conditions before translating them to microchannel or ...

How Amino Acids Intercalate in CaFe Layered Double Hydroxides: A Combined RIXS and NEXAFS Study
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Intercalation of amino acids in layered double hydroxides offers a road to functional (bio)catalysts. With resonant soft x‐ray spectroscopy we probe the electronic structure of these systems and observe activation and passivation of electronic states as well as bond formation between the amino acid and the LDH upon intercalation.

Photocatalytic Oxygen Evolution with Prussian Blue Coated ZnO Origami Core‐Shell Nanostructures
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Prussian Blue and its derivative hold significant potential for photocatalytic oxygen evolution. IN this contribution the photocatalytic oxygen evolution reaction (OER) was characterized using a hybrid catalyst consisting of Prussian Blue coated ZnO nanostructures. The resulting heterojunction, which was characterized both structurally and functionally,

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.What happens, if in the synthesis of flat silver platelets, the slow deposition of silver along twinning faults is disturbed by the addition of a nobler metal? We have looked into it and found a way to fine‐tune the metal deposition in lateral and vertical direction.
