Multiple Potentials of Maximum Entropy for a Na2Co[Fe(CN)6] Battery Electrode Material: Does the Electrolyte Composition Control the Interface?

Abstract: Development of efficient schemes of energy storage is crucial for finding a solution for the “generation versus consumption” problem. Aqueous Na-ion batteries have been already recognized as one of the promising candidates for large-scale energy-storage systems. Despite noticeable progress in this field, the actual intercalation mechanisms governing these battery cells are yet to be fully comprehended. In this manuscript, we examine the electrode/electrolyte interface formed between electrodeposited Na2Co[Fe(CN)6] films and aqueous solutions. The investigated systems exhibit up to three potentials of maximum entropy (PMEs). To the best of our knowledge, the existence of multiple PMEs in electrochemical systems has never been reported in the literature. These unexpected results are, however, in line with the theory explaining the correlation between the water structure at the interface and the ease of the interfacial mass and charge transfer. Additionally, the obtained PMEs appear to largely depend on the ...

Oberflächenunterstützte großflächige Anordnung von DNA‐Origami‐Kacheln

Abstract: Die grosflachige Anordnung von DNA-basierten Nanostrukturen in geordnete Uberstrukturen ist ein wichtiger Schritt auf dem Weg zu deren Nutzung als funktionale molekulare Materialien. In dieser Arbeit zeigen wir, dass durch elektrostatische Kontrolle der Adhasion und der Mobilitat von DNA-Origami-Strukturen auf Glimmeroberflachen mittels einfacher Zugabe von monovalenten Kationen grose geordnete 2D-Gitterstrukturen aus Origami-Kacheln erzeugt werden konnen. Die Gitter konnen entweder durch dichtes Packen symmetrischer, wechselwirkungsloser DNA-Origami-Strukturen erzeugt werden oder durch Nutzung von Basenstapelwechselwirkungen zwischen Origamieinheiten. Die resultierenden kristallinen Gitter konnen direkt als Vorlage fur die strukturierte Anordnung von Proteinen genutzt werden.

On the physical basis of biological signaling by interface pulses.

Abstract: Currently, biological signaling is envisaged as a combination of activation and movement, triggered by local molecular interactions and molecular diffusion, respectively. However, here, we suggest that other fundamental physical mechanisms might play an at least equally important role. We have recently shown that lipid interfaces permit the excitation and propagation of sound pulses. Here, we demonstrate that these reversible perturbations can control the activity of membrane-embedded enzymes without a requirement for molecular transport. They can thus facilitate rapid communication between distant biological entities at the speed of sound, which is here on the order of 1 m/s within the membrane. The mechanism described provides a new physical framework for biological signaling that is fundamentally different from the molecular approach that currently dominates the textbooks.
