Cation‐Directed Host–Guest Assembly and Reversible Wheel to Cluster Interconversion in a 20‐Molybdate System

Chemistry – A European Journal, EarlyView.
The polyoxo‐20‐molybdate(VI) wheel [MoVI20O60{AsO2(CH3)2}12]12− (Mo20) can be prepared with or without a central guest in a controlled, cation‐directed fashion. When Mo20 is dissolved in water, it exhibits an immediate, quantitative, and fully reversible solution transformation to a tetranuclear Mo4 cluster, which transforms in the solid state again to

Orbifold Degeneration of Conformally Compact Einstein Metrics

In his investigation of the Dirichlet problem for conformally compact Einstein metrics, Anderson showed that there are (at most) three possibilities for the behavior, under subsequences, of a sequence of conformally compact Einstein metrics, with ...

Prism[5]MaxQ: A Sulfated Prism[5]Arene and Its Molecular Recognition Properties Toward a Panel of Quaternary Ammonium Guests

Chemistry – A European Journal, EarlyView.
We report the synthesis and characterization of a sulfated prism[5]arene host (Prism[5]MaxQ). Prism[5]MaxQ displays ultrahigh binding affinity (Ka up to 1012 M−1) toward hydrophobic (di)cations in phosphate‐buffered saline (PBS). The work positions Prism[5]MaxQ as a new member of the family of ultrahigh‐affinity hosts poised for use as a sequestrant in

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

Chemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

Kahler-Einstein metrics for manifolds with nonvanishing Futakicharacter

, 2001
In this paper, we generalize the concept of Kahler-Einstein metrics for Fano manifolds with nonvanishing Futaki character. Similar to Kahler-Einstein metrics, these new metrics have various nice properties.

225 Jahre UV‐Strahlung – Die Rekonstruktion des Ritter‐Experiments (1801) für Schule und Hochschule

CHEMKON, EarlyView.
Am 22. Februar 1801 gelang Johann Wilhelm Ritter in Jena der experimentelle Nachweis einer unsichtbaren Strahlung jenseits des violetten Bereichs des sichtbaren Spektrums. Als Indikator nutzte er die photochemische Schwärzung von Hornsilber (Silberchlorid) und erbrachte damit erstmals einen indirekten experimentellen Nachweis der ultravioletten ...
