Die 7. Folge der uni-bonn.tv-Serie "Frag
die Bonner Forscher" beschäftigt sich
mit der Frage, warum die Elemente im
Periodensystem genau auf diese Weise
angeordnet sind. Im Videoclip wird u. a.
der Schalenaufbau der Elektronenhülle
und der daraus resultierende Aufbau
des Periodensystems erklärt.

 

Veröffentlichungen
Chemiker berechnen „Abkürzung“ für Katalysator
O. Hollóczki, S. Gehrke, Angew. Chem. 2017, 10.1002/ange.201708305. (link)
In der Zeitschrift Angew. Chem. stellen Dr. Oldamur Hollóczki, Mulliken Center für Theoretische Chemie der Universität Bonn, und Sascha Gehrke, Mulliken Center für Theoretische Chemie der Universität Bonn und Max-Planck-Institut für Chemische Energiekonversion, einen neuartigen Reaktionsweg für die Organokatalyse mit N-heterozyklischen Carbenen (NHCs)  vor. Der Protonentransfer und die Herstellung der Bindung zwischen Katalysator und Substrat geschehen gleichzeitig in einem einzelnen Elementarschritt, ohne dass eine freie Carbenspezies in der Reaktionsmischung auftritt.

Are There Carbenes in N-Heterocyclic Carbene Organocatalysis?
O. Hollóczki, S. Gehrke, Angew. Chem. Int. Ed. 2017,10.1002/anie.201708305 (link)
A novel reaction pathway for N-heterocyclic carbene organocatalysis has been identified. In this process, proton transfer and the binding of the substrate to the catalyst occur simultaneously in a single elementary reaction step, without the formation of a free carbene molecule in the reaction mixture.

Accessibility Statement

We have undertaken to use our knowledge and understanding of the ways in which different people access the Internet, to develop a web site that is clear and simple for everybody to use.

Validation

We have used XHTML 1.0 and CSS that conforms to specification, as laid out by the W3C because we believe that usability and accessibility must have a solid foundation. If anything on this web site does not validate correctly, please contact the Site Administration , and not the Plone Team.

We have also endeavoured to achieve AA accessibility as measured against version 1.0 of the WCAG. We are aware however, that a number of the checkpoints of the WCAG are subjective — and although we are sure that we have met them squarely, there may be instances where interpretation may vary.
