Publikováno v: ChemElectroChem. 4:1390-1394

Developing a functional Cr(III) electrolyte to replace carcinogenic and toxic Cr(VI) electroplating requires a deeper understanding of the deposition mechanisms. Hence, this study investigates and compares the growth of chromium on inert glassy carbo

Mixed SAMs of backbone-functionalized tribenzotriquinacenes and alkanethiols: synthesis, preparation and STM-investigations

Autor: Stefan Henne, Björn Bredenkötter, Dirk Volkmer

We present the synthesis of a backbone-functionalized tribenzotriquinacene (TBTQ) 3 , serving as a prototype for TBTQ-based stators comprising thioether anchor groups for self-assembled monolayers on Au-(1 1 1) surfaces. Self-assembled monolayers (SA

Almost enclosed buckyball joints: synthesis, complex formation, and computational simulations of pentypticene-extended tribenzotriquinacene

Autor: Sareeya Bureekaew, Mohammad Alaghemandi, Rochus Schmid, Stefan Henne, Dirk Volkmer, Björn Bredenkötter

Publikováno v: Chemphyschem : a European journal of chemical physics and physical chemistry. 15(17)

We report the synthesis of a tribenzotriquinacene-based (TBTQ) receptor (3) for C60 fullerene, which is extended by pentiptycene moieties to provide an almost enclosed concave ball bearing. The system serves as a model for a self-assembling molecular

Advanced buckyball joints: synthesis, complex formation and computational simulations of centrohexaindane-extended tribenzotriquinacene receptors for C60 fullerene

Autor: Stefan Henne, Dirk Volkmer, Björn Bredenkötter, Abbas A. Dehghan Baghi, Rochus Schmid

The synthesis of a structurally optimized tribenzotriquinacene receptor 9 is described, which is extended by centrohexaindane moieties to give rise to a half-round concave ball bearing, with optimum shape complementarity towards C(60) fullerene. Spec

Nanosized ball joints constructed from C60 and tribenzotriquinacene sockets: synthesis, component self-assembly and structural investigations

Autor: Björn Bredenkötter, Stefan Henne, Dirk Volkmer

Publikováno v: Chemistry (Weinheim an der Bergstrasse, Germany). 13(35)

The formation of supramolecular host-guest complexes of fullerene (C(60)) and two novel tribenzotriquinacene based hosts (5 a and 5 b) was investigated in solution and in the solid state. Stability constants for 1:1 and 2:1 complexes were obtained fr

Electronic Spatial Assistance for People with Dementia: Choosing the Right Device

Autor: Cornelia Schneider, Stefan Henneberger

Publikováno v: Technologies, Vol 2, Iss 2, Pp 96-114 (2014)

The demographic change and ageing in Europe will lead to a growing number of people suffering from dementia. Consequently, costs for public health will increase because people become more and more reliant on care and gradually lose their independence

Geographielehrerinnen und -lehrer im Spannungsfeld zwischen erworbenen und geforderten Kompetenzen. Eine empirische Studie zur zweiphasigen Lehramtsausbildung

Autor: Sandra Hof, Stefan Hennemann

Publikováno v: Zeitschrift für Geographiedidaktik, Vol 41, Iss 2 (2013)

Teacher training is increasingly becoming a subject of debate in Germany. Unlike in most other countries, the German system consists of two consecutive phases. In the first phase, the teacher-to-be acquires knowledge and skills at a university. This
