This report provides perspectives on CO2 utilisation from a variety of angles: interviews with scientists, essays on business, environment and social impact, as well as stories from CO2-utilising c...

Oxidative coupling of methane

Fleischer, Vinzenz (2017)

Nowadays, ethene is produced through steam cracking of naptha, which is a fraction of crude oil obtained after its distillation. Ethene is an important basic chemical for the chemical industry, but...

Processing, structuring, and switching of microporous polymers

Becker, Daniel (2017)

This work presents results from three different topics that stand independent from each other. If one wants to find a common denominator connecting all these topics it might be porosity. Whereas th...

Partitioning of membrane components in adhering vesicles

Steinkühler, Jan (2017)

Biological membranes are segmented into functional compartments of different length and time scales. Here we study model systems which mimic certain aspects of these multiscale phaenomena. We intro...

Unravelling ultraslow lithium-ion diffusion in γ-LiAlO2

Wiedemann, Dennis; Nakhal, Suliman; Rahn, Johanna; Witt, Elena; Islam, Mazharul M.; Zander, Stefan; Heitjans, Paul; Schmidt, Harald; Bredow, Thomas; Wilkening, Martin; Lerch, Martin (2016)

Lithium aluminum oxide (γ-LiAlO2) has been discussed and used for various applications, e.g., as electrode coating, membrane, or tritium breeder material. Although lithium-ion diffusion in this sol...

Extended defects in PVT-grown AlN

Langhans, Frank (2016)

The possibility of industrial fabrication of devices based on aluminium nitride bulk crystals is on the one hand limited by the small diameter of state of the art bulk crystals and on the other han...

Quantum chemical studies of transition-metal complexes and aqueous solvent effects

Theilacker, Kolja (2016)

Thanks to the rapid development in the area of computer hardware, and appreciable advances in algorithms and theoretical chemistry methods, quantum chemical calculations have become a crucial tool ...

Adaptation of E. coli towards tryptophan analog usage

Oehm, Stefan (2016)

The presented study set out to change the amino acid set of the genetic code in two different Trp-auxotrophic E. coli strains with the help of the serial transfer regime under constant evolutionary...

Nonlinear nonequilibrium dynamics in a nematic liquid crystal

Stieger, Tillmann (2016)

Liquid crystals are elongated molecules with a rich and surprising phase behavior. Nonequilibrium conditions open a myriad possibilities of manipulating matter, and reach collective states not acce...

Development of local hybrid functionals for time-dependent density functional theory

Maier, Toni Mike (2016)

The present work is concerned with the advancement of the relatively recent class of local hybrid functionals. The first part of the work addresses the conjunction of local hybrid functionals with ...

Depolymerisation von Polysiloxanen und die eisenvermittelte Aktivierung kleiner Moleküle

Döhlert, Peter (2016)

Die vorliegende Arbeit umfasst im ersten Teil Studien zum Recycling von Polysiloxanen. Dazu wurde ein Protokoll zur Depolymerisation entwickelt, bei dem ein Depolymerisationsreagenz und ein Lewis S...

Synthesis and structural characterization of semiconductors based on kesterites

Ritscher, Anna (2016)

The here-presented thesis provides detailed investigations on the structural characteristics of the chalcogenide Cu2ZnSnS4 (CZTS). This semiconductor material is a promising candidate for absorber ...

Synthesis of gold nanoparticle-hydrogel nanocomposites with controlled cytotoxicity and unique cell-adhesive properties

Ren, Fang (2016)

Gold Nanopartikeln (Au NPs) spielen eine bedeutende Rolle in Chemie, Biologie, Ingenieurwesen und Medizin aufgrund ihrer einzigartigen optischen Eigenschaften, leichten Synthese und Flexibilitat in...
