Electron Tomography of Topological Defects in Self-Assembled Bilayers
Publications in Polymer Chemistry
In the article "Supracolloidal Chians of Patchy Micelles in Water" Tai-Lam Nghiem and Tina I. Löbling synthesized a series of bishydrophilic triblock terpolymers via RAFT polymerization with the aim to form supracolloidal chains through a hierarchical self-assembly process.
For that, Tai assembled the terpolymers PEO-b-PS-b-P2VP in "soft" organic solvents to obtain very homogeneous micelles with a PS core and mixed/patchy corona of PEO/P2VP. Transfer to water pH2 then stabilized these micelles due to the double hydrophilic corona. In pH6 however, P2VP collapses and micelles start to form supracolloidal chains of different length and connectivity. The superstructures were analyzed with DLS in our laboratory as well as TEM in the Imaging Center Essen. Follow-up work will focus on polymorphism as well as different stimuli for supracolloidal structure formation.
New Group Member - Alexander Tjaberings
We welcome Alexander Tjaberings from UDE who joined the group on 01.12.17.
He will do his PhD in the Emmy Noether Independent Junior Research Group on the synthesis of functional triblock terpolymers and their self-assembly into topographic nanoparticles and 3D nanoparticle lattices.
New Group Member - Giada Quintieri
We welcome Giada Quintieri from RUB who joined the group on 01.12.17.
She will do her PhD in the Emmy Noether Independent Junior Research Group on the synthesis of functional triblock terpolymers and their self-assembly into topographic nanoparticles and 3D nanoparticle lattices.
New Group Member - Ramzi Chakroun
We welcome Ramzi Chakroun to our group who joined on 01.12.17!
He will be responsible for our dynamic light scattering setup and do his PhD on self-assembled triblock terpolymer nanostructures with special emphasis on following self-assembly kinetics and structure evolution in solution.
Networking-Event at NETZ
The Group organized a networking event with 50+ participants including lectures, dinner and pub quiz.
Publication in Polymer Chemistry
In the article "Polymer brush guided templating on well-defined rod-like cellulose nanocrystals" Maria Morits synthesized cylindrical polymer brushes by grafting diverse polymer chains from the backbone of cellulose nanocrystals (CNCs).
CNCs are rod-like nanoparticles of purely crystalline cellulose and have attracted much attention. These biomaterials are usually incompatible with many other materials and compatibilization of the surface further applications is necessary. Maria could show that grafting can be realized in controlled manner and that sol gel processes in the polymer shell leads to spatially controlled bio-inorganic hybrids.
