Mon, 14.10.2019 - Special lectures

9:00 am @ seminar room 1.30 Von-Seckendorff-Platz 1, 06120 Halle

Prof. Dr. Shi-Qing Wang

Department of Polymer Science, University of Akron, USA

Lecture 1:
“A unified framework to understand  ductility in glassy polymers: from crazing, brittle-to-ductile  transition to rubber-toughened polymers"

Abstract:
In  my lab, we focus on building a molecular-level understanding of polymer  mechanics in both liquid and solid states. This is a journey that  involves three episodes or steps: a. Phenomenology and conceptual  foundation of polymer melt rheology, b. Molecular mechanics of polymer  glasses, c. Brittleness and ductility of semicrystalline polymers. [...]

Lecture 2:
“The essence of nonlinear polymer rheology: everything you must know”

Abstract:
Polymer processing suffers from a variety of rate-limiting difficulties. In extrusion alone, we encounter surface roughness on extrudate (sharkskin), quasi-periodic extrudate distortion associated with pressure oscillation and gross melt fracture. [...]

Aggregation and Crystallization of Synthetic Polymers confined in Lipid Bilayers

Abstract:
A  potential investigation concerning the behavior of synthetic polymers incorporated in lipid bilayers will be described. Emphasis is given on  studying the effects of confinement on crystallization, dynamics and  structure.The methodology is illustrated with previous work on mixtures of lipids and triblock copolymers.

Dr. Martin Tress

Dielectric Spectroscopy at the Limit: Where Isolated Polymer Chains meet Functional Systems

Abstract:
In this talk, I will present my pioneering measurements  of the molecular dynamics in isolated polymer chains, followed by some  aspects of my recent work on associating and crystallizing polymeric  systems. Then, I will combine these fields in a concept for future  research on nano-structured molecular arrangements by means of  dielectric spectroscopy.

Dr. Martin Brehm

Precipitating Cellulose at Ionic Liquid / Water Interfaces

Abstract:
With an approximated 700 billion tons, cellulose is by  far the most abundant organic polymer on earth, and could help to  mitigate the effect of shrinking crude oil resources. There exist some  methods to make commercial products from cellulose for many decades, but  most of them are expensive or involve toxic reagents. Ionic liquids  offer a novel way of cellulose processing without these disadvantages.  However, there is only little microscopic understanding of these  processes today. Within this project, a combination of molecular  dynamics simulations and various spectroscopic methods shall be employed  to gain molecular insight into precipitation and structure formation of  cellulose at ionic liquid / water interfaces.

Instrumentation for Small Angle X-Ray Scattering and
GISAXS/GIWAXS in the Experimental Polymer Physics
Group starts operating

The new instrumentation for small angle xray scattering (SAXS) and GISAXS/GIWAXS in the Experimental Polymer Physics group of T. Thurn-Albrecht started to operate.

With the new instrumentation structures can be investigated over a larger measurement range due to the upgrade to a microfocus source. The investigation of thin polymer films and protein solutions become available by the extension to a semi conductor detector.

Depending on the investigated structure the resolution increases up to 100% or the intensity is up to 20 times higher during the measurements with the new setup from SAXSLAB. Shorter times for each measurement become available due to the higher intensities.

RISE-student Nelyan Lopez Perez visits SFB/TRR 102

RISE-student Nelyan (ri) & phd student Ann-Kristin

RISE-student Nelyan (ri) & phd student Ann-Kristin

Nelyan Lopez Perez, a fourth year undergraduate student at the University of Puerto Rico in Rio Piedras was for the time from 31 May to 28 July 2013 a guest at the SFB / TRR 102 in Halle (Saale). Her stay was possible through the student exchange program RISE of DAAD.
Here she has studied atomic force microscopy of thin polymer films in connection with the project "Substrate-induced molecular order and nucleation of semi-crystalline polymers in thin films" (B03). Nelyan said: "I am very happy that I was selected as a RISE student. Through my stay I learned a lot about soft matter research, as well as about myself. I gained a lot of experience as a scientist here. Through the insight into the field of polymer science more options for my future development have arisen.” During her two-month stay Nelyan was looked after by Diplom-Physikerin (Medizinphysik) Ann-Kristin Löhmann, who is working as a researcher in project B03 of the SFB/TRR 102 research and Prof. Dr. Thomas Thurn-Albrecht, Spokesman of the CRC and head of the research group "Experimental Polymer Physics”. After her guest stay in Halle (Saale), which was also supported by the Puerto Rico NASA Space Grant and a Pfizer fellowship Nelyan turns back to her undergraduate studies. When asked about her plans for the future, Nelyan replied: "By working in the group 'Experimental Polymer Physics' and my time here in Germany I have become much more independent. I now want to finish my Bachelor's degree as quickly as possible and then begin my studies at a graduate school in polymer physics."
