Thermophoretic trapping of single molecules

We recently developed a tool which confines Brownian motion by generating temperature gradients – the actual fuel of Brownian motion – with the help of plasmonic structures. The physical phenomenon behind this trapping principle is known as thermophoresis or Ludwig-Soret effect. We are also able to control the number of particles interacting in our trap using an optical feedback algorithm which allows us to set up completely new types of bio-molecular interaction dynamics assays.

I will present results of a single λ-DNA molecule whose center of mass (COM) was trapped. (more…)

14th European Summer School on “Scattering Methods Applied to Soft Condensed Matter”, Gironde, France (19-26 June 2018)

The Bombannes summer school is devoted to the practical «state-of-art» approach to scattering methods, using neutrons, as well as X-ray and light sources – today’s key techniques to study structure and dynamics in systems containing colloids, polymers, surfactants and biological macromolecules.

Since 1990 the Bombannes school series introduces, on a fundamental level, the current methodology of static and dynamic scattering techniques and their applicaiton to soft matter systems. It provides with a period of 2 years advanced training for young researchers with a working place in European laboratories at post-graduate and post-doctoral level.

1. Alumni meeting (September 1, 2017)

Our first alumni meeting will take place on September 1, 2017. We will meet at Peisnitz-Haus at 4pm.

Our first alumni meeting aims at the establishment of links between former and current iRTG members. Former members are invited for talks with focus on their career steps in industry or academia.

Promotion im Umbruch (2017) – Empfehlungen der Leopoldina

Die Promotion ist die eigenständige Durchführung eines wissenschaftlichen Projekts, das durch die Verleihung eines Doktorgrads dokumentiert wird. Das institutionelle Promotionsrecht ist durch staatliche Gesetze geregelt und sieht die Universitäten, gleichgestellte Hochschulen oder entsprechend akkreditierte Institutionen als den Titel verleihende Institutionen vor. Der Promotion liegt eine selbständige Forschungsleistung zugrunde, deren Ergebnis als Dissertation in schriftlicher Form öffentlich gemacht ist.

Das Verständnis, was eine Promotion ist, und die Verfahren zur Erlangung eines wissenschaftlichen Doktorgrads befinden sich im Wandel. Das zeigen die jüngsten hochschulpolitischen Entwicklungen und Diskussionen in Deutschland […]

Founded in 1652, the Leopoldina is one of the oldest academies of science in the world. It is dedicated to the advancement of science for the benefit of humankind and to the goal of shaping a better future. With some 1,500 members, the Leopoldina brings together outstanding scientists from Germany, Austria, Switzerland and many other countries.

NMR investigations of dynamics in the different phases of semicrystalline polymers

The melt-crystallized morphology of semicrystalline polymers strongly depends on the diverse dynamics in the amorphous and crystalline region. The connections between structure formation and dynamics of polymer chains are investigated with SAXS and NMR spectroscopy, respectively, comparing polymers with and without intracrystalline dynamics (crystal-mobile and crystal-fixed). Proton time-domain techniques enable the analysis of the phase components, the intracrystalline and the amorphous phase dynamics. (more…)
