Phase behavior of polymer/mosquito repellent system PLA/DEET

The phase diagram of the binary polymer/mosquito repellent system poly (lactic acid) (PLA) and N,N-diethyl-3-methylbenzamide (DEET) has been established for the purpose of screening the potential use of biodegradable PLA as drug-delivery reservoir for DEET. Crystallization-induced solid-liquid (S-L) phase separation occurs on sufficiently slow cooling of liquid solutions containing crystallizable PLA at temperatures slightly higher than ambient. Non-isothermal crystallization starts spherulitically at point-like nuclei, followed by dendritic crystal growth due to depletion of crystallizable polymer in the solution in the later stage.

Basics in Research Valorization through Entrepreneurship and Intellectual Property (September 18–20, 2017)

Background

Academic and scientific excellence notwithstanding, scientists and academics are challenged with an increasing demand for transfer, exploitation and commercialization of research results. Hence, enabling young researchers to commercialize their ideas either by licensing or selling them for industrial use – or by starting up an own enterprise – becomes more and more important. The challenges comprise legal issues including intellectual property rights, but also aspects of marketing, visualization, communication and the selling of ideas and research findings.

Target Audience

Doctoral students and junior scientists interested in entrepreneurial thinking and acting.

Objectives
  • Survey of basic approaches to research valorization
  • Development of entrepreneurial skills

Talk by T. Thalheim at UL (August 15, 2017)

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. Continue reading “Talk by T. Thalheim at UL (August 15, 2017)”

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.
