Simon Aßmann: Monitoring Spray Flame Synthesis
Spray flame synthesis is a powerful tool for the generation of functionalized nanoparticles, yet sophisticated measurement techniques are required to investigate droplet evolution and nanoparticle formation in such a complex process. In his recent publication, “In Situ Determination of Droplet and Nanoparticle Size Distributions in Spray Flame Synthesis by Wide-Angle Light Scattering (WALS)”, Simon Aßmann […]Spray flame synthesis is a powerful tool for the generation of functionalized nanoparticles, yet sophisticated measurement techniques are required to investigate droplet evolution and nanoparticle formation in such a complex process.

Manuel Kerscher: Characterizing Fluids using Laser Light
For the first time, Manuel Kerscher determined the “Viscosity and Surface Tension of Benzene at Saturation Conditions from Surface Light Scattering”. His results consolidate the capability of surface light scattering as an accurate absolute measurement technique for the simultaneous determination of the viscosity and surface tension of fluids. In addition, his data complement the established […]For the first time, Manuel Kerscher determined the “Viscosity and Surface Tension of Benzene at Saturation Conditions from Surface Light Scattering”.

Maximilian Piszko: Characterizing Mixtures and Melts
Thermoplastic foams are used in a broad variety of applications. The resulting foam properties are governed by the nucleation and bubble growth behavior, which are both strongly influenced by the thermophysical properties of the blowing-agent-loaded polymer melt. Especially knowledge on diffusion coefficients in corresponding mixtures is of importance for understanding and characterizing the kinetics of […]Thermoplastic foams are used in a broad variety of applications.
