Release and Recapture of Silica Nanoparticles from an Optical Trap in Weightlessness
Govindarajan Prakash, Sven Herrmann, Ralf B. Bergmann +1
Optically trapped Silica nanoparticles are a promising tool for precise sensing of gravitational or inertial forces and fundamental physics, including tests of quantum mechanics at…
Nonequilibrium grain size distribution with generalized growth and nucleation rates
Kimberly S. Lokovic, Ralf B. Bergmann, Andreas Bill
We determine the non-equilibrium grain size distribution during the crystallization of a solid in dimensions at fixed thermodynamic conditions, for the random nucleation and gr…
Non-destructive testing of carbon reinforced plastics by means of phase retrieval
Mostafa Agour, Claas Falldorf, Christoph v. Kopylow +1
In this work, the SLM-based phase retrieval system will be used to inspect carbon reinforced plastics samples (CFRP) under applying a thermal load. For this purpose, the system is…
Misalignment compensation in spatial light modulator based optical filtering techniques
Mostafa Agour, Claas Falldorf, Christoph von Kopylow +1
A new method for the compensation of misalignment in the spatial light modulator based optical linear filtering techniques is presented. It is based on the correlation of the wave…
Time-evolution of grain size distributions in random nucleation and growth crystallization processes
Anthony V. Teran, Ralf B. Bergmann, Andreas Bill
We study the time dependence of the grain size distribution N(r,t) during crystallization of a d-dimensional solid. A partial differential equation including a source term for nucl…
On the Origin of Logarithmic-Normal Distributions: An Analytical Derivation, and its Application to Nucleation and Growth Processes
Ralf B. Bergmann, Andreas Bill
The logarithmic-normal (lognormal) distribution is one of the most frequently observed distributions in nature and describes a large number of physical, biological and even sociolo…
