Hierarchical self‐assembly is achieved using a visible light triggered photoreaction. A pro‐gelator, α‐diketone‐2,3‐didecyloxyanthracene, is photoconverted into a low molecular weight gelator, 2,3‐didecyloxyanthracene (DDOA), that self‐assembles into nanofibers. Spatial confinement and patterns of these nanofibers onto a surface are achieved by localizing initial nucleation with a focused laser and...
In his book The future of human nature, Jürgen Habermas argues against a scenario of liberal eugenics, in which parents are free to prenatally manipulate their children’s genetic constitution via germline interventions. In this paper, I draw attention to the fact that his species‐ethical line of argument is pervaded by a substantial ambiguity between an argument from actual intervention (AAI) and...
With the help of a Virtual Reality-System (VR system) an exposure therapy can be done comfortably within the usual treatment room of the psychologist. The presented Acrophobia Therapy with Virtual Reality (AcTiVity-System) is constructed to be such a treatment instrument. Due to the integration of an avatar and the use of the Oculus Rift it positively differs from common VR system. In an evaluation...
The geometrical properties of streamline segments (Wang, 2010 [1]) and their bounding surface (Schaefer et al., 2012 [2]) in direct numerical simulations (DNS) of different types of turbulent flows at different Reynolds numbers are reviewed. Particular attention is paid to the geometrical relation of the bounding surface and local and global extrema of the instantaneous turbulent kinetic energy field...
