The massive forming process can consist of consecutive deformation steps. Voids, initiated in preceding forming steps or present from the material production process, can reduce the deformability in the subsequent forming processes. Therefore, this w

To understand the crack growth in massive forming and to consequentially avoid crack growth in workpieces, it is necessary to investigate its dependence on the crack depth and thus on the state of hydrostatic stress. Prior work shows that the crack o

The patterning of conjugated organic materials is of general interest for controlling the emission properties of light emitting devices (LEDs). We employed UV irradiation in the presence of gaseous hydrazine (N 2 H 4 ) to inscribe patterns in films o

Using a color tuning approach reliant on reductive photopatterning, we present red-green-blue electroluminescence from a single layer polymer light-emitting device. To be able to cover the full color range, we employ a single emissive layer consistin

Lightweight design is essential for an economic and environmentally friendly vehicle. Aluminium sheet metal is well known for its ability to improve the strength to weight ratio of lightweight structures. One disadvantage of aluminium is that it is l

In this contribution we investigate the energy transfer efficiency in blend films consisting of poly(fluorene) (PF) as host and a poly(para-phenylenevinylene) (PPV) derivative as guest materials. It is shown that the emission properties of the blend
