Linewidth-limited energy transfer in single conjugated polymer molecules.

Using low temperature single molecule spectroscopy on rigid-rod conjugated polymers we are able to identify homogeneously broadened, strongly polarized emission from individual chromophore units on a single chain. Gated fluorescence spectroscopy allows real time imaging of intramolecular energy transfer as the chain behaves as a series of weakly interacting chromophores. Energy transfer is controlled by the chromophoric spectral linewidth, which depends on temperature. Linewidths exceeding intramolecular disorder lead to incoherent chromophore coupling and collective fluorescence phenomena.

[The severely disabled: a new way of driving a car (author's transl)].

In many cases, the provision of an automobile equipped with a special control system is a necessary part of the rehabilitation of the severely disabled. The car is so important to the disabled as it enables him to overcome daily the distance between home and place of work, hence increasing his mobility and life quality. The presented care control system was developed to meet the individual needs of a particular disability. It is, however, possible to use this system for, or adapt it to, similar types of disabilities. This problem complex has been overcome by following innovations: 1. The electronically controlled accelerator which can be operated with minimal finger pressure. 2. The LIDA shoulder device for tetraplegics, a connecting piece between the shoulder and the manually operated brake lever. 3. The removable armrest on the right hand side of the driver's seat to improve the sitting stability. The car can be easily be converted for "normal driving". The author received financial assistance.
