To increase patient safety of keyhole surgery, flexible endoscopy was augmented using magnetic resonance imaging (MRI). For this purpose MR-compatible 9-Fr. flexible endoscopes were developed and tested. Instrument visualisation was achieved using mi

When an exciton approaches the interface between two conjugated polymers, either energy or charge transfer can take place. We present a detailed experimental investigation of these processes in various binary polymer systems. The results are interpre

THE photovoltaic effect involves the production of electrons and holes in a semiconductor device under illumination, and their subsequent collection at opposite electrodes. In many inorganic semiconductors, photon absorption produces free electrons a

Fluorescence scanning near-field optical microscopy (SNOM) is used to investigate binary polyfluorene-based composites of varying composition. The samples investigated contain blends of the polymer poly(9,9′-dioctylfluorene-cobenzothiadiazole), F8B

We use electroabsorption spectroscopy and modeling studies to probe the electric field in light-emitting electrochemical cells. At room temperature and constant applied bias, the steady-state internal field is zero for a range of biases. However, whe
