Multicolor Single Molecule Tracking of Stochastically Active Synthetic Dyes

Julia Gunzenhäuser, Suliana Manley, Aleksandr Benke

Single particle tracking can reveal dynamic information at the scale of single molecules in living cells but thus far has been limited either in the range of potential protein targets or in the quality and number of tracks attainable. We demonstrate a new ...

High-conversion-efficiency organic dye-sensitized solar cells: molecular engineering on D-A-pi-A featured organic indoline dyes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Magdalena Anna Marszalek, Qixing Zhang, Yinghui Wu

This paper reports a new D-A-pi-A organic dye WS-9, which is derived from the known dye WS-2 by incorporating an n-hexylthiophene unit into the pi-conjugation. Due to the presence of a strong electron-withdrawing benzothiadiazole unit in the pi-bridge, the ...

Influence of Donor Groups of Organic D-pi-A Dyes on Open-Circuit Voltage in Solid-State Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Thomas Moehl, Chenyi Yi, Amalie Dualeh, Filippo de Angelis

In solid-state dye-sensitized solar cells (ssDSCs), the poor pore filling of the mesoporous semiconductor and the short diffusion length of charge carriers, in the hole-transport material (HTM) have limited the mesoscopic titania layer to a thickness of 2- ...

On the Applicability of Oil and Dye Technique During the Design Phase and Operation of Experimental Rigs

Alexandros Terzis

In this paper, an oil and dye flow visualization technique applied in two different cases of experimental testing is described, namely a single fan in crossflow and the wake of a compressor cascade. In both cases, the mixture of paint was prepared using a ...

Chemosensors Based on Metal-Dye Complexes for Bioanalytes

Friederike Gundula Marie Zaubitzer

Multicomponent chemosensors were prepared by mixing the rhodium(III) complex [(η5-C5Me5)RhCl 2]2, nickel(II) chloride and/or copper(II) chloride with commercially available dyes in buffered aqueous solution. The sensors were used to detect various biomolec ...
