Electron Transfer Theory in Single Molecule Studies of Intermittent Fluorescence of Quantum Dots and in Initial Steps in Dye Sensitized Solar Cells
Intermittently fluorescing single molecule systems are found in many materials, including semiconductor quantum dots (QD), dyes on crystalline or nanoparticle film surfaces, and biological systems. The QD's show a ~ -3/2 power law for the distributio....

A historical overview is presented of the experimental development of ever shorter laser pulses from 1960 to the present. Already in the early sixties nanosecond pulses were achieved and the entry into the picosecond domain was reached in the late s....

Standing spinwaves and surface waves in layered magnetic structures can be used for the detection and quantitative evaluation of interlayer exchange coupling (IEC). Using this method antiferromagnetic IEC has been found in Fe/Cr/Fe layered structure....

Professor Martin Chalfie regrets the disproportionately high funding of translational research, defined as applied research for the treatment of human diseases. With examples from the research in his lab he wants to show how important nontranslatio....

We consider two fields of single molecule studies of intermittently fluorescing systems. In both fields the intermittency is assumed to involve diffusion controlled electron transfer. One of these studies involves the initial steps in dye-sensiti....

The discovery of superconductivity in hole doped La2CuO4 was motivated by the interest to find this phenomenon in an oxide. After the discovery near 35 K, copper oxides with transition temperatures of up to 131 K at normal pressure were found, i.e.....
