... molecule side-by-side, or even incorporated into proteins of interest, such as those involved in electron transfer reactions that generate biofuels. As the proteins gain or lose electrons, the ...

... when they seemingly shouldn't. The work sets the stage for a better understanding of the underlying principles of certain reactions common to biofuel production, so-called electron transfer reactions.

... silicon were precisely doped with phosphorus atoms. Quantum information was processed in phosphorus electrons, transferred to phosphorus nuclei, then subsequently transferred back to the electrons. ...

... could come up with the precise folding pattern of cytochrome c, a protein that is part of the mitochondrial electron-transfer chain that turns food into cellular energy. At first the models and the ...

... that the carbon nanotube threads work well as an antenna because of something called the "skin effect." "The electrons transfer well because they want to go to the surface," he says. "Instead of ...

... , sandwiched in between a larger antenna and a complex called the reaction center, where all the electron transfer chemistry takes place. Most of the absorption of light is carried out by a complex ...

... was a real puzzle when Su first did these measurements, but she was able to figure out why." "The electron transfer driving force can be determined by either the properties of the metal cofactors ...

... magnetic fields interact so weakly with molecules," he said. Such chemical reactions involve electron transfers, Schulten said, "which result in freely tumbling spins of electrons. These spins ...

... , similar to a capacitor plate. Within picoseconds, the majority of the laser-accelerated electrons transfer their energy to the target material. This occurs during multiple electron transits through ...

... very low potential, or with a potential somewhere in between. "This unprecedented level of control over an electron-transfer protein was achieved by mapping out the major interactions," Lu said, "an ...

... , very high resolution structure down to 10-25 femtoseconds," Mathies said. Mathies compares proton or electron transfer – the key event in absorption or emission of light – to a worker's trip from ...
