Sentences with phrase «electron transfer processes»

For fundamental research the key questions are related to the energetics and kinetics of electron transfer processes at interfaces.

Researchers will now have a better sense of what is happening at the catalyst surface and an appreciation for the role of proton and electron transfer processes in this chemistry.

«Strings of electron - carrying proteins may hold the secret to «electric bacteria»: The nanowire structure and electron transfer process of a unique bacterium could provide a foundation for sustainable energy.»

The reaction transfers electrons from the reducing agent to the chloroauric acid, liberating gold atoms in the process.

Thermoelectric cooling is a solid - state refrigeration process where the heat in an electrically conductive material is transferred using the material's own conduction electrons without any need for the gaseous coolants, such as chlorofluorocarbons, that are used in conventional refrigeration.

The mostly likely explanation is that the carbon nanotubes absorb more sunlight and donate electrons to the photosynthetic process, according to Giraldo and the rest of the team, or the nanotubes may be speeding up the transfer of electrons within the photosynthetic processes.

Researchers produce such heating by aiming microwaves at the electrons gyrating around magnetic field lines — a process that increases the thermal energy of the electrons, transfers it to the ions through collisions, and supplements the heating of the ions by neutral beam injection.

The simulations showed that the observed behavior, known as a knock - on process, is consistent with the electron beam transferring energy to individual atoms in the material rather than heating an area of the material.

Necessary inputs include equilibrium potentials, exchange current densities and transfer coefficients for the various interfacial reactions; dielectric properties of electrolytes and electrodes; mobilities of ions and electrons / holes in electrodes and electrolytes; and reaction rate constants of bulk processes (e.g., electron / hole recombination).

This process of transferring electrons is known as doping and induced a giant Stark effect, which tuned the band gap allowing the valence and conductive bands to move closer together, effectively lowering the band gap and drastically altering it to a value between 0.0 ~ 0.6 electron Volt (eV) from its original intrinsic value of 0.35 eV.
