«The direct growth of anchored MoSoy nanocrystals on graphene sheets may enhance the formation of strongly coupled hybrid materials with intimate, seamless electron transfer pathways, thus accelerating the electron transfer rate for the chemical desorption of hydrogen from the catalyst, further reducing the energy required for the reaction to take place,» Sasaki said.

Albert Einstein already explained the «photoelectric effect» in 1905: light transfers energy to an electron, removing it from the metal.

In artificial photosynthesis systems chromophores, or «photosensitizers,» absorb light energy and transfer electrons to the catalyst, which activates the chemical reaction.

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.

Dr. El - Naggar has increased our understanding of electron transfer focusing on bacterial nanowires, and is working to develop new nanomaterials and tools for energy conversion.

Computational studies by the team's theoreticians showed that the dipeptide in the meta position was more compact, making electron transfer faster, because of the smaller energy associated with the necessary twist in the scaffolding, or the ability to get closer to the electrode.

Batteries with multivalent cathodes (which have multiple electrons per mobile ion available for charge transfer) are promising candidates for reducing cost and achieving higher energy density than that available with current lithium - ion technology.

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.
