Spin transfer torque is the transfer of the spin angular momentum from conduction electrons to the magnetization of a ferromagnet and enables the manipulation of nanomagnets with spin currents rather than magnetic fields,» explained Gyung - Min Choi, who recently completed his PhD in materials science and engineering at Illinois.

Modern electronics is based on the use of electrons as information carriers, but they have ceased to meet the contemporary requirements: standard electrical copper wires and channels on chips can not transfer information with speeds sufficient for modern microprocessors.

Chemin and his colleagues, meanwhile, have shown that the interaction can go both ways: In the 28 August Physical Review Letters, they report that tellurium nuclei primed with the right amount of energy can transfer it to electrons, which in turn give up photons.

«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.

Researchers designed a chip that transfers data not with electrons but with photons — resulting in a potential 10-fold boost in speed.

Bengt Nordéns contribution to form a strong research school in Gothenburg has been successful: as many as 12 out of his about 50 former PhD students and postdocs have become professors, abroad or at other Swedish universities, and three have returned to contribute a forceful environment with their own profiles within the Department: Prof Bo Albinsson (femtosecond spectroscopy and fundamentals of electron transfer), Prof Per Lincoln (new transition - metal - based DNA ligands and statistical mechanics for gene targeting), Prof Björn Åkerman (fundamentals and applications of DNA physical chemistry).

For example, wires with Majoranas at either end can be used to transfer information between far away quantum bits that rely on the spin of electrons.

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.
