Current electronic technologies can’t create smaller computers and other devices because they are reaching physical limitations, so University of Arkansas scientists seek to harness an electron’s spin to create tiny machines with large memories. To do this, they have built a microscope that may allow them to be the first researchers to measure the properties of electron spin injection in conducting materials.
Paul Thibado, associate professor of physics, won a $370,000 grant from the National Science Foundation to measure the properties of a spin-based transistor using a customized, two-tip Scanning Tunneling Microscope (STM) system. This work builds on a previous NSF grant of $760,000, which was used to create the customized STM.
Electrons have spin in addition to charge, but in the past this property has been little used or studied. By understanding and using the different states achieved when an electron’s spin rotates, researchers could potentially increase information storage a million fold. This would allow vast quantites of information to be stored in a space the size of a sugar cube or transmitted from one tiny device to another in the blink of an eye.

Styrofoam or copper - both materials have very different properties with regard to their ability to conduct heat. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the University of Bayreuth have now jointly developed and characterized a novel, extremely thin and transparent material that has different thermal conduction properties depending on the direction. While it can conduct heat extremely well in one direction, it shows good thermal insulation in the other direction.
Thermal insulation and thermal conduction play a crucial role in our everyday lives - from computer processors, where it is important to dissipate heat as...
In order to advance the transfer of research developments from the field of quantum sensor technology into industrial applications, an application laboratory is being established at Fraunhofer IAF. This will enable interested companies and especially regional SMEs and start-ups to evaluate the innovation potential of quantum sensors for their specific requirements. Both the state of Baden-Württemberg and the Fraunhofer-Gesellschaft are supporting the four-year project with one million euros each.
The application laboratory is being set up as part of the Fraunhofer lighthouse project »QMag«, short for quantum magnetometry. In this project, researchers...

Researchers from the University Hospital Zurich, ETH Zurich, Wyss Zurich and the University of Zurich have developed a machine that repairs injured human livers and keep them alive outside the body for one week. This breakthrough may increase the number of available organs for transplantation saving many lives of patients with severe liver diseases or cancer.
Until now, livers could be stored safely outside the body for only a few hours. With the novel perfusion technology, livers - and even injured livers - can now...
A balloon-borne scientific instrument designed to study the origin of cosmic rays is taking its second turn high above the continent of Antarctica three and a half weeks after its launch.
SuperTIGER (Super Trans-Iron Galactic Element Recorder) is designed to measure the rare, heavy elements in cosmic rays that hold clues about their origins...
