Researchers at Ohio State University and their colleagues have expanded the possibilities for a new kind of electronics, known as spintronics.
Though spintronics technology has yet to be fully developed, it could result in computers that store more data in less space, process data faster, and consume less power. It could even lead to computers that “boot up” instantly, said Arthur J. Epstein, professor of physics and chemistry and director of Ohio States Center for Materials Research.
Spintronics uses magnetic fields to control the spin of electrons. In the current issue of the journal Advanced Materials, Epstein and his coauthors report using a magnetic field to make nearly all the moving electrons inside a sample of plastic spin in the same direction, an effect called spin polarization. Achieving spin polarization is the first step in converting the plastic into a device that could read and write spintronic data inside a working computer.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
