July’s edition of Physics World includes an in-depth feature by three Israeli researchers, Marianna Khorzov and David Andelman, from the School of Physics and Astronomy at Tel Aviv University, and Rafi Shikler, from the Electrical and Computer Engineering Department at Ben Gurion University, about exciting developments in the field.
For a long time, plastic was thought of as an insulating material that could not conduct electricity, but ground-breaking research in the 1970s proved that some plastics could do so. Now, more than thirty years later some of the potential applications of these breakthrough materials – electronic billboards, flexible laptops, high-definition television screens only one centimetre thick – are coming to light.
Plastic-based transistors and organic light-emitting displays are set to shake the electronics market. Transistors, the fundamental building block in modern electronic devices, are traditionally made of silicon. Plastic-based transistors however are easier and cheaper to manufacture than their silicon equivalent. And because plastic is flexible, we could soon see ultrathin, flexible laptops, for example, that would be impossible to make from silicon.
Conventional light-emitting displays, used in televisions, iPods and digital watches, are rigid, expensive and complex to manufacture. Organic light-emitting displays, based on plastic electronics engineering, are easier to manufacture, more flexible and, as an added bonus, also consume less energy. This is why Sony, Samsung and Kodak are all devoting time and money to developing them.
Other exciting developments are likely to be in the field of bionics, including the development of materials sensitive but flexible enough to replicate skin, which could be used by robots in situations where a sense of touch is crucial.
The researchers write, “We expect that, for many applications, these materials will gradually replace silicon and metals, and they may even make possible entirely new technologies, particularly in the field of bionics, which seeks to link up technology with biological systems.”

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
