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.”

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
