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 of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
