Glass cones shine new light on radially polarised beams

11-Feb-2016

Physicists at the University of Glasgow have developed a new and inexpensive way to make radially polarised white light, which could help scientific advances in astronomy and microscopy. Dr Neal Radwell and Dr Sonja Franke-Arnold, from the University’s School of Physics and Astronomy, have ...

New thin film transistor may lead to flexible devices

11-Feb-2016

An engineering research team at the University of Alberta has invented a new transistor that could revolutionize thin-film electronic devices. Their findings could open the door to the development of flexible electronic devices with applications as wide-ranging as display technology to medical ...

Making sense of metallic glass

11-Feb-2016

If you freeze any liquid fast enough, even liquid metal, it becomes a glass. Vitrified metals, or metallic glasses, are at the frontier of materials science research. They have been made by rapidly cooling alloys of various metals including, zirconium, palladium, iron, titanium, copper, and ...

Superconductivity: footballs with no resistance

Indications of light-induced lossless electricity transmission in fullerenes contribute to the search for superconducting materials

11-Feb-2016

Superconductors have long been confined to niche applications, due to the fact that the highest temperature at which even the best of these materials becomes resistance-free is minus 70 degrees Celsius. Nowadays they are mainly used in magnets for nuclear magnetic resonance tomographs, fusion ...

Riddle of cement’s structure is finally solved

Findings may guide development of formulas to make the material more durable, less CO2-intensive

10-Feb-2016

Concrete is the world’s most widely used construction material, so abundant that its production is one of the leading sources of greenhouse gas emissions. Yet answers to some fundamental questions about the microscopic structure and behavior of this ubiquitous material have remained elusive. ...

A deep look into a single molecule

10-Feb-2016

A German research group has demonstrated the first implementation of a non-destructive state detection technique for molecular ions. Piet Schmidt and his colleagues from the QUEST-Institute at the Physikalisch-Technische Bundesanstalt (PTB) observed changes in the rotational state of a trapped ...

Is lignin the crude oil of the future?

Maybe so, thanks to the Sun and photocatalysts!

09-Feb-2016

We associate refineries with crude oil and a dense tangle of technical fittings. They may, however, change in the future - if crude oil is replaced by lignin, a product currently treated as industrial waste. The research route leading towards this goal is being paved by new photocatalysts, ...

Metal oxide sandwiches: New option to manipulate properties of interfaces

09-Feb-2016

Sandwich systems of thin film transition metal oxides display surprising properties at their interfaces. In case of the paradigmatic example of Lanthan-Aluminate ( LaAlO3) and Strontium-Titanate (SrTiO3) both materials are insulators and non-magnetic, while their interface has been observed to ...

Breakthrough for magnesium lightweight materials

09-Feb-2016

By changing the microstructure in magnesium alloys, Mohsen Esmaily, researcher in Atmospheric Corrosion at Chalmers University of Technology, has succeeded in improving possibilities for the transport sector to use these materials to decrease the weight of vehicles. Magnesium is the lightest ...

The odor of stones

09-Feb-2016

Diatoms are unicellular algae that are native in many waters. They are a major component of marine phytoplankton and the food base for a large variety of marine organisms. In addition, they produce about one fifth of the oxygen in the atmosphere and are therefore a key factor for our global ...
