A detailed look at 2-D structure of turbulence in tokamaks

17-Oct-2017

A key hurdle for fusion researchers is understanding turbulence, the ripples and eddies that can cause the superhot plasma that fuels fusion reactions to leak heat and particles and keep fusion from taking place. Comprehending and reducing turbulence will facilitate the development of fusion as a ...

Seeing the next dimension of computer chips

11-Oct-2017

A research collaboration between Osaka University and the Nara Institute of Science and Technology for the first time used scanning tunneling microscopy (STM) to create images of atomically flat side-surfaces of 3D silicon crystals. This work helps semiconductor manufacturers continue to innovate ...

Creative use of noise brings bio-inspired electronic improvement

27-Sep-2017

In conventional electronics, a great deal of effort is devoted to eliminating stochastic resonance (SR) -- the annoying hiss that generally hinders the detection of weak signals and degrades overall device performance. But, what if there were a way to exploit this effect to enhance signal ...

New method for identifying carbon compounds derived from fossil fuels

15-Sep-2017

Scientists at the National Institute of Standards and Technology (NIST) have developed a laboratory instrument that can measure how much of the carbon in many carbon-containing materials was derived from fossil fuels. This will open the way for new methods in the biofuels and bioplastics ...

A spectroscopic 'science camera' system for smartphones

15-Sep-2017

The latest versions of most smartphones contain at least two and sometimes three built-in cameras. Researchers at the University of Illinois would like to sell mobile device manufactures on the idea of adding yet another image sensor as a built-in capability for health diagnostic, environmental ...

New insights into promising semiconductor material

12-Sep-2017

Researchers from the National University of Singapore (NUS) have established new findings on the properties of two-dimensional molybdenum disulfide (MoS2), a widely studied semiconductor of the future. In two separate studies led by Professor Andrew Wee and Assistant Professor Andrivo Rusydi from ...

Quick and reliable 3-D imaging of curvilinear nanostructures

08-Sep-2017

Physical and biological sciences increasingly require the ability to observe nano-sized objects. This can be accomplished with transmission electron microscopy (TEM), which is generally limited to 2D images. Using TEM to reconstruct 3D images instead usually requires tilting the sample through an ...

Organic photodiodes – more economical detectors for the NIR region

07-Sep-2017

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP will be introducing a new generation of organic photodiodes on silicon substrates (OPD-on-silicon) during the SEMI European Imaging & Sensors Summit 2017. Optical sensors are pervasive. Domestic life as well ...
