Researchers demonstrate size quantization of Dirac fermions in graphene
In a recent joint experimental and theoretical work, an international group of physicists demonstrated size quantization of charge carriers, i.e. quantized conductance in nanoscale samples of graphene. The results have been published in an article called 'Size quantization of Dirac fermions in graphene constrictions' in Nature Communications.

How repeated spot microdischarges damage microdevices
In microelectronics, devices made up of two electrodes separated by an insulating barrier are subject to multiple of microdischarges -- referred to as microfilaments -- at the same spot. Now, Jozef Ráhel and colleagues from Masaryk University in the Czech Republic have elucidated the mechanism of microdischarge reoccurrence, by attributing it to the temperature increase in a single microdischarge. These results were recently published in EPJ D.

New type of graphene-based transistor will increase the clock speed of processors
Scientists have developed a new type of graphene-based transistor and using modelling they have demonstrated that it has ultralow power consumption compared with other similar transistor devices. The findings have been published in a paper in the journal Scientific Reports. The most important effect of reducing power consumption is that it enables the clock speed of processors to be increased. According to calculations, the increase could be as high as two orders of magnitude.

Mille-feuille-filter removes viruses from water
A simple paper sheet made by scientists at Uppsala University can improve the quality of life for millions of people by removing resistant viruses from water. The sheet, made of cellulose nanofibers, is called the mille-feuille filter as it has a unique layered internal architecture resembling that of the French puff pastry mille-feuille.

Combining nanotextured surfaces with the Leidenfrost effect for extreme water repellency
Combining superhydrophobic surfaces with Leidenfrost levitation -- picture a water droplet hovering over a hot surface rather than making physical contact with it -- has been explored extensively for the past decade by researchers hoping to uncover the holy grail of water-repellent surfaces. In a new twist, a group of South Korean researchers report an anomalous water droplet-bouncing phenomenon generated by Leidenfrost levitation on nanotextured surfaces in Applied Physics Letters.

At attention, molecules!
University of Iowa chemists have learned about a molecular assembly that may help create quicker, more responsive touch screens, among other applications. The researchers report the interfacial layer -- when molecules interact with a surface -- of electrically charged fluids called ionic liquids is thicker than previously known. Results appear in the journal Langmuir.

Unveiling the electron's motion in a carbon nanocoil
Toyohashi Tech researchers, in cooperation with researchers at University of Yamanashi, National Institute of Technology, Gifu College, and Tokai Carbon Co., Ltd., have? discovered how the electrical resistivity of carbon nanocoils (CNCs) depends on their geometry. The finding, which required development of a new resistivity measuring apparatus, paves the way for CNC-based nanodevices ranging from electromagnetic wave absorbers to nano-solenoids and extra-sensitive mechanical springs.

This 'nanocavity' may improve ultrathin solar panels, video cameras and more
Recently, engineers placed a single layer of MoS2 molecules on top of a photonic structure called an optical nanocavity made of aluminum oxide and aluminum. The results are promising. The MoS2 nanocavity can increase the amount of light that ultrathin semiconducting materials absorb. In turn, this could help industry to continue manufacturing more powerful, efficient and flexible electronic devices.

A better hologram for fraud protection and wearable optics
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have programmed polarization into compact holograms. These holograms use nanostructures that are sensitive to polarization (the direction in which light vibrates) to produce different images depending on the polarization of incident light. This advancement, which works across the spectrum of light, could lead to improvements in anti-fraud holograms as well as those used in entertainment displays.
