Nanoparticles break the symmetry of light
If a particle emits light into one direction, it usually emits just as much light into the opposite direction. By coupling gold particles to glass fibers, scientists from the Vienna University of Technology have succeeded in breaking this symmetry. This turns the gold particle into a switch which can direct light into two different directions in a glass fiber cable.

Nano-bearings on the test bench
'Nano–machines of the future will need tiny devices to reduce friction and make movement possible. The C60 molecule, also known as fullerene or buckyball, seemed to many an excellent candidate for nano-bearings. Unfortunately, the results so far have been conflicting, calling for further studies, like the one carried out by a theoretical team involving the International School for Advanced Studies, the International Center for Theoretical Physics, the National Research Council and the Swiss Federal Laboratories for Materials Science and Technology. Through a series of computer simulations the scientists uncovered the reason for the experimental discrepancies.

Novel approach to magnetic measurements atom-by-atom
Having the possibility to measure magnetic properties of materials at atomic precision is one of the important goals of today's experimental physics. Such measurement technique would give engineers and physicists an ultimate handle over magnetic properties of nano-structures for future applications. In an article published in Physical Review Letters researchers propose a new method, utilizing properties of the quantum world -- the phase of the electron beam -- to detect magnetism with atom-by-atom precision.

All directions are not created equal for nanoscale heat sources
Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A study by researchers from the University of Illinois at Urbana-Champaign has shown that standard thermal models will lead to the wrong answer in a three-dimensional heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.

Ultrafast remote switching of light emission
Researchers from Eindhoven University of Technology can now for the first time remotely control a miniature light source at timescales of 200 trillionth of a second. They published the results on September 2014 in the online journal Nature Nanotechnology. Physicists from the Photonics and Semiconductor Nanophysics group at Eindhoven, under the leadership of prof. Andrea Fiore, have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.

Blades of grass inspire advance in organic solar cells
Briseno's research group is one of very few in the world to design and grow organic single-crystal p-n junctions. He says, 'This work is a major advancement in the field of organic solar cells because we have developed what the field considers the 'Holy Grail' architecture for harvesting light and converting it to electricity.' The breakthrough in morphology control should have widespread use in solar cells, batteries and vertical transistors, he adds.

A new dimension for integrated circuits: 3-D nanomagnetic logic
Electrical engineers at the Technische Universitat Munchen have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors. As CMOS, the main enabling technology of the semiconductor industry, approaches fundamental limits, Technische Universitat Munchen researchers and collaborators at Notre Dame are exploring 'magnetic computing' as an alternative. They report their latest results in the journal Nanotechnology.

A heartbeat away? Hybrid 'patch' could replace transplants
Because heart cells cannot multiply and cardiac muscles contain few stem cells, heart tissue is unable to repair itself after a heart attack. Now Tel Aviv University researchers are literally setting a new gold standard in cardiac tissue engineering, using gold particles to increase the conductivity of biomaterials.

Penn team studies nanocrystals by passing them through tiny pores
An interdisciplinary team of University of Pennsylvania researchers has now applied a cutting-edge technique for rapid gene sequencing toward measuring other nanoscopic structures. By passing nanoscale spheres and rods through a tiny hole in a membrane, the team was able to measure the electrical properties of those structures' surfaces. Their findings suggest new ways of using this technique, known as 'nanopore translocation,' to analyze objects at the smallest scale.
