Drug-infused nanoparticle is right for sore eyes (10/20/2014)

Drug-infused nanoparticle is right for sore eyesFor the millions of sufferers of dry eye syndrome, their only recourse to easing the painful condition is to use drug-laced eye drops three times a day. Now, researchers from the University of Waterloo have developed a topical solution containing nanoparticles that will combat dry eye syndrome with only one application a week. ...> Full Article


Smallest world record has 'endless possibilities' for bio-nanotechnology (10/19/2014)

Scientists from the University of Leeds have taken a crucial step forward in bio-nanotechnology, a field that uses biology to develop new tools for science, technology and medicine. ...> Full Article


Nanoparticles break the symmetry of light (10/18/2014)

Nanoparticles break the symmetry of lightIf 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. ...> Full Article


Fast, cheap nanomanufacturing (10/17/2014)

Arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply. ...> Full Article


Nano-bearings on the test bench (10/16/2014)

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. ...> Full Article

All directions are not created equal for nanoscale heat sources (10/15/2014)

All directions are not created equal for nanoscale heat sourcesThermal 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. ...> Full Article


Nanoparticles accumulate quickly in wetland sediment (10/14/2014)

Nanoparticles accumulate quickly in wetland sedimentUsing mesocosms that closely approximate wetland ecosystems, researchers show carbon nanotubes accumulate quickly in sediments -- a tendency that could indirectly damage aquatic food chains by piggybacking harmful molecules. ...> Full Article


A new dimension for integrated circuits: 3-D nanomagnetic logic (10/13/2014)

A new dimension for integrated circuits: 3-D nanomagnetic logicElectrical 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. ...> Full Article


Researchers develop new transparent nanoscintillators for radiation detection (10/12/2014)

Researchers develop new transparent nanoscintillators for radiation detectionUS Department of Homeland Security-funded researchers in Texas have identified radiation detection properties in a light-emitting nanostructure made in a new way from two of the least expensive rare earth elements. Their work is being published this week in Optics Letters. ...> Full Article


Smallest-possible diamonds form ultra-thin nanothread (10/11/2014)

Smallest-possible diamonds form ultra-thin nanothreadA team has, for the first time, discovered how to produce ultra-thin 'diamond nanothreads' that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymer fibers. Such exceedingly strong, stiff, and light materials have an array of potential applications, everything from more-fuel efficient vehicles or even the science fictional-sounding proposal for a 'space elevator.' ...> Full Article


World's smallest reference material is big plus for nanotechnology (10/10/2014)

World's smallest reference material is big plus for nanotechnologyThe National Institute of Standards and Technology recently issued Reference Material 8027, the smallest known reference material ever created for validating measurements of these man-made, ultrafine particles between 1 and 100 nanometers -- billionths of a meter -- in size. ...> Full Article


NRL researchers develop novel method to synthesize nanoparticles (10/9/2014)

NRL researchers develop novel method to synthesize nanoparticlesOxide nanoparticles have been shown to be crucial components in numerous applications to include electronic and magnetic devices, energy storage and generation, and as magnetic nanoparticles for use in magnetic resonance imaging. An important advantage of this novel method is the capability of creating bulk quantities of materials in a single step. ...> Full Article


Taking advantage of graphene defects (10/8/2014)

Electronic transport in graphene contributes to its characteristics. Now, the Russian scientist Sergei Koniakhin proposes a new theoretical approach to describe graphene with defects -- in the form of artificial triangular holes -- resulting in the rectification of the electric current within the material. Specifically, the study published in EPJ B provides an analytical and numerical theory of the so-called ratchet effect. ...> Full Article


Nanotechnology leads to better, cheaper LEDs for phones and lighting (10/7/2014)

Nanotechnology leads to better, cheaper LEDs for phones and lightingUsing a new nanoscale structure, the researchers, led by electrical engineering professor Stephen Chou, increased the brightness and efficiency of LEDs made of organic materials -- flexible carbon-based sheets -- by 57 percent. The researchers also report their method should yield similar improvements in LEDs made in inorganic, silicon-based materials used most commonly today. ...> Full Article
