Major leap towards graphene for solar cells
Dr. Marc Gluba and Professor Dr. Norbert Nickel of the HZB Institute for Silicon Photovoltaics have shown that graphene retains its impressive set of properties when it is coated with a thin silicon film. These findings have paved the way for entirely new possibilities to use in thin-film photovoltaics.

3-D printed microscopic cages confine bacteria in tiny zoos for the study of infections
University of Texas at Austin researchers have used a novel 3-D printing technology to build homes for bacteria at a microscopic level. Their method uses a laser to construct protein "cages" around bacteria in gelatin. The resulting structures can be of almost any shape or size, and can be moved around in relationship to other structures containing bacterial microcommunities.

Cells prefer nanodiscs over nanorods
For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into cells. Now researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods.

Laying down a discerning membrane
One of the thinnest membranes ever made is also highly discriminating when it comes to the molecules going through it. Engineers at the University of South Carolina have constructed a graphene oxide membrane less than 2 nanometers thick with high permeation selectivity between hydrogen and carbon dioxide gas molecules.

DNA nanotechnology opens new path to super-high-resolution molecular imaging
A team at the Wyss Institute for Biologically Inspired Engineering at Harvard University has been awarded a special $3.5 million grant from the National Institutes of Health to develop an inexpensive and easy-to-use new microscopy method that uses blinking DNA probes to spot many tiny components of cells simultaneously. The method could potentially lead to new ways of diagnosing disease and new insights into how the cell's components carry out their work.

Great potential for faster diagnoses with new method
The more accurately we can diagnose a disease, the greater the chance that the patient will survive. That is why many researchers are working to improve the quality of the diagnostic process. Researchers at the Nano-Science Center, University of Copenhagen have discovered a method that will make the process faster, cheaper and more accurate. This is possible, because they are combining advanced tools used in physics for research in biology at nanoscale, two scientific disciplines usually very distant from each other.

UC Berkeley, Berkeley Lab announce Kavli Energy NanoSciences Institute
The Kavli Foundation has endowed a new institute at UC Berkeley and Lawrence Berkeley National Laboratory to explore the basic science of how to capture and channel energy on the molecular or nanoscale, with the potential for discovering new ways of generating energy for human use. The researchers seek to understand how solar, heat and vibrational energy are captured and converted into useful work by plants and animals or novel materials.

New method allows quantitative nanoscopic imaging through silicon
A team of scientists from The University of Texas at Arlington and MIT has figured out how to quantitatively observe cellular processes taking place on so-called "lab on a chip" devices in a silicon environment. The new technology, which is published in Nature's online journal Scientific Reports, will be useful in drug development as well as disease diagnosis, researchers say.

Solar power's future brawl

'Waviness' explains why carbon nanotube forests have low stiffness
A new study has found that "waviness" in forests of carbon nanotubes dramatically reduces their stiffness. Instead of being a detriment, the waviness may make the nanotube arrays more useful as thermal interface material for conducting heat away from future high-powered integrated circuits.

Improving lithium-ion batteries with nanoscale research
New research led by an electrical engineer at the University of California, San Diego is aimed at improving lithium-ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers created nanowires that block diffusion of lithium across their silicon surface and promote layer-by-layer axial lithiation of the nanowire's germanium core.

UW engineers invent programming language to build synthetic DNA
A team led by the University of Washington has developed a programming language for chemistry that it hopes will streamline efforts to design a network that can guide the behavior of chemical-reaction mixtures in the same way that embedded electronic controllers guide cars, robots and other devices. The findings were published online Sept. 29 in Nature Nanotechnology.

The world's sharpest X-ray beam shines at DESY
The world's sharpest X-ray beam shines at DESY. At the X-ray light source PETRA III, scientists from Göttingen generated a beam with a diameter of barely 5 nanometres -- this is ten thousand times thinner than a human hair. This fine beam of X-ray light allows focusing on smallest details. The research groups of Professor Tim Salditt and of Professor Hans-Ulrich Krebs of University of Göttingen published their work in the research journal Optics Express.

Wagon-wheel pasta shape for better LED
One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or LED. University of Utah physicists believe they have solved the problem by creating a new organic molecule that is shaped like rotelle -- wagon-wheel pasta -- rather than spaghetti.

Tiny antennas let long light waves see in infrared
University of Illinois at Urbana-Champaign researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared spectrum. The semiconductor antenna arrays allow long-wavelength light to strongly interact with nano-scale substances, so the arrays could enhance the detection of small volumes of materials.

With carbon nanotubes, a path to flexible, low-cost sensors
Researchers at the Technische Universitaet Muenchen are showing the way toward low-cost, industrial-scale manufacturing of a new family of electronic devices. A leading example is a gas sensor that could be integrated into food packaging to gauge freshness, or into compact wireless air-quality monitors. Flexible pressure and temperature sensors could be built into electronic skin. All these devices can be made with carbon nanotubes, sprayed like ink onto flexible plastic sheets or other substrates.

New multifunctional topological insulator material with combined superconductivity
By employing state-of-art materials design methods, Dr. Binghai Yan and his collaborators from the Max Planck Institute for Chemical Physics of Solids and Mainz University have recently predicted that the oxide compound BaBiO3 combines two required properties, i.e., topological insulator and superconductivity. This material has been known as a high-temperature superconductor of Tc of nearly 30 Kelvin with p-type doping. Now it has been discovered to be also a topological insulator with n-type doping.
