Physical Review B
A quantum dot energy harvester
A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient. The engines would be microscopic in size, and have no moving parts. Each would only produce a tiny amount of power but by combining millions of the engines in a layered structure, enough of them could make a notable difference in the energy consumption of a computer.

Detecting cocaine 'naturally'
Since the beginning of time, living organisms have developed ingenious mechanisms to monitor their environment. As part of an international study, a team of researchers has adapted some of these natural mechanisms to detect specific molecules such as cocaine more accurately and quickly. Their work may greatly facilitate the rapid screening -- less than five minutes -- of many drugs, infectious diseases, and cancers.

Building a biochemistry lab on a chip
Miniaturized laboratory-on-chip systems promise rapid, sensitive, and multiplexed detection of biological samples for medical diagnostics, drug discovery, and high-throughput screening. Using micro-fabrication techniques and incorporating a unique design of transistor-based heating, researchers at the University of Illinois at Urbana-Champaign are further advancing the use of silicon transistor and electronics into chemistry and biology for point-of-care diagnostics.

New world record efficiency for thin film silicon solar cells
EPFL's Institute of Microengineering has reached a remarkable 10.7 percent efficiency single-junction microcrystalline silicon solar cell, clearly surpassing the previous world record of 10.1 percent held by the Japanese company Kaneka Corporation since 1998. Such significant efficiency, independently certified by the Fraunhofer Institute for Solar Energy Systems, was achieved with less than two micrometers of photovoltaic active material – 100 times less than with standard techniques.

New material promises better solar cells
A layer cake pretty much tastes like a combination of its individual layers. In materials science, however, combining layers can lead to something completely new. Isolators can take on metallic properties when they are stacked. Scientists in Vienna have now discovered, that layered oxide-structures can be used to create a completely new kind of solar cell. They hope that the new solar cells will replace standard silicon cells in applications, where maximum efficiency is required.

More evidence needed for scale up of mobile device technology in health
Despite the hundreds of pilot studies using mobile health -- also known as 'mHealth'', which describe medical and public health practice supported by mobile devices -- there is insufficient evidence to inform the widespread implementation and scale-up of this technology, according to international researchers writing in this week's PLOS Medicine.

Visualizing biological networks in 4-D
Every great structure depends on specific mechanical properties to remain strong and reliable. Rigidity is of particular importance for maintaining the robust functionality of everything from colossal edifices to the tiniest of nanoscale structures. In biological nanostructures, like DNA networks, it has been difficult to measure this stiffness, which is essential to their properties and functions. But scientists at Caltech have developed techniques for visualizing the behavior of biological nanostructures in both space and time.

Invisible tool enables new quantum experiments
Physicists around Philipp Haslinger and Markus Arndt at the University of Vienna have now succeeded in constructing a novel matter wave interferometer which enables new quantum studies with a broad class of particles, including atoms, molecules and nanoparticles. These lumps of matter are exposed to three pulsed laser light gratings which are invisible to the human eye, exist only for a billionth of a second and never simultaneously. The new results are reported in the advanced online issue of Nature Physics.

Improved X-ray microscopic imaging
X-ray microscopy requires radiation of extremely high quality. In order to obtain sharp images instrument and sample must stay absolutely immobile even at the nanometer scale during the recording. Researchers at the Technische Universitaet Muenchen and the Paul Scherrer Institute in Villigen, Switzerland, have now developed a method that relaxes these hard restrictions. Even fluctuations in the material can be visualized. The renowned journal Nature now reports on their results.
