Nanocrystals not small enough to avoid defects
A team of researchers from Berkeley Lab and other institutes has shown that contrary to computer simulations, the tiny size of nanocrystals is no safeguard from defects. Studies at Berkeley Lab's Advanced Light Source show that dislocations can form in the finest of nanocrystals when stress is applied.

Novel NIST process is a low-cost route to ultrathin platinum films
A NIST research group has developed a relatively simple, fast and effective method of depositing uniform, ultrathin layers of platinum atoms on a surface. Platinum is a widely used industrial catalyst as well as a key component in microelectronics, so the discovery may have widespread application in the design and manufacture of platinum-based devices.

Reality check for DNA nanotechnology
Two major barriers to advancement of DNA nanotechnology beyond the research lab have been knocked down. This emerging technology employs DNA as a programmable building material for nanometer-scale structures. Many applications are envisioned, and researchers recently demonstrated synthetic membrane channels made from DNA. Until now, however, design processes were hobbled by a lack of feedback; assembly was slow and often of poor quality. Now, as reported in PNAS and Science, researchers have removed these obstacles.

Building better structural materials
When materials are stressed, they eventually change shape. Initially these changes are elastic, and reverse when the stress is relieved. When the material's strength is exceeded, the changes become permanent. This could result in the material breaking or shattering, but it could also re-shape the material, such as a hammer denting a piece of metal. Understanding this last group of changes is the focus of research from a team including Carnegie's Ho-kwang "Dave" Mao.

Got food allergies? Thanks to UCLA, you can test your meal on the spot using a cell phone
A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a lightweight device called the iTube, which attaches to a common cell phone to detect allergens in food samples. The iTube attachment uses the cell phone's built-in camera, along with an accompanying smart-phone application that runs a test with the same high level of sensitivity a laboratory would.

UT Arlington research team wins $1.35 million NSF robotics grant to develop smart skin applications
Imagine a human-like robot with skin and clothes embedded with sensors that could help machines better assist human owners. Such "smart" robots are part of a new $1.35 million National Science Foundation project led by Dan Popa, a UT Arlington associate professor of electrical engineering. Popa is leading a collaborative effort to advance robots and robotic devices, improve prosthetics and enable those devices to perform tasks that people can no longer do themselves.

World's smallest reaction chamber
The world's smallest reaction chamber, with a mixing volume measured in femtolitres (million billionths of a litre), can be used to study the kind of speedy, nanoscale biochemical reactions that take place inside individual cells. By combining two electrospray emitters, not only can such reactions occur but the resulting products can be determined by mass spectrometry.

Flexible silicon solar-cell fabrics may soon become possible
For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that is capable of being scaled up to many meters in length. The research, led by a Penn State University chemist, opens the door to the possibility of weaving together solar-cell silicon wires to create flexible, curved, or twisted solar fabrics.

X-ray laser helps slay parasite that causes sleeping sickness
An international team of scientists, using the world's most powerful X-ray laser, has revealed the 3D structure of a key enzyme that enables the single-celled parasite that causes African trypanosomiasis (or sleeping sickness) in humans. With the elucidation of the 3D structure of the cathepsin B enzyme, it will be possible to design new drugs to inhibit the parasite that causes sleeping sickness, leaving the infected human unharmed.

Morphing DNA hydrogel flows like liquid but remembers its original shape
A new material created by Cornell researchers is so soft it can flow like a liquid and then, strangely, return to its original shape. The hydrogel, a mesh of organic molecules with many small empty spaces that can absorb water like a sponge, qualifies as a "metamaterial" with properties not found in nature and may be the first organic metamaterial with mechanical meta-properties.

Large pores
Researchers of the KIT Institute of Functional Interfaces, Jacobs University Bremen, and other institutions have developed a new method to produce metal-organic frameworks (MOFs). By means of the so-called liquid-phase epitaxy, the scientists succeeded in producing a new class of MOFs with a pore size never reached before. These frameworks open up interesting applications in medicine, optics, and photonics. The new class of MOFs, called "SURMOF 2", is presented in the Nature Scientific Reports journal.
