Drum beats from a one atom thick graphite membrane
Researchers at TIFR, Mumbai, demonstrate the ability to electrically manipulate the vibrations of a drum, of nanometer scale thickness, a million times smaller than that of human hair. These drums vibrate a whopping 100 million times a second -- which cannot be heard by the ear but can be sensed using small circuits. This can be used to make new kinds of mass sensors. Also, new aspects of fundamental physics could be probed in the future.

Discovery of gold nanocluster 'double' hints at other shape changing particles
Setting out to confirm the predicted structure of the iconic nanocluster, Gold-144, researchers discovered an entirely unexpected atomic arrangement. The two structures, described for the first time in a new study in Nature Communications, are chemically identical but uniquely shaped, suggesting they also behave differently.

Novel capping strategy improves stability of perovskite nanocrystals
Perovskite materials have shown great promise for use in next-generation solar cells and LEDs, but their instability remains a critical limitation. Atoms on the surface are vulnerable to reactions that can degrade the material, so molecules that bind to the surface (capping ligands) are used both to stabilize perovskite nanocrystals and to control their properties. Researchers have used unique branched ligands to synthesize perovskite nanocrystals with greatly improved stability and uniform particle size.

New approach to microlasers
In this week's issue of Nature Photonics, researchers at MIT and Sandia National Laboratories describe a new way to build terahertz lasers that could significantly reduce their power consumption and size, while also enabling them to emit tighter beams, a crucial requirement for most practical applications. The work also represents a fundamentally new approach to laser design, which could have ramifications for visible-light lasers as well.

Miniature scaffolding could support fight against superbugs
Tiny molecular scaffolding that joins molecules together could be the key to our battle against antibiotic resistance. Research published in Bioorganic & Medicinal Chemistry Letters shows that carbon nanodot scaffolding assembled with small molecules called polyamines can kill some dangerous drug-resistant bacteria, including Acinetobacter baumanii and Klebsiella pneumonia.

Lung research -- EU Horizon 2020 funding to predict nanotoxicity
Scientists at the Helmholtz Zentrum München have received more than €1 million in the framework of the European Horizon 2020 Initiative. Dr. Tobias Stöger and Dr. Otmar Schmid from the Institute of Lung Biology and Disease and the Comprehensive Pneumology Center will be using the funds to develop new tests to assess risks posed by nanomaterials in the airways. This could contribute to reducing the need for complex toxicity tests.

DNA shaping up to be ideal framework for rationally designed nanostructures
Scientists developed two DNA-based self-assembly approaches for desired nanostructures. The first approach allows the same set of nanoparticles to be connected into a variety of three-dimensional structures; the second facilitates the integration of different nanoparticles and DNA frames into interconnecting modules, expanding the diversity of possible structures. These approaches could enable the rational design of nanomaterials with enhanced or combined optical, electric, and magnetic properties to achieve desired functions.

New nanomaterial offers promise in bendable, wearable electronic devices
An ultrathin film that is both transparent and highly conductive has been produced by a cheap and simple method devised by an international team of researchers from the University of Illinois at Chicago and Korea University. The film -- a mat of tangled nanofiber, electroplated to form a 'self-junctioned copper nano-chicken wire' -- is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.

The use of nanoparticles and bioremediation to decontaminate polluted soils
The Basque Institute of Agricultural Research and Development Neiker-Tecnalia is currently exploring a strategy to remedy soils contaminated by organic compounds containing chlorine (organochlorine compounds). The innovative process consists of combining the application of zero-iron nanoparticles with bioremediation techniques. The companies Ekotek and Dinam, the UPV/EHU-University of the Basque Country and Gaiker-IK4 are also participating in this project known as NANOBIOR.

Tiny diamonds could enable huge advances in nanotechnology
University of Maryland researchers developed a new, quick and inexpensive method for constructing diamond-based hybrid nanoparticles in large quantities from the ground up, thereby circumventing many of the problems with current methods. The process begins with nanoscale diamonds containing a 'nitrogen vacancy' impurity that confers special optical and electromagnetic properties. By attaching metal particles or semiconducting'"quantum dots,' the researchers can create various hybrid nanoparticles, including nanoscale semiconductors and magnets with precisely tailored properties.
