A breakthrough in creating invisibility cloaks, stealth technology
Scientists have managed to create artificial nanostructures that can 'bend light,' called metamaterials. But the challenge has been making enough of the material to turn invisibility cloaks into a practical reality. The work of Debashis Chanda at the University of Central Florida, however, may have just cracked that barrier.

Fabricating nanostructures with silk could make clean rooms green rooms
Tufts University engineers have demonstrated that it is possible to generate nanostructures from silk in an environmentally friendly process that uses water as a developing agent and standard fabrication techniques. This approach provides a green alternative to the toxic materials commonly used in nanofabrication while delivering fabrication quality comparable to conventional synthetic polymers. Nanofabrication is at the heart of manufacture of semi-conductors and other electronic and photonic devices.

Researchers develop technique to measure engineered nanomaterials delivered to cells
Scientists at the Center for Nanotechnology and Nanotoxicology at Harvard School of Public Health have discovered a fast, simple, and inexpensive method to measure the effective density of engineered nanoparticles in physiological fluids, thereby making it possible to accurately determine the amount of nanomaterials that come into contact with cells and tissue in culture. The method will be published in the March 28, 2014 Nature Communications.

Scientists watch nanoparticles grow
With DESY's X-ray light source PETRA III, Danish scientists observed the growth of nanoparticles live. The study shows how tungsten oxide nanoparticles are forming from solution. These particles are used for example for smart windows, which become opaque at the flick of a switch, and they are also used in particular solar cells. The team around lead author Dr. Dipankar Saha from Århus University present their observations in the scientific journal Angewandte Chemie - International Edition.

Scientists track 3-D nanoscale changes in rechargeable battery material during operation
Scientists at Brookhaven Lab have made the first 3-D observations of how the structure of a lithium-ion battery anode evolves at the nanoscale in a real battery cell as it discharges and recharges. The details of this research could point to new ways to engineer battery materials to increase the capacity and lifetime of rechargeable batteries.

Nanotube coating helps shrink mass spectrometers
Nanotechnology is advancing tools that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. When paper used to collect a sample was coated with carbon nanotubes, the voltage required was 1,000 times reduced, the signal was sharpened and the equipment was able to capture far more delicate molecules. The research is detailed in a designated 'very important paper' by the journal Angewandte Chemie.

Unavoidable disorder used to build nanolaser
World around researchers are working to develop nano-optical chips, where light can be controlled. These could be used for future circuits based on light (photons) instead of electrons -- that is photonics instead of electronics. But it has proved to be impossible to achieve perfect photonic nanostructures. Now researchers at the Niels Bohr Institute have shown that imperfect optical chips can be used to produce 'nanolasers,' which is an ultimately compact and energy-efficient light source.

Lightweight construction materials of highest stability thanks to their microarchitecture
KIT researchers have developed microstructured lightweight construction materials of highest stability. Although their density is below that of water, their stability relative to their weight exceeds that of massive materials, such as high-performance steel or aluminum. The lightweight construction materials are inspired by the framework structure of bones and the shell structure of the bees' honeycombs. The results are now presented in the journal PNAS.

Synthetic diamond crystals are of interest to many industrial sectors. Their unique properties make them a suitable material for numerous applications including lenses for high-energy laser optics, X-ray radiation detectors and ophthalmological scalpels. Fraunhofer scientists produce artificial diamonds in all shapes and sizes ranging from discs to three-dimensional shapes and even hollow spheres.

Switching an antibiotic on and off with light
Scientists of the KIT and the University of Kiev have produced an antibiotic, whose biological activity can be controlled with light. Thanks to the robust diarylethene photoswitch, the antimicrobial effect of the peptide mimetic can be applied in a spatially and temporally specific manner. This might open up new options for the treatment of local infections, as side effects are reduced. The researchers present their photoactivable antibiotic with the new photomodule in a 'Very Important Paper' of the journal Angewandte Chemie.

Surprising new way to kill cancer cells
Scientists have demonstrated that cancer cells -- and not normal cells -- can be killed by eliminating either the FAS receptor, also known as CD95, or its binding component, CD95 ligand. The discovery seems counterintuitive because CD95 has previously been defined as a tumor suppressor, scientists said.
