Nature Nanotechnology
Atomically thin solar cells
A lot of research has been done on graphene recently -- carbon flakes, consisting of only one layer of atoms. As it turns out, there are other materials too which exhibit remarkable properties if they are arranged in a single layer. One of them is tungsten diselenide, which could be used for photovoltaics.

New high-tech glasses detect cancer cells during surgery
Scientists at Washington University School of Medicine in St. Louis and the University of Arizona in Tucson led by Samuel Achilefu have created a pair of high-tech glasses that help surgeons visualize cancer cells during surgeries. The technology, reported in the SPIE Journal of Biomedical Optics, incorporates custom video and a head-mounted display capable of capturing signal from any fluorescent molecular agent injected into a patient that attaches to cancer cells, making them glow.

Squeezing light into metals
Using an inexpensive inkjet printer, University of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Crystals ripple in response to light
Minuscule waves that propagate across atom-thin layers of crystal could carry information, light, and heat in nanoscale devices. For the first time, the frequency and amplitude of these waves, called surface phonon polaritons, can be tuned by altering the number of layers of crystals, and they travel far making practical applications for these signals feasible.

First step towards 'programmable materials'
Researchers from Empa and ETH Zurich have succeeded in producing a prototype of a vibration-damping material that could change the world of mechanics forever. The material of the future is not only able to damp vibrations completely; it can also specifically conduct certain frequencies further.

Rough surface could keep small electronic parts from sticking together
When a piece of gift-wrapping tape sticks to itself, it's frustrating, but when small parts in a microgear or micromotor stick together, an electronic device may not work well, if at all. Scientists now report in the journal ACS Applied Materials & Interfaces that rough zinc oxide coatings can prevent tiny silicon parts from adhering to each other. The study could accelerate the development of even more advanced, high-performance electronics and small sensors.

Ultra sensitive detection of radio waves with lasers
Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme precision of measurements.

A new renewable energy source?
Physicists at Harvard SEAS envision a device that would harvest energy from Earth's infrared emissions into outer space. Thanks to recent technological advances, the researchers say, Earth's warmth could soon be transformed into direct-current power, taking advantage of a vast and untapped energy source. Their analysis of the thermodynamics, practical concerns, and technological requirements will be published this week in PNAS.

Newly discovered catalyst could lead to the low-cost production of clean methanol
An international research team has discovered a potentially clean, low-cost way to convert carbon dioxide into methanol, a key ingredient in the production of plastics, adhesives and solvents, and a promising fuel for transportation. Scientists from Stanford, SLAC and the Technical University of Denmark combined theory and experimentation to identify a new nickel-gallium catalyst that converts hydrogen and carbon dioxide into methanol with fewer side-products than the conventional catalyst.
