Rice technique points toward 2-D devices
Rice scientists have created a process to make patterns in atom-thick layers that combine a conductor -- graphene -- and an insulator -- hexagonal boron nitride. The process may lead to new possibilities for two-dimensional electronics.

INRS develops a nanohybrid with remarkable properties using a new laser-plasma process
By achieving the synthesis of a novel nanohybrid structure by means of the pulsed laser ablation technique, Professor My Ali El Khakani and his team paved the way for a new generation of optoelectronic materials. The combination of carbon nanotubes and lead sulfide nanoparticles was performed using an effective and relatively simple process that offers considerable latitude for creating other nanohybrids for a variety of applications.

DNA and quantum dots: All that glitters is not gold
A NIST team has shown that by bringing gold nanoparticles close to the dots and using a DNA template to control the distances, the intensity of a quantum dot's fluorescence can be predictably increased or decreased. This breakthrough opens a potential path to using quantum dots as a component in better photodetectors, chemical sensors, and nanoscale lasers.

Quantum communication: Each photon counts
Ultrafast, efficient, and reliable single-photon detectors are among the most sought-after components in photonics and quantum communication, which have not yet reached maturity for practical application. Physicist Dr. Wolfram Pernice of the Karlsruhe Institute of Technology, in cooperation with colleagues at Yale University, Boston University, and Moscow State Pedagogical University, achieved the decisive breakthrough by integrating single-photon detectors with nanophotonic chips.

Black silicon can take efficiency of solar cells to new levels
Scientists at Aalto University, Finland, have demonstrated results that show a huge improvement in the light absorption and the surface passivation on highly absorbing silicon nanostructures. This has been achieved by applying atomic layer coating. The results advance the development of devices that require high sensitivity light response such as high efficiency solar cells.

PNNL awarded $2.8 million to keep troops cool while using less fuel
Pacific Northwest National Laboratory has been awarded $2.8 million to adapt its energy-efficient adsorption chilling system for field military bases. The system could use up to half as much diesel as today's technology, which could also save soldiers' lives by reducing attacks on troops who transport fuel in the battlefield.

Love triumphs over hate to make exotic new compound
Northwestern University graduate student Jonathan Barnes had a hunch for creating an exotic new chemical compound, and his idea that the force of love is stronger than hate proved correct. He and his colleagues are the first to permanently interlock two identical tetracationic rings that normally are repelled by each other. Many experts had said it couldn't be done. The new compound has attractive electronic characteristics and can be made quickly and inexpensively.

Nanoparticles digging the world's smallest tunnels
The world's smallest tunnels have a width of only a few nanometers. Researchers from Karlsruhe Institute of Technology and Rice University, USA, have dug such tunnels into graphite samples. This will allow structuring of the interior of materials through self-organization in the nanometer range and tailoring of nanoporous graphite for applications in medicine and battery technology.

EMBL-EBI researchers make DNA storage a reality
Researchers at the EMBL-European Bioinformatics Institute have created a way to store data in the form of DNA – a material that lasts for tens of thousands of years. The new method, published today in the journal Nature, makes it possible to store at least 100 million hours of high-definition video in about a cup of DNA.

Image sensors out of a spray can
Researchers from Technische Universität München have developed a new generation of image sensors that are more sensitive to light than the conventional silicon versions, with the added bonus of being simple and cheap to produce. They consist of electrically conductive plastics, which are sprayed on to the sensor surface in an ultra-thin layer. The chemical composition of the polymer spray coating can be altered so that even the invisible range of the light spectrum can be captured.

New way to kill lymphoma without chemotherapy
Scientists annihilated lymphoma by depriving it of a favorite food: HDL cholesterol. Northwestern researchers developed a new golden nanoparticle that's a replica of natural HDL. Acting like a secret double agent, the particle appears to the human lymphoma cell like natural HDL. But when the cell engages it, the particle plugs up the cell and blocks cholesterol from entering. The cell dies.
