Black phosphorus surges ahead of graphene
The research team operating out of Pohang University of Science and Technology, affiliated with the Institute for Basic Science's Center for Artificial Low Dimensional Electronic Systems, reported a tunable band gap in BP, effectively modifying the semiconducting material into a unique state of matter with anisotropic dispersion. This research outcome potentially allows for great flexibility in the design and optimization of electronic and optoelectronic devices like solar panels and telecommunication lasers.

Discovery in growing graphene nanoribbons could enable faster, more efficient electronics
Graphene, an atom-thick material with extraordinary properties, is a promising candidate for the next generation of dramatically faster, more energy-efficient electronics. However, scientists have struggled to fabricate the material into ultra-narrow strips, called nanoribbons, that could enable the use of graphene in high-performance semiconductor electronics. Now, University of Wisconsin-Madison engineers have discovered a way to grow graphene nanoribbons with desirable semiconducting properties directly on a conventional germanium semiconductor wafer.

Camera for the nano-cosmos
To gain even deeper insights into the smallest of worlds, the thresholds of microscopy must be expanded further. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden have succeeded in combining two established measurement techniques for the first time: near-field optical microscopy and ultra-fast spectroscopy. Computer-assisted technology developed especially for this purpose combines the advantages of both methods and suppresses unwanted noise. This makes highly precise filming of dynamic processes at the nanometer scale possible.

Copper clusters capture and convert carbon dioxide to make fuel
The chemical reactions that make methanol from carbon dioxide rely on a catalyst to speed up the conversion, and Argonne scientists identified a new material that could fill this role. With its unique structure, this catalyst can capture and convert carbon dioxide in a way that ultimately saves energy.

New research may enhance display & LED lighting technology
Researchers from the University of Illinois at Urbana-Champaign have developed a new method to extract more efficient and polarized light from quantum dots (QDs) over a large-scale area. Their method, which combines QD and photonic crystal technology, could lead to brighter and more efficient mobile phone, tablet, and computer displays, as well as enhanced LED lighting.

Sandcastles inspire new nanoparticle binding technique
In a paper published this week in Nature Materials, researchers from North Carolina State University and the University of North Carolina-Chapel Hill show that magnetic nanoparticles encased in oily liquid shells can bind together in water, much like sand particles mixed with the right amount of water can form sandcastles.

Brazilian company doubles shelf life of pasteurized fresh milk
A Brazilian company has increased the shelf life of grade A pasteurized fresh whole milk from seven to 15 days. This feat was achieved by incorporating silver-based microparticles with bactericidal, antimicrobial and self-sterilizing properties into the rigid plastic bottles used as packaging for the milk. The microparticles are included as a powder in the polyethylene preform that is used to make plastic bottles by blow or injection molding.

Nature: Compact optical data transmission
Compact optical transmission possibilities are of great interest in faster and more energy-efficient data exchange between electronic chips. One component serving this application is the Mach-Zehnder modulator (MZM) which is able to convert electronic into optical signals. Scientists of KIT and ETH developed a plasmonic MZM of only 12.5 micrometers length which converts digital signals at a rate of 108 gigabit per second, and presented this device in the Nature Photonics journal.

Transparent, electrically conductive network of encapsulated silver nanowires
A team headed by Professor Silke Christiansen has developed a transparent electrode with high electrical conductivity for solar cells and other optoelectronic components -- that uses minimal amounts of material. It consists of a random network of silver nanowires that is coated with aluminium-doped zinc oxide. The novel electrode requires about 70 times less silver than conventional silver grid electrodes, but possesses comparable electrical conductivity.

A cost-effective solution to tuned graphene production
Graphene has been called the miracle material but the single-atomic layer material is still seeking its place in the materials world. Now a method to make 'defective' graphene could provide the answer. Today, in the journal Nanotechnology, a team of researchers report that they have developed a simple electrochemical approach which allows defects to intentionally be created in the graphene, altering its electrical and mechanical properties and making the material even more useful.
