First principles approach to creating new materials: Solid-state chemistry and theoretical physics combined to help discover new materials with useful properties

A Perovskite heterostructure: The laws governing the physics of materials are in fact relatively simple, it is just that the behavior of the constituents as a whole are complex. Indeed, materials are made up of atoms whose type, number, and arrangement--the crystalline motif--creates distinct properties that emerge through the collective behavior of the seemingly simpler, well-understood parts. The discovery of emergent phenomena in condensed matter systems is therefore intimately linked with that of discovering the crystalline materials that display these phenomena. Such discoveries by their very nature often occur serendipitously. One challenge is that there are an enormous number of possible bulk compounds that have yet to be identified. As the propensity for new properties tends to increase as the structural and chemical complexity of the crystalline motif increases, the traditional exploratory route to discover these materials is quite demanding.

Global Recovery Offers Opportunity for Growth and Policy Reforms in the Middle East and North Africa

The World Bank Group’s latest regional economic update projects growth in the Middle East and North Africa (MENA) region to accelerate from an average of 2.6% in 2013 to 4.6% in 2015. With the global economy set for a rebound, 2014 seems hopeful and 2015 could be a turning point for countries in the MENA region as they will start to benefit from stronger external demand in the high-income economies.

Rebar technique strengthens case for graphene: Rice University lab makes hybrid nanotube-graphene material that promises to simplify manufacturing

Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University.

Carbon nanotubes that serve as reinforcing bars in graphene partially unzip in the process created at Rice University. The unzipped part of the tube bonds covalently with the graphene sheet, providing an uninterrupted electrical connection.

To bridge LEDs' green gap, scientists think small... really small: Nanostructures half a DNA strand-wide show promise for efficient LEDs

Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the "green gap," a portion of the spectrum where LED efficiency plunges, simulations at the U.S. Department of Energy's National Energy Research Scientific Computing Center (NERSC) have shown.

Quantum Photon Properties Revealed in Another Particle—the Plasmon

For years, researchers have been interested in developing quantum computers—the theoretical next generation of technology that will outperform conventional computers. Instead of holding data in bits, the digital units used by computers today, quantum computers store information in units called "qubits." One approach for computing with qubits relies on the creation of two single photons that interfere with one another in a device called a waveguide. Results from a recent applied science study at Caltech support the idea that waveguides coupled with another quantum particle—the surface plasmon—could also become an important piece of the quantum computing puzzle.
