Linking superconductivity and structure

Superconductivity is a rare physical state in which matter is able to conduct electricity without any resistance. It can only be found in certain materials, and even then it can only be achieved under controlled conditions of low temperatures and high pressures. New research hones in on the structural changes underlying superconductivity in iron arsenide compounds - those containing iron and arsenic.

Who needs water to assemble DNA? Non-aqueous solvent supports DNA nanotechnology

Scientists around the world are using the programmability of DNA to assemble complex nanometer-scale structures. Until now, however, production of these artificial structures has been limited to water-based environments, because DNA naturally functions inside the watery environment of living cells. Researchers have now shown that they can assemble DNA nanostructures in a solvent containing no water.

Fine-tuned molecular orientation is key to more efficient solar cells

Polymer solar cells are a hot area of research due to both their strong future potential and the significant challenges they pose. Using carefully designed materials and an 'inverted' architecture, a team of scientists has achieved efficiency of 10 percent, bringing these cells close to the threshold of commercial viability.
