Researchers discovered an entirely unexpected atomic arrangement of Gold-144, a molecule-sized nanogold cluster whose structure had been theoretically predicted but never confirmed.

Scientists developed two DNA-based self-assembly approaches for desired nanostructures. The first approach allows the same set of nanoparticles to be connected into a variety of three-dimensional structures; the second facilitates the integration of different nanoparticles and DNA frames into interconnecting modules, expanding the diversity of possible structures. These approaches could enable the rational design of nanomaterials with enhanced or combined optical, electric, and magnetic properties to achieve desired functions.

Scientists have found magnetic excitations in a metallic compound whose main source of magnetism is the orbital movement of its electrons. Their discovery challenges conventional wisdom that these excitations are only found in materials whose magnetism is dominated by the spin of its electrons.

A mathematical approach for studying local magnetic interactions has helped scientists understand the magnetic properties of a material with long-range magnetic order.

By accelerating the formation of the oxygen-oxygen bond in water oxidation, newly developed ruthenium catalysts could drive the reaction needed to efficiently store solar energy in the chemical bonds of clean fuels. Initial electrochemistry studies demonstrated that these catalysts could offer a low-energy pathway to faster water oxidation.

An electron microscopy technique for visualizing how lithium ions migrate at the nanoscale could help improve the performance of lithium-ion batteries.

Scientists at the US Department of Energy's Brookhaven National Laboratory, Cornell University, and collaborators have produced the first direct evidence of a state of electronic matter first predicted by theorists in 1964 -- a 'Cooper pair density wave.' The discovery, described in a paper published online April 13, 2016, in Nature, may provide key insights into the workings of high-temperature superconductors.
