The manipulation of atoms has reached a new level: Physicists were able to place 20 single atoms on a fully insulated surface at room temperature to form the smallest 'Swiss cross', thus taking a big step towards next generation atomic-scale storage devices.

Researchers reported the discovery of a new class of biomotor, unique in that it uses a 'revolution without rotation' mechanism. Rotation is the turning of an object around its own axle, as the Earth does every 24 hours. Revolution is the turning of an object around a second object, as the Earth does around the sun.

The model is based on intrinsic electronic characteristics of materials used as battery anodes. These include the material's quantum capacitance (the ability of the material to absorb charge) and the material's absolute Fermi level, which determines how many lithium ions may bond to the electrodes.

Researchers used a technique based on applying short flashes of light to observe and analyse the features of a superconductor at high critical temperature, a material with major prospects for technological applications. In addition to providing an explanation for the peculiar behaviour of the material, the study also opens to the possibility of controlling its characteristics by means of laser pulses.

The new technology is a novel catalyst that performs almost as well as cost-prohibitive platinum for so-called electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen. The technology is also far more efficient than less-expensive catalysts investigated to-date.

Place two large, sturdy logs in a streambed, and they will help guide the water in a par�tic�ular direc�tion. But imagine if the water started mim�ic�king the rigidity of the logs in addi�tion to flowing along them. That's essen�tially what hap�pens in a directed assembly method devel�oped by a researcher at Northeastern University.

Researchers have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It's the first experimental evidence that a boron cage structure - previously only a matter of speculation - does indeed exist.
