New laser for computer chips
Scientists from Forschungszentrum Juelich and the Paul Scherrer Institute in Switzerland in cooperation with international partners have presented the first semiconductor consisting solely of elements of main group IV. As a consequence, the germanium-tin laser can be applied directly onto a silicon chip and thus creates a new basis for transmitting data on computer chips via light: this transfer is faster than is possible with copper wires and requires only a fraction of the energy.

Gold nanoparticles show promise for early detection of heart attacks
A novel colloidal gold test strip is demonstrating great potential for early detection of certain heart attacks. Researchers are developing the strip to test for cardiac troponin I (cTn-I); its level is several thousand times higher in patients experiencing myochardial infarctions. The new strip uses microplasma-generated gold nanoparticles. Compared to AuNPs produced by traditional chemical methods, the surfaces of thesenanoparticles attract more antibodies, which results in significantly higher detection sensitivity.

Rapid journey through a crystal lattice
How fast do electrons whiz through the atomic layers of a crystal lattice? A team of scientists led by researchers from the Technische Universitat München joined by colleagues from the Max Planck Institute of Quantum Optics, the Ludwig-Maximilians-Universitat Munich and the Technical University of Vienna has now investigated this fundamental question. The researchers measured the time electrons needed to travel through a film consisting of a few layers a of magnesium atoms.

Story tips from the Department of Energy's Oak Ridge National Laboratory, January 2015
While researchers in Oak Ridge National Laboratory's buildings group focus on increasing energy efficiency using new foam insulation panels, the nanophase materials sector experiments with catalyst performance, revealing an oxidation discovery that could help reduce vehicle emissions. Additionally, Oak Ridge National Laboratory researchers aim to reduce the size, weight and power for some particle accelerators with development of a new voltage supply. And by using water and nano-sized particles isolated from trees and plants, scientists explore low-cost and nontoxic metal oxides.

Moving origami techniques forward for self-folding 3-D structures
Though the past 15 years have seen an exciting run of creative scientific advances in fabricating three-dimensional (3-D) structures by self-folding of 2-D sheets, the complexity of structures achieved to date falls far short of what can easily be folded by hand using paper, says polymer scientist Ryan Hayward at the University of Massachusetts Amherst. Now he has developed an approach that could open the door to a new wave of discoveries.
