Basel physicists develop efficient method of signal transmission from nanocomponents
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal Nature Communications together with their colleagues from ETH Zurich.

Visualizing how radiation bombardment boosts superconductivity
Study shows how heavy-ion induced atomic-scale defects in iron-based superconductors 'pin' potentially disruptive quantum vortices, enabling high currents to flow unimpeded. The study opens a new way forward for designing and understanding superconductors that can operate in demanding high-current, high magnetic field applications, such as zero-energy-loss power transmission lines and energy-generating turbines.

Turn that defect upside down
Most people see defects as flaws. A few Michigan Technological University researchers, however, see them as opportunities. Twin boundaries -- which are small, symmetrical defects in materials -- may present an opportunity to improve lithium-ion batteries.

SPIE Spotlights e-book series launches, offering short tutorials in optics and photonics
SPIE Spotlights, a new peer-reviewed e-book series from SPIE, the international society for optics and photonics, has launched with tutorials on image resolution, fiber optics, and logistics of setting up a laser lab. The new series fills a gap between longer works and single papers, and provides an accessible resource for professionals throughout the field.

Researchers develop new way to manufacture nanofibers
Researchers at the University of Georgia have developed an inexpensive way to manufacture nanofibers. The new method, dubbed 'magnetospinning,' provides a very simple, scalable and safe means for producing very large quantities of nanofibers that can be embedded with a multitude of materials, including live cells and drugs.

Defects can 'Hulk-up' materials

Nature inspires first artificial molecular pump
Using nature for inspiration, Northwestern University scientists are the first to develop an entirely artificial molecular pump, in which molecules pump other molecules. The machine mimics the pumping mechanism of proteins that move small molecules around living cells to metabolize and store energy from food. The pump draws its power from chemical reactions, driving molecules step-by-step from a low-energy state to a high-energy state. The pump one day might be used to power other molecular machines, such as artificial muscles.

Tunable liquid metal antennas
Researchers have held tremendous interest in liquid metal electronics for many years, but a significant and unfortunate drawback slowing the advance of such devices is that they tend to require external pumps that can't be easily integrated into electronic systems. So a team of North Carolina State University researchers set out to create a reconfigurable liquid metal antenna controlled by voltage only, which they describe this week in the Journal of Applied Physics.

Pactamycin analogs offer new, gentler approach to cancer treatment
Researchers are pursuing a new concept in treatment of cancer, by using two promising 'analogs' of an old compound that was once studied as a potent anti-tumor agent, but long ago abandoned because it was too toxic. The idea is not to kill cancer cells, but rather to put them to sleep - lessening problems with resistance to chemotherapeutic drugs, and also the side effects of chemotherapy.

Efficiency record for black silicon solar cells jumps to 22.1 percent
The researchers from Finland's Aalto University and Universitat Politècnica de Catalunya have obtained the record-breaking efficiency of 22.1 percent on nanostructured silicon solar cells as certified by Fraunhofer ISE CalLab. An almost 4 percent absolute increase to their previous record is achieved by applying a thin passivating film on the nanostructures by Atomic Layer Deposition, and by integrating all metal contacts on the back side of the cell.

Gel filled with nanosponges cleans up MRSA infections
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This 'nanosponge-hydrogel' minimized the growth of skin lesions on mice infected with MRSA -- without the use of antibiotics. The researchers recently published their findings online in dvanced Materials.

Random nanowire configurations increase conductivity over heavily ordered configurations
Researchers at Lehigh University have identified for the first time that a performance gain in the electrical conductivity of random metal nanowire networks can be achieved by slightly restricting nanowire orientation. The most surprising result of the study is that heavily ordered configurations do not outperform configurations with some degree of randomness; randomness in the case of metal nanowire orientations acts to increase conductivity.

New nanomaterials inspired by bird feathers play with light to create color
Inspired by the way iridescent bird feathers play with light, scientists have created thin films of material in a wide range of pure colors -- from red to green -- with hues determined by physical structure rather than pigments. Chemists synthesized and assembled nanoparticles of a synthetic version of melanin to mimic the natural structures found in bird feathers.
