Nature Physics
Physicists precisely measure interaction between atoms and carbon surfaces
Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon surface used in battery electrodes and air filters -- key information for improving those technologies.

Experiment confirms quantum theory weirdness: ANU media release
The bizarre nature of reality as laid out by quantum theory has survived another test, with scientists performing a famous experiment and proving that reality does not exist until it is measured. Physicists at The Australian National University have conducted John Wheeler's delayed-choice thought experiment, which involves a moving object that is given the choice to act like a particle or a wave. The group reversed Wheeler's original experiment, and used helium atoms scattered by light.

New technique speeds nanoMRI imaging
NanoMRI is a scanning technique that produces nondestructive, high-resolution 3D images of nanoscale objects, and promises to become a powerful tool. Producing images with near-atomic resolution, however, is difficult and time-consuming. Striving to overcome this limitation, researchers have developed a parallel measurement technique, which they report in Applied Physics Letters. Information that normally would be measured sequentially -- one bit after another -- can now be measured at the same time with a single detector.

One step closer to a single-molecule device
Columbia Engineering professor Latha Venkataraman has designed a new technique to create a single-molecule diode, and, in doing so, she has developed molecular diodes that perform 50 times better than all prior designs. Venkataraman's group is the first to develop a single-molecule diode that may have real-world technological applications for nanoscale devices.

Engineering phase changes in nanoparticle arrays
Scientists at the US Department of Energy's Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be switched on demand. In a paper appearing in Nature Materials, they describe a way to selectively rearrange the nanoparticles in three-dimensional arrays to produce different configurations, or phases, from the same nano-components.

DNA double helix does double duty in assembling arrays of nanoparticles
In a new twist on the use of DNA in nanoscale construction, scientists at the US Department of Energy's Brookhaven National Laboratory and collaborators put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.

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.

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.
