New sensing tech could help detect diseases, fraudulent art, chemical weapons
Discovered in the 1970s, SERS is a sensing technique prized for its ability to identify chemical and biological molecules in a wide range of fields. It has been commercialized, but not widely. That may soon change. An international research team led by University at Buffalo engineers has developed nanotechnology that promises to make SERS simpler and more affordable.

Engineers win grant to make smart clothes for personalized cooling and heating
Imagine a fabric that will keep your body at a comfortable temperature -- regardless of how hot or cold it actually is. That's the goal of an engineering project at the University of California, San Diego, funded with a $2.6M grant from the US Department of Energy's Advanced Research Projects Agency -- Energy. Wearing this smart fabric could potentially reduce heating and air conditioning bills for buildings and homes.

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.

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.
