Tiny laser sensor heightens bomb detection sensitivity

24-07-2014

New technology under development at the University of California, Berkeley, could soon give bomb-sniffing dogs some serious competition. A team of researchers led by Xiang Zhang, UC Berkeley professor of mechanical engineering, has found a way to dramatically increase the sensitivity of a ...

Highly charged ions

Multiply-ionized atoms for clocks, qubits, and constants

24-07-2014

The world is mostly neutral. That is, most of the atoms in our environment are electrically neutral. The number of electrons in the outer parts of atoms equals the number of protons at the centers of atoms. As one or more electrons are plucked away from the atoms, the remaining electrons feel a ...

Rice nanophotonics experts create powerful molecular sensor

Sensor amplifies optical signature of single molecules about 100 billion times

23-07-2014

Nanophotonics experts at Rice University have created a unique sensor that amplifies the optical signature of molecules by about 100 billion times. Newly published tests found the device could accurately identify the composition and structure of individual molecules containing fewer than 20 ...

'Nanocamera' takes pictures at distances smaller than light's own wavelength

How is it possible to record optically encoded information for distances smaller than the wavelength of light?

22-07-2014

Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances ...

Fundamental chemistry findings could help extend Moore's Law

17-07-2014

Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process ...

NMR under pressure: Reproducing deep-Earth chemistry

16-07-2014

A new pressure cell invented by UC Davis researchers makes it possible to simulate chemical reactions deep in the Earth's crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid at pressures up to 20 kiloBar. "NMR is our ...
