Lunar pits could shelter astronauts, reveal details of how 'man in the moon' formed

July 17, 2014 7:04 pm | by EurekAlert! | Comments

While the moon's surface is battered by millions of craters, it also has over 200 holes – steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft.

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

July 17, 2014 6:40 pm | by EurekAlert! | Comments

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 less than ~600 nm for red light). A standard optical microscope acts as a "nanocamera" whereas the pBNAs are the analogous film.

Future electronics may depend on lasers, not quartz

July 17, 2014 6:21 pm | by EurekAlert! | Comments

Researchers in the laboratory of Kerry Vahala, the Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics at Caltech, have developed a method to stabilize microwave signals in the range of gigahertz, or billions of cycles per second—using a pair of laser beams as the reference, in lieu of a crystal.

First ab initio method for characterizing hot carriers

July 17, 2014 2:16 pm | by EurekAlert! | Comments

Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed the first ab initio method – meaning a theoretical model free of adjustable or empirical parameters – for characterizing the properties of "hot carriers" in semiconductors. Hot carriers are electrical charge carriers - electrons and holes – with significantly higher energy than charge carriers at thermal equilibrium.

Plasmon-enhanced Polarization-selective filter

July 17, 2014 1:54 pm | by EurekAlert! | Comments

As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light. A common polarizer is also called half-wave plate, which constructed out of a birefringent material (such as quartz or mica).
