2-D semiconductor comes clean: Performance dramatically improved

more »
Scientists have dramatically improved the performance of graphene by encapsulating it in boron nitride. They’ve now shown they can similarly improve the performance of another 2D material, molybdenum disulfide (MoS2. Their findings provide a demonstration of how to study all 2D materials and hold great promise for a broad range of applications including high-performance electronics, detection and emission of light, and chemical/bio-sensing.

Is the universe a hologram?

more »
The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange curved spaces. New results suggest that the holographic principle also holds in flat spaces. Our own universe could in fact be two dimensional and only appear three dimensional -- just like a hologram.

Monogram - Eagle Nebula, Pillars of Creation Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space

Monogram - Eagle Nebula, Pillars of Creation Stickers

Galaxies, Stars and Nebulae series A breathtaking outer space picture showing a spectacular three-colour composite mosaic image of the Eagle Nebula (Messier 16, or NGC 6611). It's based on images obtained with the Wide-Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory.

At the centre, the so-called “Pillars of Creation” can be seen and this wide-field image shows not only the central pillars, but also several others in the same star-forming region, as well as a huge number of stars in front of, in, or behind the Eagle Nebula.

The cluster of bright stars to the upper right is NGC 6611, home to the massive and hot stars that illuminate the pillars. The “Spire” - another large pillar - is in the middle left of the image.

Highly conductive germanium nanowires made by a simple, one-step process

more »
For the first time, germanium nanowires have been deposited on indium tin oxide substrate by a simple, one-step process called electrodeposition. The nanowires produced by this method have outstanding electronic properties and can be used as high-capacity anode material for lithium-ion batteries; however, the nanowires were previously too expensive and difficult to produce. This process may resolve the cost issue.

Researchers take a step towards development of optical single-phonon detector

more »
(Phys.org)—A team of researchers with members from institutions in the U.S. and Austria has succeeded in building a device that shows a clear step towards the development of an optical single-phonon detector. In their paper published in the journal Nature, the team describes their device and to what purposes it might be put. Ivan Favero with the University of Paris, offers a News & Views research perspective on the work done by the team and why it represents a big step forward in optomechanics.

Turbulent Star-Birth Region Selection Case For The iPad Mini

tagged with: hubble, nasa, stars, star, galaxy, galaxies, space, astronomy, telescope, beautiful, photos, nebula, nature, landscapes

In commemoration of NASA's Hubble Space Telescope completing its 100,000th orbit in its 18th year of exploration and discovery, scientists at the Space Telescope Science Institute in Baltimore, Md., have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal. Hubble peered into a small portion of the nebula near the star cluster NGC 2074 (upper, left). The region is a firestorm of raw stellar creation, perhaps triggered by a nearby supernova explosion. It lies about 170,000 light-years away near the Tarantula nebula, one of the most active star-forming regions in our Local Group of galaxies. The three-dimensional-looking image reveals dramatic ridges and valleys of dust, serpent-head "pillars of creation," and gaseous filaments glowing fiercely under torrential ultraviolet radiation. The region is on the edge of a dark molecular cloud that is an incubator for the birth of new stars. The high-energy radiation blazing out from clusters of hot young stars already born in NGC 2074 is sculpting the wall of the nebula by slowly eroding it away. Another young cluster may be hidden beneath a circle of brilliant blue gas at center, bottom. In this approximately 100-light-year-wide fantasy-like landscape, dark towers of dust rise above a glowing wall of gases on the surface of the molecular cloud. The seahorse-shaped pillar at lower, right is approximately 20 light-years long, roughly four times the distance between our Sun and the nearest star, Alpha Centauri. The region is in the Large Magellanic Cloud (LMC), a satellite of our Milky Way galaxy. It is a fascinating laboratory for observing star-formation regions and their evolution. Dwarf galaxies like the LMC are considered to be the primitive building blocks of larger galaxies. This representative color image was taken on August 10, 2008, with Hubble's Wide Field Planetary Camera 2. Red shows emission from sulfur atoms, green from glowing hydrogen, and blue from glowing oxygen. Source: NASA.
