Simulations help researchers decide which technology would make a better solar collector, quantum dot or nanowire

more »

A trio of researchers at North Dakota State University and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels—quantum dots or nanowires.

Researchers create image of weak hydrogen bond using AFM

more »

(Phys.org) —Researchers at China's National Center for Nanoscience and Technology and Renmin University have used Atomic Force Microscopy (AFM) to create an image of the weak hydrogen bonds present in a molecule. In their paper published in the journal Science, the team describes how they used the non-contact form of AFM to capture an image of weak hydrogen bonds in a 8-hydroxyquinoline molecule (8hq).

New kind of 'X-ray/CT vision' reveals objects' internal nanoscale structure, chemistry

more »

(Phys.org) —Nanomaterials made of particles with dimensions measured in billionths of a meter hold enormous promise for creating more efficient batteries, fuel cells, catalysts, and drug-delivery systems. Seeing how the nanostructured materials inside these devices evolve and interact as they operate is essential to gain insight into ways to optimize performance. But most studies have looked at idealized samples of isolated components, not as they function in operating devices.

Engineers invent programming language to build synthetic DNA

more »

Similar to using Python or Java to write code for a computer, chemists soon could be able to use a structured set of instructions to "program" how DNA molecules interact in a test tube or cell.

Enlarged Region of The Omega Nebula Room Graphic

Here's a great wall decal featuring a beautiful image from deep space

what do you think of this one? I bumped into it and thought it was cool. By HightonRidley,

Enlarged Region of The Omega Nebula Room Graphic

tagged with: stars, galaxies, astronomy, universe, outer space, eroton, galaxy, star, wall decal, galaxies stars, gas clouds, star forming activity, green hydrogen, blue oxygen, omega nebula m17, ultraviolet radiation, young massive stars, red sulpher

Galaxies, Stars and Nebulae series Like the fury of a raging sea, this bubbly ocean of glowing hydrogen, oxygen, and sulphur gas lies in the extremely massive and luminous molecular nebula Messier 17.
This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation.
Ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds and the warmed surfaces glow orange and red. The intense heat and pressure causes some material to stream away from the surface, creating the glowing veil of even hotter green-coloured gas that masks background structures. The colours in the image represent various gases. Red represents sulphur; green, hydrogen; and blue, oxygen.

Stellar Nursery R136 in the Tarantula Nebula Stickers

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

Stellar Nursery R136 in the Tarantula Nebula Stickers

tagged with: stars, galaxies, astronomy, galaxy, envelope sealers, dorneblmc, stellar nursery, r136, 30 doradus nebula, massive stars, large magellanic cloud, star cluster, amazing hubble images, tarantula nebula

Galaxies, Stars and Nebulae series Hundreds of brilliant blue stars wreathed by warm, glowing clouds in appear in this the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus (or Tarantula) Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way.
There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years. The image, taken in ultraviolet, visible, and red light by Hubble's Wide Field Camera 3, spans about 100 light-years.
The movement of the LMC around the Milky Way may have triggered the massive cluster's formation in several ways. The gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have compressed gas in the LMC. Also, the pressure resulting from the LMC plowing through the Milky Way's halo may have compressed gas in the satellite. The cluster is a rare, nearby example of the many super star clusters that formed in the distant, early universe, when star birth and galaxy interactions were more frequent.
The LMC is located 170,000 light-years away and is a member of the Local Group of Galaxies, which also includes the Milky Way. The Hubble observations were taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen.
