Defects in atomically thin semiconductor emit single photons

more »
Researchers have shown that defects on an atomically thin semiconductor can produce light-emitting quantum dots. The quantum dots serve as a source of single photons and could be useful for the integration of quantum photonics with solid-state electronics -- a combination known as integrated photonics.

A milestone towards a higher-energy nuclear physics facility

The first HIE-ISOLDE acceleration module was assembled over the last few months in a new clean room.

CERN's nuclear physics facility ISOLDE will soon be producing radioactive ion beams at higher energies. The purpose of the HIE-ISOLDE (High Intensity and Energy ISOLDE) project, now in the advanced stages of construction at CERN, is to increase the energy and intensity of the ISOLDE beams. The transportation and installation of the first acceleration module on Saturday, 2 May marked an important milestone in the project. Made up of five superconducting accelerating cavities, this sophisticated module required years of development followed by months of assembly in a clean room at CERN. Once connected to the associated infrastructure, it will undergo several weeks of testing before HIE-ISOLDE is commissioned.

The unique ISOLDE facility is dedicated to the production of a large variety of radioactive ion beams for many fields of fundamental and applied research. Each year, its beams are used by around fifty experiments studying a wide range of subjects from the properties of atoms and nuclei to biomedical applications, nuclear astrophysics and solid-state physics. ISOLDE, which celebrated its fiftieth anniversary in 2014, has produced around 700 isotopes of more than 70 elements. HIE-ISOLDE will increase the research opportunities further by producing a greater variety of nuclei.

The new acceleration module will allow HIE-ISOLDE to increase ISOLDE’s beam energy from 3 MeV per nucleon to 4.3 MeV per nucleon by the end of 2015. Ultimately, three further modules will be commissioned, bringing the beam energy from 10 to 15 MeV per nucleon and increasing the beam intensity fourfold.

A Starburst Galaxy - Messier 82 (Cigar Galaxy) Sticker

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


tagged with: envelope sealers, galaxies and stars, hubble, messier 82, cigar galaxy, active galaxies, starburst galaxy, nasa esa, sbglxymet

Galaxies, Stars and Nebulae series This mosaic image of the magnificent starburst galaxy, Messier 82 (aka Cigar Galaxy) is a really sharp wide-angle view of M82. It is a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions where young stars are being born 10 times faster than they are inside in our Milky Way Galaxy.

Multicolor meta-hologram produces light across entire visible spectrum

more »
(Phys.org)—There are many different ways to generate a hologram, each with its own advantages and disadvantages. Trying to maximize the advantages, researchers in a new study have designed a hologram made of a metamaterial consisting of aluminum nanorods that can produce light across the entire visible spectrum, and do so in a way that yields brighter images than other methods.

Keyhole Nebula and Digitus Impudicus Stickers

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


tagged with: kndigimp, envelope sealers, galaxies and stars, keyhole nebula, carina nebula, massive stars, hubble space telescope, digitus impudicus, complex structure

Galaxies, Stars and Nebulae series Details of a mysterious, complex structure within the Carina Nebula (NGC 3372) are revealed by this image of the 'Keyhole Nebula, ' obtained with the Hubble Space Telescope. The picture is a montage assembled from four different April 1999 telescope pointings with Hubble's Wide Field Planetary Camera 2, which used six different colour filters. The picture is dominated by a large, approximately circular feature, which is part of the Keyhole Nebula, named in the 19th century by Sir John Herschel. This region, about 8000 light-years from Earth, is located adjacent to the famous explosive variable star Eta Carinae, which lies just outside the field of view toward the upper right. The Carina Nebula also contains several other stars that are among the hottest and most massive known, each about 10 times as hot, and 100 times as massive, as our Sun.
