Astronomers observe distant galaxy powered by primordial cosmic fuel

more »

(Phys.org) —Astronomers have detected cold streams of primordial hydrogen, vestigial matter left over from the Big Bang, fueling a distant star-forming galaxy in the early Universe. Profuse flows of gas onto galaxies are believed to be crucial for explaining an era 10 billion years ago, when galaxies were copiously forming stars. To make this discovery, the astronomers – led by Neil Crighton of the Max Planck Institute for Astronomy and Swinburne University – made use of a cosmic coincidence: a bright, distant quasar acting as a "cosmic lighthouse" illuminates the gas flow from behind. The results were published October 2 in the Astrophysical Journal Letters.

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

(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.

Super-earth or mini-Neptune? Telling habitable worlds apart from lifeless gas giants

more »

Perhaps the most intriguing exoplanets found so far are those bigger than our rocky, oceanic Earth but smaller than cold, gas-shrouded Uranus and Neptune. This mysterious class of in-between planets—alternatively dubbed super-Earths or mini-Neptunes—confounds scientists because nothing like them exists as a basis for comparison in our solar system.

The intergalactic medium in the young universe

more »

(Phys.org) —In its earliest years, the universe was so hot that electrons and protons could not bind together in neutral atoms: all of the gas in the cosmos was ionized. Then, after 380,000 years of expansion, the universe cooled enough for hydrogen atoms and some helium (about 25%) to form. Much later in cosmic history—the precise dating is an active area of current research but perhaps after a few hundred million years—the first generation of stars emerged from the vast expanses of atomic gas, and these stars emitted enough strong ultraviolet light to re-ionize the neutral hydrogen in their vicinity. As the universe continued to expand and evolve, newer generations of stars continued to re-ionize the hydrogen until at some time most gas between galaxies (the intergalactic medium) was ionized once again. The epoch of re-ionization is an important diagnostic tool because it traces when the first generations of stars were being made, and it provides crucial details about the early evolution of the universe.

Improving lithium-ion batteries with nanoscale research

more »

New research led by an electrical engineer at the University of California, San Diego is aimed at improving lithium (Li) ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers have presented nanowires that block diffusion of lithium across the wire's silicon surface and promote layer-by-layer axial lithiation of the nanowire's germanium core.

Building bridges between nanowires

more »

Place a layer of gold only a few atoms high on a surface bed of germanium, apply heat to it, and wires will form of themselves. Gold-induced wires is what Mocking prefers to call them. Not 'gold wires', as the wires are not made solely out of gold atoms but also contain germanium. They are no more than a few atoms in height and are separated by no more than 1.6 nanometres (a nanometre is one millionth of a millimetre). Nanotechnologists bridge this small 'gap' with a copper-phthalocyanine molecule. A perfect fit. This molecule was found to be able to rotate if the electrons coursing towards it possess sufficient energy, allowing it to function as a switch. What's more: the copper atom of this molecule floats in the vacuum above the gap - fully detached. This might allow researchers to identify new properties the nanowires may possess.

Nanocrystal catalyst transforms impure hydrogen into electricity

more »

(Phys.org) —The quest to harness hydrogen as the clean-burning fuel of the future demands the perfect catalysts—nanoscale machines that enhance chemical reactions. Scientists must tweak atomic structures to achieve an optimum balance of reactivity, durability, and industrial-scale synthesis. In an emerging catalysis frontier, scientists also seek nanoparticles tolerant to carbon monoxide, a poisoning impurity in hydrogen derived from natural gas. This impure fuel—40 percent less expensive than the pure hydrogen produced from water—remains largely untapped.

Smaller than small: Why we measure the space between atoms

more »

We study the movement of incredibly small things. How small is small? Think smaller than "nano." Think smaller than atoms themselves. We measure the infinitesimally small shifts in the positions of atoms to electrical forces. Measuring small is challenging, but rewarding. By measuring things this small, we unlock hidden secrets that will advance a host of different electronic devices.

The Cat's Eye Nebula or NGC 6543, is a planetary nebula in the constellation of Draco. Structurally, it is one of the most complex nebulae known, with high-resolution Hubble Space Telescope observations revealing remarkable structures such as knots, jets, bubbles and sinewy arc-like features. In the center of the Cat's Eye there is a bright and hot star; around 1000 years ago this star lost its outer envelope, producing the nebula. - Wikipedia.org. Image by NASA.

Galaxies, Stars and Nebulae series A colourful star-forming region is featured in this stunning image of NGC 2467 located in the southern constellation of Puppis (The Stern). Looking like a roiling cauldron of some exotic cosmic brew, huge clouds of gas and dust are sprinkled with bright blue, hot young stars. Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing gas. Like the familiar Orion Nebula, NGC 2467 is a huge cloud of gas, mostly hydrogen, that serves as an incubator for new stars. Some of these youthful stars have emerged from the dense clouds where they were born and now shine brightly, hot and blue in this picture, but many others remain hidden.

ATLAS undergoes some delicate gymnastics




The "big opening" of ATLAS, showing the endcap calorimeter (right) and toroid magnet coils (left) (Image: B Di Girolamo)




The LHC’s first long shutdown has provided the opportunity for a major programme of consolidation and improvements on the ATLAS detector. One of the biggest interventions concerns the insertion of a fourth, innermost layer for the pixel detector. This has required the so-called “big opening” of ATLAS in which one of the small muon wheels is lifted to the surface. The pixel detector itself has also been raised to the surface for repair work. Other activities include improvements to the muon chambers and calorimeters, as well as a great deal of consolidation work on infrastructure.
