Helmholtz-Zentrum Dresden-Rossendorf A formation mechanism of nanocrystalline cerium dioxide (CeO2), a versatile nanomaterial, has been unveiled by scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the University of New South Wales in Sydney, Australia. The research results were published in the scientific journal Chemistry – A European Journal. This finding potentially simplifies and alleviates the existing synthetic processes of nanocrystalline CeO2 production....

X-rays Help Understand How Mechanical Action May Lead To Greener Chemistry

European Synchrotron Radiation Facility Solvents are omnipresent in the chemical industry, and are a major environmental and safety concern. Therefore the large interest in mechanochemistry: an energy-efficient alternative that avoids using bulk solvents and uses high-frequency milling to drive reactions. Milling is achieved by the intense impact of steel balls in a rapidly moving jar, which hinders the direct observation of underlying chemistry. Scientists have now for the first time...

ESRF inaugurates unique new X-ray facility Scientists will soon be exploring matter at temperatures and pressures so extreme it can only be produced for microseconds using powerful pulsed lasers. Matter in such states is present in the Earth's liquid iron core, 2500 kilometers beneath the surface, and also in elusive "warm dense matter" inside large planets like Jupiter. A new X-ray beamline ID24 at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, allows a new...

Producing tightly focused beams of high energy X-rays, to examine everything from molecular structures to the integrity of aircraft wings, could become simpler and cheaper according to new research. Today, in Nature Physics, researchers from Imperial College London, the University of Michigan and Instituto Superior T©chnico Lisbon describe a tabletop instrument that produces synchrotron X-rays, whose energy and quality rivals that produced by some of the largest X-ray facilities in the...

For the first time scientists have been able to watch nanoparticles grow from the earliest stages of their formation. Nanoparticles are the foundation of nanotechnology and their performance depends on their structure, composition, and size. Researchers will now be able to develop ways to control conditions under which they are grown. The breakthrough will affect a wide range of applications including solar-cell technology and chemical and biological sensors. The research is published in...

Scientists for the first time have dived into the effect that an intense X-ray free electron laser (XFEL) has on materials. Using the Linac Coherent Light Source (LCLS) facility at the SLAC National Accelerator Laboratory, Lawrence Livermore scientists probed nitrogen gas at X-ray energies of up to 8 keV (kiloelectronvolts), the highest X-ray energy ever used at an XFEL, to see how it behaved when the laser hit it. The photoluminescence-based pulse-energy detector allowed the team to study...

A massive old star is about to die a spectacular death. As its nuclear fuel runs out, it begins to collapse under its own tremendous weight. The crushing pressure inside the star skyrockets, triggering new nuclear reactions, setting the stage for a terrifying blast. And then... nothing happens. At least that's what supercomputers have been telling astrophysicists for decades. Many of the best computer models of supernova explosions fail to produce an explosion. Instead, according to the...

Researchers say a new facility opening later this year at Britain's Diamond Light Source synchrotron may revolutionize science. Officials said the powerful new experimental station called the Joint Engineering, Environmental and Processing beamline will carry out experiments in a variety of scientific areas, including biology and physical and chemical science. The versatility of JEEP will open up exciting new opportunities in many fields of science due to its extremely high flux, high energy...

A new facility opening later this year at the Diamond synchrotron is set to revolutionize world heritage science. A new research platform soon to be available at the leading UK science facility, Diamond Light Source, will help uncover ancient secrets that have been locked away for centuries. For the first time ever, cultural heritage scientists will be able to scan and image large relics and artifacts up to two tons in weight in incredible precision. They will no longer be restricted to...


Word of the Day
sough
  • A murmuring sound; a rushing or whistling sound, like that of the wind; a deep sigh.
  • A gentle breeze; a waft; a breath.
  • Any rumor that engages general attention.
  • A cant or whining mode of speaking, especially in preaching or praying; the chant or recitative characteristic of the old Presbyterians in Scotland.
  • To make a rushing, whistling, or sighing sound; emit a hollow murmur; murmur or sigh like the wind.
  • To breathe in or as in sleep.
  • To utter in a whining or monotonous tone.
According to the OED, from the 16th century, this word is 'almost exclusively Scots and northern dialect until adopted in general literary use in the 19th.'
