A team of researchers has developed a new microscope that can image the elemental and magnetic properties of a wide range of energy-important materials that are used in devices such as solar cells and solid-state lighting. The imager is based on a technique known as X-ray excited luminescence microscopy (XELM). It was created by hitching a standard optical microscope to a synchrotron X-ray source. Synchrotrons produce X-rays and other forms of electromagnetic radiation by sending electrons...

A key mechanism by which a bacterial pathogen causes the deadly tropical disease melioidosis has been discovered by an international team of scientists. The findings are published today in the journal Science and show how a toxin produced by the bacterium Burkholderia pseudomallei kills cells by preventing protein synthesis. The study, led by the University of Sheffield, paves the way for the development of novel therapies to combat the bacterium which infects millions of people across...

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...

Cornell scientists have surpassed two major milestones toward a novel, exceedingly powerful X-ray source: A record-breaking electron gun emittance and a successfully tested prototype of a superconducting linac cavity. For more than a decade, Cornell scientists have been conducting research and development for an Energy Recovery Linac (ERL) electron accelerator that would produce X-ray beams 1,000 times brighter than any in existence. The university ultimately hopes to use ERL technology...

  A breakthrough in understanding materials for next-generation electronic devices An international team of scientists has developed a novel X-ray technique for imaging atomic displacements in materials with unprecedented accuracy. They have applied their technique to determine how a recently discovered class of exotic materials — multiferroics — can be simultaneously both magnetically and electrically ordered. Multiferroics are also candidate materials for new classes...

Researchers can now see objects more precisely and faster at the nanoscale due to utilising the full color spectrum of synchrotron light, opening the way for faster 3D nanoimaging. This new methodology will provide for enhanced nanoimaging for studying bio samples for medical research, improved drug development and advanced materials for engineering. Using the Advanced Photon Source, a synchrotron facility in Chicago, USA, researchers from the ARC Centre of Excellence for Coherent X-ray...

Researchers have uncovered chemical traces of a pigment, an important component of color, that once formed patterns in the feathers of fossilized birds. The pigment is one of the coloring agents responsible for brown eyes and dark hair in many modern species.  This discovery would have been one of the factors that determined the birds' color patterns, along with structural properties of the birds' feathers and other pigments they ingested as part of their diets. The discovery will help...

An international team including University of Pennsylvania paleontologists is unearthing the appearance of ancient animals by using the world's most powerful X-rays. New research shows how trace metals in fossils can be used to determine the pigmentation patterns of creatures dead for more than a hundred million years. The research was conducted by an international team working with Phillip Manning, an adjunct professor in the School of Arts and Sciences' Department of Earth and Environmental...

Scientists from Finland and France have developed a new synchrotron X-ray technique that may revolutionize the chemical analysis of rare materials like meteoric rock samples or fossils. The results have been published on 29 May 2011 in Nature Materials as an advance online publication. Life, as we know it, is based on the chemistry of carbon and oxygen. The three-dimensional distribution of their abundance and chemical bonds has been difficult to study up to now in samples where these...

Chemical images now much more detailed With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. Carol Hirschmugl, a physicist at the University of Wisconsin-Milwaukee (UWM), led a team of researchers from UWM, the University of Illinois at Urbana-Champaign and University of Illinois at Chicago (UIC) to demonstrate these new capabilities....
