Researchers combine X-rays and laser light to image sprays

Researchers have developed a new laser-based method that provides an unprecedented view of sprays such as the ones used for liquid fuel combustion in vehicle, ship and plane engines. The technique could provide new insights into these atomizing sprays, which are also used in a variety of industrial processes such as painting and producing food … Read more Researchers combine X-rays and laser light to image sprays

Protein imaging at the speed of life

To study the swiftness of biology – the protein chemistry behind every life function – scientists need to see molecules changing and interacting in unimaginably rapid time increments – trillionths of a second or shorter. Imaging equipment with that kind of speed was finally tested last year at the European X-ray Free-Electron Laser, or EuXFEL. … Read more Protein imaging at the speed of life

Extended X-ray emission around an ultraluminous X-ray pulsar

The accretion of matter onto a compact object (neutron star or black hole) is one of the main and most efficient sources of energy in astrophysics. This energy undergoes transformations up to expressing itself in the form of luminous radiation that we observe as a celestial source or mechanical energy of matter expelled from the … Read more Extended X-ray emission around an ultraluminous X-ray pulsar

Atomic-level imaging could offer roadmap to metals with new properties

High-entropy alloys, which are made from nearly equal parts of several primary metals, could hold great potential for creating materials with superior mechanical properties. But with a practically unlimited number of possible combinations, one challenge for metallurgists is figuring out where to focus their research efforts in a vast, unexplored world of metallic mixtures. A … Read more Atomic-level imaging could offer roadmap to metals with new properties

Scientists watch a black hole shredding a star

A NASA satellite searching space for new planets gave astronomers an unexpected glimpse at a black hole ripping a star to shreds. It is one of the most detailed looks yet at the phenomenon, called a tidal disruption event (or TDE), and the first for NASA’s Transiting Exoplanet Survey Satellite (more commonly called TESS.) The … Read more Scientists watch a black hole shredding a star

How molecular footballs burst in an x-ray laser beam

An international research team has observed in real time how football molecules made of carbon atoms burst in the beam of an X-ray laser. The study shows the temporal course of the bursting process, which takes less than a trillionth of a second, and is important for the analysis of sensitive proteins and other biomolecules, … Read more How molecular footballs burst in an x-ray laser beam

AI uncovers new details about Old Master paintings

Artificial intelligence has been used to analyse high-resolution digital x-ray images of the world famous Ghent Altarpiece, as part of an investigative project led by UCL. The finding is expected to improve our understanding of art masterpieces and provide new opportunities for art investigation, conservation and presentation. Researchers from the National Gallery, Duke University and … Read more AI uncovers new details about Old Master paintings

Atomic ‘Trojan horse’ for a new generation of X-ray lasers

An intense electron beam that could be used in the X-ray lasers of the future has been produced in research led at the University of Strathclyde. The beam was created by the plasma photocathode method, in which electrons were released from neutral atoms inside plasma. This has produced a potentially much brighter, plasma-based electron source which could … Read more Atomic ‘Trojan horse’ for a new generation of X-ray lasers
