Multilayer Laue Lenses Enable Studies of Nanostructures with Ultra-high Resolution
Microscopes have been a centerpiece of experimental science since at least the 16th century, providing a window into the material world at extraordinarily small scales. As the structures examined decrease in size - some measuring just billionths of a meter - capturing an x-ray image at high spatial resolution while retaining sufficient imaging contrast becomes more difficult. more
High-energy X-rays: Measuring the Structure of Nanomaterials under Extremely High Pressures
A team of researchers has made a major breakthrough in measuring the structure of nanomaterials under extremely high pressures. For the first time, they developed a way to get around the severe distortions of high-energy X-ray beams that are used to image the structure of a gold nanocrystal. The technique, described in Nature Communications, could lead to advancements of new nanomaterials created under high pressures and a greater understanding of what is happening in planetary interiors.more
Ptychography-Tomography: 3D Visualisation of Anti-Corrosion Paint
Researchers at the London Centre for Nanotechnology (LCN) have revealed detailed 3D images of an important industrial coating that is used to reduce corrosion of ship hulls. The work, carried out in collaboration with international paints and coatings company Akzo-Nobel, allows the automatic identification of aluminium, talc, pigment and remaining filler components in the image, based solely on X-ray refractive data.more
X-Ray Bragg Projection Ptychography: Imaging of Strain at the Nanoscale
The theoretical and experimental framework of a new coherent diffraction strain imaging approach was developed in the Center for Nanoscale Materials' X-Ray Microscopy Group in collaboration with Argonne's Materials Science Division, together with users from IBM. moreAug. 22, 2012New 3-D Visualization Technology Using Lensless X-ray Coherent Diffraction Imaging
For the first time scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample. This new technique expands the range of X-ray research possible for biology and many aspects of nanotechnology, particularly nanofilms, photonics, and micro- and nano-electronics. This new technique also reduces "guesswork" by eliminating the need for modeling-dependent structural simulation often used in X-ray analysis.more
Coherent Diffraction Imaging of Gold Nanocrystals in 3D
A new advance in X-ray imaging has revealed the dramatic three-dimensional shape of gold nanocrystals, and is likely to shine a light on the structure of other nano-scale materials. Described in Nature Communications, the new technique improves the quality of nanomaterial images, made using X-ray diffraction, by accurately correcting distortions in the X-ray light. moreApr. 02, 2012Bruker Acquires SkyScan
Bruker Corporation announced that it has acquired all of the shares of SkyScan N.V., a scientific instruments company located near Antwerp, Belgium. Financial details were not disclosed. For the remainder for 2012, the acquisition of SkyScan is expected to add approximately US-$ 13 million to Bruker's revenue and to be accretive to EPS by about US-$ 0.01. SkyScan's revenue is derived approximately 50% from materials science and 50% from life science and preclinical imaging applications. more
Imaging Proteins Using X-Ray Pulses
Using a unique facility in the US, researchers at the University of Gothenburg have found a more effective way of imaging proteins. The next step is to film how proteins work - at molecular level.Mapping the structure of proteins and the work they do in cells could be the key to cures for everything from cancer to malaria. Last year Richard Neutze, professor of biochemistry at the University of Gothenburg, and his research group were among the first in the world to image proteins using very short and intensive X-ray pulses. more
Positioning Systems for Vacuum Applications
PI miCos - Specialist for Precise Positioning Systems in a Vacuum: A wide variety of applications in microscopy or optical measurement technology require a sample or an optical element to be positioned in a vacuum of up to 10-11 hPa. One approach consists of positioners with vacuum stepper motors - from simple linear or rotation units to Hexapods and spacefabs that allow six-axis positioning in the smallest spaces with high accuracies of a few micrometers. more
Innovativ X-Ray Camera for European XFEL
Designed to record bursts of images at an unprecedented speed of 4.5 million frames per second, an innovative X-ray camera being built with STFC's engineering expertise will help a major new research facility shed light on the structure of matter. The device will be delivered to the European XFEL (X-ray Free-Electron Laser) next year and will contribute to drug discovery and other vital research once this facility starts operating in 2015. more- Legal
