For the first time ever, physicists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in proving that an optical system can be ‘invisible' from one side and act like a mirror from the other side. The study has been published in Nature. moreAug. 23, 2012
Detailed molecular-scale measurements of a chemical reaction accelerated by sunlight have been made for the first time ever. Chemists at Utrecht University (The Netherlands) and the Friedrich Schiller University Jena (Germany) have set up a special microscope to simultaneously take part in and observe the catalysed chemical reaction. The results were published in Nature Nanotechnology. moreAug. 22, 2012
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. moreAug. 21, 2012
Researchers at King's College London, in collaboration with European research institutes ICFO (Barcelona) and AMOLF (Amsterdam), have succeeded in mapping how light behaves in complex photonic materials inspired by nature, like iridescent butterfly wings. Scientists have broken the limit of light resolution at the nanoscale and delivered a fundamental insight into how light and matter interact, which could lead to the development of enhanced bio-sensors for healthcare and more efficient solar cells and displays. moreAug. 21, 2012
X-ray free-electron lasers (XFELs) are new, large-scale research facilities that open up completely new insights in the nanoworld. With X-ray flashes of unprecedented brightness and shortness, the XFELs allow direct observation of single molecules, atoms, and even chemical reactions. moreAug. 20, 2012
A new super-resolution microscope, combining laser optics and high-resolution imaging, will give scientists a better way to study the chemical properties of surfaces, ranging from plastic and metal to cells and water.
The microscope will be built at the University of Houston thanks to a three-year, US-$-1 million grant from the W. M. Keck Foundation to Steven Baldelli, an associate professor of chemistry at UH. Baldelli is collaborating with Kevin Kelly, an associate professor of electrical and computer engineering at Rice University. moreAug. 16, 2012
Virtual Nanoscopy: Just as users of Google Earth can zoom in from space to a view of their own backyard, researchers can now navigate biological tissues from a whole embryo down to its subcellular structures thanks to recent advances in electron microscopy and image processing, as described in The Journal of Cell Biology (JCB). moreAug. 09, 2012
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. more
