Laser pulses lasting less than 150 attoseconds have been used to observe, in real time, the motion of electrons in the outermost (“valence”) shell of ionised krypton atoms. This technical achievement, reported in Nature 466(7307), 739–742, lays the groundwork for observations in more complex systems, which should allow a detailed examination of the fundamental processes underlying the making and breaking of chemical bonds.
Microscopy with atomic resolution could be useful in the determining the structure of some unknown organic compounds, such as medicinally important natural products, according to a study online in Nature Chemistry. This method could avoid the lengthy and expensive process of trying to synthesise the compound and then compare its structure with that of the natural one, which is necessary in some cases.
A new technique for following chemical reactions in real time makes a virtue of necessity, by using the radiation from non-reacting molecules as part of the detection method. As reported in Nature, this implementation of “high-harmonic interferometry” can be used to monitor both molecular structure and electron dynamics, the latter with attosecond time resolution.
The ABS Trust invites UK-based university students undertaking spectroscopy research or utilising spectroscopy as a major component of their research to apply for a bursary award to attend a recognised scientific meeting to present an oral or poster presentation or to visit a place of learning to advance their spectroscopy knowledge and understanding.
How did Leonardo Da Vinci manage to paint such perfect faces? XRF analysis has shown the composition and thickness of each layer of material laid down by the painter. The results reveal that, in the case of glazes, thin layers of 1–2 µm have been applied.
The new Jean Jeener Bio-NMR Centre at the VIB Department of Molecular and Cellular Interactions, Vrije Universiteit Brussel, has already played a role in a scientific breakthrough that has been published Cell. Thanks to NMR, it is possible to determine the dynamic structure of proteins, and it was used to find out how the activity of certain proteins involved in the stress physiology of bacteria is regulated.
Since 2004 the Büchi Young Scientists NIRAward has been given to young scientists who worked during their diploma or doctoral thesis in the field of near infrared spectroscopy and achieved outstanding results. In the past many excellent scientists from NIR research groups all over the world have received this award.
APPELS, differentially pumped Ambient Pressure PhotoElectron Lens System for photoemission studies, is one of four inventions from the US Department of Energy’s Lawrence Berkeley National Laboratory which have been recognised with the R&D 100 award for 2010 from R&D Magazine, which recognises the 100 most significant proven technological advances of the year.
The potential impact of lipid research has been increasingly realised both in disease treatment and prevention. Recent advances in soft ionisation mass spectrometry (MS) such as electrospray ionisation (ESI) have permitted parallel monitoring of several hundreds of lipids in a single experiment and thus facilitated lipidomics level studies. These advances, however, pose a greater challenge for bioinformaticians to handle massive amounts of information-rich MS data from modern analytical instruments in order to understand complex functions of lipids.
