Honouring the inventor who brought single atoms into focus

The European Patent Office (EPO) announces that Austrian experimental physicist and entrepreneur Maximilian Haider has been nominated for the European Inventor Award 2019 as one of three finalists in the category "Lifetime achievement" for his pioneering technique to improve the resolution of electr more
Monitoring the lifecycle of tiny catalyst nanoparticles

Since they are so tiny, it is difficult to investigate single nanoparticles. However, this is exactly what researchers are aiming for in order to tailor their properties. A novel approach: particle at the stick. Nanoparticles can be used in many ways as catalysts. To be able to tailor them in such a more
New molecular blueprint advances our understanding of photosynthesis

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have used one of the most advanced microscopes in the world to reveal the structure of a large protein complex crucial to photosynthesis, the process by which plants convert sunlight into cellular energy. more

Size and element specific determination of Ag nanoparticles in consumer spray products using asymmetric flow field flow fractionation (AF4) coupled to ICPMS

The use of nanoparticles in consumer products shows a tremendous increase over the past years. A study of the Woodrow Wilson International Centre for Scholars reported that between 2005 and today the number of products based on nanoparticles increase more

“Tubular J-Aggregates of a New Thiacarbocyanine Cy5 Dye for the Far-red Spectral Region – A Spectroscopic and Cryo-Transmission Electron Microscopy Study”

The aggregation behavior of a phenol-substituted thiacarbocyanine Cy5 dye (5-chloro-2-[5-[5-chloro-3-(4-sulfobutyl)-3H-benzothiazol-2-ylidene]-3-phenyl-penta-1,3-dienyl]-3-(4-sulfo¬butyl)-benzothiazol-3-ium hydroxide, inner salt, triethylammonium salt) in aqueous solution is investigated using stead more
In situ atomic-scale observation of inhomogeneous oxide reduction

We report in situ atomic-scale transmission electron microscopy observations of the surface dynamics during Cu2O reduction. We show inhomogeneous oxide reduction caused by the preferential adsorption of hydrogen at step edges that induces oxygen loss and destabilizes Cu atoms within the step edge, t more
Silver nanoparticle embedded copper oxide as an efficient core–shell for the catalytic reduction of 4-nitrophenol and antibacterial activity improvement

A facile and eco-friendly method was developed to prepare a microporous CuO@Ag0 core–shell with high catalytic and antibacterial activities. Scanning and transmission electron microscopy revealed a preponderance of nearly spherical 50 nm particles with slight structure compaction. Comparison of the more
