  • Electron Microscopy Sample Preparation: “The Future is Cold, Dynamic and Hybrid”

    In 2014, the renowned Electron Microscopy for Materials Science (EMAT) research lab at the University Antwerp, Belgium, and Leica Microsystems started a fruitful collaboration to establish a Leica Reference Site in Antwerp. This site, officially opened in July 2014, is dedicated to specimen preparation for electron microscopy in materials science with a special focus on ion beam milling and recently also on carbon coating. In this interview Prof Gustaf van Tendeloo, Director of EMAT, and Frédéric Leroux, TEM specimen preparation specialist, talk about research topics at EMAT, how the Leica reference site has evolved, and future trends for EM sample preparation.

  • Multilayered Polyelectrolyte Microcapsules: Interaction with the Enzyme Cytochrome C Oxidase

    Cell-sized polyelectrolyte capsules functionalized with a redox-driven proton pump protein were assembled for the first time. The interaction of polyelectrolyte microcapsules, fabricated by electrostatic layer-by-layer assembly, with cytochrome c oxidase molecules was investigated. We found that the cytochrome c oxidase retained its functionality, that the functionalized microcapsules interacting with cytochrome c oxidase were permeable and that the permeability characteristics of the microcapsule shell depend on the shell components.

  • Exclusive Aesthetics of Nature

    Gemstones have fascinated people for thousands of years. Rulers and kings used to demonstrate their power and wealth with jewel-studded insignia. Although fine jewellery is still a status symbol of the rich, we now tend to treasure these wonders of nature more for our own pleasure in beauty and harmony.
