An unusual science conference (not only) for young female scientists: April 29-30, 2018 Near the city of Goslar in the beautiful Harz mountains, an unusual science meeting is organised. The location is the Mönchehaus Museum (www.moenchehaus.de). I was attending this conference some years ago and I can really recommend it. The speakers are exclusively very renowned women in materials science, heading institutes at MIT, MPG or other prestigious research institutions. And multiple occasions are given to get into exchange with them. Discussions were open and vivid, and I guess many young women got motivated to strive for a scientific career. The organiser, Prof Katarina Al-Shamery, CarlRead More →

Nanoparticles are tiny, really tiny. Only a fraction of a micrometer or some nanometers in size. And only some thousands of molecules strong,  their properties can differ dramatically from those of their larger cousins. Titaniumdioxide, a whitish powder, can form such nanoparticles. In water, these nanoparticles can act as catalysts, when excited with light. and facilitate water splitting or water remediation. However, what happens exactly when TiO2 and water get into contact and which impact this is having on the electronic structure of TiO2 remained in the dark: it is very tricky to probe nanoparticle–water interface experimentally and to observe changes. Soft X-rays at BESSYRead More →

Last week 50 scientists from all over the world have gathered at BESSY II. Physicists or chemists, experimentalists or pure theoreticians. It was an interdisciplinary crowd, discussing openly and in an extraordinary friendly way about new and sometimes hypothetical processes in hybrid nanomaterials, how to model them and how to explore and characterizethem experimentally. Freigeist fellow Dr. Annika Bande has invited to this big workshop, sponsored by Volkswagen Foundation. Together with her young team, the theoretical chemist is modelling the dynamics of electrons in semiconductor materials , which upon miniaturization give rise to so called quantum dots. The result: Exchange and new ideas Her goalRead More →

For a long time, cybernetics was only seen in sci-fi (cyborgs like RoboCop and human enhancements like Inspector Gadget). A current limitation of electric prosthetics, is the human interface. Where the body rejects foreign objects. My project has been investigating a novel self-assembling material nanomaterial, acetylated β3-peptides. These have been demonstrated to assemble into fibers, and when coordinated to metals have been found to metallic like conductivity. As these mimic biological architecture, this material may be biocompatible, and as it forms 2D surface coverage, it’s possible to use it as to transport energy along molecular wires. β3-peptides represent an opportunity for the investigation of aRead More →
