We are pleased to announce the third version of the NAMUS workshop from a collaboration between the MND axis at ISMO and the icnanotox group at JSU. The “Nano Manipulation of Atom & molecule using STM” workshop is devoted to specific lectures that will introduce basic STM techniques and DFT simulations methods. It will provide to graduated and PhD students general tools to understand and handle the first steps that may conduct them to prepare future experiments that combine scanning probe techniques and simulations using the density functional theory. Students may attend to 6 various lessons and 3 hands-on sessions with real DFT simulations and testing their skills on a small portable STM.
