International Conference on Laser Ablation (COLA) 2017

The National Technical University of Athens (NTUA) will be attending COLA 2017, which will be taking place in Marseille, France between the 3rd to the 8th September 2017. The conference brings together scientists from around the world to discuss the latest scientific and technological advances related to new fundamental and applied aspects of laser ablation.


Laser ablation relies on a wide range of physical and chemical mechanisms taking place at different temporal and spatial scales, starting from attosecond and atomic size. Scientific community investigates this field for thirty years and numerous questions are still open. Moreover, new exciting challenges continuously appear with the fast technological advances of the laser sources and the characterization techniques. Laser ablation is also the starting point of a large amount of industrial processes in many application fields like manufacturing, microelectronics, automotive, diagnostics, medical and others. 


NTUA will present a poster on the early results within the HiperLAM Project on 'Laser Induced Forward Transfer of Metallic inks: printing and jetting studies'. The poster will 'illustrate and provide a detailed discussion of the dynamic behavior of silver and copper nanoparticle inks during laser driven drop ejection to understand the jetting evolution of the Nano Particle inks in order to predict the uniform and reproducible formation of electrode patterns on flexible substrates. In addition, a combination of modelling and imaging experiments allows to gain further insight into the ejection dynamics of the LIFT process' (Makryianni et al., 2017).


Furthermore, a set of experimentally-driven simulations based on the Volume-Of-Fluid (VOF) method is employed, taking into consideration material properties (i.e viscosity, surface tension) of the silver NP inks. This study provided further insight into the jetting behavior and deposition process, and allowed to determine the optimum printing operation window. Finally, a correlation between modelling and experimental results is carried out, showing that they are in good agreement.
