Post-doctoral position at Comenius University in Bratislava, Slovakia

Annotation:

Laser-induced breakdown spectroscopy (LIBS) is a powerful analytical technique that can be used to detect and characterize materials. LIBS utilises a highly energetic laser pulse focused onto the surface of a solid, liquid, gas, or cloud of aerosolized particles to create a micro-plasma on the sample surface. This analytical technique offers many compelling advantages compared to other elemental analysis techniques such as flexibility, compactability, minimal sample preparation and in situ applications. However, LIBS suffers several drawbacks e.g., matrix effect, self-absorption and self-reversal effect which affect the detection limit of the methodology. To enhance quantification and the detection limit of LIBS, a combination of techniques is used such as LIBS assisted by, laser-induced fluorescence (LIF), Raman scattering, laser ablation molecular isotopic spectrometry (LAMIS). The main activities of the group are experimental investigations on laser spectroscopy for both qualitative and quantitative analysis. Particularly, single and double pulse laser-induced breakdown spectroscopy, fast and ultrafast lasers (ns, ps, ft), fiber laser or OPO, plasma re-excitation (R-LIBS, RE-LIBS, LIBS-LIF), molecular spectroscopy (LAMIS, CRM) and combinations of the techniques related to the above fields. Experimental activities are supported by chemometric methods and computer simulations.

Objectives

To study the fuel retention in fusion samples using Laser-induced breakdown spectroscopy (LIBS). To develop the various combination of spectroscopic techniques with LIBS. To study the enhancement in limit of detection low-Z elements using VUV- LIBS and LIBS assisted by resonance excitation viz. R-LIBS, LIBS-LIF. To design new experiments and carry out independent research to study the quantification of elements in geological samples and fusion relevant materials. Liquid analysis is performed in our group using surface assisted LIBS, development of an experimental setup for bulk liquid analysis is also in planned agendas.
