Student's Thesis

Dissertation

Graphene Synthesis by Carbon Nanotubes Exfoliation

Experimental work will focuse on carbon nanotubes exfoliation by oxidation or  alkaline metals intercalation. Carbon nanotubes and synthesised graphene ribbons will be characterized by Raman spectroscopy, FTIR, STM, AFM and other advanced methods.

2D Nanomaterials Synthesis -  „bottom-up“ Processes

2D inorganic materials based on MoS2 and similar substances show quite unique properties.  Materials will be synthesised from various  precursors under hydrothermal conditions. Process optimalization leads to preparation of materials with desired structure and number of layers. Characterization will be done by advanced analytical techiques like AFM, Raman spectroscopy and photoluminescence measurements.

Master Thesis

Synthesis and Electrocatalytic Properties of Layerd Carbides

This work will be focused on develepment of layerd carbides (so called MEX) synthesis and optimalization of its chemical exfoliation methods.  Student will study potential of exfoliated carbides use in electrocatalysis. Materials will be characterised by XPS, AFM, Raman spectroscopy and SEM/TEM.

Bachelor Thesis

Gas Detectors Based on Layerd Chalcogenides

Experimental work will be focused on synthesis and following exfoliation of 5th and 6th group dichalcogenides. Student will study their use in gas detection by impedance spectroscopy. Materials and sensoric structures will be characterised by  SEM, AFM, XPS and Raman spectroscopy.
