Fabrication of nanostructures on graphene using AFM mechanical lithography and observation of their electronic response
 Belko, Peter ; Švarc, Vojtěch (referee) ; Bartošík, Miroslav (advisor)
Graphene is a suitable material for future sensors and biosensors due to its high sensitivity to the presence of adsorbents, low thermal noise, and biocompatibility. This work focuses on the lateral shaping of graphene on SiO2 using atomic force microscope-based mechanical lithography. The created barriers exhibit resistances on the order of hundreds of G and are applicable for nanosensor fabrication. Charge propagation is studied in this work through concurrent measurements of Kelvin probe force microscopy and macroscopic transport measurements at various humidities, corresponding to real conditions of atmospheric or solution-based sensors and biosensors.

The electrodiffusional theory for wall shear stress measurement by a two-strip probe: a journey to near-wall region hydrodynamics
 Harrandt, Václav
This contribution deals with a new theory describing mass transport in the vicinity of the measuring two-segment strip probe. Analytical formulas for the mass transfer coefficients of the front and the rear electrodes were derived. At the same time, the correctness of these formulas was confirmed by the numerical solution of the convectiondiffusion transport equation.
