11. Modelling of Catalytic Monolith Reactors for Exhaust Aftertreatment
Abstract : The incomplete combustion of liquid or gaseous fuels in the internal combustion engine inherently produces several toxic emissions that need to be removed. This is done through a series of catalytic converters, referred to as the exhaust aftertreatment system (EATS), each catalyst with its own purpose. READ MORE

12. Scanning electron microscopy (SEM) analysis of tribofilms enhanced by fullerene-like nanoparticles
Abstract : The beneficiary effects of WS2 inorganic fullerene-like nanoparticles in the lubrication industry were shown in recent years. The incorporation of the nanoparticles into lubricants (oils, greases) is however not straightforward. READ MORE

13. Scanning Tunnelling Microscopy Studies of Na Islands on Graphite, Impurity Interactions on Cu(111) and Low Temperature Structures of S/Cu(111)
Abstract : A scanning tunnelling microscope (STM) can reveal the atomic order of a surface as well as details of its electronic structure. In the present work STM, in combination with core and valence photo-electron spectroscopy and low energy electron diffraction (LEED) was applied to three different systems: (i) simple metal quantum wells in the form of Na films and islands on highly oriented pyrolytic graphite (HOPG), (ii) low temperature S/Cu(111) structures discovered in the course of this work and (iii) impurities on Cu(111).

15. Enamel of primary teeth - morphological and chemical aspects
Abstract : Enamel is one of the most important structures of the tooth, both from a functional and esthetic point of view. Primary enamel carries registered information regarding metabolic and physiological events that occurred during the period around birth and the first year of life. READ MORE
