Grazing-incidence Small-angle X-ray Scattering Technique for Probing Nanostructures and Processes at Nanoscale
The paper presents the grazing-incidence small-angle X-ray scattering technique and its application to the studies of self-assembly and re-assembly effects of colloidal nanoparticles. Two basic cases are exemplified - solvent evaporation driven self-assembly and self-assembly driven by barrier movement in the Langmuir-Blodgett trough. Studies of the nanoparticle re-assembly effects due to the surfactant removal
complete the overview. These examples document strength of GISAXS for an in situ tracking of processes at nanoscale. The results have direct implications for tailored preparation of the self -assembled nanoparticle templates for sensing, plasmonics and other applications

Nitric Dioxide and Acetone Sensors Based on Iron Oxide Nanoparticles
The Fe2O3 and CoFe2O4 nanoparticle-based Langmuir–Blodgett films for sensing of nitric dioxide(NO2) and acetone vapours have been explored. Both the sensitivity of the chemiresistors anddynamic properties, such as the response/recovery time, have been probed in dependence of thenumber of nanoparticle monolayers and working temperatures. The response of 23 at the NO2concentration of 1 ppm, i.e., approaching the canine detection limit, has been monitored implyingthe appropriateness for the detection of nitrate-based explosives
