Molecular simulations of interactions among CdS nanoparticles and montmorillonite
Pšenička, Milan ; Pospíšil, Miroslav (advisor) ; Malý, Marek (referee)
This thesis investigate the structure of cadmium sulfide (CdS) nanoparticles and its stabilization by a surfactant - cetyltrimethylamonnium cation CTA+ and further describe interactions among stabilized CdS nanoparticles and the surface of the layered clay mineral - montmorillonite with using the molecular simulation methods. Initial models of the CdS nanoparticles were build for both crystal structures (Greenockit (G) and Hawleyit (H)). The preferred orientations of the molecules of CTA+ for both crystal types of CdS nanoparticles were found with respect to minimum energy. Prefered orientation is monolayer for Greenockite and bilayer for Hawleyite. Models with the preferred orientation of the molecules of CTA+ were placed on the surface of montmorillonite and after optimization, adsorption energy of CdS nanoparticles with its envelope and montmorillonite surface was calculated. All results and used procedures were compiled in the form of practice for the subject Computational experiments in the theory of molecules I - NBCM100 taught at MFF UK in Prague.

Název práce: Z historie spinu Autor: Milan Pšenička Katedra: Katedra chemické fyziky a optiky Vedoucí bakalářské práce: RNDr. Vojtěch Kapsa, CSc., Katedra chemické fyziky a optiky Abstrakt: Tento text by měl sloužit jako doplňkový materiál při výuce spinu a fyziky 20.století. Zábývá se historickým pozadím zavedení spinu a dvěma experi- menty, které přímo vedli k potvrzení jeho existence a to pokusem Einsteinovým - de Haasovým a pokusem Sternovým - Gerlachovým. Rozbor těchto experimen- tů je proveden na základě původních článků a historický kontext je čerpán z přehledových publikací o historii fyziky. Klíčová slova: spin, Sternův - Gerlachův pokus, Einsteinův - de Haasův pokus Title: Episodes from History of Spin Author: Milan Pšenička Department: Department of Chemical Physics and Optics Supervisor: RNDr. Vojtěch Kapsa, CSc., Department of Chemical Physics and Optics Abstract: This thesis can be used as a supplementary material for teaching the 20th century physics and the history of spin. It deals with the historical bac- kground of discovery of spin and two experiments that confirmed directly its existence, namely the Einstein - de Haas and Stern - Gerlach experiments. Dis- cussion of these experiments is based on the original articles and the historical context is drawn from the publications on the...
