Course: Nanomaterials 1

Department/Abbreviation: KEF/NM1

Year: 2021

Guarantee: 'doc. RNDr. Karolína Šišková, Ph.D.'

Annotation: The aim of this course is an introduction to basic aspects of nanomaterials, namely their syntheses and properties. Gained knowledge can be further exploited in Bc, Diploma and PhD theses dealing with particular nanomaterials.

Course review:
1. nanoclusters and nanoparticles - Feynman`s vision; bulk and interface; gradients near surfaces; surface science, particle size, biomimetics, colloids 2. geometric structure, magic numbers, and coordination numbers of nanoclusters 3. electronic structure: discrete vs. band structure; the effects of dimensionality and symmetry in quantum structures; quantum dots; the nonmetal-to-metal transition; work function, ionisation potential and electron affinity, electronic structure of metal and semiconductor nanoclusters/nanoparticles 4. thermodynamics for finite size systems: limitations of macroscopic thermodynamics, the basics of capillarity, the lotus effect, classical nucleation theory, shape control of nanocrystals, principles of self-assembly 5. phase transitions and dynamics of clusters; 2D systems and their phase transitions 6. colloids; mechanisms of nanoclusters and nanoparticles formation; stability of nanoparticle systems; basic principles, interparticle forces; nanoparticle stability and their destruction 7. syntheses of nanomaterials - types, more about (i) laser ablation and (ii) bottom-up approach + their mechanisms
