*Navedena porazdelitev ur velja, če je vpisanih vsaj 15 študentov. Drugače se obseg izvedbe kontaktnih ur sorazmerno zmanjša in prenese v samostojno delo. / This distribution of hours is valid if at least 15 students are enrolled. Otherwise the contact hours are linearly reduced and transfered to individual work.

Vsebina:
Content (Syllabus outline):

Morfološke in kristalografske lastnosti organskih in anorganskih nanodelcev: vlaken, iglic, kroglastih nanodelcev, ki so vsaj v eni smeri manjši od 100 nm. Metode za zbiranje in sortiranje nanodelcev po velikosti in masi v tekočih in plinastih medijih (večstopenjski impaktorji, elektrostatična klasifikacija).

Specifične fizikalne in kemijske lastnosti nizkodimenzionalnih sistemov: samourejanje, aglomeriranje, rekonstrukcije, relaksacije, fazni prehodi, kvantni efekti. Sinteza ekvivalentnih nanodelcev v laboratorijskih pogojih v zadostnih količinah za uporabo makroskopskih karakterizacijskih metod. Detekcija kemijske aktivnosti pri zmanjševanju dimenzij nanodelcev z ozirom na biokompatibilnost oz. toksičnost.

Metode za karakterizacijo nanomaterialov: visokoločljivostna presevna elektronska mikroskopija, vrstična elektronska mikroskopija, vrstična tunelska mikroskopija in spektroskopija, mikroskopija na atomsko silo, spektroskopija elektronskih izgub energije. Pregled osnovnih metod za kontrolo namenske proizvodnje oz. nenamenske emisije nanodelcev v delovno in splošno okolje.

Obravnavani primeri bodo prilagojeni ciljem in vsebini raziskovalnega projekta podiplomca.

Morphological and crystallographic properties of organic and inorganic nanoparts: fibres, needles, spherical nanoparts which are smaller than 100 nm at least in one direction. Methods of collecting and sorting of nanoparts by size and mass in crystal and gaseous media (multistage impactors, electrostatic classification).

Specific physical and chemical properties of low-dimensional systems. Self-arrangement, agglomeration, reconstructions, relaxations, phase transfers, quantum effects. Synthesis of equivalent nanoparticles in laboratory conditions in adequate quantities for use of macroscopic characterization methods. Detection of chemical activity in reducing dimensions of nanoparticles regarding biocompatibility and/or toxicity.

Methods of characterization of nanomaterials: high-resolution transmission electronic microscopy, scanning electronic microscopy, scanning tunnel microscopy and spectroscopy, atomic force microscopy, spectroscopy of electronic energy losses. Overview of the basic methods for monitoring of intentional generation or accidental emission of nanoparticles into the occupational and general environment.

The cases under consideration will be adapted to the objectives and content of the postgraduate student's research project.
