Selected chapters from nanomaterials

This course is part of the programme:
Materials (Third Level)

Objectives and competences

Students get to know the meaning of the “nano” in correlation to materials – they understand the meaning of their size in comparison to bulk materials, atoms and molecules. They learn about specific phsyco-chemical properties of nanomaterials and related applications. They understand, for which applications nanomaterials are superior to their bulk counterparts.

They learn basic physical techniques and chemical synthesis methods for the preparation of nanomaterials, and basic procedures for surface functionalization and coating of nanomaterials. They learn basics of colloidal chemistry in correlation to interparticle interactions. This knowledge is further upgraded with the knowledge on the assembly of nanoparticles into complex materials. They are intrduced to exmaples of such materials.

They get an insight into characterization methods for nanomaterials, toghether with the problematics related to their small size. They learn to properly select and combine different analyticial methods for comprhensive charcaterization of nanomaterials.

They are acquainted with safety issues of handling with nanomaterials, specifically with nanoparticles, and their potential toxicity.

Prof. Dr. Darja Lisjak (h index = 18) is senior scientific associate at Jožef Stefan Institute, at Department for Materials Synthesis. Her research focus is synthesis and characterization of materials (nanomaterials, hybrid materials, films), assembly of nanoparticles into functional materials, surface and colloidal chemistry.

She received B.Sc. in chemistry in 1993 from Faculty of Chemistry and Chemical Technology of University of Ljubljana. She accomplished her doctoral studies as young researcher at Jožef Stefan Institute and graduated in 1999 from Materials Science at Faculty of Chemistry and Chemical Technology of University of Ljubljana. During this time, 1997/98, she was a visiting associated at University of Pennsylvania. Since then she was employed at Jožef Stefan Institute and during the period of 2010–2013 also as a senior scientific associate at Centre of Excellence COBIK. She was a visiting senior researcher at University of Trieste in 2015. She was involved in several EU projects and projects with Slovenian companies as a coordinator or principal investigator. She and her co-worker, dr. Alenka Mertelj, received Zois recognition for the discovery of ferromagnetic liquid-crystal suspensions.

She is involved at Jožef Stefan International Postgraduate School since 2006 and she was promoted to Associated Professor in 2016. Currently she is a leader of the course Nanoparticles, colloidal and surface chemistry. She has been mentoring several PhD students and two BSc students.
