Vortragseinladung Prof. Marek Koutny und Dr. Petr Stloukal am 25. März 2015

Lecture at 10 a.m.: Biodegradable polymers in real conditions

The biodegradability of polymers and polymeric materials depends strongly on conditions to which they are exposed. Consequently the actual biodegradability could be a complex interrelation between several biotic and abiotic factors. Even materials in the seemingly homogenous group of polyesters like PCL, PBAT, PBS, PLA probably differ in their mechanism of the biodegradation. PLA and PBAT are both biodegraded almost exclusively under composting conditions but in the case PBAT this is probably caused with the requirement for specific enzymes produced by a group of thermophilic bacteria, PLA simply requires higher temperature because the abiotic hydrolysis of ester bonds, with its strongly temperature dependent kinetics, representing a necessary firsts step in the decomposition mechanism. Polymer biodegradation in real polymeric formulation could also be influenced by other components present in the given blends.

Lecture at 10.45 a.m.: The influence of a hydrolysis-inhibiting additive on the degradation and biodegradation of PLA and its nanocomposites



Dr. Petr Stloukal 
Tomas Bata University Zlin


PLA based materials can suffer from relative susceptibility of PLA towards hydrolysis. This could especially complicate thermoplastic processing of the materials because higher temperatures significantly increase the rate of hydrolytic reactions. Commercially available carbodiimide-based additive intended to stabilize PLA based materials against hydrolytic degradation were incorporated into a series of PLA and nanofiller containing PLA films.  The influence of the additive on the subsequent degradability of the materials was studied under the conditions of melt processing, biodegradation in compost and abiotic hydrolysis. Identical films without the additive were used as reference materials. Adding an anti-hydrolysis agent significantly retarded the decomposition of PLA in all the degradation processes tested. Both biodegradation and the abiotic hydrolysis of the PLA-based materials investigated were substantially retarded. This effect was much less pronounced in a material with organically modified montmorillonite.

Vortragseinladung Prof. Ewa Wäckelgard am 3. Februar 2015


Ewa Wäckelgard has PhD degree in Physics (1987) with specialization in materials physics. She is professor in solid state physics at Uppsala University from 2004 and also from 2007 in energy technology at Dalarna University. Her research interest is in materials optics with focus on coatings for solar absorbers for photo-thermal conversion. She has also research activities in energy systems studies and is programme director in a graduate school.



Development of solar absorbing surfaces - a review



Harvesting solar energy as heat is actively made in solar collectors with its main component, the solar absorber, with photo-thermal conversion. Absorbers can be designed in different ways but have in common the property to absorb most of the incoming solar radiation with lowest possible heat losses to the surrounding and to be chemically durable at high temperatures, to moisture and atmospheric pollutants.

The vast part of solar collectors are used for space heating and domestic hot water which means rather low temperatures, 50 to 100 °C in operation. It is also used in solar applications at higher temperatures, 300 to 500 °C (or even higher) for industrial pr0cesses and electricity generation.

The main focus in this presentation is to review the development in solar absorber development from the earlier processes of chemical and electrochemical conversion to physical and chemical vapour deposition, and later on sol gel and chemical solutions for dipping or spraying coatings.

Vortragseinladung Guido Panzarasa, M.Sc. am 2. Dezember 2014


Guido Panzarasa, M.Sc., Department of Science and Technological Innovation, University of Eastern Piedmont "Amedeo Avogadro", Alessandria (Italy)

Guido Panzarasa was born in 1988. He obtained a B.Sc. in Materials Science in 2010  and a M.Sc. in Chemical Sciences in 2012 from the University of Eastern Piedmont "Amedeo Avogadro", Alessandira (Italy) working on the synthesis and characterization of core-shell silica nanoparticles for plasmonic and photonic applications. He started his PhD in 2012 in the same Insitution under the supervision of Dr. Katia Sparnacci, focusing on the realization of patterned, functional polymer brushes by means of controlled radical polymerization.



Silicon Dioxide: a Playgrund for Nanotechnology and Surface Engineering


Since the seminal work of Stöber et al. [1] silica nanoparticles and functional siloxanes have become fundamental building blocks for the realization of complex structures on the nanoscale and for surface engineering by self-assembled monolayers (SAMs). Controlled synthesis of silica nanoparticles by sol-gel techniques, along with the major factors affecting diameter and monodispersity, the chemistries enabling introduction of functional groups and subsequent loading with pro-drugs, flourescent probes and noble metal nanoparticles for applications in drug delivery, photonics and plasmonics will be discussed thoroughly. The relevance of SAMs for smart coatings will be also highlighted by taking advantage of real case studies.

Vortragseinladung Dr. Anna Maria Coclite am 30.Oktober 2014


Dr. Anna Maria Coclite is Assistant Professor at Institute for Solid State Physics, TU Graz


Well-adhered, conformal, thin (<100 nm) coatings obtained by Chemical Vapor Deposition (CVD) augment the capabilities of traditional surface modification techniques for different technological applications. Functional polymeric materials can be applied to virtually any substrate (organic, inorganic, rigid, flexible, planar, three-dimensional, dense or porous) at room temperature by CVD methods, In CVS polymerization, the monomer(s) are delivered to the surface through the vapor phase and then undergo simultaneous polymerization and thin film formation. By eliminating the need to dissolve macromolecules, CVD enables insoluble polymers to be coated and prevents solvent damage to the substrate. CVD film growth proceeds from the substrate up, allowing for interfacial engineering, real-time monitoring, and thickness control. Initiated-CVD has shown successful results in terms of rationally designed micro- and nano-engineered materials to control molecular interactions at material surfaces.
