This year during Science Festival we had a pleasure to invite to our laboratory extremely large group of students from various primary schools and gymnasiums from Warsaw and surrounding area. Around 80 students with they teacher attended to lectures and laboratory tours. This year four topics have been presented: Small is beautiful - the thing about polymercrystal, The invisible world – t o see by scanning electron microscope’s eye, Regeneration of the knee using 3D polymer structures and How much heat it is needed to melt chocolate?. 

Prof. Paweł Sajkiewicz carefully explained ,,young scientists'' what is the difference between crystal and amorphous materials and what properties are related with polymer structure. Moreover, students could observecrystal structures of polymers by themself. Judyta Dulnik presented possibilities which gives us scanning electron microscope. For this purpose, our team prepared for them various biological preparations and some nanofibres produced in our laboratory. Finally, Dr Dorota Kołbuk and Dr Tomasz Kowalczyk presented electrospinning process and explained potential application of fibers mat. The electrospinning process has been show from solution preparation to fiber formation. How much heat it is needed to melt chocolate? leacture and laboratory show has focused great interest as well. This leacture has been prepared by prof. Paweł Sajkiewicz, Dr Arkadiusz Gradys and Olga Urbanek. On this leacture students try to answer various important questions eg.: what influace on melting temperature of materials? what exactly is melted in chocolate? does all chocolates melt in the same temperature? how we can measure ammount of heat need to melt chocolate?

 

We are very happy that we could meet soo many great young people! We hope meet you next years!
