About: Polyakova Marina was born in Minsk, Buelorussia. After graduation from mechanical and technology faculty of Buelorussian politechnical institute in 1986 up to this date she has been working in Nosov Magnitogorsk state technical university at the mechanical and metallurgical department nowadays as assistant professor. Polyakova M. was awarded PhD in Metal Forming in 1998. In 2008 Polyakova Marina was awarded by the Commendation Diploma of Ministry of education and science of the Russian Federation. Since 2012 Polyakova M. is the Honorary Employer of high professional education of the Russian Federation.
Scientific activity of Polyakova M. is connected with quality control in metallurgical technological processes, qualimetry in hardware production and peculiarities of production quality formation in technologies of hardware manufacture. She is also interested in creating nanotechnologies based on combination different types of deformation. She has got two patents of the Russian Federation for an invention the continuous method of carbon wire deformation nanostructuring. Various hardware devices and tools already applied for steel wire production can be used to implement this method thus simplifying its introduction to the current industrial equipment.
Polyakova M. took part in many international conferences and last year she was the section chair at The Second International Conference on Pure and Applied Mathematics (St.Petersburg, 20-21 July). As a result of scientific work Polyakova M. wrote and published more than 75 papers among them papers published in referred journals. She is coauthor of three monographs about different aspects of downstream metal production.
Topic: “Preparing smart materials: shape-memory materials based on poly(urethanes) and thermo, photo and electroresponsive materials based on block copolymers and liquid crystals”
Abstract: In the last decade, the interest in stimulus responsive or ‘smart’ materials has increased enormously, owing to the possibility that their properties can be significantly changed in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH and electric or magnetic fields.
Shape-memory polymers represent a
subset of smart polymeric materials that have the
ability to be manipulated to retain or ‘fix’ a temporary
shape, and later recover to their ‘memorized’ original
(permanent) shape upon exposure to an external stimulus.
This functionality is useful for application in smart
fabrics, films for packaging, intelligent medical
devices, minimally invasive surgery, and many other
On the other hand, nanostructured thermosetting materials modified with block copolymers, which are able to form well-defined ordered nanostructures due to their self-assembly capability, have still been paid a great deal of attention. Besides, low molecular weight nematic liquid crystals (LC) show an orientational ordering that depends on an external field such as an electric field or temperature gradient which allows them to switch from the transparent to opaque state due to the birefringence feature of LC, when embedded in the polymer matrix. Thus, ternary electro-responsive thermosetting systems modified with block copolymer dispersed liquid crystals are receiving increased attention.
In this work, from one side, a new family of thermally activated shape-memory polymers based on segmented thermoplastic polyurethanes (STPUs), synthesized with different hard segment contents and polyols with different molecular weights, is prepared and characterized. On the other side, electro-responsive thermosetting systems modified with block copolymer-dispersed liquid crystals have been prepared and characterized. The competition between self-assembly of the block copolymer and the ability of the orientation of the LC microphase-separated domain when the electrical voltage is applied to the atomic force microscopy tip in the ternary system has been studied in terms of atomic force microscopy (AFM) and electrostatic force microscopy (EFM).
About: Galder Kortaberria was born in Donostia (Spain) in 1975. He studied Chemistry in the Basque Country University (EHU/UPV) from 1993 to 1998, with specialization in Polymer Chemistry. Then he started his PhD in the “Materials Engineering” program in the Polytechnic Engineering School of San Sebastian, under the supervision of Professor Iñaki Mondragon, about the monitoring of the cure process in epoxy matrices modified with thermoplastics or elastomers by simultaneous impedance and NIR spectroscopies. It was defended in 2004 with the qualification of Cum Laude. Then he obtained the permanent position in the same Polytechnic School as Associate Professor. As a senior member of GMT “Materials + Technologies” Group, his actual research is mainly devoted to the synthesis and characterization of copolymeric matrix-based nanocomposites with nanoparticles, nanotubes or other nanoentities. He has published more than 70 papers in high impact journals (with an h index of 19), has edited 2 complete books and published around 10 book chapters. He has directed 3 PhD thesis, and has presented more than 30 oral presentations in international conferences (3 of them as invited lecturer). He is nowadays reviewer in more than 20 journals. He has taken part in more than 50 projects funded by Spanish, Basque or European governments and companies, both as main or collaborator researcher.
