Al 2 O 3 , MgO, two glass powders with different SiO 2 contents, and natural zeolite powder were selected as fillers. The fillers individually were added to the polymer matrix in proportions of 50 and 70% by weight. A hybrid filler-containing composite was created by mixing PA6/70 wt% MgO and PA6/80 wt% zeolite. The results show that the thermal conductive enhancement factor is highest for PA6/70 wt% Al 2 O 3 (145%) and PA6/hybrid fillers 75 wt% (92%). The Lewis-Nielsen and Reciprocity models agreed with the measured data with less than 26% deviation, except for the MgO-loaded composites. In the case of a hybrid composite, the additive model proves to be a good approximation. The abrasive effect of the different fillers was characterised by the volume loss of the steel pin using the pin-on-disc method. A new parameter is developed that considers the thermal conductivity enhancing effect of the fillers and their abrasive effect. In addition to ceramic fillers, aluminium-hydro-silicate, e.g. natural zeolite, and their mixtures offer new opportunities for the development of thermally conductive composites, as they are more economical to use in manufacturing processes.}, year = {2023}, eissn = {2045-2322}, orcid-numbers = {Czél, György/0000-0003-3807-3988; Czél, Györgyné/0000-0001-6372-2850} } @{MTMT:33198453, title = {Égésgátolt homlokzatszigetelő panel}, url = {https://m2.mtmt.hu/api/publication/33198453}, author = {Velősy, András and Dr.Józsa, Zsuzsanna and Czél, György}, unique-id = {33198453}, year = {2022}, orcid-numbers = {Czél, György/0000-0003-3807-3988} } @{MTMT:32556742, title = {Külső zárású polimer szelep}, url = {https://m2.mtmt.hu/api/publication/32556742}, author = {Czél, György and Almási, Péter}, unique-id = {32556742}, year = {2022}, orcid-numbers = {Czél, György/0000-0003-3807-3988} } @article{MTMT:32213917, title = {Amorphous alloys and differential scanning calorimetry (DSC)}, url = {https://m2.mtmt.hu/api/publication/32213917}, author = {Czél, Györgyné and Kissné Svéda, Mária and Sycheva, Anna and Kristály, Ferenc and Zámborszky, Ferenc and Koziel, Tomasz and Bala, Piotr and Czél, György and Kaptay, György}, doi = {10.1007/s10973-021-11054-0}, journal-iso = {J THERM ANAL CALORIM}, journal = {JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY}, volume = {147}, unique-id = {32213917}, issn = {1388-6150}, abstract = {A remarkable number of scientific papers are available in the literature about the bulk amorphous alloys and metallic glasses. Today, DSC is an essential tool for amorphous alloys research and development, and of course for quality assurance. In many cases, users seek to examine the determination of only one or two properties, although much more information can be obtained from the measurements. The research involved structural relaxation, Curie temperature, glass temperature, crystallization, phase separation, nanocrystalline volume fraction, melting point and liquidus temperature determination subjects and kinetics of microstructural transformations induced by thermal treatment. We collected and present the information that can be obtained with this technique and draws the reader’s attention to some potential problems related to data interpretation.}, year = {2022}, eissn = {1572-8943}, pages = {7141-7157}, orcid-numbers = {Czél, Györgyné/0000-0001-6372-2850; Kissné Svéda, Mária/0000-0003-0655-1711; Kristály, Ferenc/0000-0002-0075-5994; Czél, György/0000-0003-3807-3988; Kaptay, György/0000-0003-4419-142X} } @article{MTMT:32092389, title = {Antimicrobial effect of silver nanoparticles plated natural zeolite in polyurethane foam}, url = {https://m2.mtmt.hu/api/publication/32092389}, author = {Czél, György and Vanyorek, László and Sycheva, Anna and Kerekes, F. and Dorogházi, Emma and Czél, Györgyné}, doi = {10.3144/expresspolymlett.2021.68}, journal-iso = {EXPRESS POLYM LETT}, journal = {EXPRESS POLYMER LETTERS}, volume = {15}, unique-id = {32092389}, issn = {1788-618X}, year = {2021}, eissn = {1788-618X}, pages = {853-864}, orcid-numbers = {Czél, György/0000-0003-3807-3988; Czél, Györgyné/0000-0001-6372-2850} } @{MTMT:31148114, title = {Élénkített hatású antibakteriális poliuretánhab és eljárás annak előállítására}, url = {https://m2.mtmt.hu/api/publication/31148114}, author = {Czél, György and Vanyorek, László and Dorogházi, Emma}, unique-id = {31148114}, year = {2019}, orcid-numbers = {Czél, György/0000-0003-3807-3988} } @CONFERENCE{MTMT:31148058, title = {Antimicrobial effect of Ag+ and Cu2+ inon exchanged zeolite nanoparticles in polyurethane foam.
