Prof. Dr. László Zsidai - MATE Research
Overview
Dr. László Zsidai's main research areas revolve around Tribology, with a focus on examining the sliding and wear characteristics of polymer-metal dry friction systems through laboratory small-scale model testing. This includes exploring surface morphology, surface energy, and frictional heat. The goal is to identify optimal operating conditions in frictional applications for existing materials and emerging material developments.
Additionally, he is involved in Additive Technologies, investigating anisotropic material structures created via 3D printing. The research looks into the effects of printing orientation, infill, and layering, as well as exploring new material developments, such as composites.

Development of laboratory-scale high-speed rotary devices for microfibre formation for potential pharmaceutical and biomedical applications. The aim of the research is to investigate the production of polymeric microfibers and nanofibers by rotating centrifugal fiberization, which can be used in drug delivery and tissue engineering applications. The coordinated orientation of the fibers and, consequently, the improvement of the mechanical properties of the scaffold are essential in many pharmaceutical and biomedical applications where high tensile resilient materials are required. This study aimed to develop a high-speed rotary microfiber drawing device for the production of polyvinylpyrrolidone-based homopolymer and copolymer rotating braided fibers and to establish a relationship between the operating parameters of the devices and the morphology and microstructure of the manufactured fibers.
