  - Rok 2023

  Positioning, Navigation, and Timing (PNT) information play a vital role in everyday life of common persons. People greatly rely on Global Navigation Satellite System (GNSS)-enabled applications for navigation to reach their desired destination. However, GNSS navigation performance is highly degraded in urban environments due to the high probability of signal interruption, multipath (MP), and/or non-line-of-sight (NLOS) signal...

  The paper discusses the relationship between rheology and morphology of immiscible polypropylene (matrix))/polycarbonate (dispersed phase) blends compatibilized with novel polypropylene-polycaprolactone block and graft copolymers. Transmission electron microscopy (TEM) experiments revealed uniform droplet morphologies and a reduction of the average size of the dispersed phase upon addition of the compatibilizer. The results suggested...

  - Engineering of Biomaterials / Inżynieria Biomateriałów - Rok 2023

  The objective of this article is to present materials and technology for the manufacture of vascular stents with appropriate design requirements. The use of the right material is very important in implantology. A biomaterial introduced into the circulatory system must be biocompatible and hemocompatible. At the same time, it should not initiate toxic, mutagenic, or immunological reactions. Currently, 316L stainless steel (316L...

  - seria: Additive manufacturing technology of electroactive three-dimensional structures from diamond reinforced polylactide composites

  This dataset contains broadband dielectric spectroscopy studies of commercially available ProtoPasta 3D printable filament, composed of poly-lactic acid (PLA) and conductive carbon black (CB) filler. The aim of the study is to observe structural differences and applied properties changes under multiple reprocessing of the composite material at different...
