During the past decade, polymer nanocomposites have emerged as a novel and rapidly developing class of materials attracted considerable investment in research development worldwide. However, there is currently lack information available literature on nano ultrafine particle emission rates from these materials. In this paper, influence nanoclay mechanical drilling PA6 composites, terms dust generation, has been reported. With help real‐time characterization, submicrometer‐sized particles...
Structural characterization of a series novel bio-polyamides based on renewable raw materials—PA 4.10, PA 6.10, 10.10, and 10.12—was performed by Fourier transform infrared spectroscopy (FTIR) wide-angle X-ray diffraction (WAXD). Infrared spectra the WAXD patterns indicate coexistence different crystalline forms, α- γ-triclinic β-pseudohexagonal. Thermal properties in glass transition (T g) melting region were then investigated using temperature-modulated DSC (TOPEM® DSC). The point m) was...
The surface modification of cellulose nanocrystals (CNC) is a key intermediate step in the development new functionalities and tailoring nanomaterial properties for specific applications. In area polymeric nanocomposites, apart from good interfacial adhesion, high thermal stability vitally required stable processing improvement material properties. this respect, heterogeneous esterification CNC with succinic anhydride was investigated work order to obtain optimised influence reaction...
The wider use of renewable feedstock in structural applications, where high mechanical performance is required, can be achieved by the application recently developed engineering biopolymers and their further modification micro- nanoparticles. In this review, we present current state art biopolyamide materials for functional applications. overview includes all stages manufacturing—from synthesis building blocks, through polymers its physical modification, with special emphasis on properties...
We compared the antithrombotic effects in vivo of 2 chemically different carbon monoxide-releasing molecules (CORM-A1 and CORM-3) on arterial venous thrombus formation hemostatic parameters such as platelet activation, coagulation, fibrinolysis. The hypotensive response to CORMs their whole blood gas analysis cell count were also examined.CORM-A1 (10-30 µmol/kg, i.v.), a dose-dependent fashion, significantly decreased weight electrically induced rats, whereas CORM-3 inhibited thrombosis only...
In this work FTIR studies on blood plasma in the rat models of hypertension are reported.
Coffee may exert a preventive effect on arterial thrombosis. Trigonelline is one of the most abundant compounds in coffee that undergoes pyrolysis upon roasting beans. The aim present study was to identify pyridinium formed trigonelline and investigate three them, i.e., 1-methylpyridine 1,3- 1,4-dimethylpyridine, experimentally induced thrombosis rats. 1,4-dimethylpyridine but not inhibited thrombus formation. 1,3-Dimethylpyridine platelet aggregation reduced fibrin formation platelet-rich...
Introduction: ACE2 alternatively converts angiotensin (Ang) II into Ang-(1–7) and Ang I Ang-(1–9). There is little information in the literature with respect to Ang-(1–9) properties. A number of studies show a link between peptides renin-angiotensin system thrombosis. Materials methods: We have investigated influence on stasis-induced venous thrombosis rat. The contribution coagulation fibrinolytic systems, receptor type 1 (AT ) MAS mode action was also determined. Results: enhanced...
Introduction. Cervical cancer in Poland has a higher incidence and mortality rates, lower 5-year survival rates compared to Western Europe. The Polish government initiated screening vaccination programs improve outcomes. This study reviews cervical epidemiology assesses adherence preventative measures. Additionally, we tried assess the potential for improving epidemiological situation future. Material methods. Data were collected from National Cancer Registry Health Fund. We performed desk...
During the past decade, polymer nanocomposites have emerged as a novel and rapidly developing class of materials attracted considerable investment in research development worldwide. However, there is currently lack information available literature on emission rates particles from these material. In this study, real-time characterization size distribution number concentration sub-micrometer-sized (5.6-512 nm) emitted polyamide 6 during mechanical drilling was made. For first time, four...
Novel bio-polyamides obtained from renewable resources, e.g. PA4.10, are considered nowadays as promising ‘green’ engineering materials consisting of building blocks derived castor oil. In this work the composites heterogeneously acetylated microfibrillated cellulose (MFC) and biopolyamide 4.10 have been prepared by melt blending. Thermoplastic processing PA4.10/MFC was possible in a narrow temperature window due to significant improvement thermal stability MFC compared raw MFC. The increase...
ABSTRACT A top‐down approach is applied for the production of polyurethane (PU)–polyhedral oligomeric silsesquioxane (POSS) nanocomposites, namely melt blending. As opposed to typical chemical incorporation during synthesis, a POSS moiety with two hydroxyl groups blended into commercial thermoplastic mass fraction up 2 wt %. disperses in matrix submicrometer‐sized crystals, as well length scale few tens nanometers, bulk. Phase separation produced composites was studied by both standard...
