Effect of thermal annealing on a bilayer polyvinyl alcohol/polyacrylic acid electrospun hydrogel nanofibres loaded with doxorubicin and clarithromycin for a synergism effect against osteosarcoma cells
(Elsevier, 2021-08-02)
Polyvinyl alcohol/polyacrylic acid (PVA/PAA) bilayer hydrogel nanofibres were successfully fabricated by
electrospinning and physically crosslinked via heat treatment. The effects of the thermal annealing
process on the ...
Ti-25Nb-25Ta alloy treated by plasma electrolytic oxidation in phosphoric acid for implant applications
(Rede Latino-Americana de Materiais, 2021)
Among titanium alloys with non-toxic elements, the Ti-25Nb-25Ta alloy has good elastic behavior for applications in osseous implants, biocompatibility, and excellent corrosion resistance. The present study aimed to
better ...
Scratch-resistant and well-adhered nanotube arrays produced via anodizing process on β-titanium alloy
(Elsevier, 2021-03)
Well-adhered nanotube arrays were produced through the anodizing technique on a Ti-25Nb-25Ta alloy and tribo-mechanically evaluated by nanoindentation and nanoscratch tests. Disregarding substrate effects, the hardness of ...
Development of electrospun PVA nanofibers via freeze-thawing method
