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 ...
Yerba mate extract in microfibrillated cellulose and corn starch films as a potential wound healing bandage
(MDPI, 2020-11-27)
Microfibrillated cellulose films have been gathering considerable attention due to their high
mechanical properties and cheap cost. Additionally, it is possible to include compounds within the
fibrillated structure in ...
Evaluation of titanium nitride coatings in bandsaw blades for wood splitting by cold plasma
(Taylor & Francis, 2021-11-06)
Due to the advances in surface treatments, it is possible to obtain excellent cutting tools. However, the field for wood cutting tools still needs to be further investigated. In this work, titanium nitride was deposited ...
Effect of cullulose size-concentration on the structure of polyvinyl alcohol hydrogels.
(Elsevier, 2020-06-11)
Microfibrillated cellulose as a reinforcement agent has been investigated extensively due to their unique characteristics, which can reorder the structure of polymers and hydrogels leading to improved mechanical properties ...
Development, characterization and cell viability inhibition of PVA spheres loaded with Doxorubicin and 4′-Amino-1-Naphthyl-Chalcone (D14) for osteosarcoma
(MDPI, 2021-08-06)
Chalcones (1,3-diaryl-2-propen-1-ones) are naturally occurring polyphenols with known anticancer activity against a variety of tumor cell lines, including osteosarcoma (OS). In this paper, we present the preparation and ...
Bioactive composites fabricated by freezing-thawing method for bone regeneration applications.
(Wiley, 2016-04)
Hydrogels are widely used for controlled delivery of therapeutic agents. However, hydrogels lack bioactivity to encourage bone formation and mechanical integrity. Moreover, chemically crosslinked hydrogels exhibit cytotoxic ...
