    • Effect of cullulose size-concentration on the structure of polyvinyl alcohol hydrogels. 

      de Lima, Gabriel Goetten; Ferreira, Bruno; Matos, Mailson; Pereira, Bruno Leandro; Nugent, Michael J.D.; Hansel, Fabríco Augusto; Magalhães, Washington Luiz Esteves (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 ...

    • 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 

      Chee, Bor Shin; de Lima, Gabriel Goetten; de Lima, T.A.M.; Seba, Viviane; Lemarquis, C.; Pereira, Bruno Leandro; Bandeira, Marina; Cao, Zhi; Nugent, Michael J.D. (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 ...

    • Enhancement of mechanical properties and wettability of TiO2NT arrays formed in simulated body fluid‐based electrolyte. 

      Simon, Anna Paulla; Santos, Vidiany Aparecida Queiroz; Rodrigues, Andressa; Santos, Janaina Soares; Strixino, Francisco Trivinho; Pereira, Bruno Leandro; Lepienski, Carlos Mauricio; Sikora, Mariana de Souza (Wiley, 2019-09-13)
      Modified titanium nanotubes (TiO2NTs) coatings are grown in simulated body fluid (SBF) from Ticp and Ti6Al4V. The addition of 1% v/v of SBF to the electrolyte neither modifies film morphology nor the structural oxide ...

    • Oxide layer containing apatite formed on Ti-25Nb-25Ta alloy treated by two-step plasma electrolytic oxidation. 

      Pereira, Bruno Leandro; Beilner, Gregory; Lepienski, Carlos Mauricio; Szameitat, Erico Saito; Kuromoto, Neide Kazue; dos Santos, Leonardo Luis; Chee, Bor Shin; Alves Claro, Anna Paula Rosifini; Mazzaro, Irineu; Nugent, Michael J.D. (Elsevier, 2020-01-25)
      Hydroxyapatite (HA) is a bioactive calcium phosphate capable of enhancing the implant/bone connection improving osteoconductivity and osseointegration process. However, the HA presents mechanical properties limiting its ...

    • Scratch-resistant and well-adhered nanotube arrays produced via anodizing process on β-titanium alloy 

      Pereira, Bruno Leandro; Beilner, Gregory; Lepienski, Carlos Mauricio; de Souza, Gelson Biscaia; Kuromoto, Neide Kazue; Szameitat, Erico Saito; Peng, Ambrose Ngu See; Lee, Jia Yee; Claro, Ana Paula Rosifini Alves; Nugent, Michael J.D. (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 ...

    • Ti-25Nb-25Ta alloy treated by plasma electrolytic oxidation in phosphoric acid for implant applications
