Cellulose fibers isolated from oil palm empty fruit bunches (OPEFB) have been studied as a potential reinforcement for polyvinyl alcohol (PVA) biocomposite. Analysis of variance (ANOVA) showed that all three parameters—hydrolysis temperature, time and acid concentration, well their interactions—significantly affected the yield cellulose. Moving Least Squares (MLS) Multivariable Power (MPLS) mod...

Injectable and settable bone grafts offer significant advantages over pre-formed implants due to their ability to be administered using minimally invasive techniques and to conform to the shape of the defect. However, injectable biomaterials present biocompatibility challenges due to the potential toxicity and ultimate fate of reactive components that are not incorporated in the final cured pro...

This bibliographic review is focused on ligament tissue rehabilitation, its anatomy-physiology, and, mainly, on the dimensioning considerations of a composite material solution. The suture strength is problematic during the tissue recovering, implying reduction of mobility for several months. However, early postoperative active mobilization may enable a faster and more effective recovering of t...

To the article “Influence of Porosity on Fracture Toughness Hydroxyapatite/Multi-Walled Carbon Nanotubes Biocomposite Materials,” by A. N. Ponomarev, M. S. Barabashko, E. Rezvanova, and P. Evtushenko, Vol. 63, No. 11, pp. 1885–1890, March, 2021.

This work aims to design a synthetic construct that mimics the natural bone extracellular matrix through innovative approaches based on simultaneous type I collagen electrospinning and nanophased hydroxyapatite (nanoHA) electrospraying using non-denaturating conditions and non-toxic reagents. The morphological results, assessed using scanning electron microscopy and atomic force microscopy (AFM...

PLA biocomposites were prepared using three corn cob fractions and a wood fiber as reference. The composites were characterized by tensile testing, scanning electron microscopy (SEM) and polarization optical microscopy (POM). Micromechanical deformation processes were followed by acoustic emission measurements. The different strength of the components was proved by direct measurements. Two cons...

Induced damage during biocomposites drilling is significantly different to that produced on composites based synthetic reinforcement such as carbon or glass fibers. In reinforced with fibers, induced increases feed rate, however was observed decrease rate in natural This work focused the explanation of this differences between and traditional effect strain material behavior machining. A FEM mod...
