BACKGROUND Ideal bone repair material should be of good biocompatibility and high bioactivity. Besides, their mechanical properties should be equivalent to those of natural bone. The objective of this study was to fabricate a novel biocomposite suitable for load-bearing bone defect repair. MATERIAL AND METHODS A novel biocomposite composed of carbon fiber, hydroxyapatite and polyamide46 (CF/HA/...

Mango stone biocomposite efficiency for the removal of phosphate ions (PO4) from aqueous solution was investigated as a function of pH (2–8), biocomposite dose (0.05–0.40 g/100 mL solution), contact time (5–120 min), initial PO4 ions concentration (20–800 mg/L) and temperature (33–61 C). Maximum PO4 ions removal was achieved at pH 2, biocomposite dose 0.3 g, contact time 90 min and initial PO4 ...

BACKGROUND Osteoconductive additives are used in resorbable interference screws for anterior cruciate ligament (ACL) reconstruction to improve graft incorporation and mitigate adverse effects. There are no published studies that compare biological performances of bioresorbable and biocomposite screws without artifacts due to different follow-up times and intrinsic patient characteristics. PUR...

The development of hexavalent chromium remediating fibrous biocomposite mats through the immobilization of a hexavalent chromium reducing bacterial strain, Morganella morganii STB5, on the surfaces of electrospun polystyrene and polysulfone webs is described. The bacteria-immobilized biocomposite webs have shown removal yields of 93.60 and 93.79 % for 10 mg/L, 99.47 and 90.78 % for 15 mg/L and ...

The aim of this study was to evaluate the friction and wear behavior of ultra high molecular weight polyethylene (UHMWPE) against 3Y-TZP and a novel 3Y-TZP/niobium (Nb) biocomposite. The ceramic and the biocomposite materials were subjected to an accelerated aging process to evaluate the changes in the tribological behavior after this treatment. To carry out the tribological tests, a reciprocat...

Magnetic modification of microbial cells enables to prepare smart biocomposites in bioremediation. In this study, we constructed an efficient biocomposite by assembling Fe3O4 nanoparticles onto the surface of Sphingomonas sp. XLDN2-5 cells. The average particle size of Fe3O4 nanoparticles was about 20 nm with 45.5 emu g-1 saturation magnetization. The morphology of Sphingomonas sp. XLDN2-5 cell...

A conductive biocomposite film (MWCNTs-PANIFAD) which contains multi-walled carbon nanotubes (MWCNTs) along with the incorporation of poly(aniline) and poly(flavin adenine dinucleotide) co-polymer (PANIFAD) has been synthesized on gold and screen printed carbon electrodes by potentiostatic methods. The presence of MWCNTs in the MWCNTs-PANIFAD biocomposite film enhances the surface coverage conc...

Composite materials may be restricted to emphasize those materials that contain a continuous matrix constituent that binds together and provides form to an array of a stronger, stiffer reinforcement constituent. The resulting composite material has a balance of structural properties that is superior to either constituent material alone. Combining the advantages of inorganic and organic componen...

Flax fibres are oftenly used for reinforcing thermoplastic to manufacture biocomposite materials exhibiting numerous advantages such as high mechanical properties, low density and biodegradability. The mechanical properties of a biocomposite material depends on the nature and orientation of the fibres, the nature of the matrix and mainly on the adhesion between fiber and the polymer matrix. The...

The present work deals with the utilization of oil palm mesocarp fibre (OPMF) and poly(butylene succinate) (PBS) to produce cost-effective biodegradable materials. The biocomposite was prepared from OPMF and PBS at a weight ratio of 70:30 via a melt blending technique without addition of any additive. This biocomposite showed relatively low tensile and water resistance properties. As a conseque...
