The design of novel functional biomaterials that possess similar mechanical attributes as human bones, accompanied with admirable osteogenesis to replace conventional metallic implants would be an intriguing accomplishment, especially in the orthopedic, craniomaxillofacial and dental fields where biointerfaces with outstanding osseointegration are in high demand. Guided by this purpose, in the ...

In this research, the effect of different biopolymers such as polyethylene glycol (PEG) and polyvinylalcohol (PVA) on synthesis and characterization of polymer/cobalt ferrite (CF) nano-composites bymechanical alloying method has been systematically investigated. The structural, morphological andmagnetic properties changes during mechanical milling were investigated by X-ray diffraction (XRD),Fo...

In this study, polyaniline-graphene composites with different nano-structures are synthesized and the behaviour of the obtained composites serving as electrode materials in electrochemical capacitors is studied. The morphology, crystal structure, and thermal stability of the composites are examined using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Thermal gravimetric analys...

Additions of high modulus nano particles to Aluminum alloys offer the potential to develop a lightweight composite with high mechanical properties. It is extremely difficult to disperse nano-sized ceramic particles uniformly in molten metal. In order to investigate the effect of nano-alumina on the microstructure and mechanical properties of composite, a new method was used in stir casting to a...

Metal matrix composite (MMC) is engineered combination of the metal (matrix) and hard particle (reinforcement) to get tailored properties. MMCs are either in use or prototyping for the space shuttle, commercial airliners, electronic substrates, automobiles, golf clubs, and a variety of other applications.In this study, carbon nanotubes (CNTs) reinforced aluminum MMCs were synthesized by DPDS fo...

This paper focuses on application of co-axial electrospinning technique to the development of nanofiber reinforced transparent composites. Investigations have been done on fabrication and functionalization of the transparent composites with improved mechanical properties, thermal properties and shielding ability for ultraviolet radiations. In the fabrication, PMMA, a polymer with excellent visi...

the purpose of this study was to evaluate effects of nano-clay particles and oxidized polypropylene as compatibilizer on the decay resistance of wood plastic composite against coriolus versicolor fungi. in order to provide oxidized polypropylene as compatibilizer, polypropylene was oxidized in the presence of air oxygen in 2 hours by internal mixer. afterwards, wood fibers, polypropylene, nano-...

BACKGROUND Diarrhea in piglets is one of the main causes of animal death after weaning; zinc oxide (ZnO) has been used in high doses for the control of this sickness. The aim of this study was to determine the physicochemical properties of ZnO nanoparticles synthesized and immobilized on a chitosan/alginate (CH/SA) complex and investigate the antimicrobial activity and in vitro release profile ...
